SET UP CALIBRATION
For best results when setting up your system, assume your normal listening position and
have another person perform the following adjustments:
1. Set the Subwoofer Level to its zero position. Set the Subwoofer Roll-off
Frequency Control
to 50Hz. Set any loudness, bass/treble, and/or equalizer
controls on your preamplifier or integrated amp/receiver to their normal or mid-point
positions.
2. Play a familiar CD, record, or video soundtrack that has substantial bass content.
3. Gradually turn the Subwoofer Level control clockwise until you achieve a neutral
balance between the subwoofer's deep bass output and your main/satellite speakers.
4. Slowly turn the Subwoofer Roll-off Frequency Control clockwise to reach the
best mid bass blend with your main/satellite speakers.This will be the point at which
the bass retains solid impact and fullness. If the mid bass becomes "boomy" or ill
defined, you have gone too far and you should turn the control counter-clockwise to
the best balance point. If the sound is too thin (i.e., male vocals are not full sounding)
then turn the control clockwise to the best balance point.
NOTE: The Subwoofer Level Control is designed to control the balance between
your subwoofer and main/satellite speakers and should not be used as a substitute for
the bass or loudness controls on your amplifier or receiver.Adjust the subwoofer's level
for smoothest low frequency performance. If more bass is desired, advance the bass
and/or loudness controls on your main amplifier or receiver.
