Boosts bass response.
Useful for listening at lower levels in larger rooms.
High-pass Mode
When using an external subwoofer, this setting allows you to finely
tune the frequency cut-off for frequencies sent to the LSX drivers.
The minimum high-pass setting is 50Hz and the maximum is
120Hz. Use in conjunction with the
Sub out low-pass
frequency
setting to fine tune the relationship between the
subwoofer and the LSX.
Sub out low-pass frequency
This is the frequency at which the signal is sent to the subwoofer
and not to the LSX drivers. Frequencies below the set point will
be sent to the subwoofer. The higher the set point the more bass
(in frequency) is sent to the subwoofer.
For best results when using this setting, set the crossover
control on the subwoofer to its highest position and
control the crossover output from the KEF Control App.
Sub gain
Allows you to control the subwoofer volume from the KEF
Control App.
For best results, turn the volume control on the
subwoofer past the highest position you would be likely to
use. This will allow you to control the volume of the
subwoofer from the KEF Control App.
Sub polarity
This setting adjusts for setups where the subwoofer output is not
in the same phase as the LSX output.
For example, in an extreme condition, a subwoofer may be set up
facing the LSX. This would cause the subwoofer to be 180° out-of-
phase with the LSX output which would diminish bass response
noticeably. For this condition, the polarity selected would be
-
.
There are several other factors that affect subwoofer
polarity. For best results, switch between the two settings
while playing the same audio output and let your ears
determine whether the polarity should be set to
+
or
-
.
Saving Your Custom Profiles
After you are satisfied with your adjustments, select the
Save
option. Multiple profiles can be saved for future reference.
Different programs and sources may be mixed and
mastered differently and will therefore sound different on
your speakers. You may want to save separate profiles for
louder music, television programs, or any of your other sources
and preferences.
