Setting Subwoofer Controls - Paradigm Reference Signature Serie Manuel D'utilisation

FINE TUNING
Once you have your speakers positioned in the room and have set speaker
distances and speaker level calibration with your Processor or A/V Receiver
(if applicable), it's time for a little fine tuning.
When fine tuning your subwoofer to best integrate with the rest of your system
use music and video soundtracks that you know well. They should contain
selections with extended bass that is continuous and repetitive.
Assess subwoofer bass output for best blend with your main speakers.
It should not be overbearing or draw attention to itself, nor should it be
thin and difficult to hear. It should add 'weight' and 'punch' to the overall
sound and keep pace with your main speakers.
If you are using a receiver, preamplifier or preamp/processor with tone
controls, set them to flat (i.e. '0') and switch loudness controls off.
Some subwoofer locations may result in bass frequency cancellations. If
bass sounds dislocated or weak, adjust the phase according to the Phase
Alignment Control instructions that follow below.

SETTING SUBWOOFER CONTROLS

1. Turn the Subwoofer Level control completely counter-clockwise to
its minimum.
2. Turn the Subwoofer Cut-off Frequency control to its highest
frequency (i.e.150 Hz).
3. Turn the Phase Alignment control to 0° completely counter-clockwise.

4. Listen to a bass music or video selection while seated in your primary
listening area and have an assistant turn up the Subwoofer Level
control until the subwoofer can be clearly heard.
5. Have an assistant slowly rotate the Phase Alignment control until you
hear the most bass. Your subwoofer and front speakers are now in phase. Do
not change phase alignment again unless you move subwoofer or front
speakers to a different location in your room.
6. Again, turn the Subwoofer Level control completely counter-clockwise
to its minimum.
7. Turn the Subwoofer Cut-off Frequency control to its lowest frequency
(i.e. 50 Hz).
8. Slowly rotate the Subwoofer Level control until you match the
subwoofer's volume with the volume of your front speakers. Bass should
be clearly audible, but not intrusive.
NOTE: If using an A/V receiver or processor to control crossover
setting, skip the next step and set the subwoofer cut-off frequency
control to 'Bypass'.
9. Slowly rotate the Subwoofer Cut-off Frequency control until you
hear the best subwoofer/front speaker blend. If the sound is too thin
you have not set the frequency high enough; if the sound becomes
boomy you have set the frequency too high. Adjust until you find the
most natural bass balance.
