PANELS DESCRIPTION

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 BREAKERIS 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.

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.

AUDIO INPUTS

RCA inputs

High level signal inputs

• 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 LEVEL INPUTS SHOULD NOT BE USED SIMULTANEOUSLY OR YOU MAY DAMAGE THE AMPLIFIER

WIRING DIAGRAM

WARNING: Unplug the negative (-) terminal of the battery before proceeding with any eletrical installation in the vehicle to avoid fire starts, wounds or damage to the amplifier

POWER CONNECTIONS

AUDIO INPUT AND OUTPUT CONNECTIONS

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

• Ø Digital AC voltmeter;
• Ø Media with sine wave test tone 60Hz recorded at 0dB;
• Ø 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 audio player, set the fader control to center position;

• Set the variable “LOW PASS” cr o ss o ver i n 6 k H z a n d t h e “SUBSONIC” in 5Hz;

• 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).

BASS BOOST AND CROSSOVER SETUP

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
The use of the two associated filters can form a bandpass filter, as in the figure below, where the point “A” is defined in the “SUBSONIC” crossover and the point “B” is defined in the “LOW PASS” crossover.

To set the “SUBSONIC” variable control between 5Hz and 40Hz (“A”) where you want to perform the subsonic cut filter

Set in the “LOW PASS” variable control between 50Hz and 6kHz (“B”) where you want to perform the low pass cut filter;

TECHNICAL SPECS

• It is mandatory to install the fuse at a maximum distance of 12 inches from the batter
• Power at 14.4V @ 60Hz with a maximum THD of 1
