TROUBLE SHOOTING
ELECTRICAL INTERFERENCES
The reason for interferences are mostly the routed cables and wires. Especially the power and audio cables (RCA) of your sound system
are vulnerable. Often these interferences are caused by electric generators or other electrical units (fuel pump, AC etc.) of the car. The
most of these problems can be prevented by a correct and careful wiring.
Here are some courtesy notes:
1. Use only double or triple shielded audio RCA cables for the connection between the amplier and headunit. An useful alternative
are represented by anti-noise-devices or additional ancillary equipment like Balanced Line Transimtters, which you can purchase
at your car audio retailer. If possible do not use anti-noise-lters, which are splicing the ground of the RCA audio cables.
2. Do not lead the audio cables between the head unit and the amplier together with the power supply wires on the same side of
the vehicle. The best is a real separated installation on the left and right cable channel of the vehicle. Then the overlapping
of interferences on the audio signal will be avoided. This stands also for the enclosed bass-remote wire, which should not be installed
together with the power supply wires.
3. Avoid ground loops by connecting all ground connections in a starlike arrangement. The suitable ground center point is
ascertainable by measuring the voltage directly on the vehicle’s battery by a multi-meter. You should measure the voltage with
turned-on inginition (acc.) and with other turned-on power consumers (e.g. headlights, rear window defroster, etc,). Compare
the measured value with the voltage of the ground point you have choosen for the installation and the positive pole (+12V) of
the amplier. If the voltage has just a little difference, you have found a suitable ground point. Otherwise you need to choose an
other ground point.
4. Use if possible only cables with added or soldered cable sockets or the like. Gold plated or high value nickel plated cable sockets
are corrosionfree and own a very low contact resistance.
PROTECTION CIRCUIT
This amplier owns a 3-way protection circuit. On overloading, overheating, shorted loudspeakers, too low impedance or insufcient pow-
er supply, the protection circuit turns off the amplier to prevent serious damage. If one of this disfunctions is detected, the red PROTECT
LED lights up.
In this case, check all connections to detect short-circuits, faulty connections or overheating. Refer to the notes on the next page.
If the reason for the disfunction is eliminated, the amplier is ready for operation again.
If the red PROTECT LED does not stop to light up, the amplier is damaged. In this case return the amplier to your car audio retailer
with a detailled malfunction description and a copy of the proof of purchase.
WARNING: Never open the amplier and try to repair it by yourself. This causes a loss of warranty. The repairing service should be made
only by skilled technicians.
INSTALLATION AND OPERATION IN NEWER VEHICLES!
In vehicles with a newer year of manufacturing (since approx. 2002), normally computer controlled diagnosis- and controlling systems are
applied - like CAN-BUS or MOST-BUS interfaces. With the installation of a car audio amplier a new appliance will be added to the 12V
on-board electrical system, which may cause under several circumstances error messages or may interrupt the factory made diagnosis
system, as a result of high stress peaks and a higher power consumption. Thus, depending on model and manufacturer, the driving safety
or important security systems like airbags, ESC or others could be interrupted.
If you plan to operate the amplier in a vehicle like described above, please follow these instructions:
• Let the installation be made only by a skilled specialist or a service station, which is specialized for the maintenance of your vehicle.
• After the installation, we suggest to make a computer diagnosis of the on-board system, to detect possible malfunctions or errors.
• If the on-board system is interfered by the installation of the amplier, an additionally installed power capacitor can stabilize the electrical
on-board system to ensure a proper and stable operation.
• The best solution is the integration of an own additional 12 V electrical system for the sound system, which can be operated
independently with an own battery supply.
CONSULT YOUR CAR SPECIALIZED SERVICE STATION!
