Signal processing and power amplification appears in another light today than just a couple of years ago. New and advanced technologies have irreversibly changed the market for electronic operational sound products.
With the dawn of new digital possibilities the PR electronic engineers have not forgotten about the good tradition of perfect analog sound engineering and added the wide range features coming up with new technologies on top of this proved basis.
Due to this experience PR electronic can offer a spectrum of sound signal processing devices from matched analog system controllers above digital sound processors, featuring DSP technology, to new generation power amplifiers with heavy duty performance possibilities.
The key features are adjustable crossover filters, soft knee limiters with variable threshold, pre programmed frequency and equalization adaptation to PR speaker systems or at least system matched signal tools at the signal side.
For the power side - amplifiers with included clipping eliminators, full 2 Ohm ability at reduced weight, lowered power loss due to HEF-Switch® technology united in a small 2 HU package.

Besides these features inside, PR electronic engineers also took care about the peripheral equipment. They set new standards of easy work during hook up (Easy Connect®) of a single system or a combination between several units resulting in an impressive large frame PR sound system.

Digital Power Amplifier
The PR D Series Professional Digital Power Amplifier represent the high end of power amplifiers in regards the ratio between power
and weight. Due to state of the art circuit technology this amplifiers are reaching about 100% more output power at 50% less weight in
comparison to "usual" power amplifiers.
