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 controls (3) and
(4) 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
If the amplifier is used as a subwoofer amplifier, set the switch (9)/(10) to "LPF". Set the
desired cross-over frequency using the control (7)/(8). 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 HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY
If the amplifier is to be used as an amplifier for satellite loudspeakers (mid-range/tweeter
loudspeakers), set switch (9)/(10) to "HPF". Set the desired cross-over frequency using
the control (11)/(12). Only the frequencies above the set cross-over frequency will then
be amplified. This effectively minimizes distortions caused by excessive membrane
movement at low frequencies and small satellite loudspeakers without reducing the bass
level.
5.4 BASS-BOOST
The bass-boost function (5/6) is used to increase or equalize the lower bass frequencies.
5.5 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS
The input signal of the LINE INPUT connections CH1, CH2, CH3, CH4 (1 and 2, Fig. 7)
is accumulated and forwarded directly to the LINE OUT (14) jacks. The LINE OUT
connections allow the use of a subwoofer amplifier without requiring additional T-plugs
and cables.
