Product Description
Audison has always aimed at the highest quality. Every product is unique. It is designed and developed in order to join the very best worldwide production; its special features make it peerless.
Sometimes, however, choices have to depend on technical reasons, on the fact the product must be easy to use, on market demands. Thesis line, which indicates absolute Hi-End audison products, aims at escaping this indisputable reality. Thesis is a direct link between audiophile designers and audiophile enthusiasts, who always, simply, look for the best in a common passion: listening to music.
Thesis HV venti is a stereo amplifier built accoridng to absolutely Hi-End parameteres.

• Innovative “Dual Power” function allows to configure the amplifier for two output power sets: Hi Current or Hi Power.
• “Dual Bias” selectors permit to change Class A percentage and the amplifier related idling current.
• Crossover module with selectable cut-off frequency provided as accessory. In order to insert it, bypass module has to be removed, so that when the crossover isn’t used, signal path is minimized.
• Cooling system realized with heatsink, natural convection, and a pair of fans for each heatsink side which let air flow within side cooling ducts.
• ASC (Amplifier Status Control): microprocessor based unit designed to manage every amplifier operations. It shows amplifier temperature, protection and others important information about its the status.
• Innovative output power stage topology, discrete IGBT, realized with a complementary pair of Hitachi DMOS driving two pair of complementary Sanken power BJT, each rated for 30A peak current and 200W dissipation.
• Balanced Class A biased driver with separate 150V Flyback power supply.
• Thermally stabilized with central fan independent from the others on the side ducts.
• Fully balanced JFET differential input preamplifier with output buffer for control unit.
• ABS inputs and ABS bypass outputs, decoupled through two audio-grade polypropylene capacitors per channel.
• Four Synchro-PWM power supplies allow to obtain very fast transient current response and to realize Dual Mono configuration.
• Wide range of protections: power limiter in case of loudspeakers shortcircuit or overload, over 90°C thermal protections, power output terminals shortcircuit to vehicle chassis, battery protection operating with voltage lower than 11V or higher than 16V, DC at output terminals, power supply fuse.
