Clear-Com RM-702 2-Ch Remote Intercom Station
Single rack-space, two-channel station is powered by the intercom line. Operator can talk and/or listen on either or both channels. Accepts line-level audio program input via DB-15 connector, with both channels programmable for interrupt. Microphone limiting and speaker "dipping" circuit for greater output before feedback.
Features: - Selectable one- or two-channel communication
- Individual listen volume controls
- Momentary/latching talk buttons
- Individual call buttons
- Visual call signaling
- Balanced audio input with program interrupt (IFB)
- "Hot mic" and line-level outputs
- Studio announce output with relay
- Optional plug-in gooseneck microphone
- Wide-range high-output speaker
- One rack space
- LED buttons for talk, call, announce, link, all talk, and microphone on
