No Audio on Scarlet with rode videomic

[Greg Blakey]

Hi! Just wondering if anyone else is having issues with the audio input. It registers as the mini jack is live, but no sound is coming through. Is it just the rode videomic?

Regards
Greg

Coming through? What do you mean? After ingest, is there no audio on the file or are you trying to monitor in camera? You do know that there currently is no audio monitoring in camera except for meters, right?

You need the proper cables or use the A-Box adapter. More info here:

No sound in the meters. Nor on the files.

Thanks for that link Bob, It can be hard to sift through all the posts

I will see what the wiring is on that mic

I use the A-box with that mic with no issues.

My mic is straight to mini jack. Thats what is confusing me, i would have thought it was a simple option

Im not sure how the a box will help

is yours the same?

 

[Bob Gundu]

The A- box essentially has the proper cabling required for Epic/scarlet. You have the option to spend $200 or $10 bucks on the HOSA.

Oh ok, but does that take mini jack in? As the mic has a fixed mini jack plug, No XLR

Thanks for your help

Great link Bob, only wish I saw this two days ago. Just bought these in a BH order and yup, mine are the M version ahah. Bummer, oh well I will check the local music shop, they must have em.

DVshop has them.

This is not true. Audio can be monitored live through the headphone jack. Audio is not currently supported for playback.

I use the VXLR:

This is the pinout for the VXLR, by the way

Tip and ring are bridged and go to XLR pin 2, sleeve goes to bridged XLR pins 1 and 3.

On Scarlet the jack is a remapped blanced audio input, Tip is IN+, ring is IN- and sleeve is ground.

From the VXLR pinout, the Videomic will give you OUT+ on both the tip and ring and ground on the sleeve. Therefore, when you plug the Videomic into Scarlet you apply an identical signal on IN+ and IN-, they will cancel out at the differential amplifier and you won't get a signal. I believe that the UNBALANCED mode allows you to use a mic like this but I'm not sure if it ignores the ring and just uses IN+ and Ground or if it uses the ring somehow. Also, I've heard mixed reports, it might not be enabled in the current firmware.

You could make a female to male 1/8"/3.5mm/minijack cable which shorts ring and sleeve on the camera side and maps the sleeve on the mic side to the shorted ring and sleeve on the camera side and the tips connected as normal. Leave the ring unconnected or connect it to the tip on the mic side, be careful not to short this to the sleeve, the mic won't enjoy that. The camera, then, would be subtracting ground (0) from IN+ and wouldn't kill your signal. It's doing the same thing the VXLR without all the extra expense and bulk of full size XLR cables.

Isn't that mic a stereo mic?

RODE make a stereo version but the original VIDEOMIC is mono, I believe.

Solved it! a mini jack stereo to min jack mono plug made it work for anyone else that has this problem at $1.95

Cheers!

I have the A-box from wooden camera and I had problem to get any sound.
I used only one rode ntg2 mic but I did connect both of the A-box cables to the Scarlet. I got it to work first after only connecting one of the A-box cables to Scarlet (the one with the mic connected). As soon I plug in the other one the mic "disappear". Is this normal?

Just keep an eye on new builds before you upgrade your camera, in case they re-enable the phantom power...

Probably one of the reasons that it was disabled in the first place... They know when mics are unplugged, I think it should automatically disable phantom whenever a mic is unplugged and have the user explicitly re-enable it with a warning dialogue.

Pretty sure they decided not to have phantom power at all in the Epic/Scarlet.
