4K BMCC


Recommended Posts

I have a friend who has a BM cam. We're going to do some tests to figure out what general audio level it wants, since it has no meters, by "cut and try".

philp

I used one the other day, it was connected to an Astrotech viewfinder, and audio meters were available in there - via sdi.

Sending from a G3 set to -12dB, mic level (IIRC) I had the gain slider somewhere around the 50% mark.

Keep in mind this was just for a scratch track so I did it quickly.

"For audio you get 1/4” jack mic/line inputs plus 12V to 30V DC input, a 3.5mm headphone socket and LANC remote control. And with a built-in uncompressed audio recorder you can eliminate post audio synching altogether."

 

I don't understand their fascination with 1/4" jacks. The last line made me laugh.

Yeah, and when's the last time anyone use LANC? I assume the use of 1/4" is because it looks slightly more "pro" than 3.5mm, but doesn't take up as much internal or chassis space as XLRs. Though with that reasoning, why they didn't just use a single TA5 is beyond me.
