Description

Clear-Com IF4BD Intercom Interface 4 Wire- 2x Module Version

The IF4-B modular 4-wire interface connects camera intercoms, two-way radios, fiber optics, and other 4-wire devices to a standard Clear-Com intercom line. The 1-RU chassis holds up to four individual interface modules, each with its own 4-wire terminal block and XLR-3M connector to interface with Clear-Com.

Featuring broadcast-quality circuitry, the unit matches industry-standard 600-ohm transmit/receive lines (at normal levels) to Clear-Com line level. The IF4-B accepts balanced or unbalanced 4-wire input and is transformer isolated. It is powered by the Clear-Com intercom line, using standard two-conductor shielded mic cable.
