To Perform Automatic Calibration:
1. Put the Nº502 into Standby mode.
2. Connect the Mark Levinson microphone cables to the Nº502 rear
panel Microphone Input connectors. Ensure there is a good
connection between the microphone cables and the connectors.
We recommend labeling each microphone with the microphone
input number reflected on the Nº502 rear panel connector, to make
possible troubleshooting simpler.

confirms that the microphones are properly connected and
functioning.
calculates the average level of the microphones connected to the
Microphone Input connectors to ensure that the microphone
levels are consistent. This average-level calculation eliminates
errors due to different individual microphone levels by allowing
the Nº502 to compensate for individual microphone sensitivities.
7. Place the four microphones in the listening space as instructed on the
display. Both initial instructions and status information are displayed
as the test proceeds.
Proper microphone placement is essential to achieving optimum
calibration results. Pay particular attention to ensuring that the
microphones are properly placed.
During the Check Microphones test, position the microphones:
D as close together as possible.
D relatively centered between, and equidistant from, the front left
and front right speakers.
D in a clear line-of-sight path with all of the speakers.
D in a location unobstructed by furniture and other fixtures, where
echoes will not obscure calibration noise signals.
D at least 2 feet (0.61m) from all speakers and walls, but within 30
feet (9.14m) of all speakers.
