The basic public address mixer amplifiers have power ratings from 60W.

They are featured of 3 microphone inputs, 2 aux inputs, and 1 EMC input.

Priority muting is achieved via EMC for overriding other inputs except for Mic1 on the 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

4-16Ω speaker outputs are provided. Extensive protection for short-circuit, overload, and high temp.


* Mixer amplifier for paging and background music system.

* Rated power from 350W.

* 2U rackmount design.

* 70V, 100V, and low impedance 4-16Ω speaker output.

* Three Mic inputs by phone jack type.

* Mic 1 with VOX priority and VOX level on the front panel.

* Mic 2-3 by phone jack on the rear panel.

* Two Aux Inputs and 2 line inputs for spare use.

* One EMC priority input.

* EMC has priority over all inputs except MIC1.

* Mic 1-3, Aux 1-2, and master volume controls and bass/treble tone control.

* Short circuit, overload, and high temp protection.


* DC 24V is available on less than 500W models.

* Panel with/without a handhold.

* Faults monitoring module, it can output short circuit signal to achieve main/spare

amplifier switch
