Amp Controller-Series

DSP-Amplifiers + DSP-Controller.

DSP amplifiers and DSP system controller
A perfect solution for demanding fixed installations and mobile applications. Optional remote control. Monitoring function. Network-compatible.

State-of-the-art amplifier technology.
Our active speaker systems and external 19” amplifiers are equipped with state-of-the-art CLASS D technology and were developed to meet the most demanding requirements for audio quality and reliability in fixed installations and mobile applications.

The main advantages of the CLASS D amplifiers are:
the low weight and compact dimensions, outstanding sound quality and a high degree of efficiency that minimises heat development inside the amplifiers considerably compared to conventional analogue amplifiers. The amplifiers require minimal cooling and always operate reliably as a result.

FC-9 DSP system controller.
Automatic calibration function and integrated speaker management system provide maximum protection for amplifiers and speakers.
