PROBLEM DIAGNOSYS SYSTEM
In case that a problem occurs, the amplifier will turn OFF and the RED led will blink alternating
with the BLUE led. Depending on the problem, the BLUE led will flash a number of times. This way will
have a diagnosys folowing the table showed below:

Obs: in case the RED led blinks (blue is off), reconnect the device, if the problem
continues, look for a STETSOM authorized assistance.
HOW TO PROCED IN CASE OF MALFUNCTION
DOESN'T TURN ON:
The cables are not well connected (Terminals +BATT, GND and REM). Be sure that all connections have
electrical and mechanical connection. The fuses are burned or with defect. Pay attention on the values
of the new fuses.
NO SOUND:
The speaker cables or RCA plugs are not correctly installed.
Verify if level control is minimal.
NO SOUND / RED LED OF PROTECTION IS BLINKING:
See Page 04.
Speakers or cables with defect, check all speakers and wire connections.
BAD SOUND QUALITY (Distortion):
The speakers are overloaded, diminish the level and remake the gain adjust (see item 2).
WEAK LOW'S:
(-) and (+) speaker cables are misplaced, speaker out of fase (see item 4).
MOTOR NOISE, HORN, SIGNAL, ETC...
Use suppressive ignition coils on the spark plugs.
Use a condenser on the alternator, horn and ignition.
Use the input cable away from any other cables because it’s the most sensible to interference.
Make the 12V connection separately from the sound one, use a fuse 30cm away from the battery post.
Make a good ground connection on the amplifier. For this remove any paint of the point in the chassis of
the car. screwing directly to the chassis then use paint to protect from rust.
Don't make a loop with GND. Avoid using several GND. Use a star connection for all the GND from a
single point.

For the installation of the power cables, use cables
with a gauge of 70,0 mm² (14K2 ES e 11K2 ES) and
50,0 mm² (7K2 ES). the positive cable must come
directly from the battery, with a fuse or fuse breaker
installed at 30cm from the battery. The negative cable
must have the same gauge as the positive one and
must be fixed in the chassis of the car, being careful
with paint and rust that may prevent the passage of
electric current thus causing loss of power and noise
on the sound system.

1.OUTPUT - RCA Output: This output can be used optionally to play with another amplifier,
facilitating the installations with multiple amplifiers.
2.INPUT – RCA CONNECTION: This input should receive the signal trough a RCA cable that must
be connected to the RCA output of the CD/MP3 player.
3.LEVEL – GAIN CONTROL: Controls the input signal that comes from the CD/MP3 player allowing
a correct adjustment. For a correct use play a musical signal, put your CD/MP3 volume at 80% and
the gain control at 0%, then start to increase the gain until you notice distortion, to finish return the
gain a little bit.
4.SUB SONIC FILTER: Enables a cut on the low frequency sounds (subsonic`s). This filter is very
useful when using woofer type speakers. In this cases the woofers can’t handle subsonic sounds,
and may even damage the woofers depending on the type of sound used. The setting goes from
10Hz to 80Hz.
5.LOW PASS FREQ. – FREQUENCY CUT CONTROL: This control allows you to choose the
frequency cut of the channels filter (crossover) between 50Hz and 15KHz. This filter only allows the
signals that are below of the frequency cut.
6.SPEAKER OUTPUT: This output is MONO. Observe that there are four posts for connection,
however its not necessary to use all posts. You Just need a positive and a negative. Be careful with
the correct polarity of the speakers. The minimal association permitted is 2 ohms. Use at least 8mm²
cables.
7.COOLER: It helps the internal temperature of the components to below.
8.REM – REMOTE TURN-ON: Connect the REM terminal to the electrical antenna output of you
CD/MP3 player. This way when you CD/MP3 player, the amplifier will automatically turn on. A 0.5mm
cable is sufficient.
9.+BATT – POSITIVE FEED: Connect the post (+BATT) to the positive post of the battery (+12V)
with a cable of at least 70,0 mm² (14K2 ES e 11K2 ES) and 50,0 mm² (9K2 ES e 7K2 ES). Its
extremely important that a fuse or circuit breaker is used at a distance of 30cm away from the
positive post of the battery.
10.GND – GROUND CONNECTION: Use a 70,0 mm² (14K2 ES e 11K2 ES) e 50,0 mm² (9K2 ES e
7K2 ES) cable. Connect the cable to the car chassis. OBS: always plug the wire GND (-) of the
CD/MP3 player or other devices in the same point.
The speaker cables should be marked with negative and positive to facilitate the installation process.
The cables must be at least 10mm², they must be well isolated.
Be careful with sharpen edges that may damage the cable. The minimal impedance is 2 ohms.
