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 ßat 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 Þxed 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 Þrst 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 Þrst 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.

Resetting the EQ

•Turn off the subwoofer using the AC power switch.

•Hold down the Start button and turn on the AC power switch.

•Keep the Start button held down for 10 seconds while the yellow LEDs ßash.

•When the LEDS go out, the EQ is reset to the ßat factory setting.
