PD-650 professional power amplifier


◆ PD series using SMT production process, Class-H circuit technology, excellent circuit layout; ◆ Closed-loop control of peak limiter, soft start, short circuit/over current, over voltage, perfect protection circuit; ◆ Grade A iron core and oxygen-free copper enameled wire power transformer make the energy more sufficient and the working temperature more bottom; The use of higher power amplifier tube, further optimize the sound, continue to provide surging driving force; ◆ Audio dedicated capacitor, less distortion, lower internal resistance, faster and stronger charge and discharge current; ◆ The function of gradually increasing the sound of starting up can effectively protect the speaker at the moment of starting up; ◆ With display can display temperature, volume size, protection function; The fluid mechanics design, reasonable natural air cooling and forced air cooling, ultra quiet operation, can withstand relatively harsh environment work; ◆ The panel with aluminum alloy wire drawing process is more stable and high-grade, which is more in line with the aesthetic standards of modern people. The panel ventilation net cover can be disassembled to facilitate cleaning of dust accumulated in the heat dissipation channel; ◆ Three working modes, stereo parallel and bridge, and with ground on-off selection switch.
