● The IMT band (1518-1525 MHz)

Please see https://www.sounddevices.com/available-frequencies/ for further detailed information on which frequency

ranges are available for each country and also Frequency Authorization for details on using restricted frequencies.

1.3 NexLink Wireless Transmitter Control

NexLink is a proprietary 2.4 GHz bidirectional wireless data link technology that allows multiple Astral Mini transmitters

to be controlled, monitored, and timecode synced from an Astral Receiver over long distances. NexLink is designed to

offer robust and reliable control over distances far exceeding that of the wireless audio transmission, even in the

presence of Wi-Fi, Bluetooth, and other 2.4 GHz interference. Astral Receivers can pair with up to 64 NexLinked

transmitters at a time.

1.4 GainForward

The Astral Mini transmitter supports GainForward, a technology that eliminates the need to adjust audio gain at the

wireless transmitter. Audio levels from the transmitter are controlled either directly at the mixer’s trim control or at the

wireless receiver. If the source is too soft or too loud, adjust the transmitter’s audio level with a downstream mixer’s

digital trim gain control. There is absolutely no noise penalty when the audio path remains 100% digital (i.e., Astral

transmitter -> Astral receiver, Astral receiver digital audio output -> mixer digital audio input). Read more about

Astral Mini User Guide Tuning the Astral Mini and Receiver

Chapter 5: Tuning the Astral Mini and Receiver

RF signals transmitted by the Astral Mini transmitter are received by Astral Receivers, the Astral-RX2 and Audio Ltd

A10-RX. Set the same modulation and frequency on the transmitter and receiver. See the Astral ARX32, Astral

ARX16, Astral ARX8, Astral-RX2 and A10-RX User Guides for more details.

Frequency

The Astral Mini transmits on frequencies ranging from 470 MHz – 1525 MHz. The frequencies available are

determined by geographic location and whether you have entered a unique license code issued by Sound Devices to

unlock the use of restricted frequencies.

Because the Astral digital RF transmission is inherently immune to intermodulation, multiple Astral Digital Wireless

transmitters can be used simultaneously on nearby adjacent frequencies without worry of intermodulation interference.

Systems can be used together when separated by at least 400 kHz. When operating in the 902-928 MHz Band, it is

recommended to separate channel frequencies by at least 1 MHz.

Set the Astral Mini’s transmit frequency via the Astral Remote App or Astral Receiver via NexLink.

Ensure an antenna with a length specific to the frequency in use is attached to the SMA connector. Using the wrong

length of antenna reduces RF range. See the Antenna Guide for more information.

Modulation

The Astral Mini offers three types of modulation, Long Range, Standard, and T&M. Long Range modulation has better

sensitivity resulting in more robust performance in challenging RF environments. Standard modulation has lower

latency (2ms versus the 3.9ms of Long Range). T&M modulation has been specifically optimized for the flattest

frequency and phase response possible for test and measurement applications. The Modulation setting must match

between the Astral Mini and Astral receivers, for the transmitted signal to be received.

RF Power

RF power is the strength of the transmitting signal. The Astral Mini offers the following RF power settings:

● Low - 2 mW

● Normal - 10 mW

● High - 20 mW

● *Extra High - 40 mW. *This RF Power setting must be enabled from the Astral Remote app or from an Astral

Receiver via NexLink.

Set the Astral Mini’s RF Power via the Astral Remote App or Astral Receiver.

RF Power settings are based on the selected Country of the device running Astral Remote as some legal restrictions

may apply.

In situations where the transmitter is relatively close to the receiver, the Low - 2 mW setting offers good range and best

battery life. For most common wireless microphone applications, the Normal - 10 mW setting provides excellent range.

In situations where body absorption may be an issue or extended range is required, the High - 20 mW setting can be

helpful. If significant body absorption is unavoidable or maximum range is required, the Extra High - 40 mW setting can

be enabled via the Settings menu. Please be aware that the Extra High - 40 mW RF Power setting can reduce battery

life by over 20%.

Tip: Use Long Range Modulation to increase RF range prior to increasing the RF Power setting.

Astral Mini User Guide Audio Levels - GainForward

Chapter 6: Audio Levels - GainForward

The Astral Mini transmitter introduces GainForward, a new feature that eliminates the need to adjust microphone

preamplifier gain at the wireless transmitter. Audio levels from the transmitter are controlled either directly at the

mixer’s trim control or at the wireless receiver. If the talent speaks too softly or emotes too loudly after being “wired”

with the transmitter, simply adjust the transmitter gain with the mixer’s gain trim. Read more about GainForward at:

https://www.sounddevices.com/gainforward-explained/

Adjusting Audio of the Astral Mini Signal from the Astral-RX2 and A10-RX Receiver

From the Astral-RX2 or A10-RX home screen, press the channel’s arrow button twice to enter the Input menu. From

the Input menu, press the middle button to select a sub-menu to adjust gain, low cut, or limiter of the incoming Astral

Mini transmitted signal.

Gain is adjustable from 0 to 60 dB. Low cut can be set to Off, 40 Hz, 60 Hz, 80 Hz, 100 Hz, or 200 Hz. Limiter can be

turned on or off. The information menu displays the status of the tuned Astral Mini. See the Astral-RX2 or A10-RX User

Guides for more details.

Adjusting Audio of the Astral Mini Signal from Astral Receivers

See the Astral ARX32, Astral ARX16 and Astral ARX8 User Guides for details.

Adjusting Audio of the Astral Mini Signal from the 8-Series or 688

When the Astral-RX2 or A10-RX receiving Astral Mini signal is slotted into the SL-2 or SL-6, the Astral-RX2 or A10-RX

Input menu settings are bypassed and all gain, low cut, and limiter activity are performed and controlled by the 688,

833, 888, or Scorpio. This is also the case when using an Astral ARX16 docked to an 8-Series. See the Mixer-

Recorder User Guides for more information.

Chapter 7: Recording WAV Files

The Astral Mini records 32-bit float Broadcast WAV (under 4 GB) or RF64 WAV (over 4 GB) files at 48 kHz sampling

rates to an internal SSD. 32-bit float files are recorded such that gain decisions can be made after recording. Because

of the Astral Mini’s high dynamic range, audio levels are never too high or too low. Learn more about 32-bit float at:

https://www.sounddevices.com/astral-mini-32-bit-float-recording/

The Astral Mini must be set to REC+RF or REC Only Mode.

Astral Mini recording can be initiated in several ways including from the:

● Astral Remote App

● Astral Receivers via NexLink

The file name format of recorded files is “transmitter name-YYMMDDHHMMSS.WAV”.

For example, if the Astral Mini name has been changed to “Barney” and a recording is created on July 10, 2021 at

09:30 (24 hour format), the resulting file is named Barney-210710093000.WAV. All files are recorded at the root of the

internal SSD.

About recording formats:

● The Astral Mini records 1-ch monophonic 32-Bit float / 48 kHz wav files.

● The internal SSD is formatted as ExFAT which can record file sizes > 4 GB. Recordings that exceed 4 GB are

automatically converted from standard broadcast wav to RF64 wav format.

Astral Mini User Guide Jamming Timecode

Chapter 8: Jamming Timecode

The Astral Mini accepts timecode from external LTC sources. The timecode can also be wirelessly ‘jammed’ into the

Astral Mini’s internal timecode generator via NexLink from an Astral Receiver. The timecode value and frame rate are

taken from incoming LTC. If timecode has not been jammed, the Astral Mini starts rolling timecode from 00:00:00:00

when it is powered on.

Jammed timecode values are held for up to four hours after powering off, and up to one hour after the battery has

been removed. This allows for time to swap batteries without having to re-jam timecode.

To jam timecode, connect a valid LTC source using one of the optional accessories, Sound Devices XL-TC-USBC-

LEMO or XL-TC-USBC-BNC, to the Astral Mini USB-C port. Timecode is automatically jammed once a valid LTC

source is connected. After a successful timecode jam, the Audio/LTC LED flashes blue on the 00-frame crossing.

Timecode is output from the USB-C using the Sound Devices XL-TC-USBC-LEMO, so that you can verify the Astral

Mini timecode is in sync with the LTC source. The Audio/LTC LED stops flashing blue when USB-C is disconnected.

For more information about the Astral Mini timecode accessory cables visit:

https://www.sounddevices.com/product/xl-tc-usbc-bnc/

https://www.sounddevices.com/product/xl-tc-usbc-lemo/

Astral Mini can also jam timecode from 8-Series Mixer-Recorders using a standard USB-C to USB-A cable. Connect

the Astral Mini to the 8-Series USB-A port. Enter the 8-Series Menu>Timecode/Sync>Jam Astral Transmitter then

select Jam. The 8-Series Jam Astral Transmitter menu displays the current timecode frame rate and values for the 8-

Series and Astral Mini and displays the difference between the two units.

When the Astral Mini is powered off, the Audio/LTC LED and the Charge & Timecode LED flash blue on the 00-frame

crossing to indicate timecode is being held.

The Astral Mini can also receive and jam timecode while connected to the optional PowerStation-8M via USB-C. See

PowerStation-8M for more details.

used, all eight charging bay LEDs illuminate. If a USB adapter is used which does not supply sufficient power, then

only three of the charging bay LEDs will illuminate.

The PowerStation-8M only charges Sony NP-BX1 batteries within an Astral Mini. AAA battery charging is not

supported. Inserting Astral Minis with AAA batteries into the charging bay will not damage anything, but the unit will not

charge.

Insert the Astral Mini into an enabled charging bay of the PowerStation-8M. The Astral Mini slides into a charging bay

with the antenna-side first, the antenna may be left attached. Sound Devices recommends disconnecting lavalier

microphones before inserting the Astral Mini into the charging bay.

Charging status is indicated by the Astral Remote application and the Astral Mini bottom panel Charge LED.

● Solid Green = Charging complete

● Off = Not charging

Astral Mini transmitters are powered off when inserted into a charging bay. The Astral Mini powers on when removed

from the charging bay if ‘Power On When Removed from PowerStation-8M’ is active.

Bottom Panel 1/4”-20 Mounting Point (not pictured)

The PowerStation-8M offers a 1/4”-20 mounting point on the bottom panel for securely attaching to a rack shelf, such

as the Pyle 1U Server Rack Shelf Mount Tray PLRSTN14U.

https://pyleusa.com/products/plrstn14u

Powering the PowerStation-8M

The PowerStation-8M is powered via 12 VDC TA-4 connector or USB-PD power supply. The supplied 36 W USB-PD

power supply supports full operation. Make certain third-party USB-C power supplies offer 36 W or higher to charge all

eight Astral Mini transmitters at a time. Make certain any external supply connected to the TA-4 connector supplies at

least 36 W.

Distributing Timecode to Astral Mini Transmitters

The PowerStation-8M is equipped with a Timecode input on BNC. Connecting a valid LTC timecode source to the

PowerStation-8M jams the frame rate and timecode value to all inserted Astral Mini transmitters. The Astral Mini

bottom panel Timecode LED flashes blue on the 00-frame following a successful jam.

Transferring Astral Mini Files via PowerStation-8M

The File Transfer USB-C connector is used to connect Astral Mini transmitters slotted into the PowerStation-8M to a

computer as mass storage devices. Each connected Astral Mini transmitter will appear as its own mass storage device

when the

PowerStation-8M is connected to a computer. The PowerStation-8M USB-C connector is SuperSpeed USB (5 Gb/s)

offering maximum transfer speeds when all eight slots are filled.

Astral Mini User Guide Frequency Authorization

Chapter 15: Frequency Authorization

The wireless system operator needs to be aware of local regulations and comply with all applicable laws regarding

operation of wireless devices.

Frequency Authorizations allow the unlocking of restricted frequencies that require proof of a valid license before they

can be used. Once a license has been granted, please contact Sound Devices (RF_Request@SoundDevices.com) to

obtain the necessary authorization. An Authorization ID and License Code will be generated by Sound Devices based

on the license provided. The Authorization ID or License Code can be entered into the Astral Remote App and then

synchronized with an Astral ARX8, Astral ARX16, or Astral ARX32 receiver and its paired Astral transmitters.

An example of a frequency band requiring an unlock code in the United States is 1435-1525 MHz. Program Making

and Special Events (PMSE) wireless operators typically call 1435-1525 MHz the "AFTRCC band". AFTRCC stands for

Aerospace and Flight Test Band Coordinating Council. This organization coordinates several frequency bands for use

by air and spacecraft in the United States. This includes 1435-1525 MHz.

Per the United States Federal Communications Commission (FCC) rules, wireless microphones are allowed as

secondary users in the 1435-1525 MHz AFTRCC band. This is detailed in the FCC Part 74 rules:

https://www.ecfr.gov/current/title-47/chapter-I/subchapter-C/part-74

One section of the Part 74 rules that's of particular interest to operators seeking an AFTRCC band license is 74.803(d):

https://www.ecfr.gov/current/title-47/chapter-I/subchapter-C/part-74#p-74.803(d)

Generally speaking, a wireless operator needs to show they've used all other available spectrum before the AFTRCC

will consider a license request in the 1435-1525 MHz range. If granted, the license is normally assigned for a specific

location and a specific time range.

Sound Devices encourages all wireless operators to obtain a Part 74 license, and specifically to make sure applicable

parts of the 600 MHz and 950 MHz range are included with their license application. This can help show an operator is

aware of the available spectrum and is utilizing it responsibly.

More information on Part 74 licensing can be found here: https://www.local695.com/fcc-licensing/

Astral Mini User Guide Antenna Guide

Chapter 16: Antenna Guide

The Astral Mini ships with an antenna set with three antennas (1 straight 470-548 MHz, 1 straight 548-638 MHz, 1

straight uncut, set of antenna caps).

Sound Devices offers additional pre-cut and uncut antennas as available options.

Attach antennas with a length specific to the frequency in use. Using the wrong length of antenna reduces RF range.

Cutting Antennas to Length

Uncut antennas need to be cut to the length specific to the frequency for intended use.

1. Determine the frequency range intended for the uncut antenna using the Antenna Length chart.

2. Measure the antenna for the cut point. Measurements should begin from the bottom of the SMA connector.

3. Using a pair of cutters, cut the quarter-wave antenna at the specified cut point.

4. Position the antenna cap onto the cut-end of the antenna and push the cap firmly onto the antenna.

Tip: Use an Astral ARX receiver’s built-in Antenna Length Tool to assist in cutting antennas to the correct length.
