So I'm trying to calibrate my CentralStation Plus. I've shipped a -18 dBFS signal out to the unit, held the calibration button for two seconds, watched the meters reset to 0, then increased the gain to 0 and gotten a clip light.
Then I sent a -17.9 dBFS signal out and repeated the process
The blue calibration button is still lit. Is this normal? Does it indicate it has been calibrated, or does it indicate the calibration hasn't been completed?
