DEAR CUSTOMER,
CONGRATULATIONS ON ACQUIRING A PRODUCT WITH THE HIGHEST
QUALITY AND TECHNOLOGY!
You have just purchased a SounDigital product of the highest technology and quality,
so we thank you for your confidence.
Class D Amplifiers:
Class D amplifiers have as main characteristics the audio quality, efficiency,
application versatility and compact design. Following are the advantages of these
features:
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 superior Class AB performance.
Efficiency – SounDigital Class D amplifiers have total efficiency (output + power
source) greater than 70%, which guarantees lower battery consumption and less
heating.
Application Versatility – The flat full-frequency response of SounDigital amplifiers
allows them to be used in all car sound systems. Meeting the demands with extreme
quality.
Compact Design – The high efficiency and high technology applied, allows
SounDigital amplifiers to be very compact, facilitating installation in vehicles where
space is limited.

The design of the EVOX line of amplifiers aims to give users the feeling of the smooth
and deep bass, without compromise! Our Low Bass Correction technology compares
the input signals to the amplifier against the output after the amplification stage, making
real time correction of the signal, delivering a deeper bass with less distortion.

INSTALLATION SEQUENCE
10
ØMount the amplifier in such a way you have access to the connectors;
ØInstall the power cables in the vehicle properly, starting from the battery to the fuse holder
or circuit breaker, use the cable with the appropriate size. Make all connections, install fuse
holders or circuit breakers, but without placing the fuses or with the circuit breakers in the
"OFF" position;
ØConnect the power cables in to the amplifier, observing the polarity. Connect all the positive
cables from the fuse holder or circuit breaker to the positive conector of the amplifier (+)
and all the negative power cables from the batteries to the negative connector of the
amplifier;
ØThe ground cable must be as short as possible and must be connected to the vehicle
chassis and the battery negative;
ØInstall the signal input cables in a proper way, distant from the power cables;
ØConnect the RCA or the high level signal input cables to the head unit and amplifiers;
ØInstall the audio output cables with the appropriate section, distant from the power and
audio input cables;
ØConnect the audio output cables to the amplifier and speakers respecting the positive (+)
and negative (-) polarities;
ØInstall the remote cable with the power cables, using 1.5mm² (15 AWG) cable or thicker;
ØConnect the remote power cable to the amplifier's "REM" terminal at the main unit's remote
power output (when not using the high level signal inputs);
ØBefore powering the system, verify all the connections and make sure there are no
mistakes or short-circuits on the power and ground cables;
Ø;Reconnect the ground of the batteries
ØCheck if the head unit is turned off and then place the fuses in the fuse holders or switch the
circuit breakers on;
ØTurn on the main unit and the amplifier will turn on the "POWER ON" LED indicating that it is
in operation.
Remove the paint
between the terminal
and chassis
THE MAXIMUM DISTANCE FOR THE INSTALLATION OF THE FUSE/CIRCUIT BREAKER
IS 12 INCHES (30cm) AWAY FROM THE BATTERY.
BEFORE PROCEEDING WITH THE INSTALLATION, UNPLUG THE NEGATIVE TERMINAL
FROM ALL OF THE BATTERIES, TO AVOID FIRE, DAMAGE TO THE AMPLIFIER AND THE
USER HIMSELF.

ELECTRICAL DIMENSIONING AND AUDIO INPUTS
ELECTRICAL DIMENSIONING
11
For proper operation of your SounDigital amplifier, you need the proper
dimensioning of the electrical system and the cables used.
The table below shows the minimum section of GND cables, +12VDC cables
and speaker output cables according to the power generated by the amplifier.
We recommend the use of only OFC (Oxygen Free Copper) cables on the
installation of our products.
Copper-clad aluminum wire (CCAW) must not be used.

High level input must be used when the main unit does not have RCA outputs.
When High level input is used, no remote connection is required, the amplifier
recognizes the audio signal and switches on.
If your source unit is not able to turn on the amplifier through the High level input,
the remote input should be connected normally.
RCA AND HIGH LEVEL INPUTS SHOULD NOT BE USED SIMULTANEOUSLY OR
YOU MAY DAMAGE THE AMPLIFIER.

Using Bass Boost
The Amplifier Bass Boost setting enables the user to boost the sound intensity at low
frequencies of the sound system, where boost intensity can be adjusted.
This is a semi-parametric equalizer type circuit with ''Q'' value for the fixed filter, with an
intensity boost adjustment from 0 to +12dB (16 times), and a central frequency
adjustment of the filter in 50Hz, making it versatile for several types of sound systems.
How to Adjust Bass Boost
How to Adjust the Crossovers
Reproduce your favorite song and set the boost
intensity between 0dB and +12dB at the variable
control level according your preference.
The use of the two associated filters can form a
bandpass filter, as in the figure below, where the
point "A" is defined in the "SUBSONIC" crossover
and the point "B" is defined in the "LOW" crossover.
To set the "SUBSONIC" variable control between 5Hz and 30Hz ("A") where you want
to perform the high pass cut filter;
Set in the "LOW" variable control between 50Hz and 500Hz ("B") where you want to
perform the low pass cut filter;

BATTERY CONNECTION DIAGRAM
When necessary the association of one or more battery banks to supply the
necessary current to the amplifier, it is recommended to use batteries of the same
brand, model, and if possible the same manufacturing lot so that the system has
the maximum performance.
For an ideal energy performance, we recommend that all batteries be connected to
positive and negative busbars and the busbars connected to the amplifier, as
shown in the diagram below:

1
Battery connections without the use of a busbar,
as shown in the example below, must be avoided.
This setting decreases the efficiency of supplying
power to the system.
All cables, positive and negative,
connected from the battery to the
busbar must be the same length.
Likewise the cables connected from
the busbar to the amplifier.
