  1. So I’m being requested from dailies to work in pull up 48.048 / 24fps since the DP wants to shoot @ true 24fps to reduce the possibility of flicker with lighting set ups. We are not shooting on film and footage will be pulled down 1% along with sound to be edited and broadcasted at 23.98.  The dailies company said this is somehow common with Canadian DP’s who feel this is a solution to mitigate flicker issues.  So, The dailies company wants to modify my sound rolls and sample rate convert my Cantar X3 files back down with SD’s Wave agent before hitting editorial to get it all back down to 23.976 and assures me it will be seamless and not affect sound. What’s odd to me is there doing all this just to accommodate the possibility of flicker and it’s not even a heavy VFX show.  I feel like this could create a whole heap of issues not only in my cart workflow with Dante sample rate sync with clocking and pro tools playback but it could also create unnecessary confusion down the line with audio post who will want to work with the original sound rolls.

  2. Hi Everyone,


    I have what I hope is a simple technical question I was hoping to get assistance with.   If I have a recorder in particular a Cantar mini running at 48.048khz sampling rate ( pull up work flow request ) and I have a mic pre amp with an AES output connected that does not have the pull up setting @ only 48khz ( i.e. Sonosax M2D2 ) are there any drawbacks to the AES signal.     I'm hoping & assuming the M2D2 is receiving clock from the X3 by default via the AES signal, therefore the clock is resolved to 48.048khz and is therefore a non issue,  or perhaps I'm missing something.

    Are you all using the 822 with just whips in a bag or are you using antenna distros?  Just curious about the 822 as it does seem like a solid performer for bag use given how you can use any lectro transmitter and put as many as needed per a given job in a bag vs always hauling a DSQD around.

    Use mine with a distro from a PSC 6 pack, performance is rock solid with digital hybrid.

  4. Bringing this topic back to life.  Trying to resolve RF related issues on my beloved 50’s on my current show.  It seems to mostly come from remote RF dimmers on lite mats and or a very busy high RF noise floor modern film set.  Both 50’s are latest model, Allen screw at connector is snug, gold pins all there, etc.


    My next step is try some jumper cable / connector mods and variations to help further shield the signal from the RF interference prone 50’s .  One thought is use an EMC connector on one end of a jumper that goes to our HMa which is from what I understand a ferrite bead which is simply a low pass filter around 10k.  I could see this solving high pitch buzzing issues but I’m also thinking of the lower swishy/bubbly type sound people have described here that also comes up?


    Anyone have experience practical advice on RF connector shielding and or EMC connectors.  Or any other solutions that haven’t already been mentioned here.  Also is there such thing as a MKH50 RF tune up at the mothership if they are the newer variety?  




  5. Wireless is one of the largest investments we make as production sound mixers and we’re seeing less and less 3rd party compatibility modes with manufacturers pushing digital systems.  At least a few cart based mixers here in Atlanta have adopted ( or more like switched ) to the Shure Axient into there cart based wireless. I think this partly comes from frustration from the current RF landscape and the desire for smaller transmitters with greater feature sets.  I’m sure Shure “no pun intended” will gain a lot of traction with these new bag based camera compatible receivers.  I will wait and watch patiently as these systems evolve and develop as they become more wide spread and am looking forward to hearing unbiased user feedback.

    3- I hope the comms buttons aren’t merely toggles like they were in the 6 series, performing different functions depending upon the menu you are in. Please be dedicated comms like in the 7 series. 

    It appears as if the com1/com2/slate and PFL's are the toggle switches like the CL9.  At least that's my guess on what those may be for.

    If it’s simply for meters and track names that seems like a bit of a waste of physical space. That thing is going to eat up like 5ru with the screen flipped up. 


    I think what they do with the screen is going to be critical to the success of the unit.  I feel the screen size on the Scorpio is way to small for a cart based recorder, so if you can navigate with this larger screen and elminate the use of an Ipad it would be amazing.

    They aren’t around anymore. I tracked the owner down and he told be they closed the business. Real shame. They made the best drawers.

    Agreed, I was fortunate to build both my carts about four years back with their drawers before they closed up shop.  What is everyone else buying these days?

    I wish I knew more about these mic pres versus the Kashmir pres.  I could find out on a trial basis.  There seems to be little information on the difference.  And I suppose there may be other elements that could affect the overall sound quality.  Also, apparently not internal 32bit processing on this or the scorpio.  Please correct me if I am wrong.


    Congrats Sound Devices!

    If they are the same as Scorpio they sound great AB.  Sound Devices themselves said the Scorpio’s pre amps are the best sounding in their 20 yeAr history.

  9. In Avid/ProTools workflows even if the AAF from editorial is 24 bit as long as the source files in the sound roll are 32 bit, and the TC from the exported AAF is intact the dialogue editor should be able to work in the 32 bit session and replace those 24 bit tracks.  Providing the TC is intact when it hits the dialogue editor Pro Tools Ultimate/HD allows you to easily replace that by reading the TC and auto replacing it and importing from the sound roll.  Replacing the AAF files from the sound roll is pretty common workflow practice on larger scale projects anyway for a variety of reasons.  I will say that having the option to record both formats simultaneously would be an excellent future feature to ad to our flagship recorders X3, Deva 24, Scorpio. Etc

    Actually, there is no such mic, nor a pre-amp in existence, that has that kind of dynamic range.

    Perhaps I'm living in the past, but surely not a newbie.

    More bits / more dynamic range = lower noise floor.

    So if you record, let's say at -40dBFS, just to take advantage of the headroom, then bring it back up to -8dBFS, you also brought up the noise floor by 32dB. Granted the converter noise floor will be extremely low, but anything else in the room, including you mics, pres, traffic outside etc are also brought up 32dB.

    Again, I could be wrong, so please explain to me what I am missing.

    Your not missing anything, excellent point about relative levels. Most of the noise floor issues on a film set are all purely acoustic, so once again gain staging and signal to noise is important and it always will be.

    Here is an article with both the sound files and visual representations of files that were correctly, over, and under recorded to three separate tracks in the MixPre II. This gives an idea of the gain invariant nature of 32-bit recording.



    Jon, thank you for posting this comparison. I just listened and adjusted the raw poly file here in Pro Tools in a 96k, 32bit Float session with a Apogee Symphony.  I am hearing no discernible difference in the signal to noise input on the tracks when comparing the optimal gain setting to the one set 40db below.  Very impressive!


    However, I will say that I thought I heard a better sonic performance and detail from the track recorded at the optimal level.  It was very subtle but noticeable to me.  Just to make sure I wasn't fooling myself I through it 180 degrees out of phase with matched levels and could still hear portions of the track coming through. One could still take the position that the pre amp / converter still prefers an optimal input level.   But I will not deny that the 32bit float has many advantages in recording and post.  Congrats to you and the team!

    And so, Aaton, Zaxcom, Sonosax, and now Sound Devices all say that gaining is not really required anymore. 

    I've never heard any of these manufactures say that that gaining is no longer required on a mic pre amp.   Maybe in the marketing literature as a way to sell a certain type of converter or recording system as far as dynamic range.  But that's only one small piece of a much larger picture.   Even if one thinks that they could hypothetically get away without proper pre amp gain based on this ridiculous application theory that input trim levels no longer matter, any under or over modulated input signal would therefore create more issues as it runs through the signal chain of the full system.  Maybe as an experiment try ignoring your input trim levels on a professional job and see how long you hold on to that job before post gets a hold of you.

    i tested the D2QD, sounds great!  it weighs about the same as two 411a's, but why in the world did lectro put the antennas on the back? by putting it on the back you just eliminated bag use and minimized it to only cart. very sad.

    The ergonomics of the anticipated SRD, not to mention the slot mount advantages make something like this way more ideal in a bag.  The other side of this is that antenna's on the front would have made cart use awkward as well, which is really it's intended use.

    You just connect the mic and it will convert whatever comes out of your mic, whether it’s the mic‘s noise floor or the loudest sound the mic can convert, the TrueMatch just converts all of it truthfully. So, no more need for a preamp and thus for gain staging. 

    If there is no mic pre in the signal chain and it truly goes directly mic level into a AD converter that can handle these low input levels then you are technically correct. But only in theory not practical application in production sound workflows.  No matter how extensive the 32 bit float point dynamic range is in the digital domain the fundamentals of proper gain staging and signal to noise still apply for all production sound systems on all analog input/output points in a 32 bit float workflow for those who wish to achieve outstanding audio.  What concerns me is this marketing hype of “input trims no longer matter”  It’s simply not true and it sends the wrong message for those who may not no better.  

  15. Thanks Jon, I just think it’s important to point out that your analog input signal level is not directly equivalent to your signal to noise level on any given mic preamp.  For instance if you were to record at a relatively low level into a analog mic pre that had 32 bit floating point converter stage, the signal to noise level of that that track when you bring it up in post would be much less ideal then say a properly gain staged analog input that maximizes the use of the analog pre amp to its fullest. I won’t deny that 32 bit has some excellent advantages like you mentioned but I think it’s important we send the clear message to younger up and coming mixers and recordists that proper gain staging on the front end mic pre does matter, no matter what the bit depth your recording in.

    Anyone to report on the actual sound of the new preamps of the Scorpio?

    I was very disappointed by the sound of the 688, that I found harsh and bland compared to those of the 7 series.

    I am interested in subjective reports of course 🙂


    I was able to compare it directly to the 688 using a passive whirlwind splitter and a hard lined Sennheiser MK50.  Two observations are that the headphone amp is noticeably better and when I put the 48k 24bit files in the DAW its quite noticeable that the Scorpio is an improvement over the mic pre amps of the 688.  It sounds more open and has more definition and detail to my ears.  Sound Devices has stated that this is the best pre amp design to date.

    Any additional feedback with the D2, especially with using it in a bag setup. 




    The location of the two BNC antenna inputs, XLR /Dante outputs, and power is less ideal for a bag workflow and will be cumbersome, A slot mount SRB,SRC,A10, etc solves all that.  And my guess is that with the digital winds of change the tumbleweeds will be bringing more to the slot mount design in the digital world such as the speculated SRD.

    Would be interesting if its comfortable to write a sound report inside the device. With the 788t it was practically very bad so i chose the ambient solution via beetle, but it lacked very much with reconnection speed of ipad and keyboard as well as the option of just writing comments to the previous take.


    I’m sure it will have a sound report feature with the new included app.  I’m assuming it will be along the lines of wingman which which works great once you got a workflow down for using it for delivery.

  19. Thanks for the clarification on how you guys will implement the mapping on the Platform M+ and congrats on the new Scorpio launch!    As you know I'm primarily a TV mixer for scripted work and high track counts for us are the norm.  What I would like to see is something like similar to the CL12 + trims with high quality P&G type faders.   Bank switching or adding an extra controller is not practical in fast pace workflows.   Just yesterday I easily exceeded 8 faders and I couldn't imagine bank mixing or having to set up a second controller.   We're also having to coordinate with our wireless which typically has fixed input routing to the recorder so it's not always possible to use a 1-8 type logic since certain blocks may be further down the line /etc.  Also have questions about com workflow which I'll post later on.

  20. I feel ( or want to feel ) that Sound Devices has a control surface in the works.  Looking at this Platform M+ it's obvious this was designed with the home studio daw user in mind.  None of the typically buttons or production type workflow/layout we need.  I'm becoming more and more happy with my 688/CL12.  May just buy a second for a deal when all run towards this product.
