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.
Selectable one- or two-channel communication
Individual listen volume controls
Momentary/latching talk 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
