Overview
Studio Technologies Model 22 Access Station
The Model 22 Access Station works in conjunction with a Studio Technologies' Model 2A Central Controller to provide a 2-channel IFB origination ("talk") location. Two pushbutton switches allow direct access to each of the IFB channels. The switches are backlit for visibility in locations with low ambient light conditions. Each switch also provides a "tally" indication, lighting brightly when their associated IFB channel is active. The carefully optimized circuitry is capable of providing "high-fidelity" IFB audio performance. This is unique in the often-ignored yet critical talent cueing function. Model 22s are typically installed at positions convenient to producers, directors, or other personnel who need to cue on-air talent. Up to four Model 22 units can be connected to, and powered by, a Model 2A Central Controller.
