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 installation distance between amplifiers*. 1.18in (30mm)

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.
Copper-clad aluminum wire (CCAW) must not be used.

AUDIO INPUTS

• RCA inputs

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 source unit and reconnect the speaker(s).

CROSSOVER SET UP

• Change the switch to “F” position (Full Range) – All the frequencies will be reproduced as in “Figure 1”;
• Change the switch to “HP” position (High Pass) – All frequencies above 80Hz will be reproduced as in “Figure 2”;
• Change the switch to “LP” position (Low Pass) – All frequencies below 80Hz will be reproduced as in “Figure 3”.

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:
