yamaha 01v (the white one), roland vm3100 or mackie Onyx.
12 CHANNELS? One of the above will work. If the analog mixer has a couple of channels with hiss maybe it should be repaired or cleaned? Having a digital mixer is cool but has it ever occured to you that you're signal is going through analog cables and going through the A-D converters in the sound card?
But yeah one of those mixers should work. BTW they are MIXERS, not daws/hard disk recorders.
