The Power Conditioner 948 is one of our most innovative products and is the result of many years of basic research. Burmester Audiosysteme identified a very small level of DC voltage amounting to no more than a few mV DC, which is always and to varying degrees superimposed on the mains AC voltage, as the reason for the phenomenon of sound loss at various times of the day. The patented principle for the loss-free elimination of these vestiges of direct current is an active amplifier system that works in parallel to the electric power supply, and this makes it possible to attach large amplifiers without the sort of power limitation that can have an adverse effect on the sound quality.
