independent per channel. This allows for quick enabling or disabling of a group without losing group

routings.

● Mute/Arm: Only channel mutes and arms are grouped.

● Trim/Fader: Trim, fader, record arming, limiters, and mutes are grouped. Trims can only be grouped

when all channels of the group share the same gain range. Gain ranges depend on input type routed

to a channel. See Channel Screen>Channel Trim Value for more detail.

● Fader: Fader groups act just like Trim/Fader groups, but trims remain independent per channel.

Four channel groups are possible; channels grouped can only be assigned to one group.

6.8.1 Dugan Automixer Mode

Dugan gain display bars are overlaid on top of the channel signal meters. The top 15 dB of the meter scale is shared

between Dugan gain display bars and audio signal metering. Dugan gain display bars range from 0 dB (at the top,

833 User Guide Menus

aligned with 0 dBFS, no attenuation) to -15 dB (max attenuation). The -15 dB value is indicated by a purple horizontal

graticule mark near the top of a channel’s signal meter when that channel is enabled for Dugan in Menu>Automixer.

There are two independent Dugan processing groups, Bus L and Bus R. Channels 1-16 can be routed to Bus L, Bus

R, both equally (Center), or both unequally (L or R pan increments) by using a channel’s pan control.

To show which Dugan group the channel is in, the Dugan gain display bar is left-aligned for fully L, right-aligned for

fully R and center-aligned for any other pan value. When a channel is routed to both Dugan groups (Bus L and R), the

center-aligned gain display bar shows the least attenuated value.

The Channel Screen shows the Dugan gain display bar overlaid within the horizontal channel meter. The Dugan gain

display scale and indication is the same as in the main meter screen.

The ring LEDs for ch 1-12 show Dugan gain for ch 1-12. The ring LEDs begin to glow purple at 15 dB attenuation and

increase in intensity at 0 dB attenuation.

6.9 Noise Suppression

Suppress background noise instantly on-location with the optional CEDAR sdnx or Sound Devices NoiseAssist plugins

for 8-Series mixer-recorders.

6.9.1 Cedar sdnx

Over the last few decades, CEDAR has become synonymous with real-time, low-latency, and artifact-free audio

restoration and noise suppression. CEDAR Audio Ltd.’s sdnx brings CEDAR’s highly regarded noise suppression

technology to 8-Series mixer-recorders. This optional plugin reduces unwanted background noises so you can better

capture dialog.

CEDAR sdnx has near-zero latency and one simple control for adjusting the amount of suppression. Up to 8 instances

of CEDAR sdnx are available per mixer-recorder/device. These instances can run on any combination of isolated

channels or bus. The plugin functions at sample rates up to and including 96 kHz.

Previously, using CEDAR with an 8-Series mixer-recorder required a separate hardware unit like the CEDAR DNS 2.

This collaboration between CEDAR and Sound Devices marks the first time CEDAR technology has been available in-

unit for any portable mixer-recorder. Now, even ultra-light portable recording setups have access to CEDAR noise

suppression.

CEDAR sdnx requires 8-Series firmware v7.40 or higher. Want to try before you buy? The 2-instance version of the

plugin is available as a demo on 8-Series running v7.40 or higher.

6.9.2 Sound Devices NoiseAssist

NoiseAssist is an advanced signal processing algorithm that reduces background noises such as traffic, generators,

HVAC noise, and more. The plugins continuously monitor background noise to give you clean audio for the entire take.

Using NoiseAssist is easy and fast - simply adjust the amount of background noise to suppress and NoiseAssist will do

the rest. Suppression happens in real time with just 1 ms of latency - no “learning” required. Depending on the plugin

purchased, two-, four-, or eight- instances of NoiseAssist can run on any combination of isolated channels and/or any

bus.

This algorithm is optimized specifically for high-end professional film and television dialog. It accurately distinguishes

the desired speech signal from background noise using proprietary advanced multi-band frequency, level, and

statistical calculations. NoiseAssist maintains the excellent frequency bandwidth of the audio channel, while effectively

suppressing the background noise and reverberation.

833 User Guide Menus

NoiseAssist Plugins are available for purchase at store.sounddevices.com

Try the two-instance version of NoiseAssist Plugin in demo mode (tone bursts replace audio every 10 seconds) until

the NoiseAssist Plugin license is purchased and installed. The NoiseAssist demo mode is disabled when the 8-Series

is powered down.

Mode

Selects NoiseAssist or CEDAR sdnx and whether Noise Suppression is disabled* or enabled.

The Noise Suppression field in the channel and bus screens shows as NA when NoiseAssist is active and NX when

CEDAR sdnx is active.

Note: Set a toggle shortcut or mapped controller button to enable/disable Noise Suppression to allow you to quickly

compare the effect of it being on or off.

Channel/Bus Selection

Selects up to eight (depending on plugin installed) instances of Noise Suppression and which channels 1-16 and/or

Buses it is applied to. If the maximum number of instances are already selected, deselect one instance before

selecting another.

Note: Noise Suppression only affects the mix of ISOs and return bus sources when applied to buses receiving audio

from L, R, B1, B2 buses.

Note: NoiseAssist and CEDAR sdnx cannot be used at the same time.

NoiseAssist is only available at sample rates of 48.048 kHz and less.

CEDAR sdnx is only available at sample rates of 96 kHz and less.

Adjusting Noise Suppression

In the Noise Suppression menu, ensure Noise Suppression is enabled, and the required channel and/or bus is

selected.

For a Channel (1-16): Enter the channel screen using the PFL toggle. Use the Select knob to scroll to and enter the

NoiseAssist (NA) or CEDAR sdnx (NX) field. Rotate the Select knob to set the amount of Noise Suppression applied to

the channel.

833 User Guide Menus

For Bus L, R: Go to Menu>Buses and select Bus L or Bus R, whichever has been enabled for Noise Suppression.

Push the */** toggle to the right to select the NA or NX parameter and rotate the Select knob to set the amount of

Noise Suppression applied to the bus.

For a Bus B1-4: Go to Menu>Buses and select Bus 1-4, whichever has been enabled for Noise Suppression. Push

Tone toggle to display more options, then push the */** toggle to the right to select the NA or NX parameter and rotate

the Select knob to set the amount of Noise Suppression applied to the bus.

Noise Suppression values range from 0 dB to -20 dB with 0 dB representing no noise attenuation and -20 dB being the

maximum amount of noise attenuation.

Channels or Buses enabled for Noise Suppression show a diamond in their meters. The diamond moves based on the

amount of Noise Suppression averaged across all the frequency bands that have signal in them.

The lower the diamond on the meter scale, the more the background noise is being attenuated. The diamond moves

towards the top of the scale as the audio signal changes (for example, when a mic picks up dialog) - this indicates that

the Noise Suppression algorithm is learning and adapting to the signal in real-time.

833 User Guide Menus

To effectively use Noise Suppression, start with the default setting of -6 dB and dial in more or less depending on your

environment. An ideal setting will reduce the background noise without coloring the sound.

Note: NoiseAssist and CEDAR sdnx are not automatically linked when channels or buses are linked.

6.12 Record/Play

The 12-track (16-track with +4 plugin) 833 is capable of recording and playing back audio at up to 192 kHz sample rate

with a fixed bit depth of 16-bit or 24-bit or a floating bit depth of 32-bit floating point at up to 96 KHz. This versatility

allows the 833 to be used in a myriad of applications from dialog and voice recording, to live music recording, to sound

FX capture.

Sample Rate

Determines the record and playback sample rate. Select from [44100, 47952, 48000*, 48048, 96000, 192000 Hz].

Bit Depth

The 833 can record the following:

● Fixed bit depth (16-bit, 24-bit) for ISO tracks or bus tracks (L, R, B1, B2).

● Floating point (32-bit) for ISO tracks. Bus tracks (L, R, B1, B2) cannot be recorded in 32-bit floating point.

● Combined fixed and floating point: 16-bit or 24-bit bus tracks along with 32-bit floating point ISO tracks.

Fixed bit depth is set in the Bit Depth menu. 32-bit floating point is enabled for ISO tracks in the Track to Media menu.

Why 32-bit Floating Point?

The key benefit of 32-bit floating point recording is the elimination of distortion due to digital overload/clipping i.e.

signals that exceed 0 dBFS. It is an excellent technology for recording audio sources that have unpredictable level and

wide dynamic range, everything from jet fly-overs to voices suddenly changing from a whisper to a scream.

32-bit Floating Point for Dialog Recording

In traditional dialog recording, analog limiters are frequently used to prevent digital overload when an actor

unexpectedly shouts or screams. High quality analog limiters such as those in the 8-Series do a fantastic job of

preventing digital overload distortion. However, the fact remains that a limiter by its very nature, introduces distortion,

albeit a more natural and acceptable distortion than the digital overload distortion it prevents. This is where 32-bit

floating point comes in because it allows signal to exceed 0 dBFS without digital overload distortion. It provides a

distortion-free alternative to using 24-bit with analog limiters for capturing unpredictable and wide dynamic range voice

sources.

Although 24-bit fixed recordings have a dynamic range of ~144 dB (which is more than adequate for capturing the

dynamic range of most audio sources), if source levels swing wildly and unpredictably from super quiets to super

louds, it is challenging to know where to set microphone preamp trim gain levels. Production sound mixers typically set

trim gain levels such that normal dialog levels are at -20 dBFS, peaking to around -12 dBFS allowing for a headroom

of 12 dB for those occasional excessive loud sounds. Analog limiter thresholds are typically set at around -3 to -4

833 User Guide Menus

dBFS to prevent these excessive louds sounds from causing digital overload. The analog limiter distortion is much less

offensive than digital overload distortion. To avoid overload distortion altogether in 24-bit recording, the sound mixer

would have to work with a lot more headroom, possibly as much as 40 to 50 dB. However, delivering audio files at

such a low nominal level could be problematic for postproduction workflows. With 32-bit floating point, you can deliver

distortion-free audio files at normal levels.

Considerations when recording in 32-bit Floating Point with the 8-series:

● Only ISO tracks can be recorded as 32-bit floating point wav files.

● Bus tracks (L, R, B1, B2) are always recorded as fixed 24 or 16-bit.

● A maximum of 2 media can be recorded to when operating in 32-bit floating point.

● Maximum sample rate is 96 kHz when operating in 32-bit floating point.

● 32-bit floating point ISO recorded tracks are unaffected by limiters, compression, EQ, noise suppression, and

auto-mixing even if those processes are enabled. Channel limiting, compression, EQ, noise suppression, and

auto-mixing only affect the ISO paths into the mix busses and outputs.

● 32-bit floating point ISO recorded tracks are affected by HPF, delay and polarity.

● When 32-bit floating point is enabled, only pre-fade ISO routing is allowed.

● When 32-bit floating point is enabled, the Home screen’s frame rate field alternates with the bit-depth status

every 3 seconds.

● 32-bit floating point is not permitted when AAC is enabled.

Recommendations when recording in 32-bit Floating Point:

● Although most modern NLEs and DAWs support 32-bit floating point wav files, it is recommended to liaise with

post-production to ensure they meet their workflow criteria.

● Continue to gain stage as you normally would when recording 24-bit.

● It is recommended to enable limiters on ISO channels to prevent clipping in their pre and post fade paths into

the fixed bit mix busses (L, R, B1, B2) and outputs. Even with limiters enabled, 32-bit floating point ISO tracks

are still recorded limiter-free.

● Warning: the HP output may still clip when monitoring >0dBFS signals.

Pre-roll Time

Selects the amount of Pre-roll recording. Adjustable in 1 second increments. *0 s [0-10 s]

Post-roll Time

Selects the amount of post-roll recording. Adjustable in 1 second increments. [0-10 s] If a recording is stopped

prematurely, press record within the post-roll time. The machine will continue to record into the original file. Useful for

when directors call ‘cut’ prematurely. During the post-roll period, the transport joystick ring LED shows orange.

Pressing stop again during the post-roll period cancels the post-roll and stops recording.

Stop Hold Time

Selects how long Stop must be pressed before record or playback stops. Useful for preventing accidental termination

of recording or playback.

Track to Media Menu

Selects the sources for each recording media as well as the type of file recorded. Tracks may be routed to media to be

recorded as AAC (LR or Bus 1,2 only), WAV Mono, or WAV Poly files. (Green text box= WAV Mono file, blue text box=

WAV Poly file, orange text box = AAC).

ISOs can be set to record as 32-bit floating point wav files by activating the ‘32b Float’ box. When activated, the LR

and B1B2 mix tracks continue to be recorded at the bit depth selected in the Bit Depth field (item 2 in the Record/Play

menu).

Note: 32b float option is not permitted in the following situations:

6.15.1 The SL-2

The SL-2 (shown above on an 833) is a two slot-in wireless receiver integration system that easily mounts to the top

panel of any 8-Series mixer-recorder. It accepts UniSlot and SuperSlot™ wireless receivers from a variety of

manufacturers. Power to the SL-2 and receivers is supplied by the 8-Series Mixer-Recorder – no external DC

connector is needed on the SL-2. Analog or digital audio is sent from the receivers into the mixer-recorder via the

expansion port, reducing messy cabling for power and audio connectivity.

The SL-2 offers antenna distribution to slot-in receivers, spreading out the placement of antennas for better RF

performance. Additionally, the SL-2 allows for control of smart antennas and includes two filtered antenna outputs to

external receivers via MCX ports. The rear panel of the SL-2 is equipped with two TA3 connectors for an additional

four inputs of AES3 audio and two 4-pin Hirose DC Outputs, each supplying up to 500 mA.

Up to eight channels of audio can be routed from the SL-2 to the 833. The eight channels can be comprised of audio

from dual or quad channel slot in receivers and/or the four AES inputs.

The SL-2 mounts to the 833 via the multi-pin expansion port located on the top panel. Please refer to the SL-2 User

Guide for panel descriptions and installation instructions.

Powering the SL-2

The SL-2 is powered by the 833 via the Expansion Port. No additional power source is needed to power the SL-2.

To activate the SL-2, set the System>Expansion Port menu to On.

Save power when the SL-2 is not in use by setting the Expansion Port menu to Off. When the Expansion Port is set to

Off, the SuperSlot menu is grayed out.

Routing SL-2 Sources to Channels

The SL-2 has 12 selectable sources and can send up to 8 channels of audio to the mixer/recorder. 8 channels are

available if all sources are AES digital. If a slot receiver output is analog, 6 channels are available and AES 3 and 4

cannot be selected.

To route an SL-2 Source to a channel, access a channel’s source screen and select from A1-A4, B1-B4, AES 1-4.

When A1-A4, B1-B4 are selected as source, use the */** toggle as a shortcut to the selected receiver’s setup screen.

For SL-2 A1-A4, B1-B4, and AES 1-4 sources, channel trim gain range is -20 to 50 dB.

When an A10-RX/A20-RX is receiving signal from an A20 transmitter, the trim gain of the associated 8-Series channel

is 0 to 60 dB.

RF Overload LEDS

Each antenna input on the front panel of the SL-2 has an associated LED that displays incoming RF level status.

 Red = approaching RF overload threshold of the SL-2

 Orange = approaching overload threshold of digital wireless systems

 Off = no overload

To disable the LEDs go to SL-2 Options>Antenna LEDs and set to Off.

Selects whether the fader gains are displayed in the controller’s display. [Off, On*]

Applies to CL-16 and 3rd party controllers, and SD-Remote.

6.17.3 Soft Fader/Trim Pickup

[Off*, On] When enabled, physical faders and trims on the 8-Series front panel, CL-16, CL-12, and some 3rd party

controllers with non-motorized faders resume gain control only when their physical position reaches the last stored

gain value. This prevents sudden jumps in gain levels when setting gains from more than one control interface.

Note: Last stored gain values are held over a power cycle and may require the adjustment of a physical fader or trim

control to pick up the last stored gain value.

Note: Soft Fader/Trim Pickup also works in conjunction with the SD-Remote. The 8-Series trim/faders pickup control

only once they have reached the last gain set in SD-Remote.

When Soft Fader/Trim Pickup is Off and a controller is connected, the 8-Series front panel controls are disabled unless

controlled by SD-Remote. Use SD-Remote Hide Faders function to prevent SD-Remote changing fader gains

accidentally.

Note: When a non-motorized fader controller and SD-Remote are both used at the same time, the controller will not

soft pickup fader or trim control.

6.17.6 CL-16 GPIO

The CL-16’s 10-pin Phoenix connector labeled Remote provides eight GPIO ports. These can be configured as simple

contact-closure inputs, and to drive low current draw components such as LEDs and logic-controlled powered relays.

CL-16 Remote Pin Functions

 Ground (-): for triggering logic-low connections.

 1 - 8: Configurable as inputs or outputs, activate high or low, and assigned a function.

 +5 V DC: for triggering logic high connections. Supplies 1A at 5V.

Active High inputs trigger when +5V is applied.

Active Low inputs trigger when ground is applied.

Active High outputs go to 5 V when the mapped function is active.

Active Low outputs go to ground when the mapped function is active.

The GPIO lines can supply or sink 10 mA through the series 100-ohm internal resistance. This is not enough to directly

drive relays but is enough for driving logic-controlled powered relays.

GPIO Outputs can be used to drive LEDs with a proper series resistor. Resistor values vary from LED to LED, 470

ohms is a good starting point.

Although the CL-16 has protection against ESD (static electricity), highly inductive loads (like relays, bells etc) may

require extra diode protection to protect against inductive voltage spikes. Make sure to protect the CL-16 with an anti-

parallel diode across the coil of what is being driven.

6.17.8 Third Party Controllers

1. Require Shift for Arm: When selected, “Shift” on external control surface must be pressed simultaneously with

“Rec” to arm tracks. [Off*, On]. Applies to supported 3rd party controllers only.

2. Require Shift for Mute: When selected, “Shift” on external control surface must be pressed simultaneously

with “Mute” to mute channels, buses, and outputs. Applies to supported 3rd party controllers only.

3. Main Fader: Sets which bus or output a third-party controller’s main fader controls.

4. Multiple Controllers: When multiple controllers are simultaneously connected to the 833 via a USB hub, sets

whether they operate in Spill or Individual mode.

a. SPILL: In Spill Mode, all MCU controllers connected to the 833 work as one big control surface. All

controllers operate in the same mode (e.g. Mix Mode, Bus Mode, Output Mode etc), all channel strips

join into a single fader bank spilled across all controllers, and all controlled parameters spill across all

available channel strips. For example, with the +4 plugin installed, a setup with two 8-fader controllers

spills faders 1-8 to controller 1 and faders 9-12 to controller 2. The USB Hub port number determines

which controller is Controller 1 and which is Controller 2. Controller 1 must be connected to a lower

USB port number than Controller 2. On most hubs, the USB port numbering is not marked in which

case, try the various ports to determine the hub’s USB port numbering.

b. INDIVIDUAL: In Individual Mode, each controller behaves independently with its own operating mode

and fader bank. For example, this allows using one controller for the main channel mix in Mix Mode

and a separate controller for setting up IFB feeds in Bus Mode or Bus Sends on Faders Mode. A third

controller could be used for output control in Output mode.

6.17.8.1 Control Modes

A Control Mode determines the function of a 3rd party controller’s faders, VPots, and other buttons.

VPots are the multi-function encoder knobs positioned above each channel’s fader.

Mix Trim Mode (Home). For mixing channels to the main LR bus. Switches faders to channel faders and VPots

to channel trims. Mutes and Solos buttons are channel mutes and solos respectively.

Fat Channel Mode. For editing various channel parameters including Trim, Pan, Source, Delay, Phase, Limiter,

HPF, EQ, and Bus Sends.

Mix Pan Mode. For adjusting channel pans by rotating the VPots. Press a VPot to set pan to center. Faders,

mutes and solos continue to control the channel mix, mutes and solos.

Mix Low Cut Mode. For adjusting channel low cut frequency by rotating the VPots. Press a VPot to toggle Low

Cut On/Off. Faders, mutes and solos continue to control the channel mix, mutes and solos.

Bus Mode. For adjusting Bus levels B1-B4, L, R. Switches faders to Bus faders. Mutes and Solos buttons are

Bus mutes and solos respectively.

Bus Sends-on-Faders Mode. Faders are channel sends to the selected bus. Ideal for creating different IFB

feeds/mixes.

Channel Bus Sends Mode. VPots adjust a channel’s send gains to each bus. Press VPot to toggle between Off,

Pre, Post and Send. Rotate VPot to adjust bus send gain. Use the Select buttons to select which channel’s send

gains to adjust.

Output Mode. For adjusting Output levels X1-X4, L, R. Switches faders to Output level controls. Mute buttons are

output mutes.

EQ Mode. For adjusting channel EQ using the VPots. Use the Select buttons to select which channel’s EQ to

adjust. Faders continue to control the channel mix.

Chapter 14: Glossary

¼-inch jack

Common analog audio connector used as both an audio input and output. When a ¼-inch jack is described as TRS

(tip-ring-sleeve) it can be wired as either a balanced connection or as a two-channel connection. ¼-inch headphone

jacks are typically wired as TRS stereo jacks.

3.5 mm jack

Common small-format audio connector. Often used for headphones and -10 dBV signals for portable audio devices.

Advanced Audio Coding (AAC)

An audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC

generally achieves better sound quality than MP3 at the same bit rate.

AES3

A standard for the exchange of digital audio signals between professional audio devices. An AES3 signal can carry two

channels of PCM audio over balanced, 110-ohm interconnections. AES3 is most commonly interconnected with XLR-3

cables.

AES42

A digital interface protocol for microphones and microphone inputs. Microphones conforming to this standard directly

output digital audio through an XLR or XLD male connector, rather than producing an analog output. AES42

microphones require powering.

Attenuation

A reduction in the level of an audio signal. Attenuation can be applied to both analog and digital signals. A fader is

used primarily to attenuate signals, though a small amount of positive gain is often available on a fader.

bEXT chunk

Broadcast WAV extension data added to the audio data in a WAV file. The bEXT chunk includes timecode and user bit

data. For systems that do not recognize the bEXT chunk this additional information is ignore

Bit depth

When converting between analog and PCM digital audio the amplitude of an analog signal is measured in finite steps,

measured in bits. Higher bit rates result in greater resolution of amplitudes, resulting in higher dynamic range. 24-bit

audio, with a theoretical maximum dynamic range of 144 dB, is the standard bit depth used throughout the audio chain

for production. 32-bit floating point has a theoretical dynamic range of ~1500 dB and can capture sound levels

exceeding 0 dBFS.

Broadcast WAV, BWAV

Broadcast WAV files are WAV files with additional, non-audio data, such as bEXT chunk data. Broadcast WAV files

offer timecode support.

Bus

An audio path that is the destination of one or multiple (mixed) channels. A bus is typically routed to an output, a

record track, or both.

Camera return

An audio input on a mixer designed to receive the output, typically the headphone output, of a camera. Camera return

inputs allow the user to monitor the level and quality of the signal received at the camera. On the 833 the Aux In can

be used as a source for any channel.

CEDAR sdnx™

CEDAR Audio Ltd.’s highly-regarded noise suppression technology is available as an optional paid plugin from

store.sounddevices.com. Use CEDAR sdnx to reduce unwanted background noises so you can better capture dialog.

CEDAR sdnx has near-zero latency and one simple control for adjusting the amount of suppression. Up to 8 instances

of CEDAR sdnx are available per mixer-recorder/device. These instances can run on any combination of isolated

channels (excluding 17-32 on 833) or bus.

Channel

A “slot” of a mixer that is controllable and routable. A given input feeds the channel and the channel’s settings process

and route the audio as required. It can also be thought of as the path its selected input signal takes on its way to its

record track, a bus, or an output.

Channel grouping

With the 833 all of the 8 channels can be grouped together so that their faders, record arming state mute states can be

controlled together. Channel grouping can be used as an alternative to sending channels to a bus.

Circled take

An identifying character, the @ symbol, which is placed in the file name to highlight a take. Circled takes can either be

used to identify good takes or to identify tracks or takes that will be ignored

Com return

A dedicated audio input designed to receive signals from a PL, or private line communications circuit. The com return

on the 833 can routed to an output or a bus.

Com send

A dedicated output designed to send signal to a PL (private line, talkback) communications circuit. The com send is

toggled by a front panel switch.

dBFS

A measurement of the signal level of a digital signal in dB increments, dB relative to full scale signal. The maximum

signal in dBFS is 0 dBFS, with signals expressed with a negative sign. dBFS signal strength is an internal

measurement and does not correspond to analog signals unless the relationship between analog signal and digital

signal is known.

Delay (channel)

Time delay that can be applied to an individual channel. Channel delay, typically set in milliseconds, is often used to

compensate for different acoustical or electrical arrival times of signals between channels.

Dugan Automix

An automatic mixing algorithm invented by Dan Dugan which when used across multiple microphone inputs for

speech, makes decisions about which inputs should be given priority due to speech being present vs. open, but

unused inputs. This allows for greatly improved audio by turning down the inputs that aren’t used and automatically

turning up the inputs that are being used in real-time and transparently

exFAT

A storage volume format that can be read and written from current versions of MacOS and Windows. exFAT supports

volume sizes up to 128 PB (gigantic), and individual files can have a maximum size of 16 EB (even more gigantic,

bigger than the maximum volume size).

833 User Guide Glossary

117

Fader

A physical control on a mixing console, either a rotary or sliding potentiometer, that controls the level of a channel to a

bus. Most faders have more attenuation than gain available and a unity gain position where the input trim level

established the level to the bus.

False take

A recorded take that was either erroneously recorded, or a take that needs to be repeated. It can be labeled after

recording. An identified false take is moved to the trash bin and the auto-incrementing take number is reset to the

value prior to the false take.

ile list

Every file recorded by a recorder is visible in the file list. It can be viewed either on a recorder or from a computer when

the recording volume is mounted. The file list shows all the individual files recorded by a recorder.

Frame rate

The rate at which video or motion picture images are recorded or played back, measured in frames-per second (FPS).

All audio and video devices must be running at the same frame rate to keep audio and video synchronized. Timecode

frame rates are either an integer or non-integer value. Integer values include 24, 25, and 30 FPS. Non-integer frame

rates include 23.976 and 29.97, and 29.97 drop FPS.

Frequency

The period at which a wave oscillates, measured in hertz (Hz). Frequencies audible to humans range from 20 Hz for

very low frequency signals to 20 kHz for very high frequency signals.

Gain

An increase (or decrease with negative gain) in the level of an audio signal. Gain can be applied in several locations,

to both analog and digital signals. In a field mixer the microphone preamplifier provides a substantial amount of gain at

the trim to raise the low level microphone signal to a usable signal in the mixer. Gain is also available at the fader.

Gain of digital signals or line level analog signals is often limited. Unity gain is gain stage that neither adds or subtracts

level from a signal.

Headphone monitor

Often a separate bus with a dedicated headphone volume control, the headphone monitor typically is normalled to the

main left/right output bus of a mixer. Headphone sources can often be selected among soloed tracks or buses. In

some products complex headphone monitoring of MS Stereo, LR stereo, and ambisonic sources is available.

High pass filter (audio)

Also referred to as a low-cut filter, this circuit reduces the amount of low frequency content in an audio signal. A HPF is

particularly useful when recording speech since the human voice does not generate appreciable energy at low

frequencies. The HPF reduces non-speech signals such as environmental noise, wind noise, and microphone handling

noise, improving the intelligibility of speech and reducing low frequencies from overloading the input. The high pass

filter is placed in the circuit close to the microphone preamplifier.

High pass filters are often frequency selectable, ranging from 20 Hz to 200 Hz. HPF also have a slope, generally from

3 dB/octave to 18 dB/octave. Greater/steeper slopes offer more attenuation of frequencies just below the set filter

frequency.

Input

The physical connection and associated signal type from external sources connected to a device. Inputs can include

microphone inputs on XLR connectors or USB audio inputs from a computer. Depending on the architecture of the

mixing console its inputs may be hardwired to channels or channels can be selected from different inputs.

Input limiter

A limiter circuit reduces the peak signal levels of audio, generally to prevent signal overload. Analog inputs have a

maximum input signal level that can be reached before overload/distortion is introduced. Setting the input gain

correctly so that input signals do not reach this maximum level prevents most overload conditions. In the presence of

very high, unexpected signals an input limiter changes the gain of the incoming signal and prevents it from

overloading. Input limiters are sometimes compressor-type circuits with a ratio of infinity:1, meaning that any increase

to the input signal into the limiter at the limiter threshold does not increase the output signal of the limiter.

Several parameters may be available in a limiter, including knee, ratio, release, and threshold.

Isolated track

A recorded track of an individual microphone or sound source. “Iso” recordings allow for post-record mixing of

individual sound elements.

iXML

An extensible data schema for audio and related metadata stored in broadcast WAV files. Manufacturer-specific data

generated during recording is stored in iXML.

Line level

An analog audio signal used to interconnect audio equipment. Line level may be balanced or unbalanced, referenced

to +4 dBu or -10 dBV, professional or consumer respectively.

Low cut filter

See high pass filter.

Microphone level

The audio signal generated by a microphone. Mic level signals are very low level, requiring a microphone preamplifier

to bring them to usable, line levels. Interconnects with microphone level signals can be subject to noise and

interference.

Mid-side linking (inputs)

When mid-side (MS) stereo inputs are used and the inputs are set to MS linking and MS decoder is activated for those

inputs. This yields a stereo signal with one fader controlling overall input level and control for the “width”, or amount of

the side signal added. With an MS matrix at the input, the signal is sent to an output bus as left/right stereo. Mixers

with MS matrices often allow for discrete mid and side signal recording. In that case the MS decoder can be activated

at the headphone selection to monitor left/right stereo.

MixAssist™

An exclusive Sound Devices automatic mixing algorithm which when used across multiple microphone inputs for

speech, makes decisions about which inputs should be given priority due to speech being present vs. open, but

unused inputs. This allows for greatly improved audio by turning down the inputs that aren’t used and automatically

turning up the inputs that are being used in real-time and transparently.

Mix track

A recorded track that is a sum of multiple tracks. In production sound the mix track is often a single summed track of all

production dialog elements. Mix tracks can also be sub-mixes of like microphones, such as a sub mix of just lavalier

microphones or just boom microphones.

Monophonic WAV

A WAV file that is comprised of a single track of audio. When recording multi-track audio with monophonic WAV files

each track is recorded to its own WAV file, with a file name indicating the track number. All associated monophonic

files that are part of a multi-track recording will be identical lengths.

833 User Guide Glossary

Mute

A mute control is a convenient on/off switch for a channel and an easy way to remove a channel from appearing in

downstream buses. Mute an input or channel does not change levels or settings; when channels are muted and

unmuted, their settings remain.

Notes (metadata)

A metadata field that is saved along with audio data in a recorded sound file, useful for sound report generation. Some

workstation software recognizes the notes field and presents it when viewing the sound file.

NoiseAssist™

An exclusive Sound Devices noise suppression algorithm which is available as an optional paid plugin from

store.sounddevices.com. Use NoiseAssist to suppress background noises such as traffic, generators, HVAC noise,

and more. The plugin continuously monitors background noise to give you clean audio for the entire take. Up to eight

instances of NoiseAssist can run on any combination of isolated channels (excluding 17-32 on 833), bus L, or bus R.

NP-1(A) battery

A specific class of battery, originally developed by Sony. There are multiple chemistries in this class including lithium-

ion and nickel-cadmium.

Output

The physical connection and associated signal type sent from a device. Outputs can be source from inputs, buses,

record tracks, and other auxiliary signals.

Output auto-mute

When set, an output signal is muted when recording is stopped, restricting program audio from being sent to listeners

“between takes”.

Output delay

A digital delay applied at the output. Signal delay is often set at an output to compensate for the delay introduced by

digital imaging systems so that picture and sound remain in correct “lip sync”. Output delay is set in either frames or

milliseconds.

Pan

When a channel is routed to a stereo-linked bus the level it appears at each bus is adjusted by a pan control. A

channel with its pan control “straight up the center”, or “centered” sends signal at the same level to each bus. A

channel that is panned left or right sends the signal to the left or right bus, respectively.

PFL, pre-fade listen

When an input or channel is selected for monitoring/solo with a PFL, the channel is routed to the headphone output

before the channel fader so that the fader position has no effect on the headphone level. Trim/gain changes to the

input will change the headphone output.

Phantom power

Condenser (capacitor) microphones require power for operation. They use power to charge the diaphragm backplate

(for true condensers) and power the impedance convert located adjacent to the microphone capsule. Phantom power

is the method for microphone inputs to supply DC power to the microphone through the same connection used for the

audio signals from the microphone.

Phantom power provides a positive voltage, typically between 11-52 VDC, with 48 V being the most common, on both

pin-2 and pin-3 with pin-1 used as ground. The DC voltage appears as a common-mode signal on the balanced

connection and is rejected by the connection’s differential amplifier. Phantom power has no effect on dynamic

microphones.

833 User Guide Glossary

120

Phase

The relationship one audio signal has in time with respect to another audio signal, defined in degrees of phase. When

audio signals are generated at identical times, they are “in phase” with each other. When one audio signal is time-

delayed with respect to another the signals are “out of phase”. Differing phase relationships can be introduced several

ways, including when microphones are placed at varying distances from a sound source, or electrical/digital delay is

introduced to one signal with respect to another.

Phrase

A pre-set text string which can be used to quickly fill out the notes field.

Pre-fader routing

The signal from a channel is routed to a bus before the fader in the signal path. The input trim, if available, controls the

channel level sent to the bus. Isolated tracks are typically recorded pre-fader so that any level changes made to the

faders don’t affect the recorded signal.

Pre-roll

A continuous buffer that is always writing to memory offering a recording that begins prior to when the record button is

activated. Pre-roll is set in seconds, and the recording begins the set number of seconds prior to the button being

pressed. This is helpful in applications where an operator missed a cue to begin recording.

Polarity (audio)

The direction of the current flow of an audio signal is defined as polarity. The polarity of a signal can reversed when a

balanced audio signal connection has its pin-2 and pin-3 connections reversed. Single-ended signals can have their

polarity reversed when going through an “inverting” gain stage. It is best practice to have all incoming and outgoing

signals with the same polarity relationship.

Polyphonic WAV

An individual WAV file that contains multiple audio tracks. When recording multi-track audio with polyphonic WAV files

all recorded tracks are contained within a single WAV file.

Post-fader routing (after fade routing, AFL)

The signal from a channel is routed to a bus after the fader in the signal path. The fader controls the level of the

channel at the bus. Channels sent to a master bus, such as the left/right bus, are typically sent post-fader.

Post-roll

An extra period of time that is appended to the end of a recording when stop is pressed. If record is pressed during this

period of time, recording will resume within the same file with no audio lost. This is particularly useful should a Director

call ‘cut’ prematurely or accidentally.

Project

An option available for file organization on Sound Devices recorders. Projects are the highest level of file folder

organization. The project folder can contain sub-folders of scene files or recorded files directly.

Record bell

A tone generated in headphones to alert the listener that recording has started. The bell is also produced when

recording has ended with the stop button, when the recording volume is full, or when power is in a critical state.

Record Folder

833 User Guide Glossary

121

The destination folder for recorded takes. The 8-Series supports a three-tier folder hierarchy allowing for flexibility in

organizing recordings.

Sampling rate

When converting between analog and PCM digital audio the analog signal is measured (sampled) in unique steps at a

data rate specified in kHz. Higher sampling rates allow for representing higher frequency analog audio. 48 kHz is the

standard sampling rate for production, worldwide. Higher sampling rates including 96 kHz and 192 kHz are used for

high-precision applications where the representation of audio above 20 kHz is required. A general rule is that the

maximum analog audio frequency is ½ the sampling rate.

Scene

On Sound Devices recorders the scene becomes part of the file name for a take. Scene names can be pre-loaded to

quickly change between scenes.

Slate microphone

A microphone, built-in or external microphone, on an audio mixer used to notate takes or communicate with sound

team members by the mixer’s user speaking into the microphone. Slate microphones are often routable to buses or

tracks.

Smart Battery

A lithium-ion rechargeable battery with integrated telemetry indicating battery condition, run time and other useful data.

Stereo linking (inputs)

When active for stereo sources such as stereo microphones, linked inputs are hard panned to the left and right bus.

Controls including gain (trim), fader, high pass filter, delay, limiter, mute, and routing are controlled together.

Solo

A control on a mixer to route a channel to headphones while muting all others. Solo and PFL are related controls and

in many consoles are the same. Solo circuits can be exclusive—only one channel is sent to headphones at a time—or

non-exclusive—any number of channels can be sent to the solo circuit and appear in headphones.

SuperSlot™

SuperSlot™ is an electro-mechanical connection protocol, developed by Sound Devices, to simplify the

interconnection of wireless audio transmitters and receivers with audio mixers and cameras. SuperSlot provides,

power, audio, and control signals over a single multi-pin connection. SuperSlot-compatible products will be offered by

multiple manufacturers, including wireless system manufacturers, camera manufacturers, and audio mixer

manufacturers.

TA-type connector (TA3, TA4,TA5)

Miniature XLR-type, locking connectors. TA3 connectors are used by Sound Devices for various inputs, outputs, and

as balanced and unbalanced connections. TA4 connectors are used by Sound Devices for DC power connections to

the 833 mixer-recorder. TA4 is also used for audio connections from lavalier microphones to some wireless

transmitters. TA5 connectors are used for the 833 headset input. TA6 connectors are presently not used by Sound

Devices though they are used for audio connections by other manufacturers.

Take

A recorded take is an individual recorded file (or files when recording monophonic WAV files) generated by a recorder.

Take numbers are auto-incrementing. Take numbers are added to the end of the file name.

Take list

833 User Guide Glossary

122

Separate from a file list, a take list consolidates related files such as a group of monophonic WAV files generated by a

single take and presents them as a single take.

Test tone

See tone oscillator.

Timecode

A numerical clock value expressed in hours:minutes:seconds:frames, i.e. 04:59:39:05, used to synchronize cameras,

video decks, and audio recorders. Timecode requires clocks on devices to be synchronized, either through a wired or

wireless connection between devices, or through a process called “jam sync” where each device, which requires a

high-precision clock, runs independently after their clocks are synchronized.

Timecode mode

Sound Devices recorders offer multiple timecode modes. Different modes correspond to different timecode workflows.

Common modes available in Sound Devices recorders include:

record run - timecode advances only when recording is engaged

free run - timecode run continuously, typically with the start of production being at 0 hour

24 hour - similar to free run except the start time corresponds to time-of-day

ext TC - the recorder applies the value of an external timecode source.

Tone oscillator

A sound generator producing a sine wave tone at a given frequency at a given output level. With its known output level

tone oscillators are helpful to set gain structure between audio equipment.

Track

A single recorded audio signal. Common recorded tracks are the main left/right master audio bus and isolated (iso)

channel recordings. Iso tracks are typically identified by the channel of the same number, e.g. channel 1 is sent to

track 1, channel 2 is sent to track 2, etc.

Track arm

Tracks that are active and ready for recording are said to be “armed”. When recording begins all armed tracks begin

recording. Depending on the production is may be advantageous to arm and disarm tracks, especially to disarm

unused tracks.

Track name

Individual tracks of a multi-track recording can be named to indicate microphone type or character name.

Trim

Also defined in mixers as “gain”, the trim adjustment is the first stage of gain of a microphone or line level input. Typical

microphone trim values range from 10 dB to 50 dB, depending on microphone sensitivity and volume of the sound

source.

User bits

Static, numeric data that is available as part of a timecode signal. User bits are often used to indicate the date of a file.

User bits are four sets of two-digit hexadecimal numbers from 00 to ff.

WAV File

A universal, well-supported file type for sound file recordings. WAV files can contain one or more (up to 65,535) tracks

of PCM audio data at any sampling rate and bit depth. A standard WAV file is limited to a maximum file size of 4 GB.

Sound Devices uses the .WAV extension for recorded files, including for files with Broadcast WAV metadata.

WAV RF64

833 User Guide Glossary

123

An extension of the WAV file type that supports file sizes larger than 4 GB. When recording high track count, high

sampling rate polyphonic WAV files, the 4 GB size limitation of WAV can be reached quickly. RF64 files larger than 4

GB require recording to a volume type than can support file sizes larger than 4 GB.

Word clock

A reference signal used to synchronize the sampling rate of multiple digital devices.

XLR female

Industry-standard 3-pin locking audio connector for microphone and line-level sources. Predominantly used as an

input. Also shown as XLR-F.

XLR male
