In the Ui24R SETTINGS / LOCAL page, the default settings for CPA, Hide CPA Serial Number and Hide CPA Message are “ON”.
These settings can be changed as follows if desired:
If you change “CPA” to OFF, then no IOSYS channel messages will be displayed.
If you change “Hide CPA Serial Number”, then the product serial number will be displayed in between the model
number and channel ID number at the bottom of the input channel strip.
If you change “Hide CPA Warning Message”, then an “IOSYS” message will flash very briefly across the mixing
window and then disappear.
