HIGH LEVEL INPUT
If your head unit does not have RCA preamp outputs, you can use the HIGH LEVEL INPUT. Connect
the loudspeaker cables of the head unit to the included cable harness.
16
AUTO TURN-ON
If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of
the amplifier. The amplifier then detects a voltage rise to 6 volts when the head unit is turned on by a
so-called “DC offset” and then turns on the amplifier. As soon as the head unit is switched off again,
the amplifier switches itself off.
17
POWER/PROTECT
If the LED lights up in blue, the amplifier is ready for operation. If the LED lights up in red, there is a
malfunction. Refer in this case to chapter TROUBLE SHOOTING on page 26.
14
CLIP LED
The CLIP LED lights up when the input signal is overloaded. Then turn the LEVEL controller (see sec-
tion 8) back accordingly until the LED goes out.
