Setting the phase
(Phase)
With the phase settings you can adjust
the phase relationship between the
subwoofer and main speakers. If either
subwoofer or main speaker are slightly
out of phase in relation to the other, it
can result in decreased bass output in
the frequency response area where the
overlap each other.
The phase relationship between
subwoofer and satellite speakers is
very dependent on relative distance,
construction and working principles of
the main speakers. The gure above
shows a case whereby phase of the
subwoofer and main speakers are
incorrect in the critical overlap area, thus
signicantly reducing acoustic output in
the listening room in that area.
To nd the correct phase setting:
1. Play a bass-rich track which also
covers the overlap area.
2. Toggle the Phase switch between
0° and 180°. Choose the setting for
which you experience the most bass.
Setting the satellite cut-off
frequency (Highpass)
Depending on the bass capabilities of
the speakers, the frequency range of
subwoofer and speakers can overlap
between 50Hz and 150Hz. A bump or a
gap in the frequency response and thus
a lower sound quality will be experienced
if the system is not matched properly.
In addition, small speakers and low
powered ampliers will particularly be
affected by the low frequency signals,
which again has a negative effect on the
sound quality. Therefore it makes sense
to limit the bass range of the connected
speakers (called “satellites” in this case)
by a highpass lter. The 9S provides
three settings to achieve this:
• Flat = no limiation
• 60Hz = frequencies below 60Hz are
cut off.
• 80Hz = frequencies below 80Hz are
cut off.
To set the cut-off frequency
Switch Highpass control to needed
position.
Note
You can not set the phase if the
subwoofer is in slave mode. In
this case the phase in controlled
by the setting of the master
subwoofer.
