WHAT IS THE TELEX SOUND

ENHANCEMENT SYSTEM?

Transmitter: The transmitter generates and ampli- fies a RF (Radio Frequency) carrier signal, modu- lates this carrier with the microphone signal, and radiates the modulated RF carrier.

Receiver: The FM VHF receiver is tuned to the fre- quency of the transmitter. The receiver picks up the radiated RF signal from the transmitter through the antenna and converts the RF signal into audio volt- ages for use with an earphone, headphone, button receiver, neckloop, etc. The receiver frequency must be matched to the transmitter frequency.

WHAT FREQUENCY BAND DOES THE TELEX SYSTEM OPERATE IN?

The Telex Systems feature a synthesized transmitter and single channel or synthesized receivers operat- ing in the VHF Band between 72-76 MHz. See Ta- ble 1 for standard frequencies available.

Each transmitter channel can be utilized by any number of receivers in any given area. Up to eight simultaneous systems can be used, and with proper placement of adjacent channels, up to ten systems can be used.
