I have worked at the same venue for many years and have noticed more frequent problems recently with hum and buzz
with some bands' equipment while most are perfectly fine. I suspect changes in the grounding such as corroded
ground rod connectors or dryness in the soil they are in. The boss is investigating.

I always try to run all PA and band equipment from the same circuit if capacity is sufficient. The previously
mentioned 750 foot run may be a problem though with probable significant voltage drop.

Cheers
Roger
