Clear-com PIC-4774 IFB Router

Clear-com PIC-4744 provides four XLR3M analog partyline level audio outputs (IFB channels) and four XLR3F analog line level audio inputs (Program channels). Each IFB channel can select and place one of the four program sources to the output. A front panel variable trim pot is supplied for adjusting the source level to the output. Connections to control stations, typically used for a director to cue talent, are provided for interrupting the source input to the audio output. The PIC-4744 can interrupt the program source with variable attenuation. Each IFB channel carries a composite of three signals: the program audio, the cue audio and the dip or mute control. Multiple PIC-4744 panels can be used together if more than four audio outputs are needed.
