I am trying to set up the best 'Rebel w/ Out a Crew' option I can.

I am shooting bmpcc and monitoring using bmvideo assist.

I have a Sennheiser K6 Combo and shotgun mic (battery powered) (and also have a Tascam D-40)

Is there a tutorial or page that shows the best way to record audio with this set up? Output would be for personal study, vimeo, youtube, etc. Not at all concerned with master sound design and getting to broadcast at this point.

Have no idea what settings to use with bmva audio (Decibels?) or if there is another way. Hooked everything up and seemed to be working but then got a sudden rush of static and feedback .....

Thanks in advance!
