Operation Mode: Highpass FRONT & REAR
iPaul 4.300
This mode is used principally for kickbass operation of a front system or as subsonic filter for the bass load throw-
off of a front system. The maximum load of the kickbass loudspeakers can be substantially increased in this mode.
The high-pass, with 60-70 Hz and 12 dB slope per octave, removes frequencies below 60-70 Hz, which are
superfluous and harmful to the kickbass loudspeaker, thereby significantly improving the performance and lifespan
of the speaker. The kickbass performance of the loudspeaker is in no way reduced, but rather, the capabilities are
improved. Additionally the loudspeaker thermal and mechanical capabilities are strengthened.
•
Switch „X-OVER“ (14) should be adjusted to setting „HPF“ and the cut off frequency should be set by means
of the potentiometer „HPF“ (18) to between 15 Hz –5 kHz on the FRONT channels.
•
Switch „X-OVER“ (12) should be adjusted to setting „HPF“ and the cut off frequency should be set by means
of the potentiometer „HPF“ (22) to between 15 Hz – 500 Hz on the REAR channels.
In this setting, as described above, all frequencies below 60-70 Hz are removed with large slope from the
loudspeaker and therefore cannot be reproduced. Only the frequencies from 60-70 Hz to 35 kHz are fully available.
Therefore, in this mode a separate amplified subwoofer, which reproduces all frequencies below 60-70 Hz is
absolutely necessary.
