Calibrating the
loudspeakers
T
he 541 Surround Controller includes a built-in calibration procedure to
help you to set up your installation to give the best possible sound with
any particular combination of associated equipment.
This calibration procedure uses a test signal so you can adjust each
loudspeaker to the same level.
You should work through the calibration procedure the first time you set
up your surround sound system, and whenever you want to check the
calibration, such as after changing the layout of your room.
