1. INTRODUCTION

Coming directly from the know-how of the exceptional Thesis line, Voce components takes the experience of listening
in the car to a new level of excellence.
Project innovation, advanced design, benchmark performance; the synthesis of consolidated know-how applied
to car audio systems. The Voce project was born to make Thesis sound quality available to a wider - but no less
demanding - audience. The development of these components took advantage of the major innovations introduced
while designing the Thesis line: analog and digital technologies combined using different classes of configuration for
amplifiers, reduction of the main sources of non-linear distortion, linearization of acoustic and electric loads, control of
cone and diaphragm resonance for speakers. To achieve these goals it was necessary to develop new circuit solutions,
increase heat capacity, design new moulds for baskets and diaphragms and define new assembly procedures and
quality control.
A delicate balance of analysis and refinement led us to results exceeding our expectations and set a new benchmark
for the category.

THE AV quattro AMPLIFIER PROJECT

AV quattro is a four-channel amplifier which can work in four, three, two channel mode, delivering 800 W (RMS)
power total. It is designed in order to handle complex configurations as front/rear and multi-channel systems.
Inputs and ARTTM ensure interfacing with every type of source; up to 24 dB/Oct. slope crossovers allow to build front­rear, front-sub or multi-amplified systems always having a non-filtered output signal to expand the system. AV quattro
also allows you to replace the analog input board with the digital one (AV bit IN).

AUDISON AMPLIFIERS CAN BE PART OF A HIGH POWER AUDIO SYSTEM THAT
CAN GENERATE VERY HIGH UNDISTORTED SOUND PRESSURE LEVELS.
PLEASE REMEMBER THAT LONG EXPOSURE TO AN EXCESSIVELY HIGH
SOUND PRESSURE LEVEL MAY DAMAGE YOUR HEARING; THEREFORE,
PLEASE USE COMMON SENSE AND PRACTICE SAFE SOUND.

Safety must be at the forefront while driving. The listening volume should never
obscure the noise coming from the outside of your vehicle; you should be able to hear the sounds generated by your
vehicle in order to promptly face any emergency situation.

To achieve the best possible performance from your new components, we recommend you follow the instructions
in this manual carefully. In order to design and create top level car hi-fi systems you need to understand automobile
mechanical and electrical issues very well; if you think you lack the required knowledge or the proper tools, please
consult with a specialized installer.
A professional installation will ensure your system delivers all the performance you have paid for, without affecting the
safety and reliability of your vehicle.

This manual has been designed to provide you with the basic instructions required to install and use this product.
However, the range of possible applications is very wide; to obtain further information, please contact your authorized
Audison dealer or Audison service center.

You can also send an e-mail directly to the following addresses:

4. GENERAL PRECAUTIONS

• This symbol indicates that you have to pay attention to these instructions. Disregarding them might cause
accidental harms or damage your amplifier.

• Before installing the amplifier, make sure you carefully read and understand all instructions.

• The vehicle electric system must have 12V DC voltage with negative to ground. Make sure your car has it in order

to avoid any damages to your amplifier and to the vehicle.

• Pre-plan the configuration of your new amplifier and the best wiring routes to ease installation.

• Always wear protective eyewear when using tools that may generate splinters.

• During installation, keep the amplifier in its packing as long as possible; this will protect it from damages.

• Secure all auxiliary devices you built to install the components to the vehicle structure through brackets, screws, nuts and bolts;

this insures stability and safety while driving.

• The amplifier detachment while driving can damage the people in the vehicle and other cars. Secure the amplifier at best, paying
utmost attention if installation is inside the passenger’s compartment. Do not carry out any installation inside the engine
compartment.

• Before installing the amplifier, turn off the source and all other electronic devices in the audio system for preventing any damages.

• Make sure the location you chose for the components does not affect the correct functioning of the vehicle mechanic and electric

devices.

• Do not run the cables or install the amplifier next to electronic gearcases.

• Use extreme caution when cutting or drilling the car plate, checking there are no electrical wiring or structural element underneath.

• Before connecting the power cable to the amplifier, disconnect the negative lead ( - ) from the car battery.

• Make sure power cable is not short circuited during installation and connection.

• Power cable must have mechanically resistant and self-extinguishing insulation. Its section have a size corresponding with what is

suggested in this manual. Avoid to run it over or through sharp edges or close to moving mechanical devices. Make sure it is well
fixed all along its length. Block positive and negative cables just close to the amplifier respective power supply terminal blocks
through a clamping screw.

• Use rubber grommets to protect the wire if it runs in a hole of the plate or proper materials if it is close to heat-generating parts.

• To ground the device ( - ) in the right way, use a screw in the vehicle chassis; scrape all paint or grease from the metal if

necessary, checking with a tester that there is continuity between the battery negative terminal ( - ) and the fixing point. If
possible, connect all components to the same ground point; this solution rejects most noise.

• Route all signal cables away from power cables.

• Never run cables outside the vehicle; you would not be protected against wear and in case of accidents.

• When installing speakers and the cables that connect them, make sure that non-insulated parts never touch, even occasionally,

the vehicle cutting parts. If they do, the amplifier protection is activated.

• To prevent all problems, use very good quality cables, connectors and accessories, choosing them in Connection catalogue.

• When installation is over, and before plugging the main power supply fuse, check the system wiring and make sure all

connections were done in the right way.

• Power amplifiers put an increased load on the battery and on its charging system. We recommend checking your alternator and
battery condition to ensure they can handle the increased consumption. Standard electrical systems which are in good condition
should be able to stand this extra load without problems but we recommend the use of an energy storage capacitor and/or a
battery for high level audio systems.

• Put a fuse and its insulated fuse holder 40 cm max. far from the battery positive terminal; connect one end of the power cable to it
after connecting the other end to the amplifier. The fuse value must be 50% higher than the amplifier built-in one. In case the
cable supplies several amplifiers, the fuse value will have to be 50% higher than the sum of the values of all other fuses in the
amplifiers.

• There must be good air circulation where the amplifier is installed; this area must not be affected by humidity, rain, external
deposits or parts coming from the vehicle mechanical devices. Do not hinder in any way the cooling of the amplifier side fins

• Install the amplifier in the vehicle parts where temperature is between 0°C (32°F) and 55°C (131°F).

WARNING. When working in demanding conditions, the amplifier can reach temperatures of around 80 - 90°C

(176 ÷ 194°F). Make sure it is not dangerously hot before touching it.

• Periodically clean the amplifier without using aggressive solvents that might damage it. Dampen a piece of cloth with water

and soap, wring it and clean the amplifier. Then use a piece of cloth dampened with water only; eventually clean the amplifier
with a dry piece of cloth.

• Remove dust and solid deposits from the heat sink side fins. Don’t use compressed air on the amplifier since it would push

solid parts in the amplifiers. If necessary, please contact a specialised service centre for internal cleaning. Cooling system
obstruction makes the amplifier go in safety mode.
