I'm quite aware of that (though other factors come into it), but that's where the test comes into it's own, as that's my working environment. Even a test in a hallway would give some comparative information, as there will still be sound falloff the further you are away from the mic.

In ideal conditions yes. There are ideal working distances for all mics, but when you work in less than ideal conditions, you need to try and maximise what you have. Try sticking a Lav mic on a King Parrot or similar.

I finally dumped down the footage and got to listen to it.

The bad news is I had to boost the fader in Resolve to +7.5 db AND turn my mixer way up to hear the audio.

The good news is even at those insane levels I heard very little noise.

I add this little use case as evidence to bolster the idea that a good preamp between your mic (whatever style mic you are using) and the PCC4k is a necessity to obtain adequate levels of decibels in your recording.

BMPCC4k - JVC GY-LS300 - JVC HM170UA - Canon 80D - DaVinci Resolve 15 - Adobe CC 2018 - Sony Soundforge 11 - Izotope RX6 Elements - Izotope Neutron Elements

There's little doubt that you need a pre-amp of some sort, whether on it's own or built into a recording device. I don't know what's different about my LS-14 and this cheap audio recorder, as the former will not boost the audio without a pre-amp (and the pre-amp won't work on its own), but the cheap recorder does it all and works on its own.

This one appears to allow a plug in unbalanced mic with adjustable amplifier out to headphones. I showed earlier that, a headphone level in to the bimpsy4k provides a decent level at 50%

Rode Pro+ going into XLR via adapter has MUCH more signal. More than 6db I would estimate.

Thanks Richard,

That would seem to correspond well with another poster here saying it was a 12db difference, but with recent updates the 3.5 has been increased by 6db. So about as expected I suppose. Of course that does rather imply that the whole audio circuit needs much better amplification.

At a resellers here in Adelaide the other day I mentioned the perceived sound problems, and the response was that they really thought that BMD would have to come out of the "It's all about the pictures" bubble at some point.

Too be honest though it seems adequate for my useage and is a huge step up from 5D land which is where I’m coming from. Xlr has plenty of signal for boom and 3.5 is fine for scratch.

Since this thread is all about the bimpsy4k audio... I would like to ask an audio question in general that I have had for years.

When editing in post, I can have a strong level on the VU meters but the actual sound level to my ears may not be as loud as a different video clip with lower meter readings. What I am saying is, I have had video clips (or audio clips) that had a strong sound, but the levels did not appear as high as other clips. It is possible the difference was clips made by me versus clips form another source. I always wondered what is it about audio - actual sound presence and meter readings I did not understand.

Shooting at the beach 2 days ago, with just the built in mics of the bimpsy4k, gave me good sound, but the VU meters in post barely moved. I don't know how to analyze the signal as some pro's do. I'll put a link to that video.

Eli, thanks for the reminder about that product. My Sennheiser 416MKH is a phantom condenser mic which I power from the camera. So is the only adjustment I require then to set the device to 48V? +18 decibels is a lot of boost since this is using the XLR audio, not the 3.5mm audio on the BMPCC4K. Would that also be an adjustment on the Fethead or do I just adjust the audio level in camera to suit my needs?

The fethead attached to the mic xlr as an extension and then you attach the XLR cable. it looks like a natural extension of the mic itself. doesn't require a battery or anything... very simple and good preamp level

There are different models of Fathead preamps, one for non powered or battery powered mics (the Fathead requires Phantom power, but does not pass on the power to the mic), and one where rhe 48v Phantom power is passed on to the mic. So you need to get the correct unit.

I expect you'll be able to use the 416 straight into the camera without a preamp. The camera's preamp isn't as good as Sound Devices, but it isn't bad at all.

That would be good, Iain. Certainly the Sennheiser MKE2 lavalier mic won’t need boosting on the AVX system. That’s really improved my audio capabilities recording theatrical performances. If I do purchase a Sound Devices MixPre-6/10T, would be wonderful to add a few more AVX mics.

I just got this Neoteck HiFI Headphone Amplifier. I plugged the Polsen mini shotgun in to the auxiliary input, and the headphone out I put in to the bimpsy4k 3.5mm input. I turned the camera mic level up to 89. With the mini shotgun 3 feet away from my mouth with normal talking the meters were hitting -18. I plugged the mini shotgun in to the camera and I was barely hitting -36. I used Sony headphones to listen to sound quality and there was a little more floor noise, but not much. I will have to take it outside and record something real world. This unit is $30 and has a signal to noise ratio of 100db.

That sounds pretty good. What was the preamp you used? I could not quite make it out, but the sound was quite good compared to how far back you were.

I did a similar test. I had the camera 3.5 mic input set to 89 and the headphone amplifier set as high as it would go. There was a fair amount of noise. Putting the camera internal mics up close to 100 would not have been as noisy but might have had better volume.

Why don’t you guys just use the the mini XLR? That signal is super clean and great pre-amps.

And you can send it to both channels.

There is no 3.5mm unbalanced mic that is going to sound as good as a real professional phantom powered mic into the mini XLR input on the Pocket 4K. I know everyone would like to find an under $100 solution for that problem, but it's just not going to happen. I have used a Sennheiser 416 and MKH 50 into the XLR input and they both sound great, and levels are more than adequate. The 3.5mm input is there (in my opinion) for one reason only, for a scratch audio mic or a scratch audio feed from a second system recorder that only has mic output. There is no microphone other than something with a 24" parabolic reflector that is going to "reach out" to a sound source 15-20 ft away and make it sound "close". Physics just doesn't work that way, and there is no technical solution for bad mic technique. Get close or go home. Boosting signal just boosts noise, and the ratio of noise to signal increases as the distance from mic to source does.

Thank you. I hear all you are saying. Can I say though, that it is not asking for much for the 3.5mm input to have a standard mic level sensitivity? I have a cheap "3 chip" consumer panasonic HD camcorder with 3.5 input that I mount a mini stereo shotgun on, and it sounds great for all sorts of shooting that is not cinema. The mic does a better job than the on board mic. I just thought it was not too much to ask to have a mic input that IS a mic input. What is sooo hard about that? If there were 2 xlr's... I would be silent.

It looks like the 3.5mm jack was designed for LTC timecode-in, rather than audio recording. Audio on the original BMPCC was pretty bad, but the levels were reasonably good, with both onboard and 3.5mm mics.

What I'm skeptical of is the claims here for XLR mics, without pre-amplication. But that testing will have to wait for another day.

Question: If 3.5 is for timecode, that is good. On a pro camera... why give an option if it is a joke? The electronics to digest an unbalanced mic input are not huge. It is quite small. Why can't they just deliver a standard unbalanced mic input like is standard on consumer camcorders? I would be happy with that. I know I am not in a league here only satisfied with balanced phantom powered sound. I'll use it when I need to, but for now, a standardized unbalanced mic input would be satisfactory. Come on Blackmagic!

Rode NTG3 in xlr is fine like I said earlier. It is a ‘hot’ mic though.

Iain, seems decent levels are attainable with the Sennheiser 416 when subjects are not too far away. With the camera gain at 70% there is unnecessary gain added which is elevating the rumble. I don’t think that should be above 50% (no gain) for these tests. Or at least a test using gain should include the neutral setting as well as elevated levels. Maybe you can deal with the rumble in post, but better to keep it lower in capture.

Your test has me feeling confident the BMPCC4K and Sennheiser 416 are fine.

Thanks for this test. At times I’ll need to use the BMPCC4K internal mic when shooting with the URSA Mini 4.6K at the same time. The Pocket4K will certainly provide a good scratch audio track fo syncing and depending upon the distance to the subject, the audio could be usable.

When I’m only using the BMPCC4K, I’ll use it with an external mic.

Right, the gain was set too high for being reasonably close to the mic. There was also some room noise (a refrigerator in the kitchen near by; it was off axis, so probably not as loud as it might otherwise have been). And I was speaking very quietly; about the level of a quiet conversation with someone standing right next to you.

I was surprised that the mic picked up what I was saying even at the farthest distance, although of course it didn't exactly sound good.

Putting 30db of gain in during post will still leave you with more dynamic range than any feature film recorded up to 1990.

Iain, that fridge may help explain the rumble!

Some day, some year, I may actually be able to update my out-dated audio tests when the BMPCC4K arrives and I have the kit assembled. I’m beginning to feel like I really am on that slow boat to Singapore.

I have done some tests too:
I used an Ohrwurm Lavaliere and an Octava MK12 (about 60cm distance)
I plugged both directly into the BMPCC4k (one into the 3,5 in, the other into the xlr), set levels as I would in real live (about -12 dB) ending up with 90% gain for the Lav and 100% for the Octava.
Then I plugged both into my Mixpre6, set levels as above and sent the output to the BMPCC4k (and recorded both at the same time).
Finally I plugged both back to the camera and set levels to 50%. The Lav showed barely up on the Meters the Octava not at all.

I brought all files into fairlight adjusted the levels to the same perceived loudness. The resulting 8 mono files (A1-4 and B1-4) can be download here (15MB):
https://www.net-artworks.de/download/Au ... MPCC4k.zip

Listen and try to figure out which track is which recording?
Which is BMPCC4K 90%/100% in camera gain?
Which is MixPre6?
Which is BMPCC4k with MixPre6 as preamp?
And which is BMPCC4K 50% in camera gain?

The game is on :-)

Did you do any noise reduction? If not.... woW. There is very little noise amplification. I would like to have the files before you went in to Fairlight.

Been thinking of getting this Mic. My Gen 1 Rode Video Mic Pro’s cable is degrading, with its skin peeling off. I’m no cable repair man, nor own a kit to do the job. But even if that wasn’t an issue, when testing, the XLR port still gives better results when using my NTG3. It’s night and day better. But the problem with using that one is that it’s too big to be an on-board Mic. I can see the mic popping into frame with most lenses.

Now the Deity uses 3.5mm, and has an adapter for an XLR connection. I’m curious to know if the XLR adapter gives the same results as the 3.5mm, or if the sound is better. Probably not as good as an XLR to XLR Mic. But if it’s better then what I’m getting with the 3.5mm port, I’ll probably pick up that mic.

Yes. Each time you double the distance from a sound source, its sound pressure drops by 6 decibels.

Brad, the inverse square law applies to area, so at twice the distance, you would have one-quarter the strength or a loss of 12 dB.

No noise reduction at all. I was surprised myself. I can provide the original camera files later ...

That makes sense, but the intensity of sound is inversely proportional to the square of the distance from the source and decibels are measured on a logarithmic scale. See http://www.animations.physics.unsw.edu.au/jw/dB.htm for example, or http://hyperphysics.phy-astr.gsu.edu/hb ... prob2.html for the equations and a calculator.

The correct answer is you lose 6 dB each time you double the distance from the source.

Your first link discusses intensity and sound pressure. The intensity is one quarter, but the link was helpful showing I was wrong about the sound pressure in decibels, 6dB is correct. The second link comes up with the same answer mathematically but uses the term intensity referring to the sound pressure. Thanks for the correction!

I used an Ohrwurm Lavaliere and an Octava MK12 (about 60cm distance)
I plugged both directly into the BMPCC4k (one into the 3,5 in, the other into the xlr), set levels as I would in real live (about -12 dB) ending up with 90% gain for the Lav and 100% for the Octava.
Then I plugged both into my Mixpre6, set levels as above and sent the output to the BMPCC4k (and recorded both at the same time).
Finally I plugged both back to the camera and set levels to 50%. The Lav showed barely up on the Meters the Octava not at all.

I brought all files into fairlight adjusted the levels to the same perceived loudness. The resulting 8 mono files (A1-4 and B1-4) can be download here (15MB):
https://www.net-artworks.de/download/Au ... MPCC4k.zip

Listen and try to figure out which track is which recording?
Which is BMPCC4K 90%/100% in camera gain?
Which is MixPre6?
Which is BMPCC4k with MixPre6 as preamp?
And which is BMPCC4K 50% in camera gain?

The game is on :-)

It seems a cinematographer's forum is more the place for pixelpeeping than for soundpeeping ;-)

Anyway here are the answers and my conclusions:

A is the Ohrwurm Lavaliere (obvious from the bass response of the omni pattern)
B is the Octava MK12 (that could have been placed better as there is quite some interference from the desk and the floor that I could have avoided by angling it differently)
1 is from the MiPre 6 (clearly the best sounding tracks)
So far so expectable.

And now to the surprises:
2 is BMPCC4k direct (90%/100% gain)
3 is BMPCC4k direct (50% gain)
4 is BMPCC4k fed by the MixPre 6

Sound and noise wise they are almost identical. Biggest surprise is #3. I pushed the gain almost 22 dB for A and 30dB for B in Fairlight to match the levels of the other tracks – the noise floor is still low.

Conclusion:
Unless something in my test setup is wrong or I miss something, the noise floor of the BMPCC4k is very low on both inputs. The pre amp seems to be week, but it is no problem to raise the levels in post and get good signal to noise ratios.

So for me the simple solution is: Plug whatever mic you have into the BMPCC4k, don't worry about the low levels and 100% gain and adjust it in post. (And place your mics correctly.)

These findings seem to be different to some other reports. My Question: Are your tracks really unusable after raising the levels in post? Or are you just concerned that the meters are low and the in camera gain has to be set to 100%? (I have cameras and recorders, where this would indeed lead to very bad signal to noise ratio).

And for those how would try the original files from BMPCC4k/Mixpre 6:

Speaking of Ohrwurm, I see he (the maker) has come out with a new generation of mics, including an update of his popular binaural mic. The original Ohrwurm binaural did quite well on the original BMPCC as it was a high-output mic. Now that the new generation is available I'm considering buying one to try on my original BMPCC as a way to capture ambient sound.

Despite widespread doubt and negativity, my simple and inexpensive solution works quite well: https://australianimage.com.au/blackmag ... -4k-pt-10/.

Most of those claims pertained, as far as I know, to the 3.5mm input. And I can confirm that the 3.5mm sound really is unusable without heavy noise reduction. The noise levels were higher than anything you recorded.

Sorry if I missed it, but which input were you using? I tried your files just now, without reading your later account. Watching the meters during the room tone at the end of each clip, it's easy to say that 1A was the quietest, followed by 4A&B. I believe 2A and 3A were the noisiest.
