How to use function
12 and 13
The subsonic filter cuts unwanted frequencies in
the deepest bass range. An example of unwanted
sound is "rumble" from a turntable or wind noise
from a microphone.
The reason to cut these unwanted frequencies:
- To decrease the noise level in the listening room.
- Subsonic noise causes unnecessary
high power from the amplifier.
- To decrease non-linear distortions
in the amplifier and the loudspeaker.
- Increase the power "headroom"
- Some rooms amplify the lower frequencies
so the bass frequencies get "uncontrolled".
Select frequency:
A
typical value is 20Hz, but use whatever is most
suitable.
Select slope:
A normal value is 24dB but try what suits you best.
With a perfect adjusted subsonic filter you achieve
the benefits:
- Higher useful power
(the subwoofer can handle higher sound levels).
- More control and a better sounding bass
- Decreased noise level in the listening room.
The functions 14, 15, 16 and 17 are dependant
on
each other and should therefore be used in a
certain order.
Function 14
HIGH-CUT FILTER / Frequency
High-cut filters cut the upper frequencies.
Adjustable from 40-250Hz.
Reason to use high-cut filter:
-To avoid frequency overlapping
with the main system
-To create an optimal acoustical cross-over
to the front system and/or home cinema system.
One step = 1 Hz
Function 15
HIGH-CUT FILTER / Slope
Select the slope on the high-cut filter.
Select 12dB or 24dB.
