MA200 is a 200 watts 100 volt mixing amplifier with 4 output zones. This professional public address system has 4 balanced microphone inputs with integrated speech filters, paging priority switch, vox circuitry, built-in ding dong chime, three stereo and one mono line input on RCA connectors and an emergency input. Stereo line inputs are internally mixed to mono.The output zone selectors on the front of the MA200 allow you to switch on/off a zone (zone 1 – 3) or to switch on/off music and paging for zone 4. A built-in limiter on the outputs protects your sound system and the dynamic filters on the microphone outputs contribute to high intelligibility.This mixing amplifier has a 3-level priority system where the emergency line / telephone input at the back has the highest priority. MIC1 has the second priority level and the third priority level can be activated by a dry contact at the back of the amplifier that mutes all background music inputs and activates the integrated chime.The MA200CDR has all the features of the MA200 but also with extra integrated AF/FM tuner and a CD/MP3 player.
