The MS-704 is a 2RU four-channel main station with 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 beltpacks or 10 speaker stations, or 12 headset stations.

The MS-704 accepts five separate program audio sources: four line-level balances inputs and one assignable line-level input. The assignable program input accepts a balanced signal and is designed for monitoring external audio. The four balanced program inputs can be used to create individual program feeds on the intercom channels. The MS-704 can monitor intercom activity on one or all four channels with individual volume level controls. Monitoring intercom activity is possible through a headset or the internal high-sensitivity loudspeaker.
