IMPORTANT NOTES PRIOR TO INSTALLATION

- This device is only suited for a 12 volt system with negative ground.

- The radiated heat while operation requires sufcient air circulation at the place of installation. It is

very important that the heat sink ns do not have contact with any metal parts or any surfaces which

could impair air circulation. The amplier may not be installed in small closed location or spaces

without air circulation (e.g. spare wheel recess or below the vehicle carpeting). We recommend the

installation in the vehicle’s trunk. Ensure sufcient protection against vibrations, dust and dirt.

- Ensure that the input and output cables are sufciently separated from the power supply cables.

Otherwise interferences may occur.

- Ensure the accessibility of the fuse and the operating elements after installation.

- The reliability and performance of the amplier depends on the quality of installation. Preferably

consult an expert to install the system, particularly if you want to install several loudspeakers.

POWER SUPPLY AND TURN-ON-CONNECTION

ATTENTION: Before you start with the installation, disconnect the ground connection from the ve-

hicle’s battery in order to prevent short circuits.

The power wiring which is usually installed in on-board car networks is not sufcient for a power amplier‘s

demands. Make sure that the power wires to GND and to the +12 V terminal has been sufciently specied. A

cable cross section of at least 10 mm

must be used to connect the battery to the amplier‘s terminals.

First connect the GND terminal of the amplier to an appropriate ground connection at the chassis. To ensure a

good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions

or interferences noise and distortion.

Then connect the +12 V terminal of the amplier 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, including the connection of the loudspeakers, has been ac-

complished.

Then connect the remote turn-on-wire from the head unit with the amplier‘s REM terminal. A cable with a

cross-section of 0.5 mm

is adequate.

LOUDSPEAKER CONNECTION

- In 4-channel operation (i.e. one loudspeaker on each amplier channel), the impedance must

not be lower than 2 ohms for each speaker

- In bridging mode (two amplier outputs combined) the impedance must not be lower than 4 ohms

for the bridged output.

- Never connect loudspeaker cables with the ground of the chassis or the +12 V supply voltage.

If the amplier is operated with a too low impedance or incorrectly used, the entire sound system may be dam-

aged. This means a warranty void in such cases.

AUDIO SIGNAL CABLES

When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the ampli-

er (Fig. 1,5), the audio and power supply cables should, if possible, not be routed along the same side of the

vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on

the left side and the audio cables through the cable channel of the vehicle on the right side or vice versa. This

prevents interferences due to crosstalk into the audio signal.
