Studio Technologies Model 72 Level Meter / Interface

Level Meter / Interface The Model 72 Level Meter/Interface is a compact, portable device that plugs directly into an IFB or intercom circuit and provides two useful functions: audio level meters and line-level audio outputs. IFB (interruptible foldback) circuits are used in broadcast applications, providing one or two channels of talent cue audio. Intercom circuits are used by production personnel, supplying one or two channels of "party-line" communications. Two 5-segment LED meters allow direct observation of the audio signal levels present on the connected IFB or intercom circuit. The display range is optimized for the signal levels found on typical "wet" (DC with audio) IFB and intercom circuits, rather than traditional "VU" scaling. Two audio outputs provide transformer-coupled "dry" signals, one output associated with each IFB or intercom channel. These pro-audio-quality outputs are useful for a variety of production and testing applications. For example, the outputs can serve as
