CALIBRATING OUTPUT LEVELS
Selecting the SPEAKER SETUP menu LEVELS CALIBRATION option
opens the LEVELS CALIBRATION menu shown above, which can be
used to calibrate output levels for the Main Zone speaker or audio
output connectors. Calibration ensures that output levels corre-
spond to THX reference levels (75dB) for input sources such as
DVDs.
Please note the following to ensure accurate output level
calibration:
• It is recommended that you use a Sound Pressure Level (SPL)
meter to calibrate output levels. An SPL meter is a device that
measures the relative loudness of the speakers to ensure accu-
rate output level calibration. SPL meters are available at Radio
Shack.
• 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.
LEVELS CALIBRATION SPEAKERS SETUP
• Before output level calibration begins, remove objects
(in addition to people) that obstruct the line-of-sight path
between the SPL meter and the speaker being measured.
• Output levels should be calibrated from the primary listening
position, placing the SPL meter at the approximate spot where
the listener’s head will be during listening.
INTERNAL NOISE TEST
Opens the INTERNAL NOISE message shown above, 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 shown above and con-
duct 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.
