  1. Sound Devices Mix Pre-3 and Mix Pre-6

    As an option having MS ISOs and MS>LR for the mix would be welcome, of course, even if not something that I would use personally: this is rather different than mjw353's first post seemingly wanting this as the only option (and, indeed, suggesting that this was SD's intention and, by implication, another MS bug [there was, of course, a bug in the early firmware relating to use of the pan controls in both MS and stereo linked modes]). Cheers, Roland
  2. Sound Devices Mix Pre-3 and Mix Pre-6

    Hello M, My Mixpre-3 functions as you describe, but I can't see the problem: if I am recording MS linked I want LR stereo on ISOs and on the main mix and likewise MS on both if recording MS unlinked and simply monitoring as LR stereo on headphones. If it only decoded MS to the mix then you would have issues if recording other channels at the same time, and plenty of scope for confusion. Looking at the Mixpre-6 manual (in case there is a difference) I can't see where it states that the ISOs will remain if MS linking and, indeed, I can't see how the gain staging with linking option (p. 21) would work: please could you clarify? Cheers, Roland
  3. Line level recorder

    The Zoom F4 isn't such a 'no brainer' in the UK, where the OP is based, and is only £90 or so cheaper than the Mixpre-3: as you want a line-level recorder not a digital bit bucket, I'd go for the Mixpre-3's better headroom on line-level input and the lower self-noise. Assuming that the need for line-level recording means there is a very good preamp feeding the recorder, the Marantz PDM706 or other cheaper options (e.g. Tascam DR70D) would seem unwise: if this isn't the case, and there is some other reason for the line-level signal, then these might do the trick for a lot less. Cheers, Roland
  4. MixPre-6 or a second hand 552?

    No implication that it is digital gain (and the SD spec for gain 'Total, Mic-to-recording (max): +96dB') is consistent with non-digital gain (as, indeed, supported by actual use). See earlier discussion: Cheers, Roland
  5. Sound Devices Mix Pre-3 and Mix Pre-6

    Hi dkm, I agree with Chris that, even if all else was equal in the preamps, the EIN differences would be all but indistinguishable, not least since, if you remove the mix of dBV and dBu the two are more obviously closer in spec: the Mixpre 3/6 specs are -128dBu and the 633 is -126 dBu, and the latter is not a reason to hold back on a 633. Cheers, Roland
  6. Sound Devices Mix Pre-3 and Mix Pre-6

    And just to clarify, in my test phantom power on or off made no difference: either way there was no issue. Cheers, Roland
  7. Sound Devices Mix Pre-3 and Mix Pre-6

    OK, have checked: my Mixpre-3 shows the same level of noise in each channel (each bobbing up and down from 1-3 steps/lines of pixels on the LCD - about 2-3mm max on the screen). And all drop to (equal) extremely low noise when plugging in a low self-noise mic (4.5dba). All entirely as expected. Hope this helps. Cheers, Roland
  8. Sound Devices Mix Pre-3 and Mix Pre-6

    SD have just released a firmware update that apparently corrects the MS and stereo-linking bug, and all the other reported bugs that I am aware of, plus more to boot, and adds a few very modest changes, which is excellent news. Cheers, Roland
  9. Sound Devices Mix Pre-3 and Mix Pre-6

    Now that's good news for any non-ipad types, such as me: SD have announced Wingman is now available for Android! Cheers, Roland
  10. Sound Devices Mix Pre-3 and Mix Pre-6

    Give or take the current bug (which prevents turning off the LR mix while using custom mode to have the channel knobs control gain on ISOs), obviously we have this already, so creating a new mode perhaps called 'Basic - ISO' as opposed to the current 'Basic [- Mix]' wouldn't add functionality, but just save that initial custom setup. That sounds harmless enough, and there is indeed room for a fourth mode button on the mode selection page of the system menu, but just I wonder if people would then say they want various different options under this mode (i.e. basic or advanced for channel, headphone, record, metadata and outputs) and not those given to them: which takes us back to the very useful custom mode (not so 'strange' really). The fact that you say you would want this 'simple' mode, plus 'with complete ganging control (and eventually ganging with offset', and that Robert, above, wants the simple mode with 'ISO output for headphones' says it all: you want channel knobs controlling the ISO gain but with custom set ups! A few bugs apart (I'm especially keen for the MS/stereo-linking Mixpre-3 pan bug to be fixed...), I think SD have got the functionality spot on. That said, expansion of the manual to cover all options (and to explain more about the gain staging - with a block diagram - etc.) would make things more understandable for users. Cheers, Roland
  11. Sound Devices Mix Pre-3 and Mix Pre-6

    I don't see why this implies digital gain at all, but, rather, a combination of trim/gain and fader in one control: the advanced mode gain range is 6db-76db, so -14-96db is this plus or minus 20db of fader gain/attenuation. A block diagram would be useful for understanding the Mixpre-3/6 gain stages, but the proof of the pudding is in the eating: setting up my lowest noise mic (4dB-A and 35mV sensitivity) with 76db gain in advanced mode, I have just compared this to 76db gain using the channel knob in the custom mode under discussion (i.e. both recording to ISOs) and there is no discernible difference. Following on from this, I then tested advanced mode with the same mic at full (76db) gain vs 56db gain plus 20db fader: as expected from the above, there was no discernible difference. Which is all very good news. Hopefully others will find the same. So, I'm still very impressed by the Mixpre-3: once the MS (and 1-2) linking pan-related bug (of this model only) is resolved - hopefully very soon - I'll be a very happy bunny! Cheers, Roland
  12. Sound Devices Mix Pre-3 and Mix Pre-6

    I've been using the Mixpre-3 for mid-side recordings, both encoding to stereo and just for headphone monitoring. What I couldn't understand is why the pan controls for both channels 1 and 2 remain active (and not greyed out) in MS-linked and, indeed, stereo-linked modes: see pic of channel 2 in MS-linked mode. SD have confirmed that this is a bug (and that it doesn't apply to the Mixpre-6) and suggest that, while a fix is awaited, make certain to set the pan controls to centre: edit - I've just tested the latter and this doesn't seem quite right... Cheers, Roland PS Mike and Paul thanks for clarifying the custom settings for post-fader ISOs.
  13. Sound Devices Mix Pre-3 and Mix Pre-6

    It is not something I plan on using either, and I very much agree with your feature suggestion. Cheers, Roland
  14. Sound Devices Mix Pre-3 and Mix Pre-6

    could you try to see if you can make this work? I have tried this and it works to some extent in that the ISOs can be armed as Paul says (of course, you also need to set the gain option to basic in the custom setup). The channel knobs then give a 'gain' range of -14-96db, which is, of course, how they function in basic mode (where there is no separation of gain/trim from fader levels): they do not adopt the range of gain/trim in advanced mode (6-76db). You also have the limitations of basic mode for channel settings: i.e. you cannot link channels, pan is only L R or C, and low cut is on or off (rather than with settings for 40, 80, 120 and 160hz). Hope that helps. Cheers, Roland
  15. Oktava MK-012 any thoughts or comments on it

    Just thought I'd add that I have found the low-cut filter for the MK012 far too noisy to use. When I queried the noise (I bought one in April with the 'movie set' from Oktava online - Europe's main dealer) Natalia Kuzmenko agreed about the self-noise, and said they'd changed components to no effect. Bill Sitler also agreed about the noise and the lack of mod, and, as a consequence, doesn't list them on his website. I just do the obvious and use the low-cut (which is before the preamp stage) on my SD preamps/mixers. Cheers, Roland
