Disclaimer: Yes, I know this is old, dinosaur gear, and yes, I'll join the 21st century at some point. Most of my gigs are PA provided but for some I have an old Yamaha two-channel powered mixer and passive mains and monitors. In a moderate volume setting, it's fine, actually sounds really really good, but last night, NYE gig, (too freaking) loud rock band, we had some intermittent popping or clicking coming from the monitors. No idea if it was also the mains, as we were running our own sound (and no one complained, although that may be here nor there...). Since the band was (tool) loud, they of course kept telling me "turn up the monitors." I tried my best to strike that balance between channel gain/level and power amp level, but of course, "soundcheck" is rarely done at full, blasting, 3rd set volume. Anyway, does a simple issue come to anyone's mind when this happens? Wasn't super loud or constant, but enough to annoy. Thanks, and Happy New Year to all.
