I've been doing this way to long to ask such a simple question, but what is the skinny on setting up a pcm 90 the right way with a console. I have a yamaha 02r and I'm using the aux sends to get my reverb signal. Should I use two aux sends and use the two inputs on the unit or is one aux send into one input sufficient. Obviously I'm using the stereo out puts for both situations. When I use both inputs I seem to be hearing a richer return, however I might just be hearing more gain from the reverb. Also on a pcm 90 or 91, how would I use it with the digital input, the 02r doesn't have a digital aux send. Anybody out there?
