DB1 presets enable setups appropriate for different types of program material or listening situations to be stored and easily recalled. We recommend that you take the time to setup one or more presets.

Selecting Presets from the Audio Menu will display the Presets menu illustrated above.

The three menu items provide the following functions:

Load

Loads one of the five presets for editing.

Edit

Enables the parameters shown in the following columns to be changed.

As you make adjustments, the outline around the selected menu item will change from blue to red to indicate that the changes have not been saved and will be discarded if you exit the Preset menu using the button.

Save

Saves the edited preset parameters to a specified location, overwriting the preset data previously stored. Saving causes the menu item outline to revert to blue.

Last Preset

This non-selectable label Indicates the number of the last Preset accessed for either a Load or a Save operation.

Edit Menu

Input: Enables the preset to specify either the mono or stereo DB1 input. The default is mono.

Level: Enables the preset to specify a DB1 volume level different from that set to balance the inputs. The default is 0dB.

Low-Pass:Enables the preset to specify that the DB1 low-pass filter is either In or Out of circuit. A preset configured for use with home theatre program material via DB1 connection to an AV processor LFE output should not have a low-pass filter engaged. The default is Out.

Edit Menu cont'd

Sys(tem) EQ: Enables the preset to specify either Impact or Flat equalisation. The default is Flat.

User EQ: Enables the preset to specify custom equalisation parameters defined by adjustment of the subsequent graphic equaliser menu. The default is all bands set to 0dB.

To adjust the graphic equaliser, use the and buttons to select a frequency and the and buttons to adjust the level of the selected frequency. Adjusting the graphic equaliser can help overcome room acoustic problems that result in unbalanced or inconsistent subwoofer performance. Aim for a relatively gentle use of graphic equalisation rather than extreme differences between adjacent frequencies.
