If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of the amplifier. This works
8
in two ways, which can be set at the AUTO TURN-ON switch:
VOX: The amplifier 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 amplifier. Recommended for the use with the pre-amplifier RCA outputs of the head unit.
DC: 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. Recommended for the use with the speaker outputs of the head unit.
Note: As soon as the head unit is switched off again, the amplifier switches itself off.
The terminal for the amplifier turn-on (page 15, section 2, REM IN/OUT) can now be used to supply additional amplifiers with a
turn-on signal. Simply connect the REM terminals of the two amplifiers and make sure that the other amplifier 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:
7
LP: Low-Pass mode (fixed at 80 Hz, frequency is limited upwards).
HP: High-Pass mode (fixed at 80 Hz, frequency is limited downwards).
FULL: Full-Range mode (the entire frequency range is amplified).
The LEVEL INPUT controller determines the input sensitivity (adaptation to the output signal of the head unit). The controller
8
range is between 5 volts (MIN) and 0.2 volts (MAX).
