Clear-Com SB-704



The 704 series is Clear-Com’s most advanced party-line intercom system. Each station is a four-channel intercom with superior audio and versatile channel access to provide unmatched communication fexibility. All front-panel controls are intuitive and easy to operate. The station’s front-panel buttons are programmable and can be customized for a wide variety of applications that will meet the demands of any stage, studio, or held producer. Separate volume controls for every channel ensure the perfect audio mix in the headset or on the integral speaker. The SB-704 includes a versatile switching matrix which allows up to ten different groups of stations to be assigned to any one of the four channels. The regulated power supply in the MS-704 and SB-704 provides power for the entire intercom system.

This station is similar to the MS-704 main station except the speaker is replaced by a 10 x 4 assignment matrix panel. The assignment matrix panel allows you to choose any intercom station or group of stations connected to the ten inputs of the matrix and assign them to any one of the four intercom channels.
