Big problem with Scarlet Audio

[Timur Civan]

Since most of the time im shooting sync sound with no audio line to camera, i hadnt noticed this before.

Shooting standups tomorrow, where the client needs Stills from the video, (what better camera?!) im testing the audio, but its HORRID. There is almost no sound and its making a clicking noise.

Im uploading an R3D clip for you all to test and see what the problem is. I'm using a Sennheiser wireless with 1/8mini jack going into the Scarlet. shooting 3k@ 12:1, Camera audio in Balanced mode, at almost 40dB on camera, and the Sennheiser Mic @ +00 sensitivity(the highest it goes) and the AF out on the reciever at +12 The highest it goes....

I cant seem to get a level on the camera. This is disturbing.

Are they all like this? I'm going to test unbalanced mode perhaps that will help......

will post the link to the R3D when its done uploading in about 40 min.

Immediate thoughts on situation? am i doing something wrong?

AFAIK the camera is unbalanced only at the moment. The 'balanced' option does not really work I think.

So, tape over the ring contact on the input plug or find a way to convert the balanced output of the radio mic receiver to an unbalanced signal.

Thanks Cail, will try it.

I found all sorts of issues initially getting my audio set up properly and what it came to was the 3.5 mini jacks on the red are wired differently than most. You can find people explains TRS blah blah. But the short of it is that you should get a x A BOX and keep it with the cam. Will allow you to use industry standard XLR and your G2 kit wil work great, I use them a ton. I was getting pops, clicks, and low levels trying to find 3.5 to 3.5 that would work. Now with that said, you are in a bind given your shoot is today. I would go to an audio store and buy a 3.5 to XLR adaptor, be sure it's a single output (they make ones that split from a single 3.5 to two pig tails). And connect your kit via xlr. It's a cheap purchase and will get you out the bind. It's still may not be wired perfectly for phantom power etc, but I have found most to work for basic sound it. Set the cam to unbalanced and you should get through your shoot today. I am sure someone will come now and explain why what I said is all wrong, but i have been exactly where you are, and it got me out the bind.

This underlined advice is wrong. "Mono" doesn't really mean Mono for a 1/8 TRS connection. Read this post in the Audio section: These Cables Work. (And why) The information there will apply to any adapter cable.

Balanced audio is enabled in build 2.0.5.

You need a proper ring tip sleeve input to the mini jack. You can either use RED's cable or I can't recommend highly enough Woodens Camera's A-Box

[Randall Brown]

Yea poor word choice, i meant to be sure it had a single XLR output, vs 2 pigtails. Updated that post, and your linked to post rocks anyway. I knew smarter folks would come to aid.

That's the biggest problem with the choice of 1/8" TRS as the audio in connector on Epic/Scarlet. It is so easy to get confused about the cable should be. It is a mono input, but if you buy a cable that says mono on the package it is more likely than not to be wired wrong. With XLRs (or mini XLRs) there is balanced and unbalanced and everything else is a weird special case. With 1/8" TRS, balanced mono is a weird special case.

With all due respect I'd disagree with that, but if there is uncertainly how to wire the TRS, there is now the option of purchasing an XLR to TRS audio adaptor cable from RED.
