Basic Operations

Adjusting the Sound

You can adjust the sound of the woofer to suit the sound of your front speakers. Reinforcing the bass sound gives you a greater sense of atmosphere.

Note

If the sound distorts when you turn on the bass reinforcement from your amplifier (such as, DBFB, GROOVE, the graphic equalizer, etc.), turn off the bass reinforcement and adjust the sound.

Note

Selecting NORMAL or REVERSE with the PHASE button reverses the polarity and may provide better bass reproduction in certain listening environments (depending on the type of front speakers, the position of the woofer and the adjustment of the cut-off frequency). It may also change the expanse and tightness of the sound, and effect the feeling of the sound field. Select the setting that provides the sound you prefer when listening in your normal listening position.

To make the most of the low level converter function of Dolby digital,

 

turn the CUT OFF FREQ as high as possible when playing back the

 

Dolby digital (AC-3).

 

 

2

Adjust the volume level of the woofer.

Turn the LEVEL control so that you can hear the bass sound a little

 

more than before. Do not raise the bass excessively as this will result

 

in the loss of balance and depth. To increase the volume, turn the

 

control clockwise. To decrease the volume, turn the control

 

counterclockwise.

 

 

3

Play your favorite song and movie.

Male vocal tunes and voice containing bass sounds are most suitable

 

for adjustment. Turn the volume for front speakers to the same level

 

as usual. When playing a movie, raise the volume higher than the

 

level for music to produce a more powerful sound.

Select the phase polarity.

Press the PHASE button to select the phase polarity.

Repeat steps 1 to 4 to adjust for your preference.

Once you have adjusted the woofer to the settings you desire, use the

VOLUME control on the amplifier to adjust the volume of the woofer with that of the other speakers. You don’t need to adjust the woofer settings when you change the volume level of the amplifier.
