Setup
To ensure the correct initial operation, please read these operating instructions and the safety instructions carefully before using the appliance!
Mechanical Installation
Modifications to the vehicle which are made necessary through the installation of the amplifier or other components must always be carried out in such a manner that neither the traffic safety nor the designed stability of the car is impaired. For many cars, the operating license lapses already if you saw out a part of metal.
If you are in doubt when selecting a place for installation, consult your car dealer.
Since the amplifier generates heat the place of installation must be resistant against heat.
To ensure an adequate ventilation, there must be an open area of 5cm around the housing. Apart from this, the air circulation may not be obstructed by objects such as magazines, blankets, covers or similar.
Before drilling the attachment holes make sure that the electric cables, brake lines, the fuel tank or similar systems will not be damaged.
If using tools to install your car hi-fi components, observe the manufacturer's safety instructions.
When installing the car hi-fi system, consider the danger of accident which can arise by devices broken away in the case of an accident. Therefore, fasten each part reliably and at a place at which it cannot become a risk for the passengers.
Select a suitable position for mounting the amplifier.
A suitable place for mounting has the following features:
dry
- as free from dust as possible
- little vibration
good circulation
heat-resistant environment
Good places for installation are the luggage boot and the free space under the seats. Make sure that the amplifier can be accessed in such a way that it can be connected to the electrical system.
A favourite place of installation is also the bulkhead between the luggage boot and the passenger compartment.
- Mark the holes for the screws at the place of installation. For doing this, use the device as a pattern.
- Drill the holes for the fastening screws.
- Fasten the amplifier by the two screws delivered.
Connecting the Power Supply
The electric connection should always be performed by a specialist.
To avoid short circuits and resulting damages to the de vice the negative terminal (ground) of the car battery is to be disconnected first.
Before reconnecting the negative terminal to the battery, ensure that the amplifier has been completely connected.
You should only use a voltmeter or a diode test la mp for checking the voltage applying at car cables, because normal test lamps consume too high currents and thus can damage the electronic system of the car.
When installing cables make sure that the connection cables are not squeezed or damaged by sharp edges. Use rubber bushings for passing points.
In order to reduce parasitic induction of the generator or of other electric systems of the vehicle, the amplifier should be directly powered by the car battery. It is not allowed to supply other electric loads, such as the cooling fan, the windscreen washer etc., via the same cable as the amplifier.
Use connection cables with a possibly large cross-section for connecting the power supply and the ground of the amplifier. The necessary cross-section of the cable depends on the power requirements of the components connected.
A cross-section of the cables that is too small can cause a cable to char through in the worst case. Moreover, the increased ohmic resistance leads to unnecessary power losses.
An additional fuse in the positive connection of the amplifier is necessary in any case (fuse holder is not included in the scope of delivery). The fuse should be installed close to the battery. In case of short circuit (e.g. if the connection cable is worn through) the fuse disconnects the positive lead and thus avoids a damage of the battery and prevents the supply cable from burning.
The strength of the fuse depends on the power consumption of the connected devices of the car hi-fi system.
Connect the "+" connector of the connection terminal of the power supply directly to the positive terminal of the car battery.
Connect the "REMOTE" connector to the terminal on the power supply, to the remote control connector or to the antennae control output of the car radio.
Connect the "GND" connector of the connection terminal for the power supply to the negative terminal (ground) of the battery or to the car body.
The amplifier will be switched on via this input, if a voltage of +12V is applied.
Nowadays, almost all car radios are provided with such a control output which only carries +12V if the radio is turned on.
Attention! Since the electrical conductivity is continuously limited due to the increasingly used gluing technology or the lacquered metal parts, not each metal component is suited to function as a mass point.
Distribute the power supply in a star-shaped way, i.e. the connections of the negative leads start from one and the same point for all components of the car hi-fi system. This way of distributing the power supply avoids mass loops.
Connect the positive leads in the same way.
Connecting the Inputs
Model XCA XCA 400 and XCA 402
The amplifier is provided with cinch inputs to be connected to the car radio.
Car radios with cinch outputs can be directly connected to the input sockets. If your car radio is only provided with loudspeaker outputs, a suitable audio frequency adapter is to be used for the connection.
Model XCA 200 and XCA 202
The amplifier has both loudspeaker and cinch inputs to be connected to the car radio.
If your car radio has cinch outputs, the amplifier should be connected via the cinch inputs in any case to ensure a high playback quality.
But if your radio car is not provided with cinch outputs, you can connect the amplifier to the loudspeaker outputs without requiring any additional devices or adapters.
Never use the two input types (loudspeaker and cinch inputs) simultaneously.
For connecting the cinch inputs, use only shielded cinch cables suitable for this purpose. The use of any other cable may cause interference.
Keep the length of the connection cables as short as possible.
Do not install the cables in the proximity of other cables. Thus, you avoid interface at the amplifier input.
To avoid distortion or mismatches that could lead to the power amplifier being damaged, only sources with a cinch plug should be connected to the cinch inputs and only speaker outputs should be connected to the speaker inputs of the models XCA 200 and XCA 202. Please, also pay attention to the connection loads in the "Technical Data".
Model XCA 400 and XCA 402
Connect the cinch outputs of your car radio to the cinch connections IN (7) of the amplifier.
rear outputs > connection REAR IN
front outputs > connection FRONT IN
Pay attention to the marking on the cinch connections:
L > left
R > right
If your car radio does not have 4 pre-amplifier outputs please use the so called Y-adapter.
Connection via the cinch inputs
Connect the cinch outputs of your car radio to the cinch connections IN (7) of the amplifier.
Pay attention to the marking on the cinch connections:
L>left
R > right
Connection via the loudspeaker inputs
Plug the delivered loudspeaker connection cable into the connection HIGH IN (9) of the amplifier.
Connect the loudspeaker outputs of your car radio to the terminals of the loudspeaker connection cable.
L+ connection > left positive loudspeaker output
L- connection > left negative loudspeaker output
R- connection > right negative loudspeaker output
R+ connection > right positive loudspeaker output
Connecting the Outputs
Connecting the Loudspeaker Outputs
The power amplifier is supplied with outputs for 4 model XCA 400 and XCA 402 speakers or for 2 model XCA 200 and XCA 202 speakers.
Each of the 2 loudspeaker outputs can also be used in the mono-bridge mode. In fact, only one loudspeaker is powered in this mode, but the available output voltage is higher.
Moreover, one cinch output remains for triggering other system components.
The loudspeakers must be connected with double wires. Insulate The loudspeakers must be connected with double wires. Insulate the naked wire at connecting terminals. Make sure that there are no harp edges which may damage the cables.
Only use loudspeakers which have a sufficiently high loading capacity (see „Technical Data").
Make sure that the loudspeakers have been connected in the correct polarity, i.e. plus and minus signs harmonize!
The connection cables of the loudspeakers are normally coded: Some loudspeaker manufacturers indicate the (+) wire by means of an additional colour stripe, others use a corrugated cable for the (+) terminal and a smooth one for the (-) terminal.
This amplifier has been designed for a loudspeaker impedance of at least 2 ohms (stereo mode) or 4 ohms (mono-bridge mode). Never connect loudspeakers with a lower impedance.
Depending on the model and mode of operation, connect the loudspeaker outputs according to the following schemes. Observe the minimum impedance given for the corresponding mode of operation.
Stereo mode XCA 400 and XCA 402 model
Minimum loudspeaker impedance of 2 ohms
Stereo mode XCA 200 and XCA 202 model
Minimum loudspeaker impedance of 2 ohms
Mono-bridge mode XCa 400 and XCA 402 model
Minimum loudspeaker impedance of 2 ohms (stereo loudspeaker pair) and 4 ohms (subwoofer)
or
Minimum loudspeaker impedance of 4 ohms
Mono-bridge mode XCA 200 and XCA 202 model
Minimum loudspeaker impedance of 4 ohms
Connecting the cinch outputs
Additionally to the loudspeaker outputs, the amplifier is provided with cinch outputs by means of which the input signal can be fed to other components of the car hi-fi system without using adapters.
For connecting the cinch outputs, use only shielded cinch cables suitable for this purpose. The use of any other cable may cause interference.
Keep the length of the connection cables as short as possible.
Do not install the cables in the proximity of other cables. Thus, you avoid interface at the input of the subsequent component.
To avoid distortion or mismatching which could damage the amplifier or the subsequent component, only devices with cinch inputs may be connected to the cinch outputs.
Connect the connection OUT (8) with the input of the subsequent component.

Operation
Active Duplexer
Model XCA 400 and XCA 402
The amplifier is provided with an active duplexer which allows to switch a high-pass or a low-pass branch for the rear channels. One high-pass branch is provided for the front channels.
The cut-off frequencies can be continuously adjusted.
The amplifier is provided with an active duplexer which allows to switch a high-pass or low-pass branch for the two channels.
The cut-off frequencies can be continuously adjusted.
The frequency duplexer switch X-OVER (4) sets the operating mode of the active duplexer.
FULL:
Active duplexer switched off, the amplifier branch plays back the complete frequency range
HPF:
High-pass duplexer switched on, the amplifier branch only plays back the frequency range above the frequency set via the HPF (1) control unit.
LPF:
Low-pass duplexer switched on, the amplifier branch only plays back the frequency range below the frequency set via the LPF control unit (2).
Super Bass Switch
In addition to this, the amplifier has a bass-boost switch to amplify the low-bass frequencies in two stages.
This option is especially useful to give smaller bass loudspeakers or subwoofoers a little bit of more volume in the low-bass range.
The SUPER BASS
(6) controls the low-bass amplification
Position "0dB":
low-bass amplifier is turned off
Position "6dB":
Low bass is amplified by 6dB
Position "12dB":
Low bass is amplified by 12dB
Initial Startup
After installing and checking all the necessary cable connections you can set the amplifier into operation.
If you have checked the cable connections, reconnect the negative terminal of the battery.
Turn the GAIN control unit (3) counter-clockwise to minimum.
Slide the frequency duplexer switch(es) X-OVER (4) into the position corresponding to your configuration.
Set the cut-off frequencies for the connected loudspeakers via the HPF (1) and LPF (2) control units.
See „Active Filter“
The cut-off frequencies can be set continuously within a range of 50-250Hz or 80-2,000Hz.
During setting operation pay attention to the frequency data given by the loudspeaker manufacturer.
Switch on your car radio.
The indicator LED POWER (5) does light up. If the indicator LED PROTECTION (5) lights, an error has occurred. The amplifier is to be
switched off immediately. In this case, check all connections and loudspeakers. If you cannot detect an error, please contact a specialist for help.
If the indicator LED POWER (5) lights up, set the volume of the car radio to about 75% of the maximum volume.
Now, use the X-OVER control unit(s) (3) to adjust the maximum volume of the loudspeakers to a value which is acceptable for you. If you use several amplifiers, match the volumes of the different amplifiers one to the other.
Then, set an average volume level via the volume control unit of the car radio.
To reach an optimum sound, you can slightly adjust the set cut-off frequencies via the HPF (1) and LPF (2) control units.
If the low-bass playback is too weak, you can activate a two-stage low-bass amplifier via the SUPER BASS switch (6).
Take care that the maximum volume depends on the power capacities of the loudspeaker and amplifier. Excessive volume can damage the loudspeakers and amplifier.
A timing signal can be heard in case of overload.
From now, the total volume is only set by the volume control unit of the car radio.
Make sure that the frequency ranges indicated by the loudspeaker manufacturer are not exceeded during setting operations.
If you use a subwoofer, the change of polarity of the loudspeaker connecting cables may improve the sound quality. Often, the reverse terminal position causes a better bass playback (depending on the place of installation of the subwoofer).
See „Super Bass Switch“
Handling
- An excessive volume inside the car can lead to the reaction that acoustical warning signals are not be heard any longer. This can mean that you and other road users are endangered. Therefore, pay attention to a suitable volume.
- Inattentiveness in traffic can lead to serious accidents. Therefore, the hi-fi system may only be used if the traffic situation allows its operation and if you are not distracted from the traffic by the system.
- The amplifier must be ventilated sufficiently. Never cover the cooling ribs.
- Do not listen to excessively loud music for long periods of time. This can damage your hearing.
Maintenance
Check the technical safety of the amplifier regularly, e.g. for damage to the connection cables or to the housing.
If it can be assumed that a safe operation is not possible any longer, the product must be turned off and precautions are to be taken to ensure that it is not used unintentionally. Disconnect the car power system!
It can be assumed that the safe operation is no longer possible:
- if there is visible evidence that the device has been damaged
- if the appliance does not function for some reason, or
- following considerable stress during transportation.
Observe the following safety instructions without fail before cleaning or servicing the amplifier:
Live components may be exposed if the covering is opened or components are removed.
Therefore, the amplifier must be disconnected from all voltage sources before carrying out servicing or repair works,
Capacitors in the appliance may still be charged even after disconnecting them from all power sources.
Repair work must always be carried out by qualified experts familiar with the hazards involved and with the relevant regulations.
If you have to replace fuses, ensure that you only use fuses of the same type and rated current (see "Technical Data").
It is absolutely impermissible to repair fuses or bridge the fuse holder.
- After disconnecting the appliance from the power source (by disconnecting the car power supply!), carefully remove the FUSE fuse from the fuse holder.
- Replace it by a fuse of the same type.
- Only then the amplifier should be re-connected to the car system and operated.
