Product Description

Audison Thesis HV Venti

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. The Thesis brand, which indicates absolute Hi-End audison products, aims at escaping this indisputable reality.
Thesis doesn't want to be a complete line of products, since only when Audison continuous research proves that something really special in terms of ideas, performances, materials may be created, can the development of a Thesis product begin.
If a product doesn't meet these "utmost" features, it will not be a Thesis, although it will sport the Audison brand, which always means top level performance.
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.

• 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.

is a stereo Dual Mono amplifier realized according to absolute Hi End parameters.
Four power supplies, low feedback, high bias current: these are only some of the adopted solutions to obtain reference performances.
Through the developing of HV venti project many technological
innovations were introduced in audio field.
Dual Power lets you set up final stage in two output power
configurations, Hi Current or Hi Power. This function permits
total conformation to loudspeakers impedance and power
handling specifications.
The preamplifier PCB is able to dissipate the heat generated
by the active devices while keeping their working temperature
at the same level and positively affecting sound.
In order to let you admire the masterpiece Audison designers
created the electronics is covered by a special tempered
scratchproof glass and it is lighted by several white, red and
blue leds positioned in strategic spots.
