RBH Sound PC-10 SUBWOOFER - Manual (Page 4)

Placing the subwoofer away from walls will provide the least reinforcement,
making the bass sound subjectively thinner than if the woofer were closer to
a wall. Good results can usually be obtained by placing a subwoofer along a
wall 1-3 feet from a corner. Experiment with placement of the subwoofer and
the sub-amplifier controls to achieve the proper bass balance.
It is important the signal being sent to the subwoofer be a non-boosted
or “flat” signal. To be sure of this, check the settings on your receiver or
processor to determine any “bass boost”, “super bass” or “loudness” is set
to Off. In most cases for home theater setting a receiver or processor will
determine the crossover frequency through bass management settings. In this
configuration connect the receiver or processor to the LFE Line Level Input.
Your subwoofer can 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 coincide with the master volume control
of your receiver or processor.
