The Speaker Configuration menu allows a wide range of choices in speaker
placement and room setups to provide optimal performance in almost any
room with virtually any speaker system. The menu allows you to set the
system for performance with center, sides, rear or subwoofer speakers. An
adjustable crossover is provided for systems with small center speakers,
and an 80, 100 or 125Hz, 24dB/octave rolloff crossover is available for the
subwoofer, as well as a complementary highpass filter for all other speak-
ers.
Press SELECT to access the selections for any highlighted menu item.
Front High Pass Filter
This 12dB per octave filter is useful for systems with small speakers, as it
removes low frequency content from the front left, center and right outputs.
Choices of 80, 100 and 125 Hz are available for the -3dB point. This filter
should be used if you are using THX-certified speakers. You may also want
to turn this control ON if you are using small satellite, or in-wall speakers
throughout the system.
Center
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
two main stereo speakers. This will automatically engage the Bass Split
feature which takes the low frequency content from the center, and distrib-
utes 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: 35, 60, 90, 115,
and 145Hz, or Bass Split OFF. Press DONE to return to the Speaker
Configuration menu.
