22 . www .velodyne.com Digital Drive User’s Manual About Room Placement. Room placement is the first step in equalizing your sub(s) to your room. Subwoofers operate a t extremely low frequencies, which are primarily omni - d irectional (that is, you can’t usually tell where they are coming from).
23 . www .velodyne.com Digital Drive User’s Manual T IP: Here’ s an easy way to find the optimal position for the subwoofer without moving it to multiple positions in the room. Star t by setting the subwoofer up in your listening position. N ow , move the microphone around the room and obser ve the response graphs for dif ferent room positions.
24 . www .velodyne.com Digital Drive User’s Manual A ND 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 S ELECT button, then the UP and DOWN arrow keys.

26 . www .velodyne.com Digital Drive User’s Manual N OTE: Some receivers/processors supply a signal that is already crossed over – i.e. just the bass frequencies. If this is the case, you will want to defeat the subwoofer’ s low pass crossover .
27 . www .velodyne.com Digital Drive User’s Manual N OTE: Y our 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. A nother big factor in smoothing this point in the cur ve is phase, discussed in step 17, below .
28 . www .velodyne.com Digital Drive User’s Manual N OTE: The following step shows using the graphic equalizer (using fixed frequencies and Q) to equalize the room. 18. Next, return to the EQ setup screen and adjust the graphical EQs to eliminate peaks and valleys from the room response.
29 . www .velodyne.com Digital Drive User’s Manual 1 9. Continue this process until the “SYSTEM RESPONSE” graph shows a +/– 3 dB response across the bass frequencies (that is, up to about 120Hz.). Note that this does not n ecessarily mean a “ruler flat” response; +/- 3dB is typical for an optimized response cur ve.
30 . www .velodyne.com Digital Drive User’s Manual 2 0. T o have the unit EQ itself, select the auto EQ option, as shown: When this mode is selected, the unit automatically resets all EQs to their original frequencies, and Q settings (but retains any level changes you may have made).
31 . www .velodyne.com Digital Drive User’s Manual N OTE: 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 24. 21. T o use the parametric EQ feature, position the cursor over the EQ and press the SELECT button.
32 . www .velodyne.com Digital Drive User’s Manual 2 2. T o 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 U P and DOWN arrow keys to adjust the level of the EQ as before.
