M Sisco Posted October 20, 2017 Report Share Posted October 20, 2017 The Denecke TS-2 that we rented for our production, set at 23.97fps, runs slower than the Ambient timeclock on my Sound Devices 744T, set at the same rate. Neither is in drop frame. Any suggestions to correct this without buying lock-its? Quote Link to comment Share on other sites More sharing options...
BRYAN DAY Posted October 20, 2017 Report Share Posted October 20, 2017 Lock it’s will not correct your slate error unless you propose to feed it to the slate The 744 should be stable, mine has been rock solid for eight years! If the slates a rental switch it out Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ed White Posted October 20, 2017 Report Share Posted October 20, 2017 All Denecke time code products are also world famous for rock solid accuracy. I'm sure you've triple checked all settings, but it sounds like one of them is wrong. Quote Link to comment Share on other sites More sharing options...
Coleman Posted October 22, 2017 Report Share Posted October 22, 2017 I agree with ed white. In the almost 25 years I have been doing this Denecke products are absolutely the most reliable thing I have ever used. Quote Link to comment Share on other sites More sharing options...
JWBaudio Posted October 22, 2017 Report Share Posted October 22, 2017 Seconding Ed and Coleman, it sounds like something may be off in your settings? Also, about how long does it take for the drift to become noticeable? Was either device accidentally powered off for any period of time? And, yeah, if it's a rental switch it out, and if the issue persists then at least you've isolated the issue to your 744T. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted October 23, 2017 Report Share Posted October 23, 2017 All TC clocks can be calibrated one way or another. Ambient made this possible to do in the field with their master unit, Denecke can cal their equipment in their shop, as can other techs....

Glen Trew Posted October 23, 2017 Report Share Posted October 23, 2017 How much drift over how long? I could be wrong, but If I recall correctly, the original TS-2 slates didn't have 23.976, and was available later as an upgrade, which became standard on all TS-2s. Standby for a correction if I'm wrong. Anyway, if you can see the drift after 20 minutes, then it's probably not a calibration issue, but a setting issue.

Very true, and often small drifts can only be seen by taking a picture of the display--the numbers are churning too fast to see much of anything under a second or so.

Yes, that's what I've come to believe the issue is. There is no setting on the Denecke jog wheel for 23.98 or 29.97. Just the round numbers, which would account for the amount of drift occurring. We assumed when it arrived that 24 meant 23.98, but obviously not. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted October 24, 2017 Report Share Posted October 24, 2017 Nope. That baby needs the 23,98 upgrade. Quote Link to comment Share on other sites More sharing options...
Glen Trew Posted October 24, 2017 Report Share Posted October 24, 2017 Denecke has always had efficient abbreviations. For 23.976, they simply use "23", which is definitely not 24. However, the TS-2 always had 29.97. In a pinch, you can set your slate to 29.97, as at least there wouldn't be any drift. It would be spot on at the beginning of each second.
