I have a Universal audio preamp, a neuman mic and a 828 mk3 audio unit. When I plug the mic through the preamp then out in the 828, then I have signal in the preamp and the 828. But nothing in logic, what is the process in logic to get yhe signal on rec ? thanks
So, both the Audio Input and Output in Logic's Preferences/Audio is set to the MOTU.
The Mic works when only the MOTU is being used.
When using the Preamp, you will not need Phantom power engaged on the MOTU, phantom power should be off on the MOTU unit and only engaged on the Universal preamp.
Other than that I think this is probably a Cuemix setup problem, I use RME hardware so I can't tell you how to setup the line inputs.
On Logic's Audio Channel Input selection, how many Input numbers do you show?
