    MS-704 - Overview

    Supports up to 55 beltpacks!

    The ClearCom MS-704 is a 2RU four-channel main intercom station at the heart of the Encore Partyline Intercom System. The MS-704 features programmable front panel buttons, individual channel short-circuit protection, individual channel volume control, and a regulated fail-safe power supply. The MS-704 supports up to 55 RS Series beltpacks, 10 speaker stations, or 12 headset stations! (sold separately)

    The MS-704 has a removable front panel for easy access to the station's configuration switches and trim pots. Clearly labeled and easy to adjust, these controls allow the MS-704 to be configured quickly. When configuration is complete, the front panel can be reattached so it shows only the needed controls.
