Calibrating Audio Inputs
You can calibrate analog and MPX (composite) audio inputs using the remote AUI (see Calibrating
Audio - Using the AUI ) or using the local front panel display (see Calibrating Audio - Using the Front
Panel on page 2-97 ).
Calibrating Audio - Using the AUI
To view the AUI’s
Audio Input Calibration
page (see Figure 2.84 ), select
Audio Input Calibration
from the
System Settings
page. 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
Set
to save the changes. Click
X
in the upper, right corner to close this
page and return to the home page.

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 the audio input, ensure you have a
reliable and correctly calibrated audio source.
