6. Calibration
You must calibrate the relative level of each channel to get a
proper surround sound presentation. For the most precise
calibration, you should use a sound pressure level (SPL)
meter. A loud pink noise tone will come from the selected
speaker when you press the associated button. Adjust each
channel's output level to 75dB using the VOLUME UP or
VOLUME DOWN buttons. The levels should be adjusted from
the same listening position used in STEP2.

7. Compression
This feature allows you to compress the dynamic range of the
sound which may be helpful for low volume listening late at
night. Turning this feature off will permit full dynamic range.
When turned on, louder passages are softened and softer
passages are increased to maximize intelligibility of speech.
Use the SELECT button to toggle between on and off.
8. Status Display
Press the SELECT button to toggle between STATUS DISPLAY
ON and OFF. When turned on, an OSD appears for 2 seconds
each time you press a button. This OSD appears only when
using the "main out" composite or S-Video outputs. The
selected INPUT<SURROUND MODE and VOLUME LEVEL will
be displayed.
9. DVD Audio Full Range
This setting applies only to the 7.1 "analog pass through" input.
Use the SELECT button to toggle between "yes" and "no".
When "yes" is selected, all signals present at the input will be
sent to the output and be affected ONLY by the VOLUME
control. When "no" is selected, the filters are defined by the
"SPEAKER SIZE" settings chosen in Step1. Channels set to
"large" will receive a full bandwidth signal while channels set
to "small" will have limited low frequency response (80Hz
filter). The analog filters will remove the low bass frequencies
from the signal and redirect it to the subwoofer.
