  • Page 3: Introduction General Recommendations

    INTRODUCTION GENERAL RECOMMENDATIONS Safety precautions • The vehicle electric system must have 12VDC voltage with negative to ground. Make sure your car has it in order to avoid any damages to your amplifier and to the car itself. • Suitably fix the amplifier paying utmost attention if you install it into the driver’s compartment. Use extra fixing systems if you install it inside the bonnet.

    Therefore a new version of these classics may have changed their look, maybe also some of their features, but not their sound specifi cations. However there was still a way for Audison to try to improve, by merging these two unique characters into one amplifi er. This has been the idea of Audison engineers for a very long time.

    INTRODUCTION DESCRIPTION The fi nal power stage uses an innovative topology, which aims at increasing Class “A” polarization as much as possible. The whole input circuit is balanced up to the fi nal stage “Front End”, while the amplifi er’s confi guration is “Dual Mono”. In order to avoid electro-magnetic interferences, no high current is passed on the main board, with the exception of power supply terminals;...

    INTRODUCTION DESCRIPTION JFET differential input stage (available in PRE ON confi guration). Selectable two level input gain structure adjusted (available in PRE ON confi guration). Balanced output buffer for control unit (available in PRE ON confi guration). Thermally stabilized (available in PRE ON confi guration). Control Unit: Allows the amplifi...

This solution, which has been employed by Audison for a very long time, allows engineers to increase the impulsive current transient response necessary to the amplifi er.

    For cosmetic effect, the HV venti is equipped with three styles of lighting: the Thesis logo and glass perimeter red, the Audison logo blue, and the internals of the amplifi er are lit white. If the user removes the glass top plate, there are no electric wires to disconnect or reconnect, as electric contact automatically occurs through spring loaded contacts;...
