Description:

It is a new generation of high-power professional digital amplifier, which is characterized by high efficiency, stability and excellent sound quality. It has broken through the traditional technology in power technology, modulation technology and control technology, so as to substantially improve the overall performance. The application of variable oscillator modulation technology, multiple feedback control technology and innovative output power control technology endow the amplifier with over 95% ultra-high efficiency and excellent stability. And it is specially applicable to large-scale sound reinforcement venues, tour performance multipurpose halls, etc.

Feature:

* Support DC, short circuit, overload and overheat protection;

* Designed with Signal (green), CLIP (orange), Fault (red), Power (blue) indicators on the panel;

* Support XLR balanced input; SPEAKON audio socket output;

* Support signal, power, temperature and other voltage limiting functions;

* Support optional three modes: MONO/STEREO/BRIDGE;

* Support optional 1V/2V sensitivity;

* With a temperature-controlled fan, it rotates as soon as it is turned on; the fan accelerates as the temperature rises, and reaches full speed at about 60℃;

* Super load capacity: support 8 ohms, 4 ohms, and minimum 2 ohms.
