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.

TECHNOLOGIES
*Efficiency measured at power supply only.
SounDigital amplifiers are known for their low
consumption of battery, and this feature was
improved on the EVOX Line. The new
I-POWER SUPPLY is even more modern,
which replaces the old toroidal transformers
by a new generation of "E-E" core transformers
delivers efficiency above 90%*, ensuring more
hours of sound without battery recharge.

TECHNOLOGIES
REDUCED SIZE
The technology used in our amplifiers
bring both high performance and
power a compact chassis, providing
flexible installation solutions for
vehicles with limited space.
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.
LOW BASS CORRECTION

An intelligent layout, with great use of
the PCB area and the use of modern
components with reduced structure
guarantee SounDigital products a
compact design, at the same time
robust and with excellent thermal
efficiency.

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.

Reproduce your favorite song and set the variable frequency control to the
frequency you want boost between 35Hz and 55Hz. Set boost intensity between
0dB and +12dB at the variable control Level.
CROSSOVER AND BASS BOOST SET UP
Set in the "HIGH" variable control between 3Hz 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;
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,
as well as the frequency of the region to be boosted, as indicated in the chart .
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 between 35 and 55Hz, making it versatile for
several types of sound systems.

WIRING DIAGRAM
Unplug the negative (-) terminal of the battery before proceeding
with any eletrical installation in the vehicle to avoid fire starts,
wounds or damage to the amplifier.
In case of connections with
more than one battery, see
the installation diagram on
page 15.

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:

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.
