Audison HV Venti

HV Venti Amplifier | 1600 W total power | 2 x 800 W @ 2 ohms | Class A

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 uncompromising performance, this amplifier represents the pinnacle of audio technology, with features unique in its class.

The HV Venti's Dual Mono configuration uses four Synchro-PWM power supplies, ensuring extremely fast response to power transients, improving sound quality. The input circuitry is fully balanced all the way to the power stage, while the entire amplifier configuration eliminates electromagnetic interference by routing it away from the main board.

Another significant innovation in the HV Venti is its output stage, based on a hybrid MOSFET-BJT topology that uses discrete components to improve efficiency and heat dissipation. This solution allows a high bias current to be maintained on each output device, increasing Class A efficiency.

The HV Venti offers a Dual Power feature that allows the output to be configured in two modes: Hi Current and Hi Power. This flexibility allows the amplifier to adapt to the impedance and power handling of the connected speakers, optimizing audio performance to specific needs.

To ensure the highest sound quality, the preamplifier uses fully balanced JFET differential stages with an output buffer for the control circuit. In addition, the progressive cooling system ensures that the operating temperature of the active components remains constant, which positively affects the sound quality.

The amplifier features a scratch-resistant tempered glass surface and strategically placed white, red, and blue LEDs, allowing you to admire the complex and beautiful internal design.

In conclusion, the Audison Thesis HV Venti is an amplifier that combines technological innovation, elegant design and outstanding audio performance, making it a reference point in Hi-End car stereo.
