Overview
The A10-RX two-channel Advanced Dual Diversity receiver is a portable, all-digital wireless
receiver for the A10 system. It is designed to work with one or two A10-TX transmitters. It offers
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 efciency.
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
• The A10-RX receiver when tted into the A-15PIN cradle enables compatibility with
Sony’s proprietary slot for wireless receivers. This collaboration between Sony and Sound
Devices allows the A10-RX receiver to pass two channel digital audio internally on the Sony
camcorder negating the need for any external cables.

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 off 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).
ªShortcut: To power off RX1, simultaneously hold the Left and Centre Menu buttons down for
two seconds. To power off RX2, simultaneously hold both Right and Centre Menu buttons
down for two seconds. Repeat to turn the individual channels back on. If both RX channels
are powered off, the A10-RX will enter standby mode. Press the Centre button to turn both
channels of the RX back on simultaneously.
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.
ªThe 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.

RF Signal Indicator LEDs
The RF Signal LEDs offer an at-a-glance indication of RF performance. The LEDs to the left of
the display indicate channel 1 activity, while the LEDs to the right indicate channel 2 activity.
Each channel has one green LED and one red LED.
• Green LED only - illuminates solid green with good RF reception. It starts to icker green
as the received RF signal quality deteriorates.
• Red LED only - received RF signal quality is deteriorating.
• Both green and red LEDs are ON when RF signal is overloading/too strong..
• Both green and red LEDs are OFF at the fringe of reception.
ªThe 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.
RF Overload Indication.
When RF signal is overloaded, the A10-RX’s green and red LED turns on and the screen
displays “RF Overload”. If you see this indication the RF signal is too strong. Correct the
situation by reducing RF power on the transmitter, increasing the distance between Tx and Rx, or
applying attenuation to the antenna system in use.

Basic Operation
Frequency Selection
The A10 Digital Wireless System operates in the UHF frequency band from 470 to 694 MHz.
The A10-RX can tune across the entire range of the system.
Because the A10 digital RF transmission is inherently immune to intermodulation multiple A10
Digital Wireless systems 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.
Manually Setting Channel, Sub Channel, Frequency
To simplify frequency selection, frequencies are divided into channels and sub channels. The
specic frequencies corresponding to channels and sub channels depends on the setting of the
TV Channel Mapping (Main > Settings > TV Ch Map). Three options are available, 6, 7, and 8
MHz spacing, X, Y, and Z respectively. These three settings generally correspond to three main
geographic regions, the Americas, Australia/New Zealand, and Europe, respectively. For more
information, see Channel Assignments by Region.
• Channel - corresponds to broadcast television channels used in a geographic region.
Depending on the selected channel mapping, channels cover 6, 7, or 8 MHz.
• 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.
• Frequency - specic frequencies within the receivers tuning range can be selected in 25
kHz increments. When a selected frequency does not correspond with a channel/sub channel
mapping, an asterisk character (*) is shown in the display adjacent to channel/sub channel
assignment below the frequency shown.
To change TV channels:
1. Use the Left button to highlight the TV Channel.
2. Press the Centre Menu to select the TV channel.
3. Select the sub channel until the desired sub-channel is selected.
ªRemember, for a given channel / sub channel, the actual frequency will change depending on
the TV Channel Mapping setting.
See the Frequency Tables in this guide for a complete list of frequencies corresponding to the
channel and sub channel selections.
Frequency Scanning
The frequency scanning tool uses the radios in the A10-RX to measure and display RF activity
within the system’s tuning range. This allows a user to nd frequencies with low RF activity
suitable for system operation. The scan tool operates over the full 224 MHz bandwidth of the
receiver. Enter the scanner from the Selection Menu Main > Scan.
ªAudio from channel 1 and channel 2 is muted when the scan tool is active.
To initiate a scan, press the >> button. The scan will start, working from lower frequencies
to higher frequencies. The cursor can be seen to move along the screen denoting the current
position of the scan. The scan can be stopped by pressing the Left button.
Selecting the > button allows the user to manually step through in 400 kHz steps at a time.
Selecting the << button allows the user to automatically scan backwards, and similarly selecting
the < button allows the user to manually step lower in frequency in 400 kHz steps.

A10-RX User Guide
Partial Scanning, 25 MHz Increments
In partial scanning mode the receiver scans a 25 MHz range. This partial scan improves the
resolution of the scan over a full scan. The ten partial scans cover the following ranges:
1 - 470-495 MHz
2 - 492-517 MHz
3 - 515-540 MHz
4 - 537-562 MHz
5 - 559-584 MHz
6 - 581-606 MHz
7 - 603-628 MHz
8 - 626-651 MHz
9 - 648-673 MHz
10 - 669-694 MHz
Full Scan, 224 MHz
The full receiver bandwidth of 224 MHz can also be scanned.
User Group Scan
When user groups are in use, an additional option called UG is available in the Scan menu.
Selecting this will only scan frequencies in the loaded user group.
Audio Output and Control
The A10-RX outputs either analogue line level or AES3 digital audio. This global setting applies
to both channel outputs.
Analogue Output
When set to analogue in the Selection Menu the A10-RX outputs low-impedance, balanced
line level audio. It is designed to connect to balanced or unbalanced line level inputs. To un-
balance the output, oat pin-3.
AES Digital Output
When set to AES output in the Selection Menu the A10-RX outputs two-channel AES3 at 24-
bit, 44.1 kHz. Channel 1 output appears at AES left, channel 2 appears at AES right.
With the A10-RX-XLR the channel 1 XLR connector is used for AES3 output. The channel 2
XLR connector is not active when set to AES output.
Antennae
The SMA antenna connector is used to mount the included 1/4-wave whip antenna. For specialty
applications external, high-gain receiving antennae can be attached to the SMA connector.
ªEnsure that the antennae used are built for the correct frequency.
For best operation and reception power with the included 1/4-wave antenna, keep it in the free
eld, away from metal objects or transmitting devices.
User Groups
The User Groups feature allows for easy, intuitive naming of specic frequencies for each A10
transmitter used on set, and grouped together for faster tuning. The operator of an A10 receiver
may then easily switch between transmitters by choosing alphanumeric names, such as “Jack”
and “Jill”, instead of having to remember and manually tune to different, specic numerical
frequencies.
For instance, a producer or director may want to monitor several different actors’ wireless
transmitters. Rather than having to keep a list of all of their frequencies, each transmitter may be

- 13 -
A10-RX User Guide
pre-assigned a frequency and given an actor’s name. Then only those pre-assigned frequencies
that have been named will be available as possible options for tuning.
User groups are created in Mic2Wav—a utility application available as a free download from the
Audio Ltd. website to Mac or Windows-based computers—and then uploaded, as ALUG les, to
A10 transmitters and receivers.
To create a new user group:
1. Open Mic2Wav on your computer.
2. Do one of the following:
• On a Mac, select User Group File > New.
• On a PC, select File > User Groups > Create a new le.
3. Name the new group.
4. Select a range of frequencies via the Band
drop-down list. Options include A, B, C, D and
Any. This will automatically restrict users in
the group to the frequencies within that band.
Selecting Any will make frequencies within all
bands available for assignment to users in the
group.
ªAll A10-TX will have the available bands
listed on the printed label inside the battery compartment door as well as displaying the
frequencies capable of being generated by the transmitter in Menu > System > Info.
5. Select OK. The User Group Editor screen appears with elds for the rst user (U1) available.
6. Enter a Name and Frequency for U1 in the elds provided. The A10-TX transmitter’s serial
number is optional.
Entry of ineligible frequencies (or characters) will cause the text in the eld to appear red.
Mic2Wav automatically lls in .000 as the subchannel variable for frequencies entered
as a whole number. Mic2Wav automatically follows the best-practice method of spacing
adjacent transmitters by at least one subchannel, preventing possible interference from other
transmitters.
7. Click Add (on a PC) —or the Plus (+) button on a Mac— to add the user to the group. This
also adds a new line for the next user (U2, U3, etc). Each user in a group can be given a name
and frequency, which after upload, will then be displayed on A10 receivers and transmitters.
Each group can have up to 32 users.

- 14 -
