The ClearCom Encore RM-704 is a 2RU four-channel intercom remote station with programmable front panel buttons and individual channel volume control. The RM-704 is powered directly from the intercom line and requires no external AC power. Encore™ is a 2-wire analog partyline system with intuitive plug-and-play design and superior "Clear-Com Sound" audio quality. The RM-704 is powered directly from the intercom line and requires no external AC power.
The RM-704 can monitor intercom activity on one or all channels with individual volume level controls. Monitoring intercom activity is possible through a headset or the internal high sensitivity loudspeaker. The RM-704 has mic pre-amps with limiters and individual electronic momentary/latching Talk button on each channel. The channels can be accessed separately or simultaneously without tying them together. A selector switch toggles between the headset or microphone.
