HB-704 Four-Channel Station
The HB-704 provides the same features as the HB-702,
but can access four intercom channels.
The HB-704 is a four-channel-selectable, full-duplex headsetstation, able to be mounted into a wall or other surface. These headset stations are ideal for installation in theatrical, performance, broadcast, and industrial facilities - wherever a multi-channel, full-duplex headset communications panel is desired. This 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 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.
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 on the HB-704 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 stations may be used with the optional TW (two channels on a single mic cable) daughter board. With the TW board, the stations become plug-in compatible with a Clear-Com TW system. The HB-704 is housed in a durable package with a steel front panel.
THE CLEAR-COM CONCEPT
Clear-Com is a closed-circuit intercom system that consistently provides high-clarity communication in high-noise and low-noise environments. A basic system consists of a single- or multi-channel power supply or main station connected to various single- or multi-channel remote stations, such as beltpacks and loudspeaker stations. Clear-Com manufactures a wide variety of both portable and fixed-installation units. All are compatible with each other. Clear-Com intercom systems can also interface with other communication systems and devices.
Please Note! This item is just one component of a larger system. Please refer to the diagram for ideas and recommendations for your Clear-Com intercom system. Although the HB-702 is pictured in the diagram, the HB-704 can be easily substituted.
