As follows:
Volume on both L2m's are at center detent on both speakers.
Connected via L6 link.
Connected with Hosa AES/EBU cables. No right angled connectors. All connectors are secured.
On kick out stands as monitor.
Helix does not cut out, only L2m's.
Power indicators on front of L2m's go off and on. No clipping, just speakers are on and off.
Frankly, I think the L2m's are fine, I think it's an incoming electoral power issue.
Have connected the units with a Tripp-Lite line conditioner and it seems to be working well. Just wanted to find out if anyone has had a similar issue.
