ACP Series

Model List
Product Description

A professional and high-end SMPS power amplifier, is famous for its stability, high-efficiency and light weight

The three models within this series (ACP4.0, ACP6.0, ACP8.0) offer a range from 450 watts to 800 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements.

ACP series adopts Audiocenter latest Class H+ circuit for ACP4.0, ACP6.0, ACP8.0. Class H+ circuit eliminates cross switching distortion.

ACP series 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 ACP series 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.

A-Guard Protection System


A-Guard is Audiocenter comprehensive protection system which includes optimized limiter circuit. Unlike other solutions which depend on separate circuits to address different problems, A-Guard was developed as centralized solution where all protection requirements work together in perfect harmony. A-Guard is only applied when it’s necessary to protect the amplifier. This is the reason why ACP amplifiers are able to sustain full power output even under complex capacitive loads.

 

Smart Overheat Management


The smart overheat management of ACP series adopts unique circuitry to monitor the amplifier’s temperature in real time. When the safe operation of the amplifier is compromised, the output power is reduced but not shut down, which ensures the system can work stably in high temperature environment.

 

Class H+ Circuit Design Eliminates Cross Switching Distortion


ACP series adopts Audiocenter latest Class H+ circuit to eliminate the Class H cross switching distortion. The result is the same low distortion as Class AB. All ACP amplifiers have less than 0.015%THD at 16KHz and the sound is so clean and natural.
