I'm surprised your 880 has a fan in it....mine does not.
Analog I/O on this thing sounds very good IMO...better than you might expect
considering the age of it.
Another solution is to make (6) (R880 has 2 ins and 4 outs IIRC) 1 foot lengths
of XLR-XLR cables with the polarity swapped. Connect these to your 880, and
then, connect your snake to them. This would make your 880 appear to be pin
2 hot to your patch bay.
Cheers

Oh, and BTW, you only need to worry about polarity if you're going to interface
to unbalanced gear. Otherwise, its no problem...

TheR880 doesn't have a fan, but I've had my eye on a 480L and it has a fan.

Our '880 also does not have a fan... but the whine from the
controller display drives me crazy!! ;-)

Yeah...that's the inverter that drives the backlight. A competant tech should
be able to install a switch on it, so you can turn the back light (and whine)
off when the controller is not in use.

I may do this. I've got a LEXI MRC that is doing the same thing. I haven't
been able to test it yet because the 110>220 step up converter hasn't
arrived. I found another GC8 on EBay and bought it cheap as a backup. Maybe
one of them won't whine....or maybe both of them will.
