331 (mono) & 332 (stereo) FM Modulators are crystal synthesized and are frequency programmable. The standard frequency range is 88.1-107.9 mHz in .2 mHz steps. Output levels are compatible with cable TV headends for retransmission of local audio signals or programs from our satellite demodulators. |
|
381 (Three function) Tone Decoder detects the presence of 25 and 35 Hz tones in the demodulated audio stream and provides on-second (adjustable) contact closure to control local radio automation equipment for cut-aways and station breaks. The 381 operates on a single mono audio channel. |
383 (Six or Fifteen function) Tone Decoder is similar to the 381 tone decoder, but operates on both channels of a stereo pair. By using both 25 and 35 Hz tones on each of the audio channels, multiple functions can be obtained. Relays are included on board so no other parts need to be ordered.
