Clear-Com RM-702 2-Ch Remote Intercom Station

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
