Studio Technologies MODEL-22

While the Model 2 Central Controller can be used completely "stand-alone," the Model 22 Access Station can be used to provide additional IFB origination locations. Model 22s are installed at positions convenient to producers, directors, or others who need to cue talent and related personnel. As many as four Model 22s can be used with each Model 2 Central Controller.

The Model 22 consists of a metal chassis containing two lighted pushbutton switches, microphone and line inputs, and status and control circuitry.

The mic input is configured for the connection of an electret gooseneck microphone. The line input, compatible with balanced and unbalanced signals, allows another piece of communications equipment to provide interrupt audio. This allows direct interfacing with intercom systems from companies such as Telex®/RTS® and Clear-Com®.

Several mounting options are available. One adapter allows the Model 22 to be mounted in a single rack space (as shown). A second adapter is used to install the Model 22 in a table or console opening.
