Power supply connections

3.4.1 Ground cable
The ground cable must be permanently connected to the metal of the vehicle chassis. During
the connection process, please ensure that the metal of the vehicle chassis is bright and free
from paint residues. Good grounding constitutes the basis for a high audio quality of the entire
system. The best solution is to connect the ground cables of all audio components (car radio,
amplifier, equalizer, etc.) to one common place of the vehicle's chassis. Connect the ground
cable to the screw terminal labeled „GND".
3.4.2 +12V Power cable
Run a power cable from the battery to the amplifier; use appropriate cable size. You have to
install an additional fuse within 20 centimeters distance from the battery. Keep in mind that
the fuse also has to protect the vehicle against possible electrical fires caused by short
circuits. Inserting the fuse should be the last installation step in any system before initial
power up.
The +12V power cable must be directly connected to the positive terminal of the battery, not
to the electrical system of the car.
3.4.3 Remote-turn-on-cable
The remote-turn-on-cable is connected to the "Remote" connection or to the "Automatic
antenna" connection of the radio unit. The latter is only activated when the radio is switched
"ON". Therefore, the amplifier is switched off if remote is not activated and this saves the
battery.

Signal Connection

3.5.1 Input
The inputs serve to connect to an audio source with preamp level outputs. Use heavy-duty
RCA patch cords designed for mobile applications.
Run the patch cables carefully, maintaining as much distance as possible from power,
speaker, and accessory wiring. Make sure the RCA plugs fit tightly for a secure connection.
SIGNAT amplifiers feature BIC (Balanced input circuitry). The input sensitivity of the amplifier
can be adjusted to the output voltage of your radio using the "GAIN" control.
Remark:
Please avoid any use with "open" (disconnected) input jacks; BIC requires a properly
connected input to the audio source.
