ACP4.0

Product Overview

ACP4.0 offers 450 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements.

ACP4.0 adopts Audiocenter latest Class H+ circuit which eliminates cross switching distortion.

ACP4.0 adopts carefully selected components like audiophile WIMA capacitors, Rubycon capacitors, Onsemi transistors, Neutrik® connectors and Belden audio cables, etc. High voltage signal and low voltage signal are allocated separately for better performance. The power supply part is covered with steel shield. The best components selected for the category and the advanced technology ensure very clear and clean sound. This makes ACP4.0 suitable for many different kinds of applications, from high power loudspeakers to critical monitoring where crystal clear highs are mandatory. It is widely used in concert, stadium, theater, opera house, etc.
