CALIBRATING OUTPUT LEVELS

SETUP SPEAKERS LEVELS CALIBRATION

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 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:

•It is recommended to 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 accurate output level calibration. SPL meters are available at Radio Shack (catalog number 33-2050).

•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.

•Before output level calibration begins, remove objects (as well as 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

SETUP SPEAKERS LEVELS CALIBRATION 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.
