Frequently Asked Questions - VOCE AV uno AUDISON

What is the POD technology in the Audison AV uno?

The POD (Power On Demand) technology combines the audio quality of Class AB with the efficiency of Class D amplifiers, providing high power and low distortion.

How do I connect the power cables to the AV uno?

Connect the positive cable to the Power (11-15V DC) terminal and the negative cable to the Power (Ground) terminal. Use cables up to 2 AWG for maximum current transfer. Ensure the ground point is clean metal for continuity.

Can I use the AV uno as a dual mono amplifier?

Yes, use two AV uno amplifiers for Dual Mono operation. Each amplifier drives a single channel, with separate inputs and outputs. Connect the source to each amp’s Pre In and adjust settings independently.

How do I set the low-pass filter on the AV uno?

Set the PASS MODE switch to LO. Then adjust the LO PASS knob from 50 to 150 Hz to set the cutoff frequency. This is typically used for subwoofers.

What is the purpose of the AV bit IN module?

The AV bit IN is a digital interface that allows seamless connection to bit Ten D or bit One processors via AD Link/AC Link. It enables digital signal transmission directly to the amplifier’s D/A converters for superior audio quality.

How do I replace the fuse on the AV uno?

Remove the faulty 100A AFS type fuse from the rear panel and replace it with the spare provided. Ensure the amplifier is off and the power cable is disconnected before replacing.

What does the THERMAL LED indicate?

The red THERMAL LED flashes at 60°C (power limited by 1.5 dB), increases flashing at 70°C (3 dB limit), and stays on at 80°C (thermal protection). The amplifier restarts when it cools to about 70°C.

Can I use the AV uno without a remote turn-on wire?

Yes, set the ART switch to ON if your source lacks a 12V remote output. The amplifier will turn on automatically when it detects a signal on the SPK IN high-level inputs.

What is the maximum power output of the AV uno at 1 ohm?

At 14.4V and 1% THD, the AV uno delivers 1700W x 1 at 1 ohm. However, the minimum recommended load impedance is 1 ohm; lower loads may trigger protection.

How do I clean and maintain the AV uno amplifier?

Clean the amplifier with a damp cloth (water and mild soap) then dry. Remove dust from the heat sink fins using a soft cloth or vacuum. Do not use compressed air, as it can push debris inside. Ensure good ventilation around the amplifier.

1. INTRODUCTION

Coming directly from the know-how of the exceptional Thesis line, Voce components take 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 uno AMPLIFIER PROJECT

AV uno is an amplifier featuring an innovative circuitry called POD (Power On Demand). It allows to combine the plus points, in terms of audio quality and robustness, of the AB Class traditional amplifiers with the efficiency of the D Class amplifiers.

AV uno is a mono amplifier designed to drive the subwoofer but also suitable for high power Dual Mono systems. Power, control and outstanding final stages are capable to unbelievable bass and extraordinary musical quality on the whole frequency range. AV uno also allows you to replace the analog input board with the digital one (AV bit IN).

3. SAFE SOUND

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:

• 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.

9. ACCESSORIES: AV BIT IN

Digital interface for all AV amplifiers. It allows a seamless digital connection with bit One and bit Ten D processors via the AD Link/AC Link connection.

By inserting the AV bit IN "Digital Interface" into AV amplifiers, the digital signal in S/PDIF format, through the AD Link connection, leads directly to the high-quality internal D/A converters. After that, the signal becomes analog and is immediately amplified protecting it from deterioration over long distances. The result is high-quality music not reachable with any other analog system.

AV bit IN ASC is the management interface, programmed to control all amplifier functions. The user can interact with the microprocessor which, without interfering with the sound, will adjust all possible settings. This section is dedicated to all those who want to exploit the unique features of this product.

Some functions are automatic and transparent to the user, while others require intervention during installation and calibration or modification. Accessing ASC you will find a series of menus that will list all the specific entries on which you can intervene.

9.1 HOW TO INSERT AV BIT IN

WARNING: In particularly severe conditions the amplifier can reach temperatures between 80 and 90°C (176 ÷ 194°F). Make sure the temperature is not dangerous before touching it.

9.2 FRONT PANEL

1. AD Link: Digital audio bus that can transmit the signal of 8 channels. It exploits a Class 5 or 6 shielded cable for Ethernet networks normally used in computer networks.

AD Link IN: RJ-45 input terminal to connect a digital signal coming from other AV amplifiers or other external devices equipped with AD Link (bit One / bit Ten D).

AD Link OUT: RJ-45 terminal output for connection to external devices capable of receiving the AD Link digital signal (AV / TH amplifiers).

1. AC Link: It is composed of a digital bus and control signals for the management of the functions of the device to which it is connected. It provides the ability to build a digital network interacting with other devices provided with AC Link such as AV / TH amplifiers and digital audio processors. The RJ-12 terminated cable is a 6-pin cable, like the one normally used for digital telephone purposes, but it is not compatible with digital telephone technology.

AC Link IN: RJ-12 input terminal for connection to the processor or other devices located upstream of the system (see 9.4).

AC Link OUT: RJ-12 input terminal for connection to the processor or other devices located downstream of the system (see 9.4).

The AC Link connection is able to provide power to the external device.

AC Link-Remote IN: If an amplifier provided with AV bit IN is connected to bit Ten D processor, the amplifier can be turned on via the processor, without the use of the amplifier Remote-In.

If another processor is used (bit One) or if there is a Thesis TH amplifier in the AC Link chain, the Remote-In function on the AC Link won't be available.

If in the AC Link chain there is an amplifier different from the AVs (Thesis TH), the Remote-In function on the AC Link has to be disabled. Set the AV bit IN AC Link Turn ON jumper to OFF as shown in the image below.

WARNING: for AC Link / AD Link connections, only use the cables supplied with the products. Important: adjust the amplifier volumes to position 1 (5V RMS) when using the AV bit IN module.

9.5 HOW TO CONFIGURE AV bit IN

Before starting the configuration of the amplifier or amplifiers equipped with an AV bit IN digital input module, set and finalize the processor (bit Ten D / bit One) that will interface with the system.

The processor channels specialized in "Digital output / AC Link - AD Link" will interface with the amplifiers equipped with the AV bit IN input module, as shown in the following procedure. In the "CHANNEL MAP" of the bit Ten D PC software, the specialized channel with digital output are highlighted in green, while for the bit One it should be written down which output channels are assigned the digital format (AD Link - AC Link) during the "I/O Configuration Wizard".

Set the processor overall volume at a level of -45 dB, which does not endanger the system speakers during installation / adjustment.

Before starting to configure the AV bit IN module and after setting the processor (bit Ten D / bit One), turn the sound system off and then on again using the DRC SRC knob.
