on the cables making proper contact? Is the AC plug connected to a "live" receptacle? Ha
the power button been pressed to the "on" position? (Note: A green indicator on the fron
panel will light when the power is on.) Once you have confirmed that the subwoofer
active, proceed by playing a CD, record or cassette. Use a selection that has ample bas

blend across the entire musical range. Many users have a tendency to set the subwoofe
volume too loud, adhering to the belief that a subwoofer is there to produce lots of bas
This is not entirely true. A subwoofer is there to enhance bass, extending the response o
the entire system so the bass can be felt as well as heard. However, overall balance mu
be maintained or the music will not sound natural. An experienced listener will set th

at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduc
some low-frequency sounds, set this control to a lower frequency setting, betwee
50Hz – 100Hz. This will concentrate the subwoofer' s efforts on the ultradeep bass sound
required by today' s films and music. If you are using smaller bookshelf speakers that d
not extend to the lower bass frequencies, set the low-pass crossover control to a highe
setting, between 120Hz – 150Hz.

Proper phase adjustment depends on several variables such as room size, subwoofe
placement and listener position. Adjust the phase switch to maximize bass output at th
listening position.
The EQ switch, located on the front panel, optimizes the subwoofer's performance fo
both movie and music listening. When in the "Video" position, a special EQ circuit
activated, enhancing low frequencies by approximately 3dB at 32Hz and delivering th
full impact and excitement of today' s movie soundtracks. When in the "Audio" position
the subwoofer provides the accurate and linear frequency response that is ideal when
natural tonal balance is desired for music listening.
Remember: every system, room and listener is different. There are not necessarily any righ
or wrong settings; any setting you choose will result in excellent performance. Should yo
decide to fine-tune your system for optimum performance, be patient and trust your ear
