Low pass
The Low pass filter is the filter that removes all of the high frequencies
from the signal before it reaches the amplifier. When this filter is set
correctly, the subwoofer will blend in with the other speakers in your
system, and the entire system will sound naturally balanced.
The menu structure is as follows:
Slope
Frequency
See "Acoustic set-up procedure" for more details on setting the Low Pass
filter.
Filter 1 & 2
The menu structure is as follows:
Off
Notch
Frequency
Depth
Width
Boost
Frequency
Height
Each of these filters can be selected as a Notch or a Boost filter.
Notch/Boost filter - The response of a speaker in any room may have
peaks or dips that are created by acoustic reflections. The dimensions of
the room and the acoustic properties of the surfaces within the room
determine the location and size of the peaks. The notch/boost filters can
be used to cancel out these peaks to a large extent.
See "Acoustic set-up procedure" for more details on setting up the notch
filter.
