PERFORMING MANUAL OUTPUT LEVEL CALIBRATION

SETUP SPEAKERS MANUAL LEVELS 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.
