General Description
Features
The
EX1200EQ
offer 1 channel with advanced individual equalization features for Bass, Mid Bass and Mid High, plus the
traditional
Level
,
High Pass
and
Low Pass
features. Its Full Range frequency response from 10Hz to 25KHz allows the
installation of Subwoofers, Woofers, Drivers and Twitters.
Before Installing
Read this manual carefully before installing the amplifier. You must follow the instructions for the product’s installation
and connections to guarantee optimal performance. If you have any questions, get in touch with us. Before using the
amplifier, always follow these guidelines:
• Make sure the appliance is switched off before adding or removing any connections. This prevents possible damage to
the equipment connected to the amplifier;
• Keep all cables as far away as possible from the ignition cables, electronic injection modules and starter switch since
they may cause noise interference;
• Always use good quality cables and connectors. This guarantees the sound’s quality and fidelity;
• To avoid damaging the cables, make sure that they do not touch sharp metal edges.
Important:
Use a 40A fuse 30 centimeters from the battery as a safety precaution.

VENTS:
Allows for the removal of warm air from the amplifier.
INPUT RCA:
This input should receive the signal through an RCA cable connected to the output of the CD/MP3 player.
LEVEL (LEVEL CONTROL):
Controls the input signal level, allowing for proper control of any CD/MP3 player currently
on the market. It can be regulated as the following:
a)
on the CD/MP3 player, play any musical signal up to 80% volume.
(Ex: If the maximum volume on the player is 45 [100%], adjust to 36 [80%]).
b)
on the amplifier, beginning at the lowest LEVEL, gradually increase until the clipping LED begins to flash.
c)
slowly decrease the LEVEL until the LED goes off.

General Description
HIGH PASS FILTER:
Allows cut off of low frequency (subsonic) signals. This filter is very useful for woofer-type speakers.
In these cases, the woofers are not capable of reproducing subsonic frequencies, and these subsonic frequencies may
even cause damage depending on the volume and the music played. It is regulated from 10Hz to 700Hz).
LOW PASS FILTER:
This control varies the cut off frequency from 50Hz to 25KHz.This filter allows to pass only sounds
beneath the cut frequency.
BASS:
This control provides gain/attenuation of ±10dB in low frequency. Central frequency is 45Hz.
MID-BASS:
This control provides gain/attenuation of ± 10dB in mid-low frequency. Central frequency is 270Hz.
MID-HIGH:
This control provides gain/attenuation of ±10dB in mid-high frequency. Central frequency is 2KHz.
OVER CLIP (ON/OFF):
With this key turned on, the clipping LED will light up at 15% more final capacity.
SPEAKER OUTPUT:
This output is
MONO
. Be careful of maintaining the correct polarity of the connections between
the speakers and check the minimum impedance of this output. Use cables with a minimum gauge of
11 AWG
.
COOLER:
This fan will operate according to the volume of the CD/DVD/MP3 player. The higher the volume, the higher
speed at which the fan will run.
FAN CONTROLLED BY AUDIO.
POSITIVE POWER SUPPLY
: Connect the terminal
(+BAT)
to the positive terminal of the battery (+12V) with a
minimum gauge of
6 AWG
. It is extremely important that a protective fuse or circuit breaker be used on this cable
at a distance of 30 cm from the battery. The fuse or circuit breaker should be, at minimum, equal to the max current
consumption value caused by playing musical signals (see technical specifications table).
REM (REMOTE CONTROL):
Connect the REM terminal to the electric antenna output of the CD/MP3 player. This will
cause the amplifier to turn on automatically when you turn on your CD/MP3 player. A cable with a gauge of
20 AWG
is adequate.
GROUND CONNECTION :
Use a cable with a gauge of at least
6 AWG
. Connect the cable to the chassis of the vehicle.
(Note: always connect the GND wire of the CD player—or other equipment—to the same ground point.)
POWER LED (BLUE):
This indicator LED will light up when it is activated by the remote control signal from the CD/MP3
player.
PROT LED (RED):
This LED will light up for the following reasons (see the diagnostic table on the back cover):
a)
Short circuit in the speakers
c)
Low battery voltage
b)
Excessive temperature
d)
High battery voltage
CLIP LED (RED):
This LED will light up when the signal begins to suffer distortion.
Installing the Input Cables
In order to install the power supply, use cables with a gauge of
6 AWG
. The
positive cable should come straight from the battery and have a fuse or protective
breaker 30cm from the battery. The negative cable should have the same gauge
as the positive cable and be screwed to the chassis of the vehicle, being careful to
avoid paint and rust. These may interfere with the flow of the electrical current
and cause loss of power and interference in the sound.
RECOMMENDED USE OF
AUXILIARY BATTERY.
ATTENTION:
The use of a the fuse or
breaker is required, since this amplifier
has no internal fuses.
