Problems solution
DOES NOT TURN ON OR LED'S DO NOT LIGHT UP:
Power cables are not connected correctly or poorly contacted (terminals +12V, GND,
and REM). Check connections and grounding.
Remote activation (REM) connection with no voltage. Verify that the connection is
receiving voltage near 12V.
NO AUDIO SIGNAL:
Controls on LEVEL channels at the minimum, increase the level.
The audio cables might be disconnected or with bad contact. Check the connections.
DISTORTED AUDIO SIGNAL:
Signal in audio distorted/saturated. Adjust the volume level of the source signal, as well
as the controls of gain channels.
UNDESIRABLE NOISES:
All cables (RCA and power) should be previously checked, to overcome any irregularity
found.
Use suppressive cables on the ignition candles.
Pass the RCA cable's Input and Output away from any other cable, since they are more
sensitive to interferences.
Make the power connection installation (+12V) separate from the sound system.
Make a good grounding of the product. For this, remove the ink from the chassis of the
vehicle on the wanted point and screw the wire, using a ground terminal. To protect it
from oxidation, insulate it with ink.
Leave the grounding point the nearest possible to the others equipment grounding used
on the set, avoiding loop. Prefer the star connection with every ground leaving it from a
single point.
