Does the ESG3 have sync input on back?

I currently have a Cadet system and use the Cadet Video Input sometimes. I’m wondering if it’d be possible to use the Cadet Video Input with a ESG3 system. If it has a sync input, I imagine either it’ll sync to the video input, or the input video will need to be run through a sync stripper and then feed just the sync signal to the ESG3 sync input. Is that possible?

You should be able to use Cadet III with ESG-3. You would just plug whatever your external video source is into the rear RCA sync input of ESG-3 (it has RCA sync I/O) and your system would be genlocked to that external video source. Then take ESG-3’s rear sync output and loop it back into Cadet III’s top RCA input and then patch Luma wherever you need. You may need some passthrough RCA connectors to make these connections or leave a gap between modules to route cables through.

Also possible to put your external video source into Cadet III’s top RCA input first, then put its bottom RCA output into the rear RCA sync input of ESG-3. Should give you the same results in theory.

Cool. Thanks. That’s what I was hoping. I was pretty sure the ESG3 had sync on the back, but when I went looking for hard info about it today, I couldn’t find where I had gotten that idea.

Id love to know if you tested this out or if you could post your results!

I think this is the route you want to go. ESG3 has sync input, but no passthru of the input signal – the output signal is the sync generated by ESG3 (which should be locked to the phase of the input sync, but not carrying it’s video information.)

I hadn’t tried it yet but just quickly connected a few things to try it… and it worked great! I did as rempesm and lars recommended. A quick little self portrait as proof:

Sync: Camera → Cadet 3 → ESG3
Video: Camera → Cadet 3 → Staircase → ESG3

I wonder if it would be OK to always leave the Cadet 3’s RCA output hooked up to the ESG3’s sync input? Or should I disconnect it when not dealing with video input, for better <something>? The Cadet 3’s RCA output is buffered, so I when there’s no video input to Cadet 3 that the RCA output is just putting out a ~0V signal. Is that right? And would that signal degrade the performance of the ESG3 in some way?

I can’t think of a reason that would cause a problem. ESG3 is continuously sampling that sync input to detect activity, so if there’s no signal present, it will be operating on it’s own timing with business as usual.

Thank you for posting the picture! I have a few beginner questions about the signal path for you if thats alright.

So u have the camera output into the rca input of the cadet 3
Then the rca output of cadet 3 into the rear rca input of the ESG3

This is just the sync path right?
Is see you posted under ur picture two signal paths 1 for sync and 1 for video
How does this work.
In the sync path is the camera signal going into the cadet 3 the camera genlock?
Also In the video path how do you have your cadet 3 patched to the staircase, the cadet only has one RCA output right? Or do you have two cadet 3s? One for the sync and one for the video.
Thank you for your time and reponse any help would be apreciated

You would be using the Luma output of Cadet 3 to send it to Staircase or any other module you want to patch the video to.

Holy cow that makes alot of sense haha thank u

Yeah, @Vdot is right. The Cadet 3 is a composite-to-luma converter, and the luma output of the Cadet 3 is what you’d use with your LZX gear as a video (or modulation!) signal, and the composite video output of the Cadet 3 is just used for sync.

More detailed patch notes: In the case of my example picture, I’m feeding the luma output from Cadet 3 to the source input on the Staircase (which is like the red input on a Stairs module), and then using two of the /1 and the /2 outputs of the Staircase to feed the red and green inputs respectively on my ESG3 (and since blue is unpatched, the green signal is normaled to the blue input). A simple-to-patch colorization method (since luma has no inherent color).
