SounDigital 400.2-EVO5 Amplifier Module

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.

SAFETY INSTRUCTIONS

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.

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.

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.

PANELS DESCRIPTION

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. CCA cables must not be used.

AUDIO INPUTS

RCA inputs

High Level input

High level input must be used when the main unit does not have RCA outputs.
When High level inputs 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 INPUTS SHOULD NOT BE USED SIMULTANEOUSLY OR YOU MAY Warning! DAMAGE THE AMPLIFIER.

INSTALLATION SEQUENCE

• 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;
• 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 SETTING

• Digital AC voltmeter;
• Media with sine wave test tone 60Hz recorded at 0db;
• 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 crossover selector switch in “F”;
• Use a 60Hz 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 its correct voltage output, turn off the source unit and reconnect the speaker(s).

“LP ” Frequencies below 80Hz will be reproduced “HP ” Frequencies above 80Hz will be reproduced

• Change the switch to “F” position (Full Range): All the frequencies are reproduced.

• Change the switch to “HP” position – All frequencies above 80Hz will be reproduced as in “Figure 2”;

• Change the switch to “LP” position – All frequencies below 80Hz will be reproduced as in “Figure 3”.
