WARRANTY

This product meets the current EU minimum warranty requirements, if purchased in countries of the EU. To ensure your warranty policy keeps your original receipt proofing the date of purchase. Any damage to the product as a result of misuse, abuse, accident, incorrect wiring, improper installation, alteration of date code or barcode labels, revolution, natural disaster, or any sneaky stuff because someone messed up, repair or alteration out side of our factory or authorized service centers and any thing else you have done that you should not have done is not covered. This warranty is limited to defective parts and specifically excludes any incidental or consequential damages connected therewith.

IMPORTANT NOTES PRIOR TO INSTALLATION

• This device is only suited for a 12 volt system with negative ground.
• The radiated heat while operation requires sufficient air circulation at the place of installation. It is very important that the heatsink fins do not have contact with any metal parts or any surfaces which could impair air circulation. The amplifier may not be installed in small closed location or spaces without air circulation (e.g. spare wheel recess or below the vehicle carpeting). We recommend the installation in the vehicle's trunk. Ensure sufficient protection against vibrations, dust and dirt.
• Ensure that the input and output cables are sufficiently separated from the power supply cables. Otherwise interferences may occur.
• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the amplifier depends on the quality of installation. Preferably consult an expert to install the system, particularly if you want to install several loudspeakers.

INTERCONNECTION

POWER SUPPLY AND TURN-ON-CONNECTION

ATTENTION: Before you start with the installation, disconnect the ground connection from the vehicle's battery in order to prevent short circuits.

The power wiring which is usually installed in on-board car networks is not sufficient for a power amplifier's demands. Make sure that the power wires to GND and to the +12V terminal has been sufficiently specified. A cable crosssection of at least 10mm^2 must be used to connect the battery to the amplifier's terminals.

First connect the GND terminal of the amplifier to an appropriate ground connection at the chassis. To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion.

Then connect the +12V terminal of the amplifier with the battery by using an appropriate cable including an in-line fuse. This fuse should be located very close to the battery; for safety reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been accomplished.

Then connect the remote turn-on-wire from the headunit with the amplifier's REM terminal. A cable with a cross-section of 0.5mm^2 is adequate.

LOUDSPEAKER CONNECTIONS

• In 4-channel operation (i.e. one loudspeaker on each amplifier channel), the impedance must not be lower than 2 ohms for each speaker
• In bridging mode (two amplifier outputs combined) the impedance must not be lower than 4 ohms for the bridged output.
• Never connect loudspeaker cables with the ground of the chassis or the +12V supply voltage.

If the amplifier is operated with a too low impedance or incorrectly used, the entire sound system may be damaged. This means a warranty void in such cases.

AUDIO SIGNAL CABLES

When installing the audio cables between the RCA outputs of the headunit and the RCA inputs of the amplifier, the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on the left side and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents interferences due to crosstalk into the audio signal.

SIGNAL OUTPUTS TO CONNECT ADDITIONAL AMPLIFIERS

The input signal on the INPUT FRONT jacks (Fig. 1,6) will be routed in stereo to the output jacks OUTPUT (Fig. 1,7). Thus the OUTPUT jack allows the connection of a additional amplifier.

OPERATING ELEMENTS

INPUT SENSITIVITY FRONT & REAR

Turn the LEVEL (Fig. 1,5 REAR and fig. 1,9 FRONT) controller of the amplifier to the MIN position. Then turn the volume controller of the headunit to 80 - 90% of its full setting. Now turn LEVEL clockwise until you hear some distortion. Then turn back the LEVEL slightly until you hear a cleaner sound.

VARIABLE HIGHPASS FILTER FRONT & REAR

If the amplifier is to be used for mid-range/tweeter loudspeakers, set the switches X-OVER (Fig. 1,2 REAR and fig. 1,10 FRONT) to HP. Then set the desired cross-over frequency on the HIGH PASS controller (Fig.1,1 REAR or fig. 1,11 FRONT). Thus to that only the frequencies above the chosen cross-over frequency will be amplified. This effectively minimizes distortions and overloads at lower frequencies. A good point to start is at 125Hz .

If you use loudspeakers (>20cm) set X-OVER (Fig.1,1 REAR or fig. 1,11 FRONT). to FULL. In this case, the HIGH PASS controllers (Fig.1,1 REAR or fig. 1,11 FRONT) are without function.

VARIABLE LOWPASS FILTER REAR

If the amplifier is used to drive a subwoofer, set the switch (Fig. 1,2 REAR) to „LP“. Set the desired cross-over frequency by using the controller (Fig. 1,1 REAR). Thus to that only the frequencies below the chosen crossover frequency will be amplified and the subwoofer plays more precised and efficient.

SWITCHABLE BASS EQ REAR

By using the BASS EQ switch (Fig.1,4 REAR) you are able to increase the bass level by 6 or 12 dB at 45Hz . Attention: Use the BASS EQ wisely!

PROTECTION CIRCUIT

The Operation-LED (POWER, fig. 1,12) lits up, if the amplifier is in operation.

The protection LED (PROTECT, fig. 1,12) lits up, when the amplifier is overheated, or a short circuit occurs resp. a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts down the amplifier automatically. The amplifier should work again properly after you have solved the problems.

IMPORTANT!

Always observe the correct polarity of all connections!

TROUBLESHOOTING

If you are having problems after installation follow the Troubleshooting procedures below.

Procedure 1:

Check Amplifier for proper connections.

Verify that POWER LED is on. If POWER LED is on skip to Step 3, if not continue.

1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Check fuse(s) on amplifier. Replace if necessary.
3. Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if necessary.
4. Verify there is 9 to 16 Volts present at the positive battery and remote turn-on cable.Verify quality connections for both cables at amplifier, stereo, and battery/fuseholder. Repair/replace if necessary.

Procedure 2:

PROTECT LED is on.

1. If the PROTECT light is on, this is a sign of a possible short in the speaker connections. Check for proper speaker connections and use an ohm meter to check for possible shorts in the speaker wiring. Too low speaker impedance may also cause PROTECTION to light. This can also be a sign of driving the amplifier at very high power levels without adequate airflow around the amplifier. Shut off the system and allow amplifier to cool. Check that the vehicle charging system is maintaining proper voltage. If the previous items do not solve the problem, a fault may be in the amplifier. In this case you should contact your dealer.

Procedure 3:

Check Amplifier for audio output.

1. Verify good RCA input connections at stereo and amplifier. Check entire length of cables for kinks, splices, etc. Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.

Procedure 4:

Check Amplifier for a popping noise while turning on.

1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REMOTE lead of amplifier to source unit with a delay turn-on module.

OR

1. Use a different 12 Volt source for REMOTE lead of amplifier (i.e. battery direct).
2. If the noise is eliminated, use a relay to isolate the amplifier from noisy turn-on output.

Procedure 5:

Check Amplifier if you experience excess Engine Noise.

1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.

OR

1. Bypass any and all electrical components between the headunit and the amplifier(s). Connect stere directly to input of amplifier. If noise goes away the unit being bypassed is the cause of the noise.

OR

1. Remove existing ground wires for all electrical components. Reground wires to different locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.

OR

1. Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.

OR

1. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.
