INTRODUCTION
Your new subwoofer has many features which help to deliver its great bass
performance and make it a remarkable value in home theater products.
* High efficiency amplifier:
Your home subwoofer utilizes a modern class A/B amplifier circuit to
produce high power with a minimum of heat.
* Versatile hook-up and operation:
Your new subwoofer has a variety of input and output connections that
make it easy to set-up and use in almost any stereo or home theatre
system.
* Low distortion woofer:
Each woofer uses an overhung voice coil and large excursion suspension
to produce higher sound pressure levels with lower distortion.
* Optimal enclosure:
Each enclosure is designed to match the parameters of its woofer
to maximize performance. Special low noise vents are used for less
distortion at the bottom of the frequency range.

SET-UP AND ADJUSTMENT
After you have selected an initial location for your subwoofer and have
connected it into your system, have a seat in your normal listening position
and have someone help you with the following adjustments:
A) If you are using the line level inputs and your main speakers are
receiving a full range signal, set the subwoofer crossover frequency control
to its full counterclockwise position of 60 Hz.
B) Set the polarity switch to the “normal” position and the level control to
the full counterclockwise position at “minimum”.
C) Turn off the loudness control and set the bass tone control on your main
amplifier to the flat position.
D) Use familiar program material that has substantial bass content and play
your main system at a moderate volume level.
E) Slowly rotate the subwoofer level control clockwise until a good balance
is achieved between the low frequency output of your subwoofer and the
mid bass and upper frequencies from your main speakers.
F) Change the polarity switch from “normal” to “reverse” to determine which
position results in the most overall bass output. Leave the switch in the
position that gives the highest output level.
G)Slowly rotate the subwoofer crossover frequency control clockwise to
attain the best blend between the level of the subwoofer and the main
speakers in the midbass crossover region. Advancing the control too far will
cause a “boominess” in the overall sound and will add an unnatural “chesty”
quality to male voices.
