Descriptions
5 Zone Mixer Amplifier with XLR Balanced MIC Input and Phantom Power
The basic public address 5 zone mixer amplifiers have power ratings from 60W, 120W, 240W, 350W, 500W to 650W. They are featured of 3 balanced microphone inputs, 2 aux inputs and 1 EMC input. Priority muting is achieved via EMC for overriding other inputs except Mic1 on front panel. Individual gain controls are provided for Mic 1-3 and Aux 1-2, bass and treble controls and master volume control are provided for overall tone control. 70V, 100V and low impedance 4-16ohms speaker outputs are provided. Extensive protection from short-circuit, overload and high temp.
Optional
* DC 24V available on less than 500W models
* Panel with/without handhold
* Faults monitoring module, it can output short circuit signal to achieve main/spare amplifier switch
