User Manual
SD 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.
Cuidado
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
- Carefully pull the top flap outward, releasing the upper latches, as illustrated in the image.
- With one continuous movement, slide the plastic cover upward, removing it.
COVER ASSEMBLY
- Fit the plastic cover flush against the side of the amplifier, matching the attachment points A and B, and push it down.
- Lightly press the sides of the upper part of the plastic cover against the amplifier until you hear the “click” of the latches.

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
CUIDADO
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.
InØstall 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 command actions, install fuse holders or circuit
breakers, but without placing the fuses or with the circuit breakers in the
“off” position.
CUIDADO
THE FUSE/PROTECTIVE CIRCUIT BREAKER MUST BE INSTALLED NO MORE THAN 30CM FROM
THE BATTERY. CUIDADO! Øonnect 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 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;
connect 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.

Adjustment Procedure
The 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.
