The Shure SM7B are all dynamic mics. They don't need Phantom power. However, the mics are connected to the Clouldlifter Mic Activator mounted under the table, which needs Phantom power to operate. The Cloudlifter Mic Activator is connected to Audient iD44, which provides phantom power. Phantom power doesn't go through Cloudlifter so it is safe for the mics. Therefore, all the Phantom power switches on the Audient iD44 audio interface must be turned on.
To record multiple mics simultaneously, create new tracks, choosing the inputs for each mic you are using. Then go to “Track” > “Configure Track Header...” and click the checkbox for “Record Enable”. This shows a little red record button on each track now. Click on that record button for each track you want to record simultaneously, and it will start blinking. Now when you begin recording, they will all record.
If this does not fix the problem, please ask one ofthe staff or student workers for assistance.
