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.

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.

Setting the Speaker Configuration

Front L/R

The high pass filter attenuates low fre- quencies at 12dB per octave. The values given are for the -3dB point.

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 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.

Center

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