MAKING & SAVING PRESET CHANGES

The simplest customization of parameters you can do is to make and save changes to the presets.

You can modify the preset parameters either in the Preset Parameter Settings area on the Frequency Response and Parameters screen or on the Preset screen. The Preset screen has the advantage that you can see settings for all the presets at one time and also modify the night mode and power on settings. The Frequency Response and Parameters screen has the advantage that you don’t have to open the Preset screen.

See the Digital DrivePLUS User’s Manual for a detailed explanation of the preset parameter settings that you can modify.

To modify the presets using the Preset screen:

1)On the Frequency Response and Parameters screen, click Next (upper right hand corner).

•Some values are changed with pull-down menus, like the slopes, whereas others increment with up/down buttons.

•The parameter input fields can also be selected with the mouse and the value typed into them.

2)Click Previous to return to the Frequency Response and Parameters screen.

3)Click Save to DD+ to save the preset setting changes to the subwoofer’s memory.

4)Click Save to File to save the preset changes to a file on your computer. Velodyne recommends this practice as a way to “back up your work” and to be able to retrieve subwoofer settings without having the subwoofer connected to your computer. You can also save the settings using the File > Save menu option. Previously saved profile files can be retrieved using the File > Open menu option.

To modify the presets using the Frequency Response and Parameters screen:

1)In the Preset Parameter Settings area use the Preset pull down menu to select which preset to modify.

2)Use the pull down menus to change the preset parameter settings.

3)Click Save to DD+ to save the preset setting changes to the subwoofer’s memory.

4)Click Save to File to save the preset changes to a file on your computer.

RUNNING SELF-EQ OPTIMIZATION– YOUR FIRST EQ

The easiest EQ optimization to perform is the Self-EQ. With Self-EQ the subwoofer generates its own sweep tone. To perform Self-EQ optimization:

1)Remove the microphone, mic cable and stand from the accessory kit. Carefully snap the microphone into the stand and attach the larger end of the cable to it. See the Digital DrivePLUS User’s Manual for more information.

2)Place the microphone at the main listening position.

3)Attach the small end of the mic cable to the jack on the left side of the subwoofer front control panel.

4)Make sure the subwoofer is on and your audio system is off.
