This concludes the SOS section.
The effect of the optimized filter on your system will depend in large part on the system source
material and may not be easily discernable. In order to better detect the differences between filtered
and non-filtered operation, a test tone generator has been designed into the system. The generator
provides a repeating 20 to 80 hertz frequency sweep and is engaged by setting the unit TEST switch.
Setting the switches on the ULW-10 to OPERATE – FILTER – TEST provides test tones with the filter
engaged. Setting the switches on the ULW-10 to OPERATE – BYPASS – TEST provides test tones with
the filter removed.
To return to normal SOS operation, set the switches on the ULW-10 to OPERATE – FILTER – NORMAL.
The room resonance filter settings will remain stored within the unit and you will not need to repeat
the calibration procedure.
In the situation where two ULW-10s have been used, set the switches on ULW-10 B to OPERATE –
BYPASS – NORMAL and the switches on ULW-10 A to OPERATE – BYPASS – TEST to provide test
tones with the filters removed. Set the switches on ULW-10 B to OPERATE – FILTER – NORMAL and
the switches on ULW-10 A to OPERATE – FILTER – TEST to provide test tones with the filter engaged.
To return to normal SOS operation, set the switches on both ULW-10s to
OPERATE – FILTER – NORMAL. The room resonance filter settings will remain stored within the unit
and you will not need to repeat the calibration procedure.

Test Tones
The optimum location for the microphone during the calibration procedure is in the room where
you are most likely to sit when using the system. This is where you will want to place or hold the
microphone during the measurements. The microphone should be oriented such that it is at your
seated ear level with the cartridge (large end) pointing up toward the ceiling.
Room response nulls can occur at any frequency within the listening environment. These nulls are
caused by the destructive wave interference of the sounds within the listening environment and
are a factor of the size, shape, and configuration of the environment. Response nulls occur in
fixed locations within the environment and may affect the calibration process of the Subwoofer
Optimizer System. If after running the calibration process and listening to the system performance,
the system does not appear to have a noticeably smoother response, repeat the process with the
microphone relocated to a different location. Usually you will only need to move the microphone a
few inches horizontally to correct the problem. Do not move the microphone more than 12 inches
away (in any direction) from your preferred location.
