inputs • 2/4 CH input selector • PWM MOSFET adaptor
The four-channel universal car amplifier is suitable to drive bass speakers, middle+treble speakers and wide-
range speakers. It can be used as a 4, 3 or 2-channel amplifier. In a bridged connection, its high output power makes the
amplifier ideal to operate sub boxes and sub tubes. It has an adjustable sound switch, enabling you to set the frequency
transmission that best suits your system. To enhance bass sounds, it includes a BASS BOOST circuit.
The multiple configuration active sound switch makes the amplifier a universal solution in various scenarios. In wide-range
mode the amplifier can drive traditional car speakers, but it is also suitable to drive only bass or middle + treble speakers. The
sound switch's cut-off frequency can be adjusted between 30 - 180 Hz. I.e., in sub-bass (BASS) mode the frequency range can
be adjusted between 5 - 30 Hz and 5 - 180 Hz, and in TREBLE mode between 200 - 50,000 Hz. In wide-range (FLAT) mode the
transmitted frequency range is 5 - 50,000 Hz.
The switches and controls affect the two channel pairs in the same way.

Make sure you connect the speakers with the correct polarity. In stereo mode, use speakers with at least 2 Ohm impedance;
in a high-power bridged connection, use a speaker with at least 4 Ohm impedance. This load impedance can be realized by
connecting several speakers, but their resultant impedance must reach the specified value. The sound cables' minimum
recommended diameter is 2 x 1.5 mm2.

Use stereo cables with RCA plugs to connect the four LINE INPUT sockets to the input device (car radio, head unit
etc.). Lead the cable away from power and other speaker cords. If your car radio only has a speaker output (no low-level
line out), you can connect the high-level input labeled HI-INPUT using the included cable. If your sound source has both
options, it is recommended to use the low-level (RCA) output. You must never connect a signal to both inputs.
Set the INPUT SELECTOR switch to the desired position corresponding to your setup (2 or 4 channel input).
The device needs power over three connectors. The length of the +12 V wire between the battery and the external fuse
socket (not included) should not exceed 50 cm. Locate the fuse socket as close to the battery as possible. The ground wire
should also be as short as possible.
Connect the negative pole first. It is very important that this connection have a perfect ground contact. An imperfect
connection can cause noise and malfunction. The minimum diameter of the power cords is 6-10 mm2. (REM cable: min.
0.75 mm2)

* If your car radio does not have a 12 Volt output for this purpose, connect this point to the +12V power voltage. In this case,
it is recommended to either install a switch before the remote control input, or to connect the control voltage to a point that
is powered off when the ignition key is removed. Otherwise the amplifier will be permanently on, putting a drain on the battery.
Before powering up the amplifier verify that it is connected correctly. Connections should be stable and without short circuits,
and the switches and controls should be in the correct position.
A green POWER / PROTECTION light indicates that the amplifier is on; red means that the protective circuits are active. The
latter indicates that the amplifier is malfunctioning, overloaded, or incorrectly connected. In that case, disconnect the amplifier
from the power immediately.
If the green LED is not lit up at all, disconnect the amplifier, disconnect the speakers and the car radio, and power up the
amplifier again. If the light is still off, use a voltage meter to make sure that the amplifier does in fact receive the 12 V
power, and that the ground connection is stable. If the car radio has a separate remote control output and you connected it
(REMOTE), also verify the presence of the control signal.
Connecting the power, the car radio and the speakers again one by one you can identify the faulty unit or cable. If needed, also
verify that the fuse(s) are in good condition.
If the system emits noises, turn the volume down, and first unplug the RCA connectors. If you still hear the noise, make sure
the amplifier is correctly grounded.
If the noise stops, that means the source is outside the amplifier. Possible causes include: a ground loop, a contact fault in
the head unit's ground, at the audio processor, at the sound switch, or at another device in the audio frequency chain. A faulty
circuit breaker, old battery, damaged ignition cables or faulty contacts can all be sources of audible noise.
Set the GAIN control to MIN. Turn on the car radio and set its volume control to approximately 3/4. Slowly start turning the
GAIN button clockwise until you start to hear distortion at the acoustic peaks. Then turn it counter-clockwise a little. This will
be the system's maximum volume which is emitted in good quality without distortion. The correct GAIN setting depends on the
signal level of the car radio's output, and may vary from type to type.
By further increasing the GAIN level the system's output power does not increase any further; instead, the maximum usable
volume on the car radio becomes lower because the system's distortion grows. A distorted signal can damage the speakers.
• Installing a car hi-fi system requires important professional skills and experience, which are not covered in this manual.
If needed, consult a technician to avoid damaging your system or the vehicle. Proper installation is essential for the
system's reliable operation.
• The warranty is not applicable to damage caused by improper installation or connection.
• Never cover the device and only install it in a location with proper ventilation.
• Protect from sunlight, humidity and water.
• The speaker's poles must have no connection to each other or the car's body (negative pole).
• Especially when the temperature in the amplifier's environment is extremely high or low (e.g., when the car is parked in
direct sunlight in the summer, or at freezing temperatures in the winter) the automatic protective circuit may become
active and turn off the amplifier. In that case, leave the amplifier turned off until normal environment temperature is
restored.
• Do not use the amplifier for a long time when the engine is not running, as that may drain the battery.
• Always listen to your sound system at a volume that does not disturb your participation in traffic and does not damage
your hearing. Many car hi-fi systems are capable of emitting sound pressure over 130 dB. However, levels above 100 dB
can damage your hearing permanently.
• When replacing the fuse, always use an identical type.
• This device can only be used with a 12 Volt power source where the negative pole is grounded.
• Clean with a soft, dry cloth.

Der universeller Vierkanal-Autoverstärker ist für den Antrieb Tief-, Tiefmittel- + Hoch, und Breitbandlautsprecher
geeignet. Kann sowohl als 4-, als 3- und auch als 2-Kanal-Gerät verwendet werden. Er ist gebrückt geschaltet ideal für den
Betrieb von Bassreflexgehäusen und –Röhren. Die Frequenzweiche ist regelbar, es kann für das gegebene System am besten
angepasster Frequenzgang eingestellt werden. Zur Verstärkung der Basswiedergabe wurde auch mit einem BASS BOOST
Stromkreis versorgt.
Die Grundlage der universellen Verwendbarkeit des Gerätes ist die umschaltbare aktive Frequenzweiche. Durch Hilfe deren
ist der Verstärker fähig in Betriebsart Breitband herkömmliche Autolautsprecher anzutreiben, aber auch ausschließlich Tief-
oder Tiefmittel- + Hochstrahler. Der Schnittpunkt der Frequenzweiche kann zwischen 30 – 180 Hz, bzw. geregelt werden.
Das heißt, der Frequenzgang kann in Betriebsart Sub-Bass (BASS) zwischen 5 – 30 Hz und 5 – 180 Hz verstellt werden, in
TREBLE-Stellung zwischen 200 – 50.000 Hz. Beim Breitband-Betrieb (FLAT) wird der Frequenzgang zwischen 5 – 50.000 Hz
liegen.
Die Schalter und Regler beeinflussen den Betrieb beider Kanal-Paare gleichermaßen.

: gebrückter Anschluss (mono) der beiden hinteren Kanäle
Mit der Überschrift LINE INPUT versehene 4 Cinch-Buchsen und die Tonquelle (Autoradio, 'Head Unit', …) wird
mit einem Stereokabel versehen mit Cinch-Stecker verbunden. Halten sie diese Leitung fern von den Strom- und
Lautsprecherkabeln. Wenn das Autoradio ausschließlich mit Lautsprecherausgängen versehen ist, d.h. besitzt es keine
Niedrigpegel-Ausgang, dann kann der HI-INPUT Hochpegel-Eingang mittels des beigelegten Anschlusskabel verwendet
werden. Wenn es bei der Signalquelle beide Möglichkeiten gegeben sind, empfiehlt sich den Niedrigpegel-Ausgang
(Cinch) zu benutzen. Es ist verboten beide Eingänge des Verstärkers gleichzeitig anzuschließen!
Stellen sie der gewünschten Verwendung entsprechend den Eingangs-Wahlschalter INPUT SELECTOR ein (2-oder
4-Kanal Eingang)
Das Gerät soll die Spannung zum Betrieb durch drei Klemmen bekommen. Die Leitungsstrecke (+ 12 V) zwischen der
Batterie und der äußeren Sicherungsfassung (nicht im Lieferumfang) darf nicht länger als 50 cm sein. Auch die Erdleitung soll
möglichst kurz gehalten werden.
Schließen sie erst den negativen Pol an. Es ist äußerst wichtig, dass dieser Anschluss besonders guten Masse-Kontakt
habe. Ein Fehler dessen kann zu Geräusch, Verzerrung, fehlerhafte Funktion führen. Die Stromkabel sollen mindestens einen
Querschnitt von 6 – 10 mm2 , der REM-Kabel mindestens 0,75 mm2 haben.
