Studio Technologies M24 4-Channel IFB Plus Access Station

The Model 24 Access Station allows broadcast personnel to access four IFB channels associated with two Model 2 units. The unit contains five lighted pushbutton switches, four of which are used to activate and display the status of the IFB channels and one that provides an "all call" function. The Studio Technologies Model 11A Gooseneck Microphone or a line-level audio source can be connected. Up to four Model 24 units can be connected and supported by two Model 2 units. The Model 27A 19-Inch Rack Adapter allows a Model 24 and a Model 11A Gooseneck Microphone to be mounted in a single space of a standard rack enclosure.

The IFB Plus Series is designed for electronic news-gathering (ENG) trucks, satellite news-gathering (SNG) trucks, and small production vehicles. Interruptible foldback (also known as talent cueing) allows reporters and other on-air talent to receive program audio along with audio cues from production personnel, generally directors and producers.
