PowerH 5000 test in `Production Partner` 10/2007

PowerH Series

“All in all, a perfect combination, in which it is evident from every detail that the developers knew exactly what a high-end power amplifier for the professional touring and installation market needs.”

The power amplifiers of the PowerH series represent a milestone in the design and production of high-performance power amplifiers.

Their innovative multi-stage Grounded Bridge Class H topology with its floating switching power supply offers very high and stable output power, very high efficiency, an extremely high level of audio performance and extremely low weight.

They are therefore the ideal drivers for professional touring and high- end concert sound, as well as pro sound, applications. Through the use of IRIS-Net-compatible remote control modules, they also offer extensive remote supervision and control functions as well as a uni- versal two-channel digital controller including ultra-precise FIR filtering and digital algorithms to protect

the loudspeakers. DYNACORD power amplifiers are known for their absolute reliability under the most arduous of conditions on the road. Naturally this is also true of the PowerH models.

In addition to the legendary manu- facturing quality that comes with the ‚Made in Germany‘ label, the comprehensive set of protective circuits plays an important role here: an integrated micro-controller coordinates tried-and-tested protections against short-circuit, HF or DC at the output, back EMF, overheating and open-circuit opera- tion, the power-up current limitation and dynamic audio limiters as well as making additional new and high- ly intelligent protective functions possible: for example, the tempe- rature in the power amplifiers is monitored at no fewer than six dif- ferent points and the front-to-rear ventilator governed accordingly.

Under abnormal thermal ‚worst case‘ conditions, the CPU activates a voltage limiter or gain reduction depending upon the requirements of the situation, so as to obviate the need for a thermal shutdown of the power amplifiers. All corrective measures are indicated by LEDs on the front panel and detailed clearly on the liquid crystal display. In addition, a report is created making it possible to enquire later as to all such ‚interventions‘, each of which is time-stamped.

The mains voltage is monitored and displayed continuously, with the devices adapting automatically to 230 V, for example, or 120 V. At the same time, the mains current consumption is also monitored and displayed. The trip value of the au- tomatic circuit breakers can be set by the user via the display of the power amplifier to prevent the cir- cuit breakers tripping. Any short-
