SET BALANCE
This step adjusts the output level of each channel so that they are properly matched. This must
be done to insure a correct presentation of multi-channel sound sources. The adjustment must
be as precise as possible, and is almost impossible to accomplish by ear. Therefore, we
recommend that you use a Sound Level Meter. This device insures that all loudspeaker levels are
precisely matched and set accurately. (The Radio Shack Analog Sound level meter is inexpensive
and suitable for this task.)
NOTE: If for any reason you are not sure that you can accomplish this calibration task
or have any doubts as to how it should be done, please contact Cary Audio's technical
support group BEFORE attempting this process (919-355-0010), or use Auto Setup.
Set the meter to Slow response, "C" weighting, and to the 70 dB sensitivity scale. Position the
meter at the approximate center of your listening position, at average ear height [approximately
40-46 inches (102-117cm)] with its microphone positioned vertically (pointing at the ceiling).
Don't aim the microphone at the speakers, as this will produce inaccurate results. To proceed
with the adjustments, you will access the Channel Calibration menu shown below. Set all
channels to 75 dB level.
NOTE: The following selected menus appear on the Cinema 11 Display.
