I know this is an extremely noobish question, but I've searched and can't find much to help solve my simple dilemma.
I just received my Saffire PRO 40 a couple of days ago, and I've finally gotten around to hooking it up and everything. I just want to test it really, not trying to record. So I have my SH-101 plugged into the Saffire, via a Mic/Instrument Input with a 1/4" Jack. I have my Monitors hooked up to the Saffire via RCA -1/4" Jack cables, unbalanced inputs to the Saffire's monitors slots. I've installed the latest drivers (2.0), the software, firmware, everything, without a problem. I have my devices set-up so that the Saffire is the default audio device. Lights are turned on on everything, volume levels appear to be ok. I can play any of my instruments with headphones, so its not the 101. Yet, when I try play it through the Saffire, I'm not getting any sound.
So, uh, what am I doing wrong here?

Am I using the wrong cables? Is something plugged in incorrectly?
