1、C-QUAM AM Stereo Exciter Radio Systems Products AMS-G1 next level solutions Features/Benefits MMMMM The Harris model AMS-G1 uses the latest technology available in C- QUAM AM stereo exciters to provide optimum AM stereo perfor- mance from Harris DX, and Gates line of solid state transmitters. New DX

2、 and Gates transmitters can be purchased with the AMS-G1 as com- plete, ready to broadcast AM stereo transmitters. The versatile AMS-G1 stereo exciter, rather than just being a circuit card buried somewhere in the transmitter, comes self-contained in its own compact rack-mounted cabinet. If you alre

3、ady own a Harris solid state AM transmitter, it is also possible to purchase the AM stereo ex- citer separately for your older transmitter to get optimum AM stereo performance. The outputs of the AMS-G1 connect directly to the exter- nal oscillator TTL level input and audio input of your transmitter

4、. The AMS-G1 accommodates all international requirements for channel spacing and is rear panel selectable 100, 120, 220 or 240 volts AC, 50 or 60 Hz. The Harris AMS-G1 can be used with all DX, Gates and SX transmit- ters. For other model transmitters, please check with sales technical support. C-QUA
