INTRODUCTION

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 woofers:
Each woofer uses an overhung voice coil and large excursion suspension to

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.
