1. Make sure that your vehicle has a 12V DC electrical system with negative grounding. Before installing this DSP unit in cars,
trucks or buses, check the battery voltage.
2. Check the state of on-board power supply of your vehicle, the battery and the alternator. When the engine is running,
depending on the ambient temperature, the voltage to be outputted by the alternator must be within the range of 14 to 14.7 V.
Open circuit voltage (OCV) of the battery must be within the range of 12.5 to 13 V.
3. Do not place the DSP unit in the engine compartment and also in the places exposed to water, moisture, dust or dirt.
4. Never stretch the cables outside of the car and near the moving parts of the car. This can lead to destruction of the
insulating layer, short circuit and fire.
5. The DSP unit should be installed in areas of the car where the temperature varies from 0 °C (32 °F) to 55 °C (131 °F). The DSP
unit should be in a place with a good air circulation. The horizontal position of the DSP unit is the best way to install.
6. During the operation the DSP unit may be heated up to 80 °C (176 °F). Before you touch it, make sure it is not overheated
that may be dangerous.
7. To improve the cooling of the DSP unit, it is recommended to clean periodically the heatsink from dust. When cleaning the
heatsink strong solvents should not be used as they may damage the DSP unit. Do not use compressed air, because solids can
penetrate inside the DSP unit. Cleanings best done with wet towels or cloth.
8. Make sure that the location of the DSP unit does not violate the proper operation of mechanical and electrical devices of
the vehicle.
9. Make sure that during the installation and connection of the battery, the power cables are not shorted.
10. When performing plumbing, drilling or cutting works with the car, make sure that there is no wiring, brake lines, fuel pipe
or other structural elements under the place of work. Follow the safety rules! Use protective glasses and gloves.
11. To protect the wires use rubber gaskets if the wire passes through a hole in the plate, or other similar materials if it lies
close to the parts exposed to heat.
12. Make sure that all the cables are fixed over the entire length. Also make sure that their outer protective shell is non-
combustible. Use a clamping screw to secure the positive and negative cables next to the appropriate terminals of the DSP unit.
13. To avoid accidental damage, keep the DSP unit in its original packaging prior to installation.
14. Use high-quality copper RCA, speaker and power cables.

1. Before installing the DSP unit disconnect the battery from the electrical system.
2. To connect the DSP unit it is necessary to stretch the power cable from the location of the battery to the place of installation
of the DSP unit. Select the power cable with the appropriate regulations in AWG.
3. Connect the power supply with the correct polarity. Connect (+) terminal of the DSP unit to the cables stretching from the
positive terminal of the battery and (-) terminals of the DSP unit – to the cables stretching from the negative terminal of the
battery.
4. Place the fuse holder for each positive cable within 40 cm from the positive terminal of the battery and connect one end of
the power cable to the holder after connecting the other end to the DSP unit. Do not install the fuse.
5. Route all signal cables next to each other and separately from the power cables.
6. Connect the wires of RCA input. The input signal power must be between 0.2 V - 6 V.
7. To connect the power wire supply is necessary to use special power cables.
8. Fasten the DSP unit properly when installing it in the vehicle. If the component is disconnected during driving, it may cause
serious damage to the passengers of the vehicle or another vehicle. It is not recommended to screw the DSP unit directly to the
metal it can lead to distorsions at the signal outputs.
9. After installation is complete, check the wiring of the system and make sure that all connections have been made correctly.
Before installing the fuse, disconnect the positive lead from the battery and then install the fuse in the fuse holder. Using the light
bulb 12 V 21 W, connect the positive lead to one contact of the bulb and the other contact of the bulb to the positive terminal of
the battery.
When properly connected, the bulb must briefly light up and go out. Now you may connect the positive lead to the (+) of the
battery. If the light does not go out, then something is wrong. This will prevent damage to the DSP unit in case of reverse polarity
and unwanted sparks when connecting.
10. To activate the DSP unit, it is necessary to apply the positive potential of 12 volts to the control input of the DSP (REM IN)
through a switch or a corresponding control output (REMOTE OUT) with the head unit (HU) or use the DSP power-on switch
labeled "TURN ON" to select the desired auto power-on mode.
11. LED indicator on front of the DSP unit turns green to indicate that the DSP unit is turned on.
