Wenn irgendetwas nicht funktioniert / Trouble shooting /
En cas… de non fonctionnement
Dieser Verstärker hat Schutzfunktionen die Schäden durch unsachgemäße Bedienung oder Bedingungen verursacht werden. Wenn das Gerät
extreme Hitzeentwicklung, einen Kurzschluss oder eine Überladung feststellt, leuchten die Protection LEDs und das System schaltet sich ab.
Um das auftretende Problem zu prüfen sollten Sie alle Regler zurückdrehen, die Stromversorgung abklemmen und die Installation sorgfältig auf
Kurzschlüsse oder falsche Anschlüsse prüfen.
Wenn sich das Gerät aufgrund hoher Hitze abschaltet leuchten die Protection LEDs nicht. In diesem Fall lassen Sie dem Gerät einfach Zeit um
abzukühlen.
Beachten Sie die folgende Tabelle, bevor Sie das Gerät ausbauen. Testen Sie immer die Lautsprecher und Verkabelung an erster Stelle.

This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit senses excessive heat, short
circuited speakers or overload, the protection indicators will light, and the system will be turned off. In order to check the occurred problem, you
should turn all levels down and all power off and carefully check the installation for wiring mistakes or short. If the amplifier shuts down due to
excessive heat, the protection indicators will not light: simply allow time for the unit to cool. Before removing your amplifier, refer to the list below
and follow the suggested procedures.
Always test the speakers and their wires first.
Problem Check points
Amplifier is
not powered up
•Check that there is battery power on the +12V terminal.
•Check that remote terminal has at least +12V DC remote connection.
•Check a good ground connection. Check all fuses.
•Check the protection LED is not lit.
Protection LED illuminates
when amplifier is powered
up
•Check shorts on speaker wires.
•Remove speaker wires and reset the amplifier. If the protection LED still comes on, then the
amplifier is faulty.
Fuse blowing
•Check that the minimum speaker impedance is correct.
•Check short on power cable and vehicle chassis.
Overheating
•Check that the minimum speaker impedance is correct.
•Check speaker shorts.
•Check that there is a good airflow around the amplifier.
Sound too low / Distorted
sound
•Check that the input level control is set to match the output level of the unit.
•Check the head unit volume.
•Check speaker shorts.
•Check that crossover frequencies have been properly set.
Hi
g
h hiss /
engine noise
in speakers
•Check a good ground and for speaker shorts.
•Disconnect all RCA inputs from the amplifier. If hiss/noise disappears, check it with a good RCA
interconnect. Then check the component driving the amplifier.
Cette amplificateur et équiper de protection pour éviter tous dégâts en cas de mauvaise manipulation .Si l’ampli détecte une anomalie (court-
circuits – surchauffe ) l’ampli se coupe automatiquement . Pour examiner le problèmes vérifier tous vos branchements , le temps que l’ampli
refroidisse . vérifier en premier les Haut parleurs puis tous les câbles d’alimentation . si le problèmes persiste consulter un technicien.
