  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Clicking noise – only when recording, not monitoring

I'm having some problems recording audio on the Scarlet.
When I have my Sony wireless mic plugged into the body, it sounds great when monitoring. But as soon as I press record, the camera will monitor and record a fast clicking noise along with the regular audio. Its not a power hum, but it has sort of the same clicking frequency.

I also have a sennheiser wired microphone plugged in with no noise problem at all when recording.

I've tried switching the jack-xlr cables and tried switching the ports, but with no luck.

Has anyone tried this before?

(Also, I usually record with my H4n, but I'd just like it to work with the body in case I should ever need it)
 
Casper,
It seems that this happens only with Sony wireless.
i have the same issue.
i event sent my camera to Red for few days.
came back and same problem.
i finally gave up on the sony and started to use me sennheiser shotgun with phantom power and got beautiful sound.
 
This is the pl mount thing... change firmware and or put a small tape over the connectors on the mount.. so it becomes a "dead mount" it's the electronics of the mount that trys to connect to your non electronic lenses. A listed bug on some of the previous firmwares. the latest one should have it addressed I think, as Bob mention above.
 
I have the same issue on my epic... I have a service tag set up to send it in to Red but i have not had a work window to allow me... The epic keeps me busy!! Luckilly, we only use it to recors scratch, and the clicking is fine for that

I have the latest build and it hasn't fixed it at all. I wonder what it could be.

Did you try record with no lens and no lens cap? If it's clicking then it's not the mount...

If the clicking stops, look into isolating the connectors of the Ti PL mount...
 
Glad to see I'm not alone :-)
I have a Canon mount, but that has electronics in as well - so I guess it might be the same problem?
I just think it's curious that it only happens when the camera is recording

I'll try without a lens on and see if that helps

Thanks for all your suggestions
 
I was having big problems with this at a shoot today (running latest firmware and using an Azden wireless mic) and stumbled upon this and another thread discussing it... with no apparent solution. Anyhow, I was able to get rid of it by simply choosing the Balanced / 48 Volt option under the "Audio Channels" menu. Hope that helps, incase anyone is still having issues with this.
 
I too am having this issue with sony wireless mic. I have the latest firmware on a scarlet. Any new ideas on why it continues?
 
I have attenuated the issue by using a balanced input even if my Sony system is not. I also think that as I am using stereo mini jack cables I wonder if this is not causing noise. I now have a high pitched hum that that correlates to the fan.

The high pitched electrical fan interference is because your stereo mini jack unbalanced cables are incorrectly wired for the Epic/Scarlet MONO BALANCED audio inputs! They are non-standard balanced inputs, so any mini-jack cable adapters you use have to be wired accordingly. Either buy the Red manufactured adapter cables or rewire your own - see the Operation Manual PDF for the pin-outs of the audio connectors.
