For a simple but very acceptable live recording system buy this:
Of course, make sure the Apple connection is the same as the one used by your air pad. There are other models available that will fit whatever you need.
The simple app that comes with it gives you the ability to change the mike pattern, eq and gain. You can record a video or just audio.
The quality is very, very good and it’s easy as pie.
Further mastering with Logic Pro X is the next step.
Is this wireless microphone system a fair rival to Shure?
