I use a trio of routers in my system: dbx 400X, dbx 200 and Pioneer U-24. Because my preamp - a Pioneer Elite C-72 - has two tape loops, I daisy-chained the two dbx routers then run to Tape 1 loop of the preamp. The U-24 router is used for Tape 2 loop. On the dbx routers, you can use the processor inputs/outputs for other RCA sources (except phono), but then you lose the flexibility of dubbing from those sources to other equipment wired into the router through the same tape loop.
"I almost need a cheat-sheet to figure out all the different combinations." lol I look at my set up and wonder how the surviving family will ever figure it out... the most complicated thing any of them can hook up is a headphone to an iphone
I think I will end up getting a dbx 2 or 400, pretty sure I can make one do what want.....
