To receive the best quality audio we always suggest using the 'REC-OUT' ports on the back of any mixer that has them. This is due to getting a clean audio signal without the master affect the quality.
If you decide to use the 'MASTER-OUT' or 'BOOTH', please make sure you have it controlled. If either is peaking in the red zone you will get a distorted mix. This is something you do not want after a good set.
