The Clear-Com HB-702 is a two-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 multichannel, full-duplex headset communications panel is desired.
The unit mounts in a standard U.S. two-gang outlet box. The stations offer excellent speech intelligibility even in high noise environments. Microprocessor-controlled logic plus a set of internal and external controls allow the features of these stations to be tailored to your needs. 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. The two-position switch on the HB-702 allow you 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.
