Hey guys, looking for some expert opinion. I bought half a dozen pristine UPAs out of a drama theatre install. They don't know what happened to the M-1A processors. Now I've tested all the boxes biamping them at 1.6k like Meyer recommends, they sound good. What is the processor going to do for me, some time/phase alignment? I know there's protection circuitry. The processors don't appear easy to locate. Can a guy find a workaround with other hardware? Thanks.
