Studio Technologies Model 22 IFB Plus Series Access Station

The Studio Technologies Model 22 IFB Plus Series Access Station is created to work with Model 2A Central Controllers. Featuring 2-channel IFB remote panel, and backlit pushbutton switches, Model 22 requires no external power source, supports mic and line inputs, and delivers excellent audio quality.

The Studio Technologies Model 22 IFB Plus Series 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. The Studio Technologies Model 22s are typically installed at positions convenient to producers, directors, or other personnel who need to cue on-air talent. Up to four Studio Tech Model 22 units can be connected to, and powered by, a Model 2A Central Controller.

The Studio Technologies Model 22 consists of a metal chassis containing two lighted pushbutton switches, microphone and line inputs, and supporting audio, status, and control circuitry. An external interrupt audio source is required. This can be in the form of a microphone or line-level signal. A microphone input is provided for connection to an electret gooseneck microphone. The Studio Technologies Model 11A Gooseneck Microphone, an option available from Studio Technologies, is directly compatible. The transformer-coupled line input allows various pieces of communications equipment to serve as the interrupt audio source. This can be used to interface with intercom systems from companies such as RTS® and Clear-Com®, typically utilizing their "hot mic out" signals. A configuration switch allows the Studio Technologies Model 22 interrupt activity to mute the monitor amplifier output on the associated Model 2A Central Controller.

The optional Model 25A 19-Inch Rack Adapter allows the Studio Technologies Model 22 to be mounted in one space of a standard 19-inch rack enclosure. Alternately, the Studio Tech Model 22, along with an optional Model 28A Panel Adapter, can be flush mounted in an opening provided in a custom-fabricated enclosure or cabinet surface. The Studio Tech Model 22 interfaces with the Model 2A Central Controller using a 9-conductor interface cable. Power for the Studio Tech Model 22 is provided by the connected Model 2A Central Controller.
