Selecting the Channel of Operation 

Referring to Figure 1, use a small flat-blade screwdriver to select the 
channel (frequency) on which the transmitter will operate, by aligning the 
triangle-shaped pointer (not the screwdriver slot) to the number of the 
desired channel. Set the receiver to the matching channel. Channels are as 
follows: 

Channel 1: 907 MHz 
Channel 2: 915 MHz 
Channel 3: 923 MHz 
Any other setting of the channel selector (0, 4, 5, 6, 7, 8, 9) defaults to 
Channel 1. 

 
If two AVT900-3 transmitters are to be used simultaneously in a common 
area (so as to broadcast two different audio & video sources), set one unit 
to Channel 1 and the other unit to Channel 3. It is not advisable to attempt 
to use three units simultaneously. 

Connecting Video and Audio to the AVT900-3 

Following the guidelines below, connect line level audio and video 
sources (outputs from a DVD player, for example) to the corresponding 
line-level input jacks on the transmitter’s rear panel (refer to Figure 2). 
Appropriate shielded cables are supplied with the transmitter for making 
these connections. 

Audio – 

If a microphone is to be used as the audio source, an external 

microphone preamp (not supplied) must be used to raise the microphone’s 
output signal to the required line level.
