The "rude solo" wil only flash if something is soloed. You need to check again as there is STILL something soloed. The left meter is because that is showing the channel that is being soloed. Once you unsolo everything, the meters wil display full left and right as usual.
Hi,
What you need to do is connect (for example" Aux 1 send from the desk to the Left Input of the alesis. Then connect the Left and right output form the Alesis to Auxilery return 1 and 2. You can just use the left ouput and use aux return 1 if having mono effects is ok.

These must be one of the most fault prone speakers ever made. Disconnect the power supply from the amp and see if you can get it working then connect it back up but don't hold your breath, they regularly fail taking out the output stage which in turn takes out the PSU so check the amp with a limited and robust PSU or use a variac on the mains to test.
Take the main outputs into a stereo input (or a pair of mono inputs) on the Peavey - without knowing which Peavey I cannot tell you further info re set-up but as you'll be sending line level signal you'll need to back off the gain on the channels you input to on the Peavey
Is this a new problem? In other words, was it working correctly at some point?
You ned to isolate the problem. Plug a different source into the speakers and plug the mixer into a different amp/speaker. See which part isn't working correctly.. Either way, it's likely you need to take the part that's not working to the shop. You can contact Mackie to find the nearest service center. Service Locator Mackie
That sounds like the amp board died. Mackie parts can be hard to source, and Mackie is really slow to ship, so I suggest taking it to a Mackie authorized service center. Here's a link-

More in likely a voltage drop in the club, and the mixers power transformer was fighting for power, so it's brunt or burning up, also there are capacitors that filter the AC transformer hum, they Probably need to be replaced, this can be fixed tho, parts and labor might not be cheap...
