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/vessel audio installation;
Before proceeding with the installation of any electric equipment on your vehicle/vessel, 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 DC voltage batteries between 12.6 and 14.4 volts. Before installing the equipment, check voltage of the batteries; Choose a ventilated place to install the amplifier ;
Mount the amplifier in a secure way. Avoid mounting it on metallic parts of the vehicle/vessel, 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/vessel;
Please select a dry location to mount your amplifier. The products are designed to operate in humid environments but the direct contact with water can damage the amplifier.
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/vessel. Make sure you are not making holes in the fuel tank, brake lines, boat hull or electrical cables of the vehicle/vessel;
Make sure the cables are properly secured throughout the installation; Wear gloves, safety glasses and and all necessary PPE during the installation of Sound Digital amplifiers.

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 MENAGEMENT – DTM

The **DTM*** is a dynamic thermal management system which always maintains a high efficiency of the amplifier by accelerating the thermal exchange of electronic components with the heatsink

• Patent. Required
  ULTRA COMPACT PCB
  An intelligent layout, with great use of the PCB area and the use of modern components with reduced structure guarantee Sound Digital products a compact design, at the same time robust and with excellent thermal efficiency.
  ROBUSTA CONSTRUCTION
  Thinking about the application of power sports, the product has an extremely robust assembly, both the correction points and the layout of the plate were designed to withstand high vibrations, bumps and impacts.

TECHNOLOGIES

Sound Digital added a new device to the EVOPS products which act like shock absorbers reducing the impact of vibration on the electronic circuit board, thereby increasing the life and reliability of the amplifiers.

1 POWER SUPPLY
Soun Digital amplifiers are known for their low consumption of battery, and this feature was improved on the EVOPS Line. The new I-POWER SUPPLY is even more modern, which replaces the old toroidal transformers by a new generation of “EE” core
transformers delivers efficiency above 90% ,ensuring more hours of sound without battery recharge.
Efficiency measured at power supply only

MARINIZATION WITH PROTECTION INDEX IP64
The product is protected against ingress of dust particles and water droplets from all sides, beyond that, the plate receives a conformal coating treatment to protect the components from moisture.

ELECTRICAL DIMENSIONING AND AUDIO INPUTS

ELECTRICAL DIMENSIONING

For proper operation of your Soun Digital 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.

1200 warms| POWER CABLE
GROUND CABLE| 16mm² – 5 AWG
---|---|---
SPEAKER CABLE| 2x2mm² 12 AWG

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/vessel 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 MAX: DISTANCE FOR THE INSTALLATION OF THE FUSE/CIRCUIT BREAKER IS ONE FOOT (30 CM) 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 connector 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 negative connector of battery or vehicle chassis in case of metallic chassis;
➢ 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;
➢ 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 headhunt 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
➢ Necessary equipment:
➢ Digital AC voltmeter;
➢ Media with sine wave test tone 60Hz recorded at 0db;
➢ Screwdriver 1/8″ ( for gain set)

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.
➢ Set the source unit’s 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)
