About: Clear-Com RM-704 4-Channel Headset/Speaker Station

Remote station provides four independent intercom channels, with programmable front-panel buttons for versatility. Separate volume controls for each channel and four separate audio program inputs via DB-15 Connector. Three IFB channels for talent cuing and announce button/relay for paging. Powered by the intercom line.

RM-704 Remote Station
The RM-704 remote station is powered directly from the intercom line and requires no external AC power, allowing it to be placed anywhere regardless of available electrical mains. The RM-704 has all of the same functions as the MS-704, except that it has no power supply, circuit breaker, or linking function.

Superior “Contoured” Audio
Compatible with all Clear-Com party-line intercoms, the 704 series accepts a wide range of dynamic headsets, with a choice of headset connectors. Optional plug-in noise-cancelling gooseneck microphones are available in 9” and 18” lengths.

Redundant “Failsafe” Power Supply
The 1.2-amp universal switching power supply is a 30-volt regulated supply with multiple short-circuit protection. It can sense the difference between a long-term short circuit and an instantaneous overload, allowing the intercom to continue to operate even when a station is plugged in, momentarily exceeding the capacity of the power supply. If a shutdown occurs from a shorted intercom cable, the power supply will recover under full load when the short is removed.

“Easy Access” Sub Panel
A removable front panel gives the operator easy access to the station’s configuration switches and trim pots. Clearly labeled and simple to adjust, these controls allow the station to be instantly configured for virtually any communications application. When configuration is complete, the front panel re-attaches, revealing only those controls useful for normal operation.

Multiple Program Audio Sources
The station accepts five separate program audio sources: four line-level balanced inputs and one assignable line level input. The assignable program input accepts a balanced signal and is designed for monitoring external audio in the headset or speaker. The four balanced program inputs can be used to create individual program feeds on the intercom channels. Three of these channels can be used for program interrupt.
