DUAL POWER & BIAS CONTROL
A revolutionary function called Dual Power was introduced for the first time in the HV venti.
Controlling the amplifier's output power configuration, this function allowed the predetermination of the
amplifiers output power and of the grade of the outputs operational class. The digital interface enables
expedient intervention by the user, setting up the amplifier's operational modes by operating on the power and
bias current settings, all in real-time. In any case the result is a clear "sound customisation".
In this Setup section you can set the amplifier operational mode.
There are four possible presets:
Class A: to intensify the musical performance; you can not expect the amplifier to drive loads under 4 Ω
under these conditions;
Hi-AB Class: it is the default mode, combining the characteristics of high class functioning, great capability
of driving difficult loads and high power.
Hi-Current: Pure power, on any loads
Energy Saving: it sets the power emission to the minimum, allowing musical enjoyment for extended
periods of time with the vehicles engine off.
When changing mode, you have to wait a few seconds to perceive the acoustic variations. The Dual Power is
absolutely indipendent from the other settings selections. It will work both in Mono and in Stereo
configurations, both with and without the crossover, both connecting a subwoofer and a tweeter to it. So we
recommend you pay attention to select a functioning mode accepting the impedance load you applied to the
amplifier. Check the following page for comparative charts with reference values.
