VA Series

Product Description

Professional high-end amplifier with excellent stability and reliability is highly cost effective.

The six models within this series (VA201, VA401, VA601, VA801, VA901, VA1201) offer a range from 130 watts to 1200 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements. Except VA201, there is elegant LCD in the VA front panel. LCD will show the info like working mode, temperature, DC protection, overload protection, etc.

VA series adopts Audiocenter latest Class H+ circuitry to eliminate the Class H cross switching distortion.

With carefully selected components like toroidal transformers, audiophile Wima capacitors, Toshiba transistors, Neutrik® connectors and Belden wires, etc. VA series has very clear and clean sound and high damping factor. This makes VA series suitable for any kind of application, from high power loudspeakers to critical monitoring where very high requirements are mandatory. It can be widely used in fixed installation and touring performance such as bar, nightclub, 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 VA amplifiers are able to sustain full power output even under complex capacitive loads.

 

Smart Overheat Management


The smart overheat management of VA 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


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