The Adastra CS4 is a Paging Microphone and Call Station, designed to be used with the Adastra RM244V Mixer Amplifier. When used with the RM244V, the CS4 offers 4 zone paging without the requirement or cost of using a quad amplifier. Zone assign buttons allow for intuitive calling to any of the 4 zones or to all zones, with the page button automatically muting audio playback in those areas for clear vocal announcements.

There are 8 paging chimes to choose from, as well as a 3.5mm auxiliary audio input allowing you to broadcast pre-recorded messages and alerts. The CS4 comes with a 1m RJ45 patch lead to connect the microphone to the RM244V, which conveniently passes both the signal and powers the unit, however remote wiring is also possible via CAT5 lead up to 1km when using the optional 24V DC adaptor.
