RTA MIC Input
This balanced XLR input is used for the connection of an RTA microphone. This allows the
PA+ to measure pink noise that is sent through the speakers. The Auto-EQ Wizard can then
optimize the EQ settings for any room. You can also use the full-time RTA feature to monitor
levels and make adjustments yourself.

select parameters and edit parameter values.
