REAR X-OVER MODE
13
This switch selects the desired operating mode of channel pair REAR:
FULL: Full Range mode - the entire frequency range is amplified
HP: High Pass mode adjustable with HIGH PASS - frequency is limited downwards,
LP/BP: Low Pass mode adjustable with LOW PASS - frequency is limited upwards,
The HIGH PASS controller acts as a Bandpass filter and limits the frequency downwards.
Note: If the HIGH PASS controller is set higher than the LOW PASS controller, no sound is heard.
14 LOW PASS
This controller limits the frequency at the respective channel pair upwards. The crossover frequency
at REAR is adjustable from 50 Hz to 5000 Hz (5 kHz) and on SUBWOOFER from 40 Hz to 150 Hz.
15 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. This works in two ways, which can be set at the AUTO TURN-ON switch:
DC: This method only works if you use the HIGH LEVEL INPUT wiring harness. The button switch
INPUT LEVEL must be in position HIGH. 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.
VOX: Select this method when using the RCA jacks of the RCA wiring harness. The button switch
INPUT LEVEL CH1-6 must be in position LOW. 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.
Note: As soon as the head unit is switched off again, the amplifier switches itself off.
The terminal for the amplifier turn-on (Refer to page 6, section 2) 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.
SUB SONIC
16
This controller limits the ultra low and not audible frequencies of the audio signal of the channel pair
SUBWOOFER downwards to avoid mechanical and electrical overloading on the subwoofer. The
crossover frequency is adjustable from 10 to 40 Hz and depends on the size of the subwoofer.
BASS BOOST
17
This controller adjusts the bass boost from 0 dB to +12 dB at 45 Hz at channel pair SUBWOOFER.
PHASE SHIFT
18
This controller allows to adjust the phase between 0° and 180°of the channel pair SUBWOOFER. This
allows that the running time of the subwoofer signal can be matched to the full-range loudspeakers.
Set the controller so that all signals arrive in the acoustic center at the same time.
19 BLC REMOTE
The BLC REMOTE port is for connecting the cable of the included bass level remote controller. With
this, the bass level at the channel pair SUBWOOFER can be e.g. be adjusted from the driver's seat.
Only use the supplied bass remote controller and the associated cable.
