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). DIPOLE indicates a THX
speaker configuration, and causes the unit to mute the rear outputs when
any THX effect is used. 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.
