The Lost Art of AV: 70v Distributed Sound

[@andrewh1306]

When I was younger I worked a lot of on 70V systems in stadium and auditorium settings (1980s) and it was a challenge to get any audio quality that didn't sound like a clock radio speaker. We also had major problems when one speaker was ripped off by a drunk guest or when cable runs came close to any other A/C wiring. Any tips on sound quality with these systems?
