5. OPERATING ELEMENTS AND IN/OUTPUTS
5.1 SETTING THE INPUT SENSITIVITY
The input sensitivity may be adapted to any car radio or tape deck. Turn the volume control of your radio
to its central position and then adjust the input-level control (3) to produce an average medium volume.
This setting usually provides sufficient power reserves at optimum weighted noise voltage.
ATTENTION: only reproduce loud test noises briefly to prevent damaging the loudspeakers.
5.2 LOW-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY
Set the desired cross-over frequency with the control (5). This makes the filter adaptable to the installed
woofer's sound requirements. The filter's high edge steepness is responsible for the precision reduction
of medium and high frequency ranges.
5.3 SUBSONIC FILTER
The subsonic function reduces the lowest bass frequencies. The reduction rate may be infinitely adjusted
with the regulator (4). This allows distortions produced by excessive loudspeaker membrane movements
to be effectively minimized without reducing the utilizable bass levels.
5.4 BASS-BOOST
The bass-boost function (6) is used to increase or equalize the lower bass frequencies.
5.5 VOLUME REMOTE CONTROL
The volume may be adjusted by using the supplied remote control. Please observe during installation that
the remote control line shouldn't be routed along the same side of the vehicle as the power supply cables.
The remote control unit should be mounted on the dashboard or at any other easily accessible position.
Now, the subwoofer volume may be adjusted independently from the settings at the radio.
5.6 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS
The input signal of the INPUT connections INPUT L and R (1) is forwarded directly to the OUTPUT (2) L
and R jacks. The OUTPUT connections allow the use of additional amplifiers without requiring additional
T-plugs and cables.
FIG. 1 POWER SUPPLY / REMOTE SWITCH-ON CONNECTION
(1) GND terminal for the ground, to the battery's minus pole
(2) REM terminal for remote switch-on
(3) Terminal for +12 V battery voltage
(4) Battery
(5) Cable fuse
(6) To your car radio's automatic aerial connection
If your car is not equipped with an automatic aerial connection, connect this cable's plus pole (+)
to the ignition lock. An on/off switch should be inserted in this case. Make sure that this switch is
switched off if the amplifier is not used.
