The crown of the Plug & Play amplifier series – with its incredible performance capabilities on an ultra-small footprint, the PP 82DSP outshines all the previous models that came before it. With its enormous range of functions, thanks to Audiotec Fischer´s unique Class HD technology, it is setting a whole new standard in terms of efficiency. The combination of state-of-the-art digital amplifier technology and a dynamically-controlled switched-mode power supply reduces heat generation and power consumption to an absolute minimum. But that´s not all - no less than eight separate and freely-configurable amplifier channels with incredible power enable even sophisticated system configurations with one single amplifier.
