Refer to the following when adjusting. 1 Typical very small sized speakers: 5 – 7 cm dia. 2 Typical small sized speakers: 8 –15 cm dia. 3 Typical medium sized speakers: 16 –24 cm dia. 4 Typical large sized speakers: more than 25 cm dia. 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. 2 Adjust the volume level of the subwoofer. Turn the LEVEL control so that you can hear the bass sound a little more than before. To increase the volume, turn the control clockwise. To reduce 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. 4 Select the phase polarity. Use the PHASE selector to select the phase polarity. 5 Repeat steps 1 to 4 to adjust for your preference. Once you have adjusted the subwoofer to the settings you want, use the VOLUME control on the amplifier to adjust the volume of the subwoofer with that of the other speakers. You don’t need to adjust the subwoofer settings when you change the volume level of the amplifier. Notes • 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. • Do not turn the volume of the subwoofer to maximum. Doing so may weaken the bass sound. Moreover, extraneous noise may be heard. • Selecting NORMAL or REVERSE with the PHASE selector reverses the polarity and may provide better bass reproduction in certain listening environments (depending on the type of front speakers, the position of the subwoofer and the adjustment of the cut-off frequency). It may also change the expanse and tightness of 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.
