Spare Master panel that includes the Caller Input, Control Room monitor, Studio monitor, and Meters sections.

• Caller Input: The caller section is used for the telephone call-in talk segments, and controls the audio for the caller. The caller signal enters the console from your station hybrid. The caller feed can be either or both of the to Program buses. the caller feed will never contain the caller's own voice. A recessed rear panel trimpot adjusts the caller output level.
• Program Assign: Output switches assign the caller to any combination of the console's two Program outputs (PGM1 and PGM2), and permit live talk-ins. Pressing either of the two program switches causes the caller's audio to be included in the output mix for that bus, at a level dependent on the FADER setting, as long as the caller section is ON.
• CUE Button: The CUE button allows interviewing the caller prior to airing by including the caller's voice in the console's cue bus, where it may be heard on the meterbridge mounted cue speaker.
• TB Button: When the TB switch is pressed (it is momentary action), the microphone (MIC 1) will interrupt the regular caller signal, thus allowing the DJ to talk to the caller prior to airing.
• Fader: The long-throw fader sets the caller's signal level.
• ON Button: The ON button determines if the phone channel is ON or OFF. If the phone channel is OFF, caller signal will not be present in any main bus output, regardless of the status of the PROGRAM ASSIGN buttons or the position of the fader. If the phone channel is OFF its signal will still be present in the cue output if it has been assigned to cue.
