POWER SUPPLY AND TURN-ON CONNECTION

To connect the power supply, only use power cables that are sufciently dimensioned (See page 43, g. 5). The cross-section of the cables must be the same size for +12V and ground. First establish a connection between the GND terminal of the amplier and a suitable ground point on the ve- hicle body (Fig. 2.1). To guarantee a good connection, remove any dirt and rust from the ground point. Then connect the +12V terminal of the amplier to the positive terminal of the vehicle battery (Fig. 2.3). In addition, the positive power cable must be protected with another fuse near the battery (Fig. 2.5). This fuse is not included in the scope of delivery and should have the same fuse value as the included fuse. For safety reasons, the cable length from the positive terminal of the battery to the fuse must be less than 30 cm. Then connect the power cable of the car radio to the REM terminal (Fig. 2.3) of the amplier. A cable with a cross-section of approx. 0.5 mm

is sufcient for this connection. LOUDSPEAKER CONNECTION

• The total impedance must be not lower than 2 Ω per loudspeaker output

• The total impedance must be not lower than 4 Ω per two bridged loudspeaker outputs CAUTION: If the amplier is operated with speaker impedances that are too low, it could be overloaded and thus permanently damaged. STATUS LED The POWER/PROTECTION LED (Fig. 1.1) lights up blue, when the amplier is in operation. The POWER/PROTECTION LED (Fig. 1.1) lights up red, when the device is overheated or an error has oc- curred. After cooling down, the device should work again. If the error persists, please note the information in the section TROUBLESHOOTING.

If the amplier is to be used for mid-range/tweeter loudspeakers, set the switch X-OVER MODE (Fig. 1.3) to HP. Then set the desired crossover frequency on the HIGH PASS controller (Fig. 1.2). Thus to that only the frequencies above the chosen crossover frequency will be amplied. This effectively minimizes distortions and overloads at lower frequencies. A good point to start is at 125 Hz. If you use big loudspeakers (>20 cm) set X-OVER MODE (Fig. 1.3) to FULL. In this case, the HIGH PASS controller (Fig. 1.2) is without function.

If the amplier is to be used with a subwoofer, set the switch X-OVER MODE (Fig. 1.3) to LP/BP. Set the desired crossover frequency by using the controller LOW PASS (Fig. 1.4). Thus to that only the frequencies below the chosen crossover frequency will be amplied and the subwoofer plays more precise and efcient. In LP/BP mode, the controller HIGH PASS (Fig. 1.3) can also be used to limit the frequency response down- wards, for example to produce a bandpass/subsonic signal. CAUTION: If the controller HIGH PASS (Fig. 1.2) is set higher than the controller LOW PASS (Fig. 1.4), no audio signal is heard.14

The low level inputs on LINE INPUT (Fig. 1.6) are suitable for connecting RCA cables if your car radio has RCA preamplier outputs. Then connect the RCA sockets with the RCA cables from the car radio. A spatially separate installation, i.e. installing the power cable in the left cable duct and the RCA cables in the right cable duct of the vehicle or vice versa, is recommended to reduce interference. INPUT SENSITIVITY Turn the LEVEL INPUT controller (Fig. 1.9) counterclockwise to the MIN position. Then turn the volume control on the car radio to 80% – 90% of the maximum volume. Now slowly turn the LEVEL INPUT controller (Fig. 1.9) clockwise until you hear slight distortion from the speakers. Then turn back the LEVEL INPUT controller (Fig. 1.9) a little until you can no longer hear any distortion. BASS BOOST With the BASS BOOST controller (Fig. 1.8) you can adjust the bass level between 0-12 dB. Use this con- troller carefully to avoid distorted playback. REMOTE With the included remote, the bass level can be adjusted e.g. from the driver’s seat. Connect the remote at the REMOTE terminal (Fig. 1.7) with the included cable. The remote control should only be used when the amplier is operated in LP/BP mode with a subwoofer.

The input signal of LINE INPUT (Fig. 1.6) is passed on in stereo to LINE OUTPUT (Fig. 1.5) and enables the connection of another amplier.15 FIGURES (P. 40-43) CONNECTIONS AND CONTROLLERS (FIG. 1) (1) Status LED (2) Rotary controller for high pass / bandpass lter (3) Crossover selector switch (4) Rotary controller for low pass / bandpass lter (5) Low level output RCA jacks (6) Low level input RCA jacks (7) Terminal for the included bass level remote controller (8) Rotary controller for bass boost (9) Rotary controller for input sensitivity POWER SUPPLY AND TURN-ON CONNECTION (FIG. 2) (1) GND terminal for the ground connection (2) REM terminal for the turn-on signal from the car radio (3) +12 V terminal for the positive connection from the vehicle battery (4) External cable fuse for +12V power wire (not included in the scope of delivery) 2-CHANNEL OPERATION (FIG. 3) (1) Audio signal L from the car radio (2) Audio signal R from the car radio (3) Loudspeaker L +/- (2 – 8 Ω) (4) Loudspeaker R +/- (2 – 8 Ω) MONO OPERATION (FIG. 4) (1) Audio signal L/SUB from the car radio (2) Audio signal R/SUB from the car radio (3) Bass level remote controller (4) Subwoofer bridged R-/L+ (4 – 8 Ω) POWER SUPPLY CABLES (FIG. 5) Please note the recommendations on page 43 for the cable length and the cable cross-section of the power cables in order to ensure an adequate and safe power supply for the amplier.16 TROUBLESHOOTING

NO FUNCTION / POWER LED IS OFF

First check the fuse of the installed power cable on the vehicle battery The fuse is defective? Replace the defective fuse with one of equal value, but never with a higher value.

• The fuse fails again. In this case there appears to be a short circuit between the fuse and the device. To do this, check the entire length of the +12V power cable from the battery to the device for damage and whether there is a short circuit to ground, e.g. a contact with the vehicle chassis or 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 device.

• There is no voltage. Use the voltmeter to check the fuse located near the vehicle battery to see if there is voltage between the output and ground. If there is no voltage there, either the fuse holder or the fuse is defective, even though it appears to be okay. If necessary, replace the fuse holder or fuse.

• There is voltage. If you operate the device with a turn-on cable (REM) from the car radio to the REM connection of the device: A turn-on cable (REM) is connected to the REM connection of the device. Use the voltmeter to check whether there is voltage between the device’s REM terminal and ground. The car radio must be switched on. There is no voltage.

• Check the turn-on cable from the device to the car radio for a short circuit or damage. If necessary, replace the turn-on cable. There is voltage.

• The device is probably malfunctioning or defective. Contact your specialist dealer. If you operate the device with the speaker signals (high level mode) without turn-on cable:

• Check the speaker cables from the car radio to the device for short circuits or damage. If necessary, replace the speaker wires or insulate the damaged area.

Check the following steps: Short circuit on the speaker cables First disconnect all speaker cables from the amplier. Use a multimeter to check the ohmic impedance of each loudspeaker by measuring between its plus and minus lines. With standard loudspeakers the value uctuates between 3 and 5 ohms. The values for low-resistance subwoofers can be lower.

• The measurement shows a resistance value of less than 0.5 Ohms Then there is a short circuit. Remove the cables 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 ne, so the speaker cables appears to be defective and causing a short circuit. Replace the defective speaker cable. The measurement shows a resistance value of less than 0.5 Ohms

• The speaker appears to be defective and causes an short circuit. 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 specications of the amplier. For example, if the amplier 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 an increased ohmic resistance and thus to a voltage drop (voltage loss). This indicates that the amplier consumes more power. The increased power consumption results in a signicantly higher heat development and the amplier switches to thermal protection mode. If necessary, lay power cables with a larger cable cross-section. The amplier is overheated Every amplier requires sufcient 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 amplier or ensure better air circulation at the installation location. Turn off the sound system and wait about half an hour for the amplier to cool down again. With very hot outside temperatures and strong sunlight, enormous heat develops inside the vehicle. The amplier then activates its thermal protection circuit to prevent damage. After cooling down, the amplier works properly again.17 TROUBLESHOOTING

Slowly turn the controller down until you hear a clean audio signal. Is the loudness function on the car radio set too high? Disable loudness or turn down the loudness setting until you hear a clean audio signal. Are the EQ and sound settings on the car radio set too high? Turn down the treble, mid and bass settings or turn off the equalizer until you hear a clean audio signal. AUDIBLE NOISES (ENGINE SPEED-DEPENDENT) Check the following steps: Have the RCA cables been laid separately from the power cable in the vehicle? If necessary, re-route the cables and make sure that the RCA cables are laid separately from the power cable on the left and right of the vehicle. Is the ground connection of the device connected correctly? Make sure that the ground connection of the device is not connected directly to the negative terminal of the vehicle battery. Select a suitable ground point on the vehicle body to connect. If necessary, use contact spray to improve the conductivity of the connections. Is the conductivity of the vehicle battery ground cable 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.18 CARACTÉRISTIQUES 10 ~ 90% 5 ~ 50°C HXA100.2 Technologie Class A/B Canaux 2 Puissance de sortie RMS (14.4 V) @ 4 Ω @ 2 Ω @ 4 Ω en ponté 2 x 150 W 2 x 250 W 1 x 500 W Impédance de haut-parleurs 2 – 8 Ω Taux de distorsion harmonique @ 5 W 0.5 % Facteur d’atténuation 240 Rapport signal/brut 92 dB Sensibilité d’entrée 0.1 - 7 V Filtre passe-haut / passe-bande 10 – 250 Hz @ 12 dB/octave Filtre passe-bas / passe-bande 50 – 250 Hz @ 12 dB/octave Mode de passe-bande
