Can you beg/borrow/steal another phantom powered mic and spare XLR cable? This'll let you do some effective testing. If the static is still there with a different mic and cable, you probably have a faulty mixer. If the static is gone in the new setup then swap back to your MXL and the new cable. If the static is back, then it's your mic. If it's still gone, you probably have a faulty cable which you can confirm by using your cable with the borrowed mic.
Since all your gear is new, there's a reasonable chance that something arrive with a problem and needs replacing under warranty. Trouble is, you need to do the sort of detective work noted above to chase the problem down.
