Overview
The A10-RX two-channel Advanced Dual Diversity receiver is a portable, all-digital wireless re-
ceiver for the A10 system. It is designed to work with one or two A10-TX transmitters. It oers
224 MHz switching bandwidth and precision RF tracking lters in a lightweight, robust package.
Two models are available, the A10-RX-SL for slot-in connection and the A10-RX-XLR for
stand-alone operation with hardwired power and audio connections.
The A10 systems ultra-low 2 mS end-to-end delay and superb digital audio assures performance
that is indistinguishable from a hard-wired cable. The A10 system allows the user to operate up
to 20 channels in an 8 MHz TV channel, maximising spectrum eciency.
Key Features
Some key features of the A10-RX are:
• Two-channel, wideband receiver usable over the whole A10 system range
• Advanced Digital Diversity topology uses two complete RF receivers for each of the two
channels, four RF receivers total
• Easy and fast menu control
• Available in both slot (Uni-/SuperSlot) with the A10-RX-SL or stand-alone cabled version
with the A10-RX-XLR
• Analogue line-level or AES3 digital audio output

System Quickstart
The A10 Digital Wireless System is easy to use. Follow the steps below for basic setup and operation.
At the Receiver
1. Fit the included straight and right-angled antennae to the A10-RX receiver.
2. Connect the receiver to a power source. It will immediately power on.
3. Using the scanning tool in the Selection menu nd an available open frequency. If multiple
wireless systems are in use, make certain to keep frequencies least 400 kHz apart.
4. Connect the audio output from channel 1, channel 2, or both to an audio input on a mixer,
recorder, camera, or PA system.
5. Ensure that the receiver audio output type and level are set based on the input type.
At the Transmitter
1. Attach the straight antenna to the A10-TX.
2. Attach an audio source to the 3-pin LEMO input connector.
3. Insert AA batteries into the A10-TX battery compartment and power on the unit with the red
On/O button.
4. Set the audio input type to set to match the connected input.
5. Set the transmitting frequency on the A10-TX match the frequency set on the A10-RX re-
ceiver channel.
6. Adjust the audio gain according to your environment and source, taking care not to overload
the signal. This is indicated by a red LED.
At the Receiver
1. Conrm that the Channel Power LED is solid blue.
2. Conrm that the RF Status LEDs and display indicate good RF strength.
3. Conrm that the audio level at the receiver corresponds to the audio connected to the
A10-TX input.
4. The system is now ready for use.

Powering
The A10-RX-SL receives power over its D-sub connector. The A10-RX-XLR receives power
from its 4-pin Hirose female connector. The male Hirose connector is a power loop through.
When DC power is present, either at the D-sub connector or the Hirose 4-pin, the A10-RX is
powered. There are no additional power switches.
Channel Powering
Each of the two channels of the A10-RX can be powered on or o individually. When a channel
is powered down that portion of the A10-RX no longer draws power. If the A10-RX is going to
be used for a single wireless channel, best practice is to power down the unused channel. Channel powering is controlled in the Selection Menu (Main > System > Power).
Channel Power LEDs
The A10-RX has blue Channel Power LEDs for each of its two channels. When rst powering
the A10-RX without transmitters present, the LEDs illuminate indicating the receiver channel is
powered.
The receiver channel will connect, or pair, to an A10-TX transmitter that is powered on and set
to the receiver frequency. The Channel Power LED then shows the battery status of its associated
transmitter.
• Solid Blue - a solid blue LED indicates that the transmitter battery is in good condition.
• Flashing Blue - a ashing blue LED indicates when the transmitter battery level is low or
depleted.
When a paired transmitter is powered down, the blue LED continues to show the last condition
of the transmitter battery. If the transmitter is powered back on, or a new transmitter is activated
on the channel, that transmitter pairs with the receiver and its transmitter battery condition is
shown with the blue LED.
ª The LEDs change assignment based on the orientation of the display. Channel 1 is always
shown left of the display and channel 2 is always on the right.
