ok i've got a yamaha mg16/4 mixer with 10 solid state pre's. i can send out 8 channels individually to the motu, and i can mix a stereo pair out through the subgroup out. this is basically 10 channels taken care of. i was wondering if there's a multichannel (like 8 ) NICE pre-amp i can use in addition for a few more in's. the yamaha is fine and clean, but is there something i can use for a few tracks that would further compliment perhaps a few tracks for rock music. (the motu does not have an adat in,, i'm looking for something with line outs if possible. any thoughts and suggestions are appreciated!
