8.4.6 Auto Volume does not calibrate
Auto Volume calibration may fail if the process cannot obtain an
adequate source level. This may be due to:
• Speakers are tapped too high
• Maximum output gain is less than -20 dB
• Source is not operating
• Source level is too low
Calibration could also fail if the calculated loop gain is not within
required limits. This may be due to:
• Broken microphone cable
• Speakers are not connected
• Sensing microphone is not connected, or is connected to the
wrong zone
