PERFORMING MANUAL OUTPUT LEVEL CALIBRATION
Selecting the MANUAL SPEAKER SETUP menu LEVELS CALIBRATION option displays the LEVELS CALIBRATION menu to manually calibrate
output levels.
Note the following:
• You should use a Sound Pressure Level (SPL) meter to manually
calibrate output levels. An SPL meter is a device that measures
the relative loudness of the speakers to ensure accurate output
level calibration. SPL meters are available at Radio Shack.
• Output levels should be calibrated from the primary listening
position, placing the SPL meter at the approximate location
where the listener’s head will be during listening.
• Output levels for speakers that are not included in the speaker
setup cannot be adjusted during the internal noise test. These
output levels can be adjusted during the external noise test,
but there is no need to do so.
