7.Use the DD remote control to MUTE the subwoofer
9.Now use the DD remote control to unmute the subwoofer, then use the volume up and down keys to match the level of the subwoofer to your full range speakers. That is, the “SYSTEM RESPONSE” graph should be relatively flat although at this point there will be peaks and valleys that will be addressed next. The screen should now look something like this

AND REMEMBER Use the UP, DOWN, RIGHT and LEFT directional arrow buttons that surround SELECT to move through the fields of the setup screen, and change settings by using the SELECT button, then the UP and DOWN arrow keys. Or, you can skip the SELECT button and change values using the SET +/- buttons
TIP To see immediate feedback on the effects of your changes to the “SYSTEM RESPONSE” graph, press the TEST button. The following screen appears

NOTE Your goal in setting the low pass crossover is to make the crossover point the point at which the subwoofer meets the main speakers in terms of frequency as smooth as possible. Another big factor in smoothing this point in the curve is phase, discussed in step 17, below
NOTE The following step shows using the graphic equalizer using fixed frequencies and Q to equalize the room
An “equalized” room is shown below

20. To have the unit EQ itself, select the auto EQ option, as shown
NOTE The following steps use the parametric equalizer to achieve room equalization. If you do not wish to use the parametric EQ feature, skip to step
22.To manipulate a parametric EQ, you can now use the LEFT and RIGHT arrow keys to move the frequency up and down, and the SET + and SET - keys to change the Q value. Use the UP and DOWN arrow keys to adjust the level of the EQ as before. A selected EQ that has been moved, with its level raised and Q adjusted is shown below
24.Once the room has been equalized, you may want to return to the Settings Setup screen by positioning the cursor over the NEXT field on the EQ setup screen and pressing SELECT
Crossover, subsonic filter, phase and polarity settings. Normally these will not change from preset to preset. However, it may be that you are using different satellites for different listening modes and wish to set these settings individually for a specific preset. Note that the “setup” values cascade to the individual values for the presets, but you can change all the individual values if desired
Contour frequency and level. These act as an “extra” EQ that can be used to manipulate the frequency contour of your subwoofer when this particular preset is invoked. For example, notice that preset one raises the level by 3 dB at 35Hz - this is to accommodate action/adventure movie content
24.As a final thought on matching your Digital Drive subwoofer to your room, don’t forget the “objective listening” test. That is, make sure the unit sounds good to you! Often, you may want to add a bit more bass than what would normally be considered “flat” even after you remove the major peaks and valleys to achieve a flat frequency response. This is quite normal because human hearing “rolls off” rapidly below 100Hz, causing the bass not to sound as loud. This is the basis for the “loudness contour” switch included on many receivers and preamps. In order for the bass to sound flat, especially at lower levels, you may need to increase the subwoofer volume in relation to the satellite speakers. An increase of about 5-8dB is usually adequate. There are two methods to accomplish this
