The 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 multi-channel, full-duplex headset communications panel is desired. The unit mounts in a standard U.S. two-gang outlet box. This station offers excellent speech intelligibility even in high noise environments. Microprocessor-controlled logic plus a set of internal and external controls allow the features of this station to be tailored to the needs of the user. Electronic switching for the talk button, blue-color LED (on) or amber-color (off), permits momentary or latching operation. A Remote Mic Kill (RMK) signal on the intercom line will turn off the talk function if it is accidentally left on.
