TECHNOLOGIES

DYNAMIC THERMAL MANAGEMENT – DTM

The DTM is a dynamic thermal recovery system which always maintains a high efficiency of the amplifier by accelerating the thermal exchange of electronic components with the heatsink.
Patent required.

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.

I-POWER SUPPLY

SounDigital amplifiers are known for their low  consumption of battery, and this feature was improved on the EVOX2 Line. The new I-POWER SUPPLY is even more modern, which replaces the old to roid altrans formers by a new generation of “E-E” core transformers delivers efficiency above 90%*, ensuring more hours of sound without battery recharge.

*Efficiency measured at power supply only.

VIBRATION ABSORPTION ® SYSTEM – VAS

Our Technology reduces all impact ® VAS 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 5.8″ 4.4″

The technology used in our amplifiers bring both high performance and power into a compact chassis, providing flexible installation solutions for vehicles with limited space.

FULL RANGE

The 800.4 EVOX2 amplifier is a versatile product that cover the entire audible frequency range, any type of loudspeaker or music program

ASSEMBLING AND DISASSEMBLING THE PLASTIC COVER

The plastic covers are used to finish off and hide the amplifier’s fixing screws. To disassemble and assemble them, follow the instructions below.

DISASSEMBLING OF THE PLASTIC COVER

1. 1. Carefully pull out the top of the plastic cover to release the upside latches, as shown in 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.

• Fix the amplifier so that the connectors can be easily accessed;
• 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 “POWER ON” LED indicating that it is in operation.

Warning
Minimum recommended i n stal lati o n d ista n ce between amplifiers*. 1.18in. (30mm)

*For installations with more than one amplifier, second unit not included. Merely illustrative images.

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.

800 WRMS| POWER CABLE (+12VDC)
GROUND CABLE (GND)| 10mm² (7 AWG)
---|---|---
SPEAKER CABLE| 2 x 1.5mm² (15 AWG)

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.

AUDIO INPUTS

RCA inputs

All RCA inputs must be connected for the amplifier to work properly. If the signal source is mono type, use “Y” cable at the input.

High level signal inputs

All High level signal inputs must beconnected for the amplifier to work properly.
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.

Warning
RCA AND HIGH LEVEL INPUTS SHOULD NOT BE USED SIMULTANEOUSLY OR YOU MAY DAMAGE THE AMPLIFIER.

GAIN SETTING

Necessary equipament:

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

Set up procedure

• This procedure is the same for both gain controls;
• 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 audio player volume to 3/4 of full volume;
• Set the audio player fader control to center position (left and right fader controls);
• Set the crossover selector switch in “F”;
• Use a 60 Hz sine wave;
• Connect the AC voltmeter to the speaker output connectors of the amplifier. Make sure you test the voltage at the correct connectors (+ and –);
• Increase the gain control until the target voltage is observed with the voltmeter (see the chart below);
• Once you have adjusted the amplifier to the correct voltage output, turn off the so urceun it and reconnect t h e speaker(s).

“HP” Set variable control in High Pass function.

• Change the switch to “F” position (Full Range) – All the frequencies will be reproduced.
  

• Change the switch to “HP” position – Set in the variable control between 45Hz and 850Hz (“A”) where you want to perform the high pass cut filter;
  

• Change the switch to “LP” position – Set in the variable control between 45Hz and 850Hz (“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:

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.

TECHNICAL SPECIFICATIONS

*It is mandatory to install the fuse at a maximum distance of 12 inches from the battery.

**Power at 14.4V @ 60Hz with a maximum THD of 1%.

**POWER RATING ACCORDING TO CTA-2006 INDUSTRY STANDARDS
