Clear-Com HB-704 Encore 4-Channel Remote Headset Station

The HB-704 is a four-channel-selectable, full-duplex headset station, able to be mounted into a wall or other surface. This headset station is ideal for installation in theatrical, performance, broadcast, and industrial facilities – wherever a multi-channel, full-duplex headset communications panel is desired.

The HB-704 mounts in a standard US two-gang outlet box. The station covers excellent speech intelligibility even in high noise environments. Microprocessor-controlled logic plus a set of internal and external controls allow the features of the station to be tailored to the needs of the user. Electronic switching for the talk button, blue-color LED (on) or amber-color (o), permits momentary or latching operation. A Remote Mic Kill (RMK) signal on the intercom line will turn o the talk function if it is accidentally left on. A red-color LED tracks the incoming call signal, so it can be used for visual cueing.

An associated call button allows the user to place a call signal on the selected intercom line. The standard 4-pin XLR headset jack accommodates Clear-Com and compatible dynamic headsets. A sidetone level control adjusts the amount of the user’s voice heard in the headset. An automatic limiter circuit adjusts and limits the microphone output to the intercom line. A four-position switch allows the user to select from the attached intercom channels. Connections to the intercom lines are made via a screw-terminal block, using standard two-wire shielded mic cable.

The station may be used with the optional TW (two channels on a single mic cable) daughter board. With the TW board, the station becomes plug-in compatible with a Clear-Com TW system. The HB-704 is housed in a durable package with a steel front panel.
