APP „SUB CONTROL 3.0"
3 LOW PASS FREQUENCY:
4 PHASE ANGLE:
The upper limit of the frequency range that the subwoofer is to reproduce is set
using the „LOW PASS FREQUENCY" parameter. Audio signals above this LOW
PASS FREQUENCY are progressively rolled off by the subwoofer, so that they
are no longer audible. The setting for this low pass frequency depends on the
respective loudspeaker configuration on the one hand, but also on its placement
and personal listening taste on the other.
The table below is provided as a rough guide for settings.
Loudspeaker configuration
Surround-sound system with LFE channel
HiFi stereo system with small loudspeakers
Satellite / subwoofer system (stereo)
HiFi stereo system with larger bookshelf loud-
speakers, smaller floorstanding loudspeakers
(like most ELAC loudspeakers)
Selecting the correct phase ensures that the bass signals reproduced by the
subwoofer blend seamlessly with those from the main loudspeakers.
If the subwoofer and main loudspeakers are operating in phase, this results in
homogeneous bass reproduction across the entire bass frequency range, with
no „holes" and no peaks that manifest themselves as a droning bass sound at
specific frequencies.
The correct setting for the phase adjustment must be determined by listening
tests. Play a piece of music that contains a wide range of different bass frequen-
cies. The phase is correctly set if no frequency stands out unpleasantly and all
frequencies are reproduced at a consistent volume.
