TECHNOLOGIES

DYNAMIC THERMAL MANAGEMENT – DTM

The DTM is a dynamic thermal recovery 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 SounDigital products a compact design, at the same time robust and with excellent thermal efficiency.

ROBUST CONSTRUCTION
Thinking about the application of power sports, the product has an extremely robust assembly, both the fixing points and the layout of the PCB were designed to withstand high vibrations, bumps and impacts.

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

VIBRATION ABSORPTION SYSTEM – VAS
Our VAS 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 a compact chassis, providing flexible installation solutions for vehicles with limited space.

FULL RANGE
The 2400.1 EVOPS amplifier is a versatile product that cover the entire audible frequency range, any type of loudspeaker or music program.

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

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

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 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”;

• Set the audio player volume to 3/4 of full volume;
• On the audio player, set the fader control to center position;
• Set the “LP” switch to “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 the correct voltage output, turn off the source unit and reconnect the speaker(s).
