Telex IFB-1000 Pocket Listen-Only Beltpack

The IFB-1000 is a single-channel, listen-only monitor beltpack for wired intercom. It carries a monaural audio-receive circuit in a low-profile metal case with a belt clip, giving a director, camera operator, or on-air talent a clean feed of cues without a talk path back into the line. A recessed volume control and a power-on LED are the only controls to worry about.

A 3-pin XLR connector taps the party line and supplies all the power the pack needs, and a 1/4-inch phone jack takes an earphone or a wide-response earset such as the EMV-2. The pack runs in Audiocom balanced or RTS and Clear-Com unbalanced mode, so it drops into most house intercom systems.
