User Manual

INTRODUCTION

Dear Costumers,
Congratulations for purchasing a product of the highest quality and technology!
SounDigital’s products are developed to ensure maximum efficiency and reliability in your audio system.
Class D Amplifiers:
Class D amplifiers have audio quality, efficiency, application versatility, and compact design as their main features. Here are the advantages of these characteristics:
Audio Quality – In the past, Class D products had limited response and for higher frequencies, Class AB products performed better, but their efficiency was very low.
The new technologies introduced by SounDigital resulted in a Class D amplifier with high efficiency and performance superior to Class AB.
Efficiency – SounDigital Class D amplifiers have a total efficiency (Output + Source) higher than 70%, which ensures lower battery consumption and less heating.
The versatility of Application – The flat response in all frequencies of the SounDigital amplifiers allows them to be used in all automotive sound systems. They meet the demands with extreme quality.
Compact Design – The high efficiency and high technology applied to allow SounDigital amplifiers to be very compact, facilitating installation in vehicles where space is limited.
IMPORTANT INFORMATION
Read this manual carefully and follow precisely all the information contained herein, which are very important and allow your amplifier to work optimally. If you think it necessary, do not hesitate to contact our technical support by e-mail at [email protected] or by SAC +55 (51) 3042-9001.

SAFETY INSTRUCTIONS

To prevent injury to the user or damage to the amplifier, read all the safety instructions contained in this manual;
If you feel insecure about installing the equipment, contact SounDigital technical support or a qualified professional in automotive sound installation;
Before proceeding with the installation of any electrical equipment in the vehicle, disconnect the negative (-) terminal of the battery to avoid fire, injury or damage to the amplifier;
Use your sound system safely, continuous exposure to sound pressures above 85 decibels may cause irreversible hearing damage;
This equipment is for use with automotive batteries of DC voltage between 12.6 and 14.4 volts. Before installing the equipment, check the voltage of the batteries;
Do not install the amplifier in the engine compartment or in places exposed to water, humidity, dust or dirt;
Install the amplifier in a ventilated place and prevent the side ventilation windows from being obstructed;
Fix the amplifier in a proper and firm manner. Avoid the fixation on metallic parts, as this procedure may cause ground “Looping” (noise);
Use rubber “O-rings” when passing the wires in metallic walls in order to prevent them from being cut and causing short-circuit;
Make sure that the place chosen for the installation of the amplifier does not hinder the operation of the vehicle;
During the use of this product, the aluminum housing/dissipator may reach temperatures higher than 60°C. Before touching the amplifier, be sure that it is cold;
To maintain the efficient thermal dissipation, periodically clean the dissipator, removing dust and impurities with the help of a brush and/or dry cloth;
Be very careful when drilling holes in the vehicle, make sure not to pierce the fuel tank, brake lines, electrical cables, etc;
Make sure that all cables are properly secured throughout the entire installation;
Wear gloves, safety goggles, and all necessary safety equipment during the installation of the SounDigital amplifiers.

This symbol alerts the user to the presence of important instructions.
Failure to comply with these instructions may result in damage to the amplifier or the user.

ASSEMBLING AND DISASSEMBLING THE PLASTIC COVER

The plastic covers have the function of giving finishing and hiding the amplifier’s fixation screws. To remove and replace them, follow the instructions below.

DISASSEMBLING THE COVER

ELECTRICAL SIZING AND AUDIO INPUTS

ELECTRICAL SIZING
For the correct operation of your SounDigital amplifier, it is necessary to properly size the electrical system and the cables used.
In the table below you can determine the minimum proper section of the grounding, positive + 12VDC, and audio output cables according to the amplifier power.

2000
WRMS| POSITIVE CABLE (+12VDC)
NEGATIVE CABLE  (GND)| 21mm² – 4 AWG
---|---|---
AUDIO OUTPUT CABLE| 2 x 2mm² – 12 AWG

For the connections from the battery to the amplifier and to the ground, use good quality copper cables.
CCA cables should not be used.

AUDIO INPUT
RCA Entry

All RCA inputs must be connected for all 4 channels to work.

INSTALLATION SEQUENCE

BEFORE INSTALLING ANY ELECTRICAL EQUIPMENT IN THE VEHICLE, DISCONNECT THE NEGATIVE (-) TERMINAL OF THE BATTERY TO AVOID FIRE, AND DAMAGE TO THE AMPLIFIER AND TO THE USER HIMSELF.

• Fix the amplifier so that there is access to the connectors.
• Install the power cables in the vehicle in a proper way, starting from the battery up to the fuse holder or circuit breaker, use the cable with the proper section. Make all connections, and install fuse holders or circuit breakers, but without placing the fuses or with the circuit breakers in the “off” position.

THE FUSE/PROTECTIVE CIRCUIT BREAKER MUST BE INSTALLED NO MORE THAN 30CM FROM THE BATTERY.

• Connect the power supply to the amplifier with the correct polarity. Connect all positive terminals (+) coming from the fuse holders or circuit breakers to the amplifier positive connectors, and all negative cables (GND) coming from the grounding point to the amplifier negative.
• The grounding should be as short as possible and should be connected to the vehicle chassis and the battery negative;

• Install the input signal cables properly, the input signal cables should be installed away from the power cables.
• Connect the RCA cables to the main unit and the amplifiers.
• Install the audio output cables, with the appropriate cross-section, in a proper manner and away from the power and audio input cables.
• Connect the audio output cables to the amplifier and speakers respecting the positive (+) and negative (-) polarities;
• Install next to the power cables the remote power cable with a section of 1.5mm² or larger.
• Connect the remote power cable to the “REM” terminal of the amplifier to the remote power the output of the main unit (when not using the high-level signal inputs);
• After the cable connections, before powering up the system, check that all connections are correct and that there are no shorts between cables and ground cables;
• Reconnect the battery ground;
• Make sure the main unit is off and then set the fuses or turn on the circuit breakers;
• Power up the main unit and the amplifier will turn on the “On” indicator LED indicating that it is operating.

GAIN ADJUSTMENT
Equipment required

• Voltmeter capable of measuring AC voltage;
• Media with 60Hz sinusoidal signal recorded at 0Db

Adjustment Procedure

• This procedure is the same for both gain controls;

• Set the gain control to a minimum;

• Disconnect the speakers from the amplifier output;

• Turn off or set to “0” all audio processing (bass, treble, loudness, EQ, etc.);
  Set the volume of the main unit to approximately 3/4 of the total. total.

• Set the audio positioning controls in the center (fader and left and right controls);

• Set the crossover to “F”;

• Play 60Hz media on the main unit

• Measure, with the aid of a voltmeter, the output voltage of the amplifier at the terminals where the speakers were connected;

• Turn the gain control clockwise until the voltage observed in the table below is reached;

• After adjustment, turn off the main unit and reconnect the speakers.
