INTERCONNECTION
POWER SUPPLY AND TURN-ON-CONNECTION
First connect the GND terminal ( 3 ) of the device 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 sufficient cross-section (refer to the table below) for the power and ground connection cable. Suitable cable sets are available at the
specialist shop.
Then connect the +12 V terminal ( 2 ) of the device with the battery by using an appropriate cable including an in-line fuse (25 A). This
additional fuse (25 A) should be located very close to the battery; for safety reasons not more than 30 cm away. Only insert the fuse when
the installation has been accomplished.
Then connect the remote turn-on-wire from the head unit with the device's REM terminal ( 1 ). A cable with a cross-section of 0.5 mm
adequate.

AUTO-TURN-ON FUNCTION
The amplifier detects a voltage rise (6 Volts) with a so called "DC Offset" over the connected input signal on the HIGH LEVEL input ( 5 ) when
the head unit will be switched on. Hence, the amplifier will also be turned on. As soon as the head unit will be turned off, the amplifier turns
also automatically off. In this case the turn-on connection at REM ( 1 ) is not needed, if the switch ( 6 ) is in position ON.
Note: The Auto Turn On-function ( 6 ) usually works with 90% of all head units, because they are equipped with "High Power"-outputs. Only
with a few older and still existing head units the Auto Turn On-function is not working.
FUSE
Fuse with a rating of 25 A ( 4 ). If the fuse is defective, please replace with an equivalent fuse.
