I'd like to record the audio on 2 separate (!) audio channels (Mic left, wireless right), directly in to the camera (GH4) If a audio backup is placed on a recorder that is even better.

For years I looked into stuff as the Zoom H6 / Tascam DR-100, etc. I like that the sound is recorded extra (as backup), but it is too much for a one mans show run 'n gun. I also don't want to sync in post. (as an editor will need to do that , and won't be happy with this) . I thought of the DR60, but it is big, complicated, bad batteries, etc. and I don't know if it can feed a stereo audio (separated) channel to the GH4?

So probably you'd suggest a Juiced Link / Beachtek preamp, because a pre amp is important, right?

But the GH4 pre amp (set to the lowest -12) is okay right? So I'd only need to get both channels in the camera. I found the Beachtek MCC-2, and didn't see anything here on the site.

What's your thought? Will this work for my purpose? Or is this not reconmended for a 'pro' . The money isn't the biggest issue, but the 'easy handy workflow' is.

My Pros: - no batteries, small, 3 hot shoes, (receiver, mic, light) - perhaps possible to put below the camera - cheap

Cons: - Would a pre amp be much better? - Mini jack vs (balanced?) XLR (would that be much better)

I also have a sennheiser shotgun with XLR, but it is quite big for the GH4. As the VMP already has 3.5 and sennheiser wireless also has that cable, that seems more logical (and smaller).
