VX-series

VX-series is a series of classical professional power amplifiers with natural cooling.
VX-series amplifiers have high efficiency analog H-class topology and classic power supply, based on toroidal transformer.
Natural cooling system and, as a result, no acoustic noise, combined with high quality sound, gives possibility to use it for installing in the recording studios.
