CAUTION

Before you start with the installation, disconnect necessarily the GROUND connection wire from the battery to avoid any risk of electric shocks and short circuits.

ELECTRICAL INTERCONNECTION

BEFORE CONNECTING

For the professional installation of a sound system, car audio retail stores offer appropriate wiring kits. Ensure a sufficient profile section (refer to the table on the next page) and a suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and remove rust-streaked and oxidized areas on the contact points of the battery and the ground connection. Make sure that all screws are fixed tight after the installation because loose connections cause malfunctions, insufficient power supply, or interferences.

1. GND
   Connect the GND terminal with a suitable contact ground point on the vehicle’s chassis. The ground wire must be as short as possible and must be connected to a blank metallic point at the vehicle’s chassis. Ensure that this ground point has a stable and safe electrical connection to the negative “–” pole of the battery. Check this ground wire from the battery to the ground point if possible and enforce it if required. Use a ground wire with a sufficient cross-section (refer to the table on the next page) and the same size as the +12V power supply wire.

2. REM IN/OUT
   Connect a turn-on signal or the turn-on remote signal of your head unit (REM) with the REM IN/OUT terminal of the amplifier. Use therefore a suitable cable with a sufficient cross-section (0,5 mm2). Hereby the amplifier turns on or off with your head unit. If you use the AUTO TURN-ON function (refer to page 24, section 9), the REM IN/OUT terminal does not need to be connected. However, the REM IN/OUT terminal can then be connected to the REM terminal of another amplifier to provide a control signal to it (REM OUT function).

3. +12V
   Connect the +12V terminal with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufficient cross-section (refer to the table on the next page).

4. FUSE
   The amplifier inherently has no internal device fuse. Use the supplied fuse (50 A) with the fuse holder and install it in the power cable between the 12 Volt pole of the vehicle battery and next to the +12V terminal of the amplifier. The distance between the fuse and the amplifier should not exceed 30 cm.

5. ADDITIONAL CABLE FUSE (NOT INCLUDED)
   Install an extra fuse (not included) for the +12V power cable near the battery to secure the power cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be adapted to the cable cross- section of the installed power cable (refer to the table below). IMPORTANT: The fuse on the battery does not protect the amplifier, but the cable between the battery and the amplifier against short circuits.

Recommended minimum cable cross-section to guarantee full amplifier performance: Up to a length of 3 m: 16 mm2
From a length of 3 m: 20 mm2

CAUTION

Replace defective fuses only with a new one of the same type and with the same fuse rating.

DESCRIPTION OF OPERATION

1. LINE INPUT
   Connect the LINE INPUT RCA jacks with the head unit by using appropriate audio signal cables. HIGH-LEVEL INPUT If your head unit does not have RCA preamp outputs, you can use the HIGH-LEVEL INPUT. Connect the loudspeaker cables of the head unit to the included cable harness.

2. LINE OUTPUT
   The LINE OUTPUT RCA jacks provide a linear full-range audio signal for driving additional amplifiers,
   such as the ZXR1200/1 monoblock.

3. AUTO TURN-ON
   If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of the amplifier. This works in two ways, which can be set at the AUTO TURN-ON switch:

4. DC: This method only works if you use the amplifier’s HIGH-LEVEL INPUT. The amplifier then detects a voltage rise to 6 volts when the head unit is turned on by a so-called “DC offset” and then turns on the amplifier. VOX: Select this method when using the LINE INPUT RCA jacks. The amplifier then detects a voltage increase in the incoming audio signal when switching on the head unit via the attached RCA cable and then switches on the amplifier.

5. Note: As soon as the head unit is switched off again, the amplifier switches itself off. The terminal for the amplifier turn-on can now be used to supply additional amplifiers with a turn-on signal. Simply connect the REM terminals of the two amplifiers and make sure that the other amplifier is in “normal” turn-on mode, which means that the AUTO TURN ON function is disabled.

6. BLC REMOTE
   The BLC REMOTE port is for connecting the cable of the included bass level remote controller. With this, the bass level can be e.g. be adjusted from the driver’s seat. Only use the supplied bass remote controller and the associated cable. The bass level remote controller only works in LP/BP mode (Low- Pass/Bandpass).
   POWER/PROTECT
   If the LED lights up in green, the amplifier is ready for operation. If the LED lights up in red, there is a malfunction. Refer in this case to chapter TROUBLESHOOTING on page 28.

7. LEVEL
   This controller determines the input sensitivity (adaptation to the output signal of the head unit).

8. X-OVER MODE
   This switch selects the desired operating mode of the amplifier:

9. FULL: Full Range mode – the entire frequency range is amplified

10. HP: High Pass mode adjustable with HIGH PASS – frequency is limited downwards,

11. LP/BP: Low Pass mode adjustable with LOW PASS – frequency is limited upwards,

The HIGH PASS controller acts as a Bandpass filter and limits the frequency downwards.
Note: If the HIGH PASS controller is set higher than the LOW PASS controller, no sound is heard.

1. HIGH PASS
   This controller limits the frequency downwards. Low frequencies that can damage a loudspeaker are cut off. The crossover frequency is adjustable from 10 Hz to 500 Hz.

2. LOW PASS
   This controller limits the frequency upwards. The crossover frequency is adjustable from 50 Hz to 5000 Hz (5 kHz).

3. BASS BOOST

This controller adjusts the bass boost from 0 dB to +12 dB at 45 Hz.

TROUBLESHOOTING

CAUTION

All instructions in this troubleshooting refer to the entire sound system and its individual components. The features of your device may not match the functions described in the notes. Then skip this point and move on to the next one.

NO FUNCTION / THE POWER LED IS NOT ILLUMINATED

First, check the fuse of the routed power cable on the vehicle battery
The fuse is defective

Replace the defective fuse with an equivalent one, never with a higher value.

•    The fuse fails again.

In this case, there appears to be a short circuit between the fuse and the amplifier. To do this, check the + 12V power cable along its entire length from the battery to the amplifier for damage and whether there is a short circuit to the ground, e.g. contact with the vehicle chassis or the body. If necessary, replace the defective power cable.

The fuse is apparently okay

Use a standard 12-volt voltmeter to check the voltage between the + 12V connection and the ground connection on the amplifier.

•    There is no voltage.

Use the voltmeter to check the fuse, which is located close to the vehicle battery, to see whether there is a voltage between the output and the ground.

If there is no voltage there, either the fuse holder or the fuse is defective, although it appears to be okay. If necessary, replace the fuse holder or fuse.

•    There is voltage.

If you operate the amplifier with a pre-amplifier signal (RCA), you must have laid a remote turn-on wire from the head unit to the REM terminal of the amplifier. The AUTO TURN-ON switch must be in the OFF position. However, you can test the AUTO TURN-ON switch to ON to see if the amplifier then turns on. If so, there is a problem with the control line.

•     A remote turn-on wire is connected to the REM terminal at the amplifier.

Use the voltmeter to check whether there is a voltage between the REM terminal of the amplifier and the ground. The head unit must be switched on.

There is no voltage.

•    Check the remote turn-on wire from the amplifier to the head unit for a short circuit or damage. If necessary, replace the control line.

There is voltage.

•    The amplifier is probably malfunctioning or defective. Contact your retailer.

If you operate the amplifier with the loudspeaker signals (high-level mode), the AUTO TURN-ON switch must be switched to ON.

•     The AUTO TURN-ON switch is in the ON position, but the amplifier remains off.

Check the speaker cables from the head unit to the amplifier for short circuits or damage. If necessary, replace the speaker cables or insulate the damaged area.

THE POWER LED IS ON, BUT NO SOUND COMES FROM THE SPEAKERS

Check the following steps:
Low-level mode: Are the RCA cables on the head unit and on the amplifier correctly connected?

•    The RCA cables are correctly connected.

Then an RCA cable could be defective. Check the function of the RCA cables on another audio device. If necessary, replace the defective RCA cables.

High-level mode Are the loudspeaker cables on the head unit and the high- level inputs of the amplifier or on the high-level cable plug correctly connected?

•    The speaker cables are connected correctly.

A speaker cable could be defective. If necessary, replace the speaker cable or insulate the damaged area.

Are the speaker cables correctly connected between the speakers or the subwoofer at the speaker outputs of the amplifier?

•    The speaker cables are connected correctly.

A speaker cable could be defective. If necessary, replace the speaker cable or insulate the damaged area.

Is the high pass filter or subsonic filter set higher than the low pass filter on the amplifier?

Then slowly turn down the controller for the high pass filter or subsonic filter until the sound can be heard.

Is the input mode switch on the amplifier set correctly?

Check the setting and change the switch position if necessary.

Are the crossover switches on the amplifier set correctly?

Check the settings and change the respective switch position if necessary.

Are the speakers or the subwoofer working?

Hold a standard 9-volt block battery to the terminals of each loudspeaker or the subwoofer.

•    A faint cracking sound can be heard. The speaker or subwoofer is fine.

•    There is nothing to be heard.

The loudspeaker or subwoofer could be defective. If necessary, replace the defective speaker or subwoofer.

Are the settings on the head unit set correctly?

•    Check the fader and balance settings

•    Check whether the mute function is activated

•    Check whether a high pass or low pass filter is activated

•    Check whether playback has been paused

•    Check the source settings

•    Check whether any existing subwoofer output is activated

TROUBLESHOOTING

DISTORTION OR HISSING NOISE CAN BE HEARD FROM THE SPEAKERS

Check the following steps:
Is an input level controller on the amplifier set too high?

Slowly turn the controller back until you hear a clean audio signal.

Is the Bass Boost controller on the amplifier set too high?

Slowly turn the controller back until you hear a clean audio signal.

Is the loudness function on the head unit set too high?

Deactivate loudness or turn the loudness setting back until you can hear a clean audio signal.

Are the EQ and sound settings on the head unit set too high?

Turn down the settings for Treble, Middle, and Bass, or deactivate the equalizer until you can hear a clean audio signal.

ENGINE SPEED-DEPENDENT NOISE CAN BE HEARD FROM THE SPEAKERS

Check the following steps:
Have the RCA cables been laid separately from the power cable in the vehicle?

If necessary, lay the cables again and make sure that the audio cables are laid separately from the power cable on the left and right of the vehicle.

Is the amplifier’s ground connection correctly connected?

Make sure that the ground connection of the amplifier is not connected directly to the negative pole of the vehicle battery. Select a suitable ground point on the vehicle body for connection. If necessary, use contact spray to improve the conductivity of the connections.

Is the conductivity of the ground cable from the vehicle battery to the body okay?

Make sure that the ground connection of the vehicle battery has a stable and conductive connection to the body. If necessary, use contact spray to improve the conductivity of the connections.

AN ACTIVE OPERATED TWEETER IS DISTORTED OR CRACKED

CAUTION: Tweeters will be damaged if the frequencies are too low. Please note the manufacturer’s information on which frequency setting is recommended. To be on the safe side, pause the play-back of the head unit first. Check the following steps:
Is the crossover mode switch of the relevant channel pair on the amplifier set correctly?

Set the crossover mode switch to the high pass position (HP or HPF).

Is the high pass filter of the relevant channel pair set too low on the amplifier?

First, turn the high pass controller fully clockwise. Now start playback on the head unit. Then turn the high pass controller slowly counter-clockwise until you can hear a clean sound from the tweeters and produce a balanced sound together with the woofers/mid-range speakers. Make sure that the woofers/ mid-range speakers are set correctly with the respective high pass and low pass controllers.

AMPLIFIER ACTIVATES THE PROTECTIVE CIRCUIT / THE PROTECT LED LIGHTS UP

Check the following steps:
Short circuit on the speaker cables

•     First disconnect all speaker cables from the amplifier. Use a multimeter to check the ohmic impedance of each loudspeaker by measuring between its plus and minus lines. With standard loudspeakers, the value fluctuates between 3 and 5 ohms. The values for low-resistance subwoofers can be lower.

•    The measurement shows a resistance value of fewer than 0.5 Ohms

Then there is a short circuit. Remove the wiring of the affected loudspeaker at its connections. Now use the multimeter to check the ohmic impedance directly at the loudspeaker connections by measuring between the plus and minus connections.

The measurement shows a resistance value of more than 0.5 Ohms

•    The speaker is fine, so the speaker wire appears to be defective and causes a short circuit. Replace the defective speaker cable.

The measurement shows a resistance value of fewer than 0.5 Ohms

•    The speaker appears to be defective and is shorting out. Replace the defective speaker.

The load impedance of the loudspeakers or the subwoofer is too low

•     Compare the ohmic impedance of the connected loudspeaker or subwoofer with the technical specifications of the amplifier. For example, if the amplifier is only designed for 2 or 4-ohm operation, no loudspeaker with less than 2 ohms may be connected.

The cross-section of the power cables is too small

•     If the cable cross-section is too small, this leads to increased ohmic resistance and thus to a voltage drop (voltage loss). This indicates that the amplifier consumes more power. The increased power consumption results in a significantly higher heat development and the amplifier switches to thermal protection mode. Therefore, observe the recommended cable cross-sections in these instructions and, if necessary, lay power cables with a larger cable cross-section.

The amplifier is overheated

•     The heat sink of each amplifier requires sufficient air circulation to be able to dissipate the heat generated during operation. If necessary, change the installation position in favor of better cooling of the amplifier or ensure better air circulation at the installation location.

•     Turn off the sound system and wait about half an hour for the amplifier to cool down again. With very hot outside temperatures and strong sunlight, enormous heat develops inside the vehicle. The amplifier then activates its thermal protection circuit to prevent damage. After cooling down, the amplifier works properly again.

CAUTION

All instructions in this troubleshooting refer to the entire sound system and its individual components. The features of your device may not match the functions described in the notes. Then skip this point and move on to the next one.
