9. The sub automatically calculates the
best equalization, based on the mea-
sured frequency response at your listen-
ing position. This will be saved, before
returning to the normal listening mode.
10. In normal listening, you can adjust the
overall effect of the saved EQ settings
with the Equalizer Authority control.
Normally you would turn it to 100% for
full equalization. You can turn it to 0%
to judge the effect of no equalization, or
vary it to suit your taste.
11. Repeat the Auto EQ procedure if you
change the location of the subwoofer, or
if you rearrange your furniture.
Manual EQ Mode
This mode allows you to manually
adjust the room equalization to suit your
taste. Some rooms may sound ß at or life-
less without a touch of color to the sound.
The subwoofer has four EQ bands,
each represented by two yellow LEDs.
Each band is Þ xed in frequency and
bandwidth, but each can be adjusted in
volume level using the Equalizer Author-
ity control during the Manual equalization
mode.
This is similar to
having sliders on
a 4-band graphic
equalizer. except the
settings for each band
are stored digitally.
The subwoofer saves the setting of the
Equalizer Authority control for each band,
so adjusting it for one band does not alter
the adjustment for the other bands.
First, you should follow the Automatic
EQ procedure, so the subwoofer will
adjust for the room effects. Then follow
this manual procedure if you think the
equalization might still need a tweak:
1. Set these controls:
• Volume to 0 dB.
• Crossover to "Bypass."
• Phase to "Normal."
• Equalizer Authority to "50%"
2. Turn on the subwoofer AC power switch.
3. Press and hold down the Start button
for several seconds, until the Þ rst pair of
yellow LEDs light up.
4. A low frequency test tone will sound to
help you adjust the lowest band.
5. Adjust the volume by turning the Equal-
izer Authority control (or press Start to
skip and move on to the next band).
You will have to sit back in your listening
position each time to listen for the effect,
or seek the help of a loved one or kind
friend to turn the control while you listen.
6. Press the Start button to move on to the
next band, and then adjust the Equalizer
Authority control as needed. When you
reach the last band, the next press will
bring up the Þ rst band again.
7. When all bands have been equalized to
your satisfaction, press and hold down
the Start button for several seconds
until all the yellow LEDS come on, and
the test tone turns off. The Equalizer
Authority settings will be saved for each
band. and the subwoofer will return to its
normal listening mode.
8. Use the Equalizer Authority to adjust the
effects level of your equalization.
