DF-series

DF-series is a series of professional switching amplifiers, which includes two-channel or four-channel amps with output power from 4 х 350W to 2 х 1600W.

The DF-series amplifiers have high efficiency class D topology with least heat and high sound quality, comparable with the best analogue amplifiers.
Modern switching power supply not only minimizes the weight, but also provides reliable and faultless operation of the amplifier.
