T Spear Posted February 3, 2020 Report Share Posted February 3, 2020 Hi folks, My mix pre 6 II is not behaving at all with timecode. I can not even get it to roll time of day timecode let alone jam.The screen just reads all zeros. Once trying to jam the screen actually came up saying 25 to 25 (as in frame rate)is not supported! It is on the latest version 6 I can set the aux in to receive timecode and the display then matches my ultra sync one but am unable to even jam to this. I have owned and extensively used SD gear since the beginning (442) and have never had any timecode issues. If anyone can offer up a possible fix in menu settings that I am unaware of, or has had this issue addressed by the good people at Sound Devices please let me know. Thanks.

Johnny Karlsson Posted February 3, 2020 Report Share Posted February 3, 2020 Hey T, it would be easier to try and answer your questions if you provided some pertinent info. For example; your current TC settings... and what are the steps you have taken in attempting to get it to jam? Quote Link to comment Share on other sites More sharing options...

Are you set to Record Run perhaps? 2 hours ago, T Spear said: I can set the aux in to receive timecode and the display then matches my ultra sync one but am unable to even jam to this. Double check your USO is not set to mic level? Would be an odd but maaaybe possible bug, that if at mic level the TC signal is perhaps strong enough to be picked up for a moment to be read (& thus displayed) but not quite strong enough to be jammed to. A totally wild theory, but worth double checking as I know you can change the output strength of the USO. Quote Link to comment Share on other sites More sharing options...
T Spear Posted February 3, 2020 Author Report Share Posted February 3, 2020 Thanks for the replies so far. My preferred workflow would be to have the mix pre run as time of day timecode and jam my for camera timecode units by switching the mix pre stereo audio out to ltc out and jamming my timecode units to the received timecode outputting from the mix pre 2. I have set the timecode to time of day 25 fps and the stereo out to LTC out. The mix pre counter stays on 00:00:00:00 No timecode is detected by my ultrasync or moz gear. I can only seem to get the display to show timecode when I set the aux input to timecode and input timecode from any one of my units. Ultra sync or Moz Gear. My mix pre 2 seems to only work like a mix pre1! Not being able to jam the mix pre from the aux input or output timecode seems to confirm some issue. Has anyone had timecode issues similar to this? Thanks Quote Link to comment Share on other sites More sharing options...

Always a possibility, are you 110% certain you've got a Gen2 recorder? 4 hours ago, T Spear said: Not being able to jam the mix pre from the aux input or output timecode seems to confirm some issue. An original MixPre Gen1 recorder could be jammed to an external TC source though. Quote Link to comment Share on other sites More sharing options...

Jim Rillie Posted February 3, 2020 Report Share Posted February 3, 2020 Sounds like it is n Record Run, to me, and of course, as Johnny says TC in and Jam. Quote Link to comment Share on other sites More sharing options...
T Spear Posted February 3, 2020 Author Report Share Posted February 3, 2020 Hi Thanks for your replies. I wish that it was as simple as being in record run. Have tried all possibilities mentioned and more. Looks like I have a sick puppy. Quote Link to comment Share on other sites More sharing options...
al mcguire Posted February 4, 2020 Report Share Posted February 4, 2020 Does the MixPre 6v2 have an integral time code generator ? I have V1 and I use a Denecke box for TC, and it took a call to Sound Devices wonderful tech wizards to get me set and running. Quote Link to comment Share on other sites More sharing options...

Display Name Posted February 4, 2020 Report Share Posted February 4, 2020 Would an option to run one of the the USO as master/TX-master? Can you run the USO with LTC out to the MP II on LTC in and get the MP II to recognise the TC? Quote Link to comment Share on other sites More sharing options...
T Spear Posted February 4, 2020 Author Report Share Posted February 4, 2020 Hi All, Thanks again for your replies. There is nothing much you can do wrong with these Mix Pre2s if they work as they should. My one will be heading back to sd before I even got to use it on a really simple shoot. I have re updated the version 6 software and the timecode rolled as time of day and all syncing options worked however upon a power off and back on the line of zeroes returned with the same timecode issues. I have uploaded some screen shots. My main question was that has anyone had this issue or similar with timecode and a mix pre 2. Thanks.

Display Name Posted February 4, 2020 Report Share Posted February 4, 2020 "Jam GEN to AUX 1" is when you want to Jam the MixPre from an external TC source feeding its TC on AUX 1 input, right? If you try that you need to set the USO to be the TC gen and output LTC on one of it's two ports. Quote Link to comment Share on other sites More sharing options...
IronFilm Posted February 4, 2020 Report Share Posted February 4, 2020 That DIFF is surely not correct? Look at the three numbers, the math doesn't make sense. Quote Link to comment Share on other sites More sharing options...
T Spear Posted February 4, 2020 Author Report Share Posted February 4, 2020 Hi again, As you can see from the pics my mix pre doesn't seem to know what time it is. Off to the shop. SD service is very flash. Thanks for your ideas and comments. Quote Link to comment Share on other sites More sharing options...
TVPostSound Posted February 5, 2020 Report Share Posted February 5, 2020 After 4 hours powered off, mine boots with 00.00.00.00, but a split second later, I get a timecode was reset notice. Time of day returns. So I guessing your timecode is not resetting. Have you tried downgrading the firmware, the upgrade again?? Quote Link to comment Share on other sites More sharing options...
Mattias Larsen Posted February 6, 2020 Report Share Posted February 6, 2020 Hmmm.. I dont have the V2, but V1 just States duration in the record window instead of TC time, maybe there is another mode that should be used? Quote Link to comment Share on other sites More sharing options...
frankaudio Posted February 9, 2020 Report Share Posted February 9, 2020 Time of day is what your current selection is, not what you will select if you touch the selection. What other options do you get when you select mode. Quote Link to comment Share on other sites More sharing options...

kavenzmann Posted January 26, 2021 Report Share Posted January 26, 2021 FYI: I'm using my MixPre6 II and 2x Tentacle Sync E's for a 2 week shooting in east africa right now. Everything seems to work as expected. I use the MixPre as the TC Master and sync the 1st Tentacle with a 3,5mm mini jack cable from the Stereo out as described here: https://tentaclesync.zendesk.com/hc/en-us/articles/115004293485-Sound-Devices-Mix-Pre-3-Mix-Pre-6-and-Tentacle-Sync-Workflow- The other Tentacle is then synced via the app. Can't really see any problem. But only if the editor tells me all is fine I know it works correct. I'd just feel more comfortable with 3x Tentacles as the MixPre does give me a 'TC was interrupted' or so message from time to time. But I never can see any TC mismatch by eye. Also, the MixPre just freezes sometimes when powered with a powerbank. It always happens right after starting it sothat I can avoid issues, but I don't feel very comfortable. That might be an issue with the powerbank I use, as I did not see that behaviour with my Sony NP-F style batteries or AA cells. What I really love: I put a little USB stick into the USB-A port for s constant backup on a 2nd media. You can't really control if it works, but it never let me down until today. At the end of each day I just put another USB Stick into the MixPre. Then all media is copied to that stick that serves as a transport drive for the backup station. This way I never have to fiddle with the SD-card. Quote Link to comment Share on other sites More sharing options...

I use the Anker PowerCore+ 20100 that Sound Devices recommends. I've run it non-stop for hours and it's been flawless. Quote Link to comment Share on other sites More sharing options...
kavenzmann Posted January 27, 2021 Report Share Posted January 27, 2021 It's just a cheap one I already had for other uses. It works fine even for hours of continous use. But the freezes seem to come from the powerbanks energy management. Definitely an issue, but one I can work with while having this gig in africa right now Quote Link to comment Share on other sites More sharing options...

But the freezes seem to come from the powerbanks energy management. Definitely an issue, but one I can work with while having this gig in africa right now I would stick to a known good powerbank. The MixPres are power hungry and USB power is non trivial. I was experimenting with using a MixPre as an audio interface for an iPad (to run SMAART tools on it for live sound) and due to the flaky USB power provided by the USB to lightning adapters I had startup problems (it took several attempts to boot!) and when the AA NiMH ran low the MixPre entered a reboot loop. Interestingly, the reboot loop didn't seem to affect the audio flow from the microphone to the iPad. Turns out that the FPGA keeps pumping samples once it's been configured. That was funny Quote Link to comment Share on other sites More sharing options...
