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. Chan-
nel 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.
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.

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. De-
pending 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.

- 11 -
A10-RX User Guide
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 posi-
tion 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.
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.
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.
