| pan law should only affect what's happening in the centre of a stereo track. -3dB means the centre signal drops by 3dB (same as when you pop the pan button in on a Neve) - in the analogue world, the best compromise - if it was totally linear, you'd get an increase in level in the centre, which would mean things get noticeably quieter when you panned out to one side, due to coherent signals summing in the centre - I've probably not explained that very well!).
Anyway, what's the through signal like? ie if you send a tone at 0VU into your interface, pan the mono track to one side, output it again into the desk, you should have -18dBFs in Logic, then 0VU at the console again. If you don't - something's not lined up right!
Which doesn't actually explain why the stereo output should be showing clipping though, unless as I mentioned your audio track fader has been turned up at some point. |
