The Clear-Com CS-702 2-Channel Portable Headset Main Station designed for Encore 2-wire analog partyline intercom systems. It supplies regulated DC power to connected beltpacks and speaker stations while providing clear, intelligible communications in demanding production environments. Operators can monitor either channel independently (or both at once) via headset, earphone, or speaker, with individual listen controls for each channel. Built-in call signaling, adjustable sidetone per channel, and dual-action talk controls (momentary or latching) keep communication fast and intuitive. The CS-702 also adds practical production features like a balanced program input with selectable program interrupt, Remote Mic Kill to clear open mics, and a stage announce output with relay for paging and external control.
