A Series Power Amplifier

Professional Amplifier with remarkable performance and reliability

The three models within this series (A5.0,A7.0,A13.0) offer a range from 600 watts to 1300 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements.

A series adopts Audiocenter latest Class H+ circuit to eliminate the Class H cross switching distortion.

A series adopts carefully selected components like toroidal transformers, high-quality capacitors, Onsemi transistors, Neutrik input connectors and superior audio wires, etc. High quality materials and technology ensure the reliability and safety, which makes A series suitable in any kind of extremely cold, hot or wet working environment. It can be widely used in fixed installation and touring performance such as entertainment venues, multi-functional hall, museum, religious venue, commerce site, lecture hall, wedding ceremony, 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 A amplifiers are able to sustain full power output even under complex capacitive loads.


Smart Overheat Management

The smart overheat management of A 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

A 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 A amplifiers have less than 0.1%THD at 16KHz and the sound is so clean and natural.


Comprehensive Protection System

A series is with comprehensive protection system including short circuit protection, overload protection, DC protection, overheat protection, limiter protection and soft startup, which make the sound system more safe and reliable.
