Telex IFB-3251-CH IFB Beltpack

The IFB-325 is a single-channel, listen-only IFB beltpack that delivers one mono program feed to a talent or crew member in the field. The feed can be interrupt or non-interrupt, chosen upstream at the 4010 central IFB station, so a director can duck program to talk directly to the wearer. A front volume control lets the user set a comfortable level in their earpiece.

Everything lives in a rugged extruded aluminum case that survives being clipped to a belt and worked all day, and a 1/4 in jack accepts an announcer earset such as the CES-1. The unit runs on 32 VDC nominal supplied over the IFB line, measures 3.75 in wide by 1.5 in high by 1 in deep, and weighs about 16 oz. RTS part number F.01U.118.564.
