Telex TT-16 Transmitter

Frequency/Channel Considerations: As with any radio device, interference can occur at
any time. The frequencies offered are shared with other legitimate users. Check the
frequency/channel with the matching receiver to see if any interference is present. If
interference is present, choose a different channel. The severity of interference varies with location
and distance to the interfering station. If the interference is weak on all channels,
this is probably acceptable since your transmitter will cover the interference and is unlikely
to interfere with other users. Multiple Channel Systems require other considerations but
each channel should be checked as above. For best results, locate each transmitter in the
area it is to service, and as far apart as possible.
Transmitter Operation: Turn the Monitor control down (counter-clockwise). Now that you
have checked all of the channels you intend to use, apply power to the transmitter by
pressing the Power Button located on the front panel. The Display Screen should now be on. Select
the RF Channel on the transmitter to match the receiver channel. Turn the program
material on (balance and/or unbalance audio input). Adjust the appropriate Audio Input Level
control until loud program material causes the audio level meter to hit 0 dB. This allows sufficient
“headroom” to prevent peak distortion on loud inputs. Set the High/Low power button to High
position initially.
Audio Monitor: After the audio input levels have been adjusted in the above procedure,
stereo headphones with a ¼ in. plug can be plugged into the Monitor jack. If you wish
to monitor the audio program material, turn up the monitor (volume) control to the
desired level. The monitor control does not affect the transmitted audio level.
System Walk Through: Now that the transmitter is set up, you should be able to hear the program
material on the appropriate receiver. Walk the receiver through the area that it is intended to be
used in. Check for any noise or interference that would cause undesired
operation. Some of the causes of poor performance are listed below.
Poor transmitter location.
Poor receiver location.
Interference.
Local AC Line noise.
RF “Trouble Spots.”
Operating distance beyond system capability.
