Audison HV venti

The Audison Thesis HV Venti is one of the most exclusive high-end amplifiers in the car hi-fi sector and has been uncompromisingly developed for maximum sound fidelity. As a dual-mono Class-A amplifier, it combines exceptional engineering skills, innovative circuit technology and the highest material quality in a reference product of the Thesis series.

At the heart of the HV Venti is fully balanced signal processing combined with four separate Synchro-PWM power supplies. This sophisticated design enables an extremely fast response to current transients and ensures exceptional dynamics, control and naturalness in the sound image. The specially developed MOSFET-BJT hybrid power amplifier uses discrete components and combines high efficiency with the sonic benefits of a true Class A design.

Thanks to the "Dual Power" technology, the amplifier can be flexibly configured between Hi Current and Hi Power mode, allowing the HV Venti to be optimally adapted to different speaker and impedance requirements. The concept is complemented by a fully discrete preamplifier section with symmetrical JFET differential stages and sophisticated thermal management for constant stabilization of the operating temperature.

The HV Venti also sets visual standards: the solid aluminum housing, the visible high-end electronics under tempered glass and the integrated LED lighting underline the uncompromising claim of this exceptional amplifier. The Audison Thesis HV Venti is aimed at the most demanding music lovers and is consistently designed for absolute sound quality, transparency and musicality.
