  • 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 :)

build 15 - audio

That's been my worst fear from the beginning. I for sure will be delaying my purchase until all audio issues are resolved, even though my number comes up (likely) in May.
Red speaking, everything will run smooth for that date (that`s the message i`m sending to the universe)

I`m getting the same hiss. I`m using a 416T (with a 48 converter). With the same set i got no issues on the Hvx
 
did you try to set to line?
If your mic has pre-amp and you are blasting at line level and camera is on mic instead of line?

check with line and then with mic setup on the camera.

Was the problem confirmed by RED?

nope. my mic doesnt have a battery.

i'm gonna test it out with another mic... and see if it works.

i kinda thought it was just a problem with my red so why would they confirm it since they mentioned that all these are resolved with the new cable and the new build... apprently it isnt because there are many who are having the same problem.

Self-Powered mic.. No Hiss

Self-Powered mic.. No Hiss

I just tried a self-powered mic (thank you Bassam). it works when i have it powered by the mic's battery... i get no hiss.

Hear it: http://www.bastaky.com/micpower.wav

Though when i turn off the mic's power... and turn the RED phantom power on... i get hiss.

Hear it: http://www.bastaky.com/48v.wav

Conclusion: it could be 1 of two things, or even both causing this anomaly.

i. Audio on build 15 is still a work in progress.
AND/OR
ii. something's wrong with my RED mini-xlr to XLR cable.

Akube-What self-powered mic did you use? We are thinking of replacing our mic, or getting a pre-amp with 48v built in for audio.

Thanks,
Philip
 
I have seen post informing that you should dissable all inputs that are not used, including 48V on it.

Phantom power withouth the load will produce the hiss.
Also not enough load on 48V will produce the hiss. (probably)
 
i used some sennheiser neck mic... i don't know the model number as it isn't mine.

i'd rec. getting an external power source. khmuse rec. me an AKG B18E or a Crown PH-1A.. i'll be ordering one of those tomorrow.

i read it long ago... the only extra valuable info there was that some phones work better and some phones suck in use with red.

and i aint gonna buy each and every mic on the planet to figure out which mics work with my camera and which ones don't. i expect my camera, like the rest of the folks here to be compatible with most xlr mics because those mics have worked with all the cameras they've used on before.

i'm pretty sure this will be resolved soon as audio is 70% of what you see.
hence again... build 15 audio is still a wip (work in progress), or the cable i got has some issue.

Put 600 ohm resistor accross the 48V pahntom and dissable the unused INPUTS including phantom power there.

how will this fix the hiss?
 
the audio finally worked for me.

I got an AKG B 18 (external phantom power supplier...) it works.

I am also having a problem with the audio in Build 15. There is a constant hiss only on quicktime playbacks. Reviewing the file on the camera through headphones did not have the same result. We shot on Thursday 3/27 using a Sound Design 302 mixer set as line out mixer/line in camera, with both a Sennheiser MKH 60 and Sanken CLS11 with the mixer providing phantom power and was still getting the hiss. We tried using the RED mini XLR cable and a custom made two channel mini XLR cable with the same results. After a few tests, we changed the mixer to mic out and the camera to mic in and still received hiss in playback. I dropped one of the files into FCP and after rendering the file was able to fix the audio problem. Unfortunately, the editors for the project have 100GB of footage and with upload and rendering times being quite lengthy it could take 10 hours before the files can be reviewed properly. Should we revert back to build 14? We had done some test runs with it and had no audio difficulties.
 
Audio fix?

Audio fix?

We disabled 48v on all channels one more time and new tests seem clean. We had disabled it prior, but it did not save the setting. Will be shooting again on Wednesday. Will post again if problems reoccur.
