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 – 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.

THIS “WARNING” SIGN ALERTS THE USER OF IMPORTANT INFO. NOT FOLLOWING THIS INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR DAMAGE TO THE EQUIPMENT.

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.

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

Warning: All RCA Inputs must be connected for the all channels to work properly. If the signal source is mono type, use “Y” cable at the input.

High Level input

Warning: All High Level Inputs must be connected for the all channels to work properly.

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

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.

Warning: All RCA Inputs must be connected for the all channels to work properly. If the signal source is mono type, use “Y” cable at the input.

SD RLC / GAIN SETTING

*EXTERNAL LEVEL CONTROL – SD RLC (NOT INCLUDED)**

The SD RLC is an easy-to-install external level control accessory that allows you to tune the level of SOUNDIGITAL amplifiers that have remote level control.
In SD RLC, you can adjust the amplifier level without having to lean over and adjust the gain setting on the amplifier and can monitor the “CLIP” LED which is also available on the accessory.

GAIN SETTING
Necessary equipament:

• Digital AC voltmeter;
• Media with sine wave test tone 60Hz recorded at 0db;

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 source unit volume to 3/4 of full volume;
• On the CD player, set the fader control to center position;
• Set the LP switch key in “OFF”;
• 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).

BASS BOOST AND CROSSOVER 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.
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 in 50Hz, making it versatile for several types of sound systems.

How to Adjust Bass Boost
Reproduce your favorite song and set the boost intensity between 0dB and +12dB at the variable control level according your preference.
How to Adjust the Crossovers
For full range application, select the LP key in the “OFF” position and the “SUBSONIC” variable control at 5Hz. All frequencies will be reproduced according to figure bellow;

To set the “SUBSONIC” variable control between 5Hz and 80Hz (“A”) where you want to perform the subsonic cut filter;

Set in the “LOW” variable control between 50Hz and 1kHz (“B”) where you want to perform the low pass cut filter and select the “LP” key in position “ON”;

TECHNICAL SPECS

• It is mandatory to install the fuse at a maximum distance of 12 inches from the battery.
• Power at 12.6V @ 60Hz with a maximum THD of 1%.
