My 18i8 interface has TRS left and right main outs. Just one pair. Due to a lucky find at the local Goodwill, I picked up a set of M-Audio AV-40 powered monitors for $16.99. So now I have a 2nd set of monitors. I’d like the be able to switch back and forth between my two monitoring sets. I’m looking to go as cheap as possible. Passive is fine with me. I’m handy with a soldering iron and not opposed to building my own from an old printer selector switch. I have lots of space in my 19” racks (got one of those studio desks with lots of rack space really cheap from Craigslist years ago).

Anyone else using multiple monitor sets.?
