Setting the Speaker
Configuration
The high pass filter attenuates low fre-
quencies at 12dB per octave. The values
given are for the -3dB point.
Select LARGE for full-range front speakers to deliver full frequency re-
sponse to the front outputs. Selecting SMALL activates a 12dB per octave
highpass filter and automatically routes low frequency information to the
subwoofer output. Choices of 80, 100 and 120 Hz are available for the -3dB
point. The 80Hz 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. Consult your dealer to determine their low
frequency capability.
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 adjustable lowpass filter is available for the subwoofer, as well as a
complementary highpass filter for all other speakers.
Press SELECT to access the selections for any highlighted menu item.
Front L/R
Bass Split rolls off frequencies at 12dB
per octave. The values given are at the -
3dB point of attenuation from the center
speaker.
CenterSystems 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
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: 80, 100, and
120Hz. Press DONE to return to the Speaker Configuration menu.
