The LEVEL INPUT controller determines the input sensitivity (adaptation to the output signal of the head unit). The controller
range is between 5 volts (MIN) and 0.2 volts (MAX).

If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of the amplier. This works
in two ways, which can be set at the AUTO TURN-ON switch:
VOX: The amplier then detects a voltage increase in the incoming audio signal when switching on the head unit via the attached
RCA cable and then switches on the amplier. Recommended for the use with the pre-amplier RCA outputs of the head unit.
DC: The amplier 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 amplier. Recommended for the use with the speaker outputs of the head unit.
Note: As soon as the head unit is switched off again, the amplier switches itself off.
The terminal for the amplier turn-on (page 15, section 2, REM IN/OUT) can now be used to supply additional ampliers with a
turn-on signal. Simply connect the REM terminals of the two ampliers and make sure that the other amplier is in “normal” turn-
on mode, which means that the AUTO TURN ON function is disabled.

The X-OVER switch selects the desired operating mode:
LP: Low-Pass mode (xed at 80 Hz, frequency is limited upwards).
HP: High-Pass mode (xed at 80 Hz, frequency is limited downwards).
FULL: Full-Range mode (the entire frequency range is amplied).
