INTERCONNECTION
First connect the GND terminal ( 2 ) of the power plug to an appropriate ground connection at the chassis. To ensure a good connection,
remove dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion.
Use at least a 10 mm2 cross-section for the power and ground connection cable. Suitable cable sets are available at the specialist shop.
Then connect the +12 V terminal ( 1 ) of the power plug 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, inclu-
ding the connection of the loudspeakers, has been accomplished.
Then connect the remote turn-on-wire (Remote) from the headunit with the power plug‘s middle connector ( 3 ). A cable with a cross-section
of 0.5 mm2 is adequate.
POWER SUPPLY AND TURN-ON-CONNECTION
With this function the amplifier detects a voltage rise over the connected input signal on the AUDIO INPUT ( 4 ) when the headunit will be
switched on. Hence, the amplifier will also be turned on. As soon as the headunit will be turned off, the amplifier turns also automatically
off. In this case the turn-on connection ( 3 ) is not needed, if the switch ( 5 ) is in position DC OFFSET or AUDIO.
The DC OFFSET mode is the best choice for the Auto Turn On-function and usually works with 90% of all headunits, because they are
equipped with ”High Power”-outputs. Only with a few older and still existing headunits are working only with the AUDIO mode.

OPERATING ELEMENTS
The input sensitivity can be adjusted to any headunit. Turn the volume control of your headunit to the center medium position
and then adjust the input level controls ( 9 ) until you have an average medium level. This setting usually provides sufficient
power reserves at optimum weighted signal-to-noise ratio.
INPUT SENSITIVITY
Set the desired crossover frequency of the low pass filter by using the controller ( 10 ). Hence, only the frequencies below the
chosen crossover frequency will be amplified and the subwoofer plays more precised and efficient.
VARIABLE LOWPASS FILTER
By using the boost controller ( 11 ) you are able to increase the bass boost level from 0 dB to 12 dB.
Caution: Please use the bass boost with care.
VARIABLE BASS BOOST
Remote jack ( 13 ) for the included bass remote controller. If the bass remote controller is connected it replaces the GAIN con-

1. Check the fuses of the device or the external fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary.
Please ensure that you have reconnected the GND connection at the battery after the installation.
3. Verify that there are 11 to 15 Volts present at the positive battery and remote turn-on cable. Verify quality connections for both cables at device,
headunit and battery/fuseholder. Repair/replace if necessary. Check that the vehicle charging system is maintaining proper voltage.
Procedure 2:
The LED ( 7 ) lits up red.
1. If the LED lits up red, this is a sign of overheating and driving the device at very high power levels without adequate airflow around the device.
Shut off the system and allow device to cool down. If the previous items do not solve the problem, a fault may be in the device.
Check that the vehicle charging system is maintaining proper voltage.
Procedure 3:
Check the device for a proper audio signal.
1. Verify good RCA input connections at headunit and device. Check entire length of cables for kinks, splices, etc.
Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.
2. Use another audio source for testing to provide an audio signal to the Line Input.
3. If you use high level speaker inputs, check the polarity.
Procedure 4:
Check the device for a popping noise while turning on.
1. Disconnect input signal to device and turn device on and off.
2. If the noise is eliminated, connect the REMOTE lead of device to source unit with a delay turn-on module.
OR
1. Use a different 12 Volt source for REMOTE lead of the device (e.g. battery direct just for testing).
2. If the noise is eliminated, use a relay to isolate the device from noisy turn-on output.
3. Don‘t connect REMOTE directly to the battery after testing to avoid a discharge of the battery.

ANSCHLÜSSE
Stellen Sie zunächst eine Verbindung zwischen dem GND-Anschluss ( 2 ) des Stromanschlusssteckers und einem geeigneten Masse-Anschluss-
punkt an der Fahrzeugkarosserie her. Um eine gute Verbindung zu garantieren, sollten Schmutzreste sorgfältig vom Masse-Anschlusspunkt ent-
fernt werden. Ein lockerer Anschluss kann eine Fehlfunktion oder Störgeräusche und Verzerrungen zur Folge haben. Verwenden Sie für den Strom-
und Masseanschluss ein Kabel mit einem Querschnitt von min. 10 mm2. Geeignete Anschluss-Sets erhalten Sie im Fachhandel.
Der +12 V-Anschluss ( 2 ) des Steckers muss nun mit einem ausreichend dimensionierten Stromkabel mit integrierter Sicherung mit dem Pluspol
der Fahrzeug-Batterie verbunden werden. Die externe Sicherung sollte sich in Nähe der Batterie befinden, die Kabellänge vom Pluspol der Batterie
bis zur Sicherung muss aus Sicherheitsgründen unter 30 cm liegen. Setzen Sie die Sicherung erst nach Abschluss aller Installationsarbeiten ein-
schließlich der Lautsprecher-Anschlüsse ein.
Schließen Sie nun die Einschaltleitung (Remote) des Steuergeräts bzw. Autoradios an den mittleren Anschluss ( 3 ) des Stromanschlusssteckers
an. Für diese Verbindung ist ein Kabel mit einem Querschnitt von ca. 0,5 mm2 ausreichend.
STROMVERSORGUNG UND EINSCHALTLEITUNG
Mit Auto-Turn-On (Automatische Einschaltfunktion) erkennt der Verstärker an den Audioeingängen (AUDIO INPUT, 4 ) einen Spannungsan-
tieg, wenn das Steuergeräte angeschaltet wird und schaltet sich automatisch mit ein. Sobald das Steuergerät wieder abgeschaltet wird,
schaltet sich der Verstärker ab. Der Anschluss für die Einschaltleitung (Remote, 3 ) ist in diesem Falle ohne Funktion und muss nicht belegt
werden, wenn der Schalter (AUTO TURN ON, 5) auf DC-OFFSET oder AUDIO steht.
DC-OFFSET ist der bessere Modus und funktioniert prinzipiell mit 90% aller Steuergeräten, da diese ”High Power”-Ausgänge besitzen. Nur
einige wenige älteren Autoradios funktionieren nur mit dem Modus „AUDIO“.
