jwill Posted December 1, 2023 Report Share Posted December 1, 2023 I have recently had an issue where timecode is sent up the L/R audio snake feed to the camera, and is (obviously) heard on return feed. I am a Sound Devices 833 user since 1-23 and prior to that an SD 633 user. I can get the same effect just plugging the lemo and return ends to the mixer and listening to return! Remote audio says they will take back the 2 snakes with this issue, Sound Devices had not seen/ heard of bleed issues... so i faxed out both snakes on 633 and 833, powered via battery and ac....same result! Anyone else amongst this august group have similar issues? Quote Link to comment Share on other sites More sharing options...
rich Posted December 1, 2023 Report Share Posted December 1, 2023 many many years ago, i made up some cables so that i could get a timecode feed from camera on my umbilical to my 788T. because i used the 442 spec of wiring for a 10 pin Hirose, i used pin 7 for the timecode signal. because i had, initially, used an SQN umbilical, which was made on the assumption of balanced audio returns, i had timecode bleed on the right return. i then bought some VanDamme 4 pair cable (and subsequently Mogami) , and wired it so that it still had the same pin outs as the 442 spec, but - and here is the important bit, the audio return (pin 5&7) were on a pair of cables, and the timecode was on a pair (6&8). this significantly reduced the timecode bleed on the return. i then modified my SQN umbilical by swapping pins 6 and 7 at both ends of the cable, which made that cable usable with a timecode return as well.

Lucas Posted December 2, 2023 Report Share Posted December 2, 2023 Have you tried switching the output level from mic to line? Quote Link to comment Share on other sites More sharing options...
jwill Posted December 2, 2023 Author Report Share Posted December 2, 2023 I always use line level outs. Quote Link to comment Share on other sites More sharing options...
PMC Posted December 2, 2023 Report Share Posted December 2, 2023 TC is like rust. It bleeds and grows. The only time I needed TC return from a source I used star cable (twisted pair with shield) on a seperate but taped-on cable. No bleed. Never tried it in a cable snake.
