PRO4.0 offers 400 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements.
PRO4.0 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, Carling switch circuit breakers, Neutrik®connectors and Belden wires, etc.
PRO4.0 has very clear and clean sound and high damping factor. This makes PRO4.0 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.
