PR Series - analog heavy duty/high-performance amplifiers

Models : PR 700, PR 900, PR 1200, PR 1500, PR 2000

The professional output-amplifiers of the PR Series represent the "high end" of the amplifiers concerning output per weight in a tightened steelcage/case/frame with a massive front coverof lightweigth construction on 2HE. By reason of the latest HEF circuit technology these amplifiers reach a 20% better output at 1/3 subordinated weight as coventionally buoyed systems.

The output-amplifiers are equipped with a stabilised power pack, that contains a 4-stepped modulation to the current output requirements of the MOS-FET / bipolar solid state outputgrade. This "Dynamic Power Management" allows high "slew rates" while the output voltage follows dynamic digital signals, without compromises in the low bass consistency.

All systems allow full 2W operation or 4W jumper/link operation at concurrently low loss of heat at full-load operation (meinst du Volllastbetrieb?...für Vollastbetrieb find ich keine Überstzung).The amp’s are equipped with limiters, "no fault safety circuit", ventilator and massive access- and output/outlet-connectors. Thereby an easy cabling in the system in each situation is guaranteed.
