M1090
FEATURES
- CVR Adapter that operates a differential summing amplifier for combining microphone, communications, intercom and paging audio into one isolated output to the CVR
- Features three biased MIC inputs, three Bias Disable inputs, three AUX inputs, and transformer coupled output to the CVR
- Transformer coupled output stage can handle wiring runs to CVR as long as 200 feet
