INTRODUCTION

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 – Soun Digital 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

LOW BASS CORRECTION
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.

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

ROBUST CONSTRUCTION
Thinking about the application of power sports, the product has an extremely robust assembly, both the fixing points and the layout of the PCB were designed to withstand high vibrations, bumps and impacts

VIBRATION ABSORPTION ® DEVICE – VAD
Our Technology reduces all impact ® VAD caused by vibration on the electronic circuit board. This can include road vibration and even vibration caused by sound waves, increasing the reliability of our amplifiers.

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.

I-POWER SUPPLY
SounDigital amplifiers are known for their low consumption of battery, and this feature was imp r o ve d o n t h e E VOX Li n e . T h e n e w I-POWER SUPPLY is even more modern, which r e p l a c e s t h e o l d t o r o i d a l t r a n s f o rme r s by a new generation of “E-E” core tran sformers delivers efficiency above 90%*, ensuring more hours of sound without battery recharge.

ASSEMBLING AND DISASSEMBLING 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.

DISASSEMBLING OF THE PLASTIC COVER

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.
   

*Merely illustrative images.

ASSEMBLING THE PLASTIC COVER

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 sides of the top of the plastic cover towards the bottom of the amplifier until you hear a clicking noise

INSTALLATION SEQUENCE

Warning!
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,

• Mount the amplifier in such a way you have access to the connectors;
• Install 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.

Warning
THE MAXIMUM DISTANCE FOR THE INSTALLATION OF THE FUSE/CIRCUIT BREAKER IS 12 INCHES (30cm) AWAY FROM THE BATTERY.

• Connect 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;

• The ground cable must be as short as possible and must be connected to the vehicle chassis and the battery negative;
  

• Install the signal input cables in a proper way, distant from the power cables;

• Connect the RCA or the high level signal input cables to the head unit and amplifiers;

• Install the audio output cables with the appropriate section, distant from the power and audio input cables;

• Connect the audio output cables to the amplifier and speakers respecting the positive (+) and negative (-) polarities;

• Install the remote cable with the power cables, using 1.5mm² (15 AWG) cable or thicker;

• Connect 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);

• Before powering the system, verify all the connections and make sure there are no mistakes or short-circuits on the power and ground cables;

• Reconnect the ground of the batteries;

• Check if the head unit is turned off and then place the fuses in the fuse holders or switch the circuit breakers on;

• Turn on the main unit and the amplifier will turn on the “ON” LED indicating that it is in operation.

GAIN SETING

GAIN SETTING
Necessary equipament:

• Digital AC voltmeter;
• Media with sine wave test tone 60Hz recorded at 0dB;
• Screwdriver 1/8″ ( for gain set);

Set up procedure

• Turn the gain control all the way down;
• Disconnect the output cables from the amplifier outputs;
• Turn off all processing (bass, treble,loudness, EQ, etc.);
• Set the source unit volume to 3/4 of full volume;
• On the CD player, set the fader control to center position;
• Set the variable “LOW” crossover in 500Hz and the “HIGH” in 3Hz;
• Use a 60Hz sine wave;
• Increase the gain control until the “CLIP” LED starts blinking;
• Return the gain to the limit where the “CLIP” LED stops blinking and remains off;
• Once you have adjusted the amplifier to the correct voltage output, turn off the source unit and reconnect the speaker(s).

CROSSOVER AND BASS BOOST SET UP

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 typesof sound systems.

How to Adjust Bass Boost
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.

**How to Adjust the Crossovers

** Set in the “HIGH” variable control between 3Hz and 30Hz (“A”) where you want to perform the subsonic cut filter;

Set in the “LOW” variable control between 50Hz and 500Hz (“B”) where you want to perform the low pass cut filter;
