Adastra CS4 Call Station for RM244V

Desk paging microphone with call station base for use with the RM244V mixer-amp. Connected via RJ45 for both signal and power to simplify wiring. Zone assign buttons enable calling to one or all zones. Pressing the page button mutes all audio playback and plays one of 8 selectable chimes, opening the microphone to the selected zone(s). Pressing the reset button mutes the microphone and resumes background music playback to all zones. This system offers 4-zone paging without the additional cost of using a quad amplifier.
