Note: If only the RED LED blinks (BLUE LED OFF), turn on the device with the volume of CD/MP3-player down. If
the problem persists, please contact us.
LEDS INDICATORS (TOP OF THE AMPLIFIER)
SYSTEM TROUBLESHOOTING
- RED LED (PROT) illuminates only when
there is a problem in the functioning of
the device.
- RED LED (CLIP) flashes when
the amplifier output begin to
distort the sound.
- BLUE LED (POWER)
lights when the power
is on.
If a problem occurs, the amplifier will turn off and the LED RED / PROT flashes. As the problem occurred, the RED
LED / PROT will flash a number of times. So we have a diagnosis according to the table below:
NOT TURN ON:
- The cables are not properly connected (terminals +BATT, GND and REM). Make sure that all
connections are mechanical and electrical contact.
- Fuses / breakers (external) are defective or burned. Pay attention to the correct value of the new fuse!
NO SOUND:
- The cables of the speakers or RCA plugs are not connected correctly.
- Check that the LEVEL control is not in the minimum.
NO SOUND/PROTECTION RED LED FLASHING:
- See diagnosis UP (SYSTEM TROUBLESHOOTING).
- The speakers or cables defectives thus check the speakers, cables and connections.
POOR SOUND QUALITY (DISTORTION):
- The speakers are overloaded, therefore decrease the level and redo the gain setting (See item 4 /
OVERVIEW).
WEAK BASS:
- Cables speakers (+) and (-) are reversed, speaker out of phase (see Section 8 / overview).
MOTOR NOISE, HORN, SIGNAL LIGHT, ETC:
- Use suppressive cables in ignition candles.
- Use capacitors in the alternator, horn and ignition.
- Pass the RCA cable away from any other cable, because it is more sensitive to interference.
- Connect to power (+12 V) to separate the sound system. Use a fuse to 30 cm from the battery for
protection.
- Make a good grounding of the amplifier. To do this removes the paint from the chassis of the vehicle at
the desired point. Screw the cable using a ground terminal. To protect from oxidation, insulate with
paint.
- Do not loop the ground wire. Avoid using several ground wires. Prefer a star connection, with all the
ground wires aside from a single point.

INSTALAÇÃO DA ALIMENTAÇÃO (BATERIA)
ATTENTION: USE OF EXTERNAL FUSE OR BREAKER BECAUSE THE
AMPLIFIER HAS NO INTERNAL FUSE.
*FUSE: 400A
MÁX
30 cm
For the installation of power, choose cables with 70mm ². The
positive cable should come straight from the battery with a fuse or
circuit breaker protection located 30cm from the battery. The negative
cable should have the same circumference of the positive, and
screwed into the chassis of the vehicle, taking care to avoid paint and
rust that may prevent the passage of electric current, causing power
loss and noise in the sound.
INSTALLING THE INPUT CABLES.
For the input entrance, use quality RCA cables with shield to avoid interference from the car.
(We recommend the Triple Shielded RCA Cables - STETSOM)
OVERVIEW
AUDIO INPUT, CONTROLS
AND OUTPUT AUDIO AMPLIFIED.
INPUT VENTILATION AND POWER.
1/12) VENTILATION: Allows heated air outlet of the amplifier.
2) OUTPUT - RCA OUTPUT: This output can be used optionally to play another amplifier, facilitating installation in multi-amplified
systems.
3) INPUT - INPUT RCA L and R: This entry should receive the signal by RCA cable that must be connected to the output RCA of
CD/MP3-Player.
4) LEVEL - GAIN CONTROL: Controls the level of the input signal, allowing a proper adjustment to any CD/MP3-Player of the
market. For practical purposes may be adjusted as follows:
a) CD/MP3-Player, put a musical signal and adjust the volume in 80% of maximum. For example, if the maximum volume of
CD/MP3-player is 45 (100%), adjusting for 36 (80%).
b) In the amplifier, from the LEVEL at least, increase gradually until the clipping LED flashes.
c) Return the LEVEL slowly until the LED delete completely.
5) HIGH PASS FILTER: Provides a cut in the low frequency sound (subsonic). This filter is very useful when using speakers model
woofers. In these cases, the woofers are not able to reproduce the subsonic and may even damage depending on the power and
music used. Its adjustment varies from 10Hz to 700Hz.
6) LOW PASS FILTER: This control varies frequency cut filter 50 Hz to 15KHz. This filter allows passing only the sounds below the
cut off frequency.
7) BASS: This control provides gain / attenuation ± 10dB at frequencies sound serious. Center frequency of 45Hz.
8) MID-BASS: This control provides gain / attenuation ± 10dB at frequencies of mid bass sound. Center frequency of 270Hz.
9) HIGH-MID: This control provides gain / attenuation ± 10dB at frequencies of sound medium-high. Center frequency of 2kHz.
10) OVER CLIP - ON / OFF: With this switch on, the LED will light Cliping with 15% more power end.
11) SPEAKERS OUTPUT: This output is MONO. Beware of the polarity of the connections with the speakers and check the
minimum impedance allowed in this output. Use cables of at least 10 mm2.
13/14/18) COOLER: Cools the internal components of the amplifier. The air enter in the cooler and exits through the exhaust
ventilation.
15) + BAT: Connect the terminal (+ BAT) to the positive pole of the battery (+12 V) with a cable of at least 70mm². It is extremely
important that you use a fuse or circuit breaker to protect this cable to a maximum distance of 30 cm from the battery.
16) REM - DRIVE REMOTE: Connect the REM terminal to output for remote / antenna electric of CD/MP3-Player. So when you turn
on your CD/MP3-Player, the amplifier automatically turns on. A cable of 0.5 mm² is sufficient.
17) GND - GROUND CONNECTION: Use cable with 70mm². Plug the cable into the chassis of the vehicle.
NOTE: Always connect the cable GND (-) of CD-Player, or other devices at the same point.
19) POWER LED (BLUE): The LED indicator lights up when the unit is triggered by the signal coming from the remote CD/MP3-
player.
20) PROT LED (RED): The LED will illuminate in the following situations:
a) Short-circuit the outputs speakers c) Low battery voltage
b) temperature above the allowed. d) High voltage battery
21) CLIP LED (RED): The LED lights up when the output signal start to distort.
The cables of the speakers should be polarized (marked) to facilitate the identification of positive and
negative. The circumference should be at least 10mm². Keep the cables from the speakers properly
insulated. Beware of metal parts that can damage the insulation of cables.
