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;...

However, they are synchronized with one another and are designed to supply one single power source, one supplies the positive and the other the negative power. 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;...
Once fi lters are dried, they can be put back to their place. Do not use an external heat source to dry the foam fi lters. Now you can remount the grilles. You can fi x them in four different ways according to which Audison logo side you want to be visible.

OWNER’S MANUAL POWER SUPPLY - SWITCHING ON PANEL 1 • - POWER (GROUND) Terminal block for the amplifi er power supply negative pole connection. Connect the battery negative cable or the one connected to the vehicle chassis to it. Holes have 9.5 mm (.37 inches) diameter and accept cables up to 2 A.W.G. For better current transfer, power supply cables have to be as big as possible.
OWNER’S MANUAL CONTROLS PANEL 1 • OUT MODE It permits to confi gure the amplifi er in STEREO or MONO. If you put Out Mode control on STEREO, PRE IN LEFT and RIGHT inputs signals are separately amplifi ed and they are in SPEAKER LEFT and RIGHT outputs.
