LEVELS CALIBRATION MANUAL SPEAKERS SETUP
Note the following:
• It is recommended to 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 (catalog no. 33-2050).
• Output levels should be calibrated from the primary listening
position, placing the SPL meter at the approximate location of
the listener’s head during listening.

output levels can be adjusted during the external noise test,
but there is no need to do so.
