Just to clarify, mic INPUT as well as line input, not just internal mics. The mic in can accept a consumer line level signal but a pro signal would need attenuation.
so you can basically use a Littlebox > Line In and SBD RCA Out > Mic In... how would you set levels for each?
and can you record 2 separate audio files or are you limited to the "Mix" feature?
after I sold my 680, I've been using 2 M10s to record a second source the few times I have access off the SBD
and then having to deal with the drift in post... this would be alot easier
but then again I'm very unhappy with TEAC's customer service after the 680 debacle (sorry that's another thread)
