euphemia Posted May 10, 2014 Report Share Posted May 10, 2014 Hello, I am trying to send a 1Khz tone to a Black Magic camera. It doesn't have a VU meter and all it has is a percentage "level" in the audio menu of the camera. Any thoughts of what would it be the equivalent of the 1Khz tone in the camera's percentage "VU"? Thanks Quote Link to comment Share on other sites More sharing options...

Wandering Ear Posted May 10, 2014 Report Share Posted May 10, 2014 Set your tone to full scale, turn it up until it clips, then back off. Quote Link to comment Share on other sites More sharing options...

Marc Wielage Posted May 11, 2014 Report Share Posted May 11, 2014 Audio settings are on page 19 of the manual: http://www.blackmagicdesign.com/media/5813056/Blackmagic_Camera_Manual_July_2013.pdf I like Blackmagic Design for certain things, but I'm baffled as to why the audio and timecode sections of this $3000 camera are so horrible. They did get it right with the newer Ursa camera (except for the giant 10" viewfinder). Quote Link to comment Share on other sites More sharing options...
euphemia Posted May 11, 2014 Author Report Share Posted May 11, 2014 Great Marc, thanks for the input. And yes the audio settings are very lame! Quote Link to comment Share on other sites More sharing options...

sounddguy Posted May 17, 2014 Report Share Posted May 17, 2014 Ran a quick test on the Pocket Cinema with these results: -20 dB tone from SD-Mx Pre D to Camera LINE input Gain Pre D output level set to BM% Line Mic 30 -16 -37 dBfs file level 40 -13 -34 50 -11 -32 60 -9.5 -31 70 -8 -29 80 -7 -28 90 -6 -27 100 -5 -26 Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted May 17, 2014 Report Share Posted May 17, 2014 "-20 dB tone from SD-Mx Pre D" Assuming the MixPre D is like other SD products, wouldn't the calibration tone be 0VU on the MixsPre's meter, which would equal '0dBu' at the XLR (in line mode)..-20dBFS would then be the 'normal' setting on the following recorder, providing it has full range.meter. (dBFS) Or am I missing something? (my mind for instance) In any case, that's good info to have, Thanks SG Quote Link to comment Share on other sites More sharing options...
studiomprd Posted May 17, 2014 Report Share Posted May 17, 2014 RR: " Assuming " assuming is always risky...Rick. when discussing dB's the scales must be defined... Thus -20dBFS = 0dBu may be correct... (it depends) Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted May 17, 2014 Report Share Posted May 17, 2014 Here's how it goes. "0" is .775volts ac as measured across pins 2 & 3 of an output xlr. On older analog mixers like the 442 it lines up with the "0" markings which is mid point on the meter scale and you had to do the "0" to -20 math in your head. Now the "0" mark is at the top of the scale and the -20dbfs mark is mid scale where the tonelines up to now. Nothing has changed, same output level just a different designation.

Philip Perkins Posted June 8, 2014 Report Share Posted June 8, 2014 I mostly have fed the "midsize" and small BM cams from G2-type RX. They seem to be happiest getting a lightweight line level, which is pretty much as loud as a G2 can be anyhow. The audio was less noisy working this way than sending it mic level (real bad). philp Quote Link to comment Share on other sites More sharing options...
kstrahm Posted October 28, 2014 Report Share Posted October 28, 2014 Working with a BM tomorrow for the first time, and they want scratch audio. Good to see this thread on here. Thank you. Quote Link to comment Share on other sites More sharing options...
chrisnewton Posted October 28, 2014 Report Share Posted October 28, 2014 There is a previous thread about level setting on BM cameras. my experience: the newest firmware has meters showing. also, playback is now possible on camera (previously unavailable). the meters have -24 and -18 markings. I only used mic ins on camera, not line. headphone return was OK, just a bit low. I fed the pocket cam with a Sennheiser G2 at lowest mic level out via 1/8" cable. The bigger BM camera on the shoot was fed mic level via XLRs into the attached Wooden Camera gizmo. all good. recorded everything to a 633 as well. haven't heard anything back except that the cheque is in the mail. (very good client actually). Quote Link to comment Share on other sites More sharing options...
