Mike,
Are you talking about this card?
http://www.emu.com/products/product.asp?product=2210&category=754&maincategory=754
This has 2 xlr ins and 6 1/4" ins. If it only could record one channel, why would it have 8 inputs?
Even the 1212M has 2 1/4" ins(plus 2 more ins via S/PDIF, and 8 more ins via ADAT, 2+2+8=12). Again, why would it have 12 in's if you could only record one at a time?
I have been looking at this card for many months and haven't heard anything like this.
I seriously think you bro doesn't have the drivers installed right or he isn't using the Patchmix correctly.
Look here for more info:
