Overview
The A10 Digital Wireless System meets the demanding requirements of the professional sound
community engaged in lm and television production. It oers superb audio and RF performance.
The digital RF transmission of the A10 system allows the user to operate up to 20 channels in
an 8 MHz TV channel, maximising spectrum eciency without compromising on range, audio
quality or latency.
The A10-TX-US is the U.S.-only version of the transmitter. It incorporates Audio Ltd’s proprietary digital modulation scheme whilst maintaining the high audio quality that Audio Ltd has
become renowned for, and with extremely low end-to-end latency of 2 mS.
The A10-TX-US has an intuitive menu system allowing the user to become familiar with settings
within a few minutes of turning it on.
Key Features
• Low-noise, studio-grade balanced input for microphones and line level signals with analogue
limiter and phantom power.
• Fully digital RF transmission
• Remote controllable over Bluetooth® using the A10-TX-US Remote app for Android and iOS.

Basic Operation
Frequency Selection
The A10 Digital Wireless System available in the operates in the UHF frequency band from 470
to 608 MHz. There are two models of the A10-TX-US transmitter to cover this frequency range.
Multiple A10 Digital Wireless systems can be used simultaneously on nearby adjacent frequencies without worry of intermodulation interference since the A10 Digital Wireless System and its
digital RF transmission is inherently immune to intermodulation. Systems can be used together
when separated by at least 400 kHz. Use the scan tool on the A10-RX receiver to search for
available frequencies.
ª When using A10 Digital Wireless systems in conjunction with analogue RF systems, an
intermodulation plan needs to be addressed for analogue receivers.
Channel, Sub Channel, Frequency
To simplify frequency selection, frequencies are divided into channels and sub channels.
• Channel - corresponds to broadcast television channels used in geographic region.
• Sub Channel - channels are divided in 400 kHz increments called sub channels to speed up
frequency selection. The number of sub channels depends on the channel mapping selected.
• Tune - specic frequencies within the transmitter’s tuning range can be selected in 25 kHz
increments.
To change TV channels, use the Left button to highlight the TV
Channel. Press the centre Menu button to select the TV channel.
Select the sub channel until the desired sub-channel is selected.

A10-TX-US User Guide A10-TX-US User Guide
See the Frequency Tables in this guide for a complete list of frequencies corresponding to the
channel and sub channel selections.
Audio Input and Control
The A10-TX-US input accepts a wide range of audio input types, including lavalier micro-
phones, balanced microphones, and balanced and unbalanced line level signals. 12 V and 48 V
phantom power is available for balanced microphones. The Selection Menu oers options for
audio level control, input type, limiters, and low cut lter.
Lavalier Microphones
Unbalanced lavalier microphones wired in two-wire mode, are directly compatible with the
A10-TX-US input. When connected, the A10-TX-US auto-detects the presence of a lav microphone.
Balanced Microphones with Phantom
Balanced microphones, including phantom powered shotgun microphones, can be connected
to the A10-TX-US. 12 V and 48 V phantom power are available for microphones requiring
it. For microphones that can properly operate on 12 V phantom, such as the Schoeps CMIT,
select 12 V phantom to signicantly increase battery runtime.
Line-Level Sources
Wireless systems are often used as “camera hop” systems. For most camera hop applications
the output of a eld mixer is connected to a wireless transmitter. The wireless receiver output
is connected to the camera input. The line level input selection simplies using the A10 System as a camera hop. Select Line in the Selection Menu to accept balanced or unbalanced line
level inputs.
Remote Control
The A10-TX can be remotely controlled from an Android or iOS device running the A10-TX
Remote app. The app is available as a free download from the Google Play store and iOS App
store, respectively.
With the A10-TX Remote app, you can:
1 - Change the transmitter’s name; it is set to
the transmitter’s serial number by default.
2 - Monitor Sleep status, Battery status, and
Bluetooth® signal strength
3 - Turn Sleep mode On/O

ª To connect balanced microphone or line level sources to the A10-TX-US a cable wired as
described in the specications or the AC-BALXLR cable is required. This connects the shell
of the LEMO connector to pin-1 of an XLR connector.
Audio Level Control
Input levels are controlled from the Audio Gain option in the Selection Menu. The gain range
available is source-dependent as follows:
• Lav setting: 0 dB to 40 dB, 1 dB increments
• Line setting: -10 to 16 dB, 1 dB increments
• Mic setting (with 20 dB pad): 16 to 40 dB, 1 dB increments
• Mic setting (with no pad): 36 to 60 dB, 1 dB increments
Set input levels so that the limiter is active only on the strongest peaks.
Antennas
The SMA antenna connector is used to mount the included 1/4-wave whip antenna. For specialty
applications external, high-gain transmitting antennas can be attached to the SMA connector.
Make certain to connect only passive antennas to the A10-TX-US.
For best operation and transmission power with the included 1/4-wave antenna keep it in the free
eld. If worn on a body keep the antenna away from direct contact with the wearer’s body. When
multiple wireless systems are in use keep transmitters separated by at least 1/2-wave distance of
the transmitted frequency.
