IMPORTANT NOTICE REGARDING BASS MANAGEMENT: It is important the signal
being sent to the subwoofer be a non-boosted or “at” signal. To be sure of this, check
the settings on your receiver or processor to make sure any “bass boost”, “super bass” or
“loudness” is set to O. In most cases a home theater receiver or processor will determine
the crossover frequency through bass management settings. In this conguration, connect
the receiver’s or processor’s subwoofer output to the subwoofer’s LFE Line Level Input.. Your
subwoofer will now reproduce the bass frequencies the way they were originally recorded.
Use the subwoofer level control and the individual bass management control within the
receiver or processor to adjust the subwoofers’ volume if necessary. Once set, the volume
controls should not need to be altered as the subwoofers’ volume will track with the master
volume control of your receiver or processor.
