Blinking audio REC LED's?

was running the OT as mixer an iPad and a laptop the other night,…all running fine - then late in evening I noticed the LED’s on A-B were blinking red, A then B then A etc,…haven’t seen this LED behaviour before > no audio problems -signal still coming through AB -
Any clues as to what caused this / is it a problem / bug?
cheers,

EDIT: did some manual research,…seems like I may have accidentally hit CUE + AUDI RECORD!? - routing the inputs directly to the CUE outs! -

  • the party was getting pretty loose at that stage,…ha ha

Are you sure it wasn’t your brain blinking and not the OT?

not sure,… the CUE+REC button combo worked it out :zonked:
