The PST-170 Belt PackTransmitter may be set to any one of the 17 channels which is displayed on the backlit LCD, and operates on frequencies in the 72-76 MHz band. It is lightweight, battery operated and includes a small lapel microphone for convenient portable use. The PST-170 has two audio input jacks. The Auxiliary input is designed to allow the use of audio devices such as teacher's aids or tape players. The second jack is normally used with a microphone and is located on the top panel. The PST-170 is also compatible with the E.D.R. feature of the SR-400.
The PST-170 Transmitter may be set to any one of 17 channels.
Two Transmitters cannot operate on the same channel unless separated by 300 feet (91 m) or more (which is the average maximum operating range). If two transmitters are operating on the same channel inside this perimeter, the receivers will pick up the FM signal of both transmitters, causing a squealing sound to be heard.
Antenna.
The transmitter uses a flexible wire "trailing" antenna that is permanently attached to comply with FCC Part 15 Rules. Do not cut or lengthen the antenna. Do not coil the antenna and place in your pocket. This is a tuned antenna and modification will shorten the range.
Audio Input.
There are 2 audio input jacks on the transmitter. One is the Auxiliary input designed to allow audio devices such as teachers aids or tape players to be used. The input jack is a 1/8 inch (3.5mm) stereo/mono jack. Typical input level is 100 mV RMS maximum for normal modulation. More than this input will cause the audio to "limit" which may sound unnatural. Reduce the input level, if this should happen, by turning down the input device. The second jack is the microphone input. This jack is located on the top panel "step" of the transmitter. The microphone is supplied with the transmitter but other types can be used as well.
