• 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.

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

TECHNOLOGIES

**DYNAMIC THERMAL MANAGEMENT DTM***
OUR PATENTED DTM TECHNOLOGY PROVIDES A FASTER HEAT EXCHANGE BETWEEN THE ELECTRONIC cOMPONENTS AND THE HEATSINK, INCREASING THE EFFICIENCY OF OUR AMPLIFIERS AND RESULTING IN LOWER DISTORTION LEVELS DURING LONG PLAYING TIME

VIBRATION ABSORPTiON DEVICE VAD
OUR VAD” TECHNOLOGY REDUCES ALL IMPACT 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 IN A COMPACT CHASSIS, PROVIDING FLEXIBLE

INSTALLATION SOLUTIONS FOR VEHICLES WITH LIMITED SPACE.

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.

AUDIO INPUTS

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 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 headunit 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.

SD RLC / GAIN SETTING

Gain setting
Necessary equipment:

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

Set up procedure

• Turn the gain control all the way Ø 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.
• Set the source unit’s fader control to center position;
• Set the variable “LOW” crossover in 500Hz and the “SUBSONIC” in 5Hz;
• Use a 60 Hz 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 its correct voltage output, turn off the source unit and reconnect the speaker(s)

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.

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. 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 40Hz (“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 and select the “LP” key in position “ON”;
