Thanks very much for your helpful article about PA system recommendations. I hope Bose & Sennheiser are kind to you! I upgraded to both recommended items & during testing at home & at a venue it worked perfectly, but once the ceremony started there was some audio issues; couple of those high pitches squeaks and I think a bit of cutting out. It wasn’t a disaster but also wasn’t great, and I’d like my audio to be as good as poss so just trying to figure it out before the next ceremony.
