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.

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.

Bass Split rolls off frequencies at 12dB

per octave. The values given are at the

-3dB point of attenuation from the center

speaker.

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.

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")
