yeah...well said damon. i wasn't even thinking of the processing power necessary for recording 24bits and outputting 16. it's probably over the top for this device,but maybe not? i don't think it is a priority for SD.
does the 148 only have xlr's out or does it have the rca's as well. or is that only the 248? if it has the spare rca out you could just patch your backup from there.
I know a lot of other pre's have an aux output, like the v2 for example. If i ever wanted to run a backup and was actually questionable of the 722's analog output i can just patch a deck/jb3 from there.
