SAFETY INSTRUCTIONS
THIS "WARNING" SIGN ALERTS THE USER OF IMPORTANT INFO. NOT FOLLOWING
THIS INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR DAMAGE TO THE
EQUIPMENT.
Warning!
To prevent injuries to the user or damage to the amplifier, read all safety instructions
written on this manual;
If you are insecure about the installation of this equipment, get in touch with our
tech support or with a professional specialized in car audio installation;
Before proceeding with the installation of any electric equipment on your vehicle,
unplug the negative (-) terminal of the battery to avoid fires, injuries or damages;
Use your sound system safely. The continuous exposure to sound pressures over
85dB may cause irreversible hearing damage;
This equipment is for use in automotive DC voltage batteries between 12.6 and
14.4 volts. Before installing the equipment, check voltage of the batteries;
Do not install the amplifier in places exposed to water, dirt or humidity;
Choose a ventilated place to install the amplifier and avoid blocking the side
ventilation windows;
Mount the amplifier in a secure way. Avoid mounting it on metallic parts of the
vehicle, because it may cause ground looping (noise);
Make sure that the location chosen for the amplifier installation does not effect the
operation of the vehicle;
When passing cables through metallic walls, use rubber O-rings to avoid cable
cutting and short-circuits.
Clean the amplifier periodically with brush or dry cloth to assure the thermal
efficiency of the heatsink.
This product may reach temperatures over 60°C/140°F. Make sure it is cold before
touching it;
Be careful when making holes in the vehicle. Make sure you are not making holes
in the fuel tank, brake lines or electrical cables of the vehicle
Make sure the cables are properly secured throughout the installation;
Wear gloves, safety glasses and and all necessary PPE during the installation of
SounDigital amplifiers.

TECHNOLOGIES
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
ULTRA COMPACT PCB
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.

6
TECHNOLOGIES
VIBRATION ABSORPTION DEVICE
*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.
I - POWER SUPPLY
SounDigital added a new device to the EVO X products which act like springs,
reducing the impact of vibration on the eletronic circuit board, thereby increasing
the life and reliability of the amplifiers.

DISASSEMBLING OF THE PLASTIC COVER
ASSEMBLING THE PLASTIC COVER
The plastic covers have the function of finishing and hiding the amplifier fixing
screws. To disassembling and assembling them, follow the instructions below.
1. Carefully pull out the top of plastic cover to release the upside latches, as shown in the picture 1.
2. Slide up the plastic cover in a continuous movement to remove it.
1. To fit the plastic cover back, carefully insert the point A of the plastic cover into point B of the
amplifier, slowly sliding it down.
2. Gently press the top of the plastic cover towards the bottom of the amplifier until 3
you hear a «click» noise.

ELECTRICAL DIMENSIONING AND AUDIO INPUTS
ELECTRICAL DIMENSIONING
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.
RCA INPUTS

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 cable to the head unit and the amplifier;
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 ;
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 headunit is turned off and then place the fuses in the fuse holders or switch
the circuit breakers on;
ØTurn on the headunit and the amplifier will turn on the "On" LED indicating that it is in
operation.

ØMedia with sine wave test tone 60Hz
recorded at 0db;
ØScrewdriver 1/8" ( for gain set)
Set up procedure
Turn the gain control all the way
Ø
down.
ØDisconnect the output cables from
the amplifier outputs;
ØTurn off all processing (bass, treble,
loudness, EQ, etc.);
ØSet the source unit volume to 3/4 of
full volume.
ØSet the source unit's fader control to
center position;
ØSet the variable "LOW" crossover in
500Hz and the "SUBSONIC" in 5Hz;
Ø Use a 60 Hz sine wave
ØIncrease the gain control until the
"CLIP" LED starts blinking;
ØReturn the gain to the limit where
the "CLIP" LED stops blinking and
remains off;
ØOnce y o u have adjusted the
amplifier to its correct voltage
output, turn off the source unit and
reconnect the speaker(s)

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.
