AUTOMATIC CHANNEL CYCLING FOR CINEMA 2 HOME THX AUDIO SURROUND
LEVEL CALIBRATION
The Automatic channel cycling mode of Home THX Audio surround level calibration is not
recommended since there may not be adequate time to get valid readings from the Sound
Level Meter.
WHEN HOME THX AUDIO CINEMA 2 SURROUND CALIBRATION IS COMPLETED,
A LASER VIDEO DISC WILL PLAYBACK ITS MOVIE SOUNDTRACK IN YOUR MclNTOSH
HOME THESTER SYSTEM AT THE SAME VOLUME LEVELS HEARD BY THE MOVIE
PRODUCER WHO CREATED THE ORIGINAL SOUNDTRACK. THIS WILL ALSO BE THE
SAME LEVEL THAT YOU WILL HEAR IN A THX CALIBRATED MOVIE THEATER. VIDEO
TAPE AUDIO LEVELS MAY VARY FROM THOSE OF A LASER VIDEO DISC.

SURROUND LEVEL ADJUSTMENTS DURING LISTENING

During the actual listening and viewing process of a movie, you may wish to adjust the
LEFT and RIGHT SURROUND sounds to volume levels different from this set during the
calibration process. Do this by pressing the UP ( ) or DOWN ( ) SURROUND pushbutton
on the MX130 Hand Held Remote Controller until you are satisfied with the results. These
changes will remain as long as the MX130 continues to operate.
When the MX130 is turned off, the surround sound volume level changes you made
during listening are canceled and all the original calibrated levels are restored.
If you wish to permanently recalibrate to different surround trim levels, turn off the MX 130.
This will cancel the manual level changes and restore the volume levels set in memory dur-
ing the most recent calibration process. Then turn the Control Center back on and repeat
the calibration process to put your new preferred surround sound levels in memory.
Do not attempt to recalibrate surround levels after manual adjustment without first
turning the MX130 OFF and then ON, to restore the calibration memory to the original
settings.
If you do not have a sound level meter available, you can calibrate all six channel
levels by ear. You will find the results enjoyable, however, you will not necessarily be
listening at the same exciting volume level as intended by the movie producer.
