Audio Input Calibration
NOTE
: Audio inputs are factory set using a high accuracy source and do not typically require user
adjustment. Changes to factory calibrations could cause low or excessive modulation and non-
compliance to strict regulatory limits. If you need to re-calibrate an audio input, make sure you have a
reliable calibrated audio source.
The
Audio Input Calibration
page (see Figure 3.2.94 ) allows the user to calibrate analog and MPX
(composite) audio inputs. The peak meter value of each calibrated audio input (analog left, analog
right, MPX or MPX SCA, Int. SCA1 or Int. SCA2) that is applied will be displayed. Enter a valid
calibration value and click
Apply
to save the changes. Press
X
in the upper, right corner to close this
page and return to the home page.
