Highpass Filter; Lowpass Filter - Signat ROM2 Bedienungsanleitung

CAUTION: the amplifier must be installed correctly, and connected to the source and
any other components normally used in the system. Never insert anything metallic into
any openings of the amplifier. For ENS adjustment, only use a small, non
metallic, blade type screwdriver that will fit though the opening.
Recommended adjustment of ENS:
1. With the system turned off, disconnect the main speakers from the channel you are going
to fine tune
2. Mark the position(s) of the „LEVEL" control(s) for the channel(s) you are going to fine
tune.
3. Turn the „LEVEL" control(s) fully CW for the channel(s) you are going to fine tune.
4. Connect a small test speaker to the channel you want to adjust.
5. Make sure the source unit volume is fully CCW (min).
6. Start the engine, and turn on the system
7. Use a small plastic screwdriver to adjust ENS for the channel the test speaker is
connected to. Listen to the speaker, and adjust for the minimum noise level.
8. Adjust the „LEVEL" control(s) to the marked (original) position again, disconnect the test
speaker and reconnect the original speaker(s).
9. Repeat for any other channel(s) you wish to fine tune.
4.3.5 LPF / HPF
If the LPF switch is pushed into the 'LPF' position, the input signal will pass the low pass
crossover. If the LPF switch is pushed into the 'FLAT' position, the signal will not pass the low
pass crossover.
If the HPF switch is pushed into the 'HPF' position, the input signal will pass the high pass
crossover. If the HPF switch is pushed into the 'FLAT' position, the signal will not pass the
high pass crossover.
When the input signal has been already filtered in an earlier stage (e.g. subwoofer output of
the head unit or another amplifier), this push button has to be in the 'FLAT' position.
4.3.6

Highpass filter

When a high pass filter is chosen, only the higher frequencies can pass
to the loudspeakers.
Push the HPF switch into the 'HPF' position to use this filter. The
crossover frequency is variable from 50Hz to 250Hz and can be
individually adjusted. Turn clockwise to set to a higher frequency, turn
counterclockwise to set to a lower frequency.
4.3.7

Lowpass filter

When a low pass filter is chosen, only the lower frequencies can pass to
the loudspeakers.
Push the LPF switch into the LPF position to use this filter. The
crossover frequency is variable from 50Hz to 250Hz and can be
individually adjusted. Turn clockwise to set to a higher frequency, turn
counterclockwise to set to a lower frequency.
