System Configuration

Lexicon

Center

Bass Split rolls off frequencies at 12dB per octave. The values given are at the -3dB point of attenuation from the center speaker.

Systems that utilize a full-range center speaker should select LARGE to direct center information to the center output with a full frequency re- sponse. Select SMALL for installations where the center speaker is smaller than the left and right front speakers. This will automatically engage the Bass Split feature which takes the low frequency content from the center, and distributes it to the left and right front speakers, reducing the risk of damage to a small center speaker without loss of bass information. When SMALL is highlighted, press SELECT to display and adjust the crossover point for the low frequency redistribution. Available crossover points are: 40, 80 and 120Hz. Press DONE to return to the Speaker Configuration menu.

Sides

NOTE: When STANDARD SIDE and REAR speakers are selected, the output level of the side chan- nels is decreased slightly while the output level of the rear channels is increased slightly. This helps pre- vent the side speakers from over- powering the rear speakers.

Rears

NOTE: In software Version 4, when SIDE and REAR speakers are se- lected, the following changes are automatically made to THX 5.1 and DTS THX effects:

•SURROUND EX is set to ON

•"EX" is added to the effect name (for example, "THX 5.1 EX")

This menu sets the system for your particular side speaker configuration. Systems with side speakers should be designated as STANDARD (LARGE or SMALL) or DIPOLE (LARGE or SMALL). When STANDARD SMALL or DIPOLE SMALL is highlighted, press SELECT to display and adjust the highpass filter for the side outputs. Choices are:40, 80 or 120Hz. For any 5.1 channel inputs, selecting SMALL routes the low frequency information to the subwoofer output.

Selecting NONE mutes the side outputs and directs all surround informa- tion to the rear outputs.

The active selections are LARGE and SMALL. Systems that utilize full- range rear speakers should select LARGE to direct a full-range signal to them. SMALL should be selected when filtering is desired. (40, 80 and 120Hz are available as settings for the -3dB point). For any 5.1 channel inputs, selecting SMALL routes the low frequency information to the subwoofer output.

Selecting NONE mutes the rear outputs and directs all surround informa- tion to the side outputs.
