Amps are digital class-D high power amplifiers with PWM technology. The device has a superior efficency (90%), fidelity of signal, reliability and an extremely high frequency response. Furthermore this serie is equipped with a complete safety package against temperature, overload, short circuit, equivalent voltage at the output and fast cut off if there is a power failure. Two radial fans with high efficent air circulation front-to-rear provide highest thermic stability. Even the changing of the dustfilter is very easy, you just have to put off the front grille.You can see the operating model for signal, limit and protection on a 4-character LED display per channel. The solid 19'' metal housing is equipped with an alluminium front panel, therefore it is light weight and compact. The device has small dimensions and an excellent power/weight balance because there are no built-in heavy transformers, on the rear panel, there are symmetrical electronic signal inputs via two XLR- and two Jack input sockets and two outputs with locked speakers sockets. They are siutable for compact and multi-purpose sound, rental, disco and live events.
