AV quattro Amplifier | 800 W total power | 4 x 200 W @ 2ohm | AB-class

AV quattro
is a four-channel amplifier capable of working in four, three, or two-channel
modes, and delivering a total power of 1700 W (RMS).

It is
designed to handle complex front/rear and multichannel system configurations.

(Amplifier Management Processor) constantly monitors the operating status of
the operating system and communicates with the user through 4 different colored
LEDs located on the top panel.

ART (Automatic
Remote Power On/Off) enables automatic power on/off when no remote signal is
available from the source.

with cut off slope up to 24 dB/oct. allow for front-rear, front-sub or
multi-amplified systems while always having an unfiltered signal available at
the output for system expansion.

AV bit IN HD
AV bit IN HD
Digital interface for all AV amplifiers, for perfect digital connection with Audison bit processors provided with AD Link and AC Link connections. By mounting the AV bit IN Digital Interface onto the Voce amplifier series, through the AD Link connection the S/PDIF digital signal will get directly to the high quality internal D/A converters. After these, the signal becomes analog and is imm ediately amplified preventing it from deterioration due to the long paths. The result is extremely high quality music, not achievable with any other analog system. It offers one AD Link and AC Link input, as well as one AD Link and AC Link output in order to drive a multi-amplified system. Thanks to its digital panel with 3 character display and 4 push buttons, you can select the amplifier type, mono or stereo mode, and also the digital channel coming from the audio processor. AV bit IN HD features two new switches on the front panel: one provides you with the ability of turning off the gain control of the amplifier to achieve an improved Signal to Noise ratio. With the second switch you can control the DSP remote start function. Connection to amplifier: remove analog crossover module and insert AV bit IN module into the amplifierâ„¢s front side. It requires no external power supply.
