The cables of the speakers should be polarized (marked) to facilitate the identification of positive and
negative. The circumference should be at least 8mm². Keep the cables from the speakers properly
insulated. Beware of metal parts that can damage the insulation of cables.
ATTENTION:
USE OF EXTERNAL FUSE OR BREAKER
BECAUSE THE AMPLIFIER HAS NO INTERNAL FUSE.
INSTALLATION OF OUTPUT SPEAKER
For the installation of power, choose cables with 21mm 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.
INSTALLATION OF POWER (BATTERY)
OVERVIEW
AUDIO INPUT, CONTROLS AND OUTPUT AUDIO AMPLIFIED.
INPUT VENTILATION AND POWER.
1) 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.
2) 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.
3) SUB SONIC 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.
4) 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.
5) COOLER:
Cools the internal components of the amplifier. The air enter in the cooler and exits through
the exhaust ventilation.
6) 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
(2 OHMS 3K7 E / 2OHMS ).
Use cables of at
least 8 mm2.
9) + BATT:
Connect the terminal (+ BATT) to the positive pole of the battery (+12 V) with a cable of at
least
(25mm² 3K7 E / 2 OHMS)
. 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.
10) 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.
11) GND - GROUND CONNECTION:
Use cable with
(25mm² 3K7 E / 2 OHMS)
. 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.
INSTALLING THE INPUT CABLES.
For the input entrance, use quality RCA cables with shield to avoid interference from
the car.
