SAFETY INSTRUCTIONS
To avoid injury to the user or damage to the amplifier, read all safety
instructions written in this manual.
Warning
THIS “WARNING” SIGN ALERTS THE USER OF IMPORTANT INFO. NOT FOLLOWING THESE
INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR DAMAGE TO THE EQUIPMENT.
DYNAMIC THERMAL MANAGEMENT – DTM
The DTM is a dynamic thermal recovery system that 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, guarantees SounDigital products a compact
design that, 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 battery consumption, 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 deliver 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 ® impacts 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 brings both high performance and
power to a compact chassis, providing flexible installation solutions for
vehicles with limited space.
FULL RANGE
The 400.4 EVOPS amplifier is a versatile product that covers the entire
audible frequency range, any type of loudspeaker or music program.
MARINIZATION WITH PROTECTION INDEX IP64 REDUCED SIZE
The product is protected against ingress of dust particles and water droplets
from all sides, beyond that, the PCB receives a conformal coating treatment to
protect the components from moisture.
DISASSEMBLING THE PLASTIC SEALS
- Squeeze the assembled Flexible Plastics Seals;
- Pull out the plastic seals.
Merely illustrative images.
ASSEMBLING THE PLASTIC SEALS
- Hold the disassembled Flexible Plastics Seals and fit them in their specific housing;
- Each connector has its specific Plastic Seal;
- Make sure the Flexible Plastics Seals are perfectly fitted.
Merely illustrative images.
Audio inputs and controls
Power inputs and audio outputs
BEFORE PROCEEDING WITH THE INSTALLATION, UNPLUG THE NEGATIVE TERMINAL FROM ALL OF THE BATTERIES, TO AVOID FIRE, DAMAGE TO THE AMPLIFIER, AND THE Warning! 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, and install fuse holders or circuit breakers, but without placing the fuses or with the circuit breakers in the “OFF” position;
- THE MAXIMUM DISTANCE FOR THE INSTALLATION OF THE FUSE/CIRCUIT BREAKER IS 12 INCHES (30cm) AWAY FROM THE BATTERY.
Warning!
- Connect the power cables 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 the 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 1.5mm (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.
Warning!
Minimum recommended installation distance between amplifiers. 1.18in
(30mmFor installations with more than one amplifier, a second unit is not
included. Merely illustrative images.
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 for the installation of our products. Copper-clad aluminum wire (CCAW) must not be used.
AUDIO INPUTS
RCA inputs
- “HP” Set variable control in High Pass function.
- “F” Set variable control in Full Range function;
- “LP” Set variable control in Low Pass function;
- Change the switch to the “F” position (Full Range) – All the frequencies will he reproduce shown in the grant?
Change the switch to the “HP” position – Set in the variable control between 45Hz and 850Hz (“A”) where you want to perform the high pass cut filter; Change the switch to the “LP” position – Set in the variable control between 45Hz and 850Hz (“B”) where you want to perform the low pass cut filter.

GAIN SETTING
Necessary equipment
- 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 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).

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:
TECHNICAL SPECS
- It is mandatory to install the fuse at a maximum distance of 12 inches from the battery.
- Power at 14.4V @ 60Hz with a maximum THD of 1%.
- “POWER RATING ACCORDING TO CTA-2006 INDUSTRY STANDARDS.
