I use an Mbox 2 to record into Pro Tools LE. I'm running PTLE 7.3.x on an iMac G5 (1.8 mHz, 1 G RAM). I have a Roland RE-201 Space Echo tape delay unit--a real one, not a plug-in--and was wondering if there is any way of using it (or any outboard gear) with the Mbox 2. Do I need to get some kind of mixer or is there just no way?

Thanks
