Basic Operation
Frequency Selection
The A10 Digital Wireless System operates in the UHF frequency band from 470 to 694 MHz.
There are three models (two in some geographic markets) of the A10-TX 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, Tune
To simplify frequency selection, frequencies are divided into channels and sub channels.
Frequencies corresponding to channels and sub channels depend on the TV Channel Mapping
selected in the Systems menu. 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, USA,
Australia/New Zealand, and Europe, respectively.
• Channel
- corresponds to broadcast television channels used in geographic regions.
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.
