Audison HV venti Stereo amplifier with ABS inputs and "Dual Power"

The Audison Thesis HV Venti is a Dual Mono stereo amplifier designed to meet the highest Hi-End standards, the result of extensive research and development to achieve uncompromised performance. This amplifier represents the pinnacle of audio technology, with features that make it unique in its category. The Dual Mono configuration of the HV Venti uses four Synchro-PWM power supplies that guarantee an extremely rapid response to current transients, improving sound quality. The input circuit is fully balanced up to the final stage, while the entire amplifier configuration avoids electromagnetic interference thanks to external routing away from the main board.

Another significant innovation of the HV Venti is its output stage, based on a hybrid MOSFET-BJT topology, which uses discrete devices to improve efficiency and power dissipation. This solution allows maintaining high bias current on each output device, thus increasing Class A efficiency. The HV Venti offers a Dual Power function that allows configuring the output in two modes: Hi Current and Hi Power. This flexibility allows the amplifier to adapt to the impedance specifications and power handling of the connected speakers, optimizing audio performance based on specific needs.

To ensure maximum sound quality, the preamplifier uses fully balanced differential JFET stages with an output buffer for the control unit. Additionally, the progressive cooling system ensures that the operating temperature of the active elements remains constant, positively influencing sound quality. The amplifier is equipped with scratch-resistant tempered glass and strategically positioned white, red and blue LED lights, allowing you to admire the complexity and beauty of its internal design. In summary, the Audison Thesis HV Venti is an amplifier that combines technological innovation, elegant design and unparalleled audio performance, establishing itself as a reference point in the world of Hi-End mobile electronics.
