TECHNOLOGIES

DYNAMIC THERMAL MENAGEMENT – 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 Nondigital 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

Nondigital amplifiers are known for their low consumption of battery, and this feature stays on the . The new is EVOPS Line I-POWER SUPPLY 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 400.4 EVOPS amplifier is a versatile product that cover the entire audible frequency range, any type of loudspeaker or music program.]

M A R I N I Z AT I O N W I T H PROTECTION INDEX IP64

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.

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/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 th (+) e 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 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.

Warning

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

ELECTRICAL DIMENSIONING AND AUDIO INPUTS

ELECTRICAL DIMENSIONING

For proper operation of your Nondigital 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

****All RCA inputs must be connected for the amplifier to work properly. If the signal source is mono type, use “Y” cable at the input.

CROSSOVER SET UP

“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 “F” position (Full Range) – All the frequencies will be reproduced.
  

• Change the switch to “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 “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 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).

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:

All cables, positive and negative, connected from the battery to the busbar must be the same length. Likewise the cables connected from the busbar to the amplifier.

Battery connections without the use of a busbar, as shown in the example below, must be avoided. This setting decreases the efficiency of supplying power to the system
