CALIBRATING OUTPUT LEVELS
Selecting the SPEAKER SETUP menu LEVELS CALIBRATION option
opens the LEVELS CALIBRATION menu, which can be used to
calibrate output levels for the audio output connectors. Calibration
ensures that output levels correspond to THX-reference levels
(75dB) for input sources such as DVDs.
Please note the following to ensure accurate output level
calibration:
• Use a Sound Pressure Level (SPL) meter to calibrate output
levels. An SPL meter is a device that measures the relative
loudness of the loudspeakers to ensure accurate calibration.
• Before output level calibration begins, eliminate extraneous
noises in the listening space, such as conversations, air
conditioners and sounds that filter in through open doors and
windows.

SETUP
• Before output level calibration begins, remove objects and
people that obstruct the line-of-sight path between the SPL
meter and the loudspeaker being measured.
• Output levels should be calibrated from the primary listening
position. Place the SPL meter at the approximate spot where
the listener
’ s head will be during listening.
INTERNAL NOISE TEST
Opens the INTERNAL NOISE message, which indicates that the
internal noise test produces loud calibration test signals. When
this message appears, press the Menu  arrow to open the
SPEAKER LEVEL ADJUST menu and conduct the internal noise test
or press the Menu  arrow to close the message without
conducting the internal noise test. When the SPEAKER LEVEL
ADJUST menu opens, the internal noise test automatically begins.
