Any word on fixes for the in-camera audio problems? Are we still bound to using double system because in-camera does not work as advertised?

Are solutions possible with firmware updates BM??

No update yet. But, the settings I use are based on the recommendations of the juiced link guy based on his research:

Internal Mic 0%

Mic (not Line) 80%

then used the juiced link pre-amp set to about half and tweaked based on the subject. I just listened for clipping (which requires good headphones in a loud environment). Also, played back in another environment to be sure it all sounded great and it did. Then in post, you have to tweak the 500hz and below lower end of the spectrum and raise it up to about 12db due to the cameras digital attenuation. Until an update brings us levels and removes that digital attenuation this gets you good sound. I also set my pre-amp to dupe my left channel to the right channel and add a -16db pad as a backup in case of clipping.

So I gotta buy other people's hardware to make my BM product work as advertised? LAME

Thanks for the work-around option. I will continue to use double system sound for the incapable BMCC

The other alternative is to use firmware 1.2.1. Here you can just plug in your mic and for mic input set at 50% (for me at least), you get decent levels recorded and on headphones.
It does have the DC offset problem so you will still have to fix that in post but at least when recording you won't need an external active pre-amp.

My approach with the camera is to keep it's input levels as low as possible, and pump up my preamp (Juiced Link CX231) to its highest level. The resulting recording is a little low, but it seems clean, and has a whole lot of headroom to ramp up gain with out getting the typical hiss when you try to push up the BMCC levels a little bit. My settings are Mic input on the camera at 20-25 % and Juiced Link pushed to max.

Hey Chris,

I'm curious what firmware you're using. When I tried that I found that the audio was clipping rather early. I did some research and found that with 1.3 & 1.4 that setting to 80% on the camera
gives you more headroom. Also, around where on your juiced link do you typically set the levels? Thanks! I definitely want to keep the camera as low as possible.

I turn the Juice Link all the way up. This model outputs in Mic Level, and I set camera for mic level input.

Usually have the JL BMC366 at 50% and the camera at 35% (mic).

Gives me nice -12db at normal booming distance for dialog with a NTG3 or Oktava hyper.

Just make sure you have a REAL balanced connection between JL and BMC - if your cables are soldiered in a different way or if you have a wrong adapter, your signal will be way lower.

Gonna do a blog article wit downloadable preset and examples, as soon as I have some time on my hands.

So the Riggy Micro you had before needed other settings?

exactly what problem are you having Shane? Can you give a description and maybe post a sample?

I had an earlier firmware on the camera back than.

I see, have you tried it with the current firmware you have on your bmcc?

(I'm just wondering if I should get the riggy micro or the bmc366, price difference is keeping me back a bit)

But if you're saying that because of the unbalanced output the riggy micro preamps might be lacking in output I suppose I'll have to save up for that bmc366 (was hoping I wouldn't need to and put more money towards a better shotgun-mic)

Thank you for your time in advance!

PS. Would the BMC366 with it's 2x mini-jack balanced outputs be able to output to 2x XLR (are there cables that make that possible and would I need both of the outputs or would just one suffice?) and going straight into the bmcc is it okay to just use one of the outputs or do you need both? as you can tell I'm not much of an audio guy at the moment..

DC offset issue, like everyone has. last firmware still did not get it clean and full....still sounds digitally compressed.
