Best / simplest audio solution into ATEM Television Studio?
on Sep 26, 2012 at 6:14:04 pm

Just got TV Studio for conference / meeting webcasting, Using XDCAM EX1 cameras - SDI into Atem for video.

We have 2 Sennheiser K66 boom mics. Am thinking simplest audio solution using our kit is to plug mics into another camera (JVC GYHM100) that has HDMI out, and send that to HDMI in on ATEM.If we do that - I assume the sound will be in sync - correct?

Another solution - we bought Yamaha mixer and Behringer SRC2496 as suggested by BlackMagic.

But how does the audio get from Behringer's analog XLR twin outputs to Atem's AES EBU input?

Is this more complicated solution advantageous, given our events' audio levels are very uniform?

Answering myself - I just discovered that SDi outputs from the EX1 cameras also carry the audio from the cameras - I had no idea...

Also, if you decide to use the Behringer SRC2496, use the RCA digital output into the AES input of the ATEM. Basically, a cable with a RCA adapter on one end, and a BNC adapter on the other end.

EDIT:
I take that back. It looks like on the Behringer that AES is output via the XLR output. So you would need a cable with XLR on one end, and BNC on the other.

The TVS has only digital audio input. I don't know that it does anything with the audio data coming in on an SDI or HDMI video input.

Furthermore, "sync" implies that you are delaying the audio signal so that it matches the video delay and everything is synchronized at the output of the switcher. None of your proposed solutions provides the necessary audio delay.

OTOH, the Behringer Ultracurve Pro DEQ2496 is reputed to provide both analog to digital conversion AND audio signal delay.

Thanks Richard, in my brief testing today the SDI audio from my cameras does appear to carry through the ATEM and looked in sync. But testing wasn't very scientific as other issues loomed larger and diverted attention.

Am sending the ATEM output to Adobe Flash Live Media Encoder to stream for webcasting, but experienced loss of preview in Adobe FLME, streaming stoppage / restarts, and terrible encode results from the ATEM (grey stripes on switcher cuts). So am off to ATEM users forum for advice.

Yes, with a firmware update a month or so ago, SDI and HDMI now passes audio on the inputs of all ATEMs. If it's coming over SDI or HDMI, it should be in sync.

Cheers - audio is looking good, except that as I am sending it with video to Adobe Flash Media Live Encoder for streaming, I can't see any way to monitor the audio that's being recorded and output, aurally.

Go HDMI program out of the ATEM into a monitor with speakers, that'll have audio. You'll just have to trust that audio is being streamed as well. To test it, use another computer to download the stream.

Ta, I also have a h4n recorder - can Hdmi audio out of Atem be converted to xlr in to h4n for monitoring?

Usually would monitor the webcast as audience sees it - but here we will have very limited bandwidth for streaming so don't want to rob ourselves by monitoring.

Easiest way is to use the SDI Program output, and then go into a de-embedder (which splits the video and audio).

I still think the cheapest way is to use HDMI, either going into a HDMI monitor with speakers, or if you just want audio, an audio receiver with HDMI inputs. You could always add a monitor for video later going that route.

Thinks again Mike. Can you suggest a De-embedder? Am not a sound chap. Do have Behringer SRC2946 that I bought with Yamaha mixer before i knew Atem didn't need them. Otherwise yes,, buy HDMI monitor

I'll have to get with our engineer for a good de-embedder, but, since you have the Yamaha and Behringer, you already have all the equipment you need.

Connect the mics to the Yamaha, Yamaha to the Behringer, Behringer XLR to the AES input of the TVS. If you have audio delay, the Behringer can fixed that.

Also, now you can monitor audio via the Behringers other outputs, such as S/PDIF out to an audio receiver.

This is the correct way for audio, as now you can control the mix properly and quickly (via the Yamaha mixer). Plus, you can add more audio sources, depending upon how many channels your mixer has. In our studio, that's exactly how we do it (and we too have a Yamaha mixer).

EDIT:
I need to correct a couple of things:

1. That Behringer model does not do audio delay, the DEQ2496 does, but you may not have a problem with audio delay.

2. To get audio from the Behringer to the TVS, use the RCA digital output from the Behringer (with a RCA to BNC cable). This way, you don't need an impedance matcher, as the Behringer's output is 75ohms, the same as the TVS's AES input.

3. The Behringer has a headphone output to monitor audio.

Hope this helps.

We use wirecast to encode our streams, you can monitor the sound on it and it also has an audio delay feature - up to 1s. Touch wood we have never had any issues with it and the ATEM TVS. We are using Blackmagic Intensity Extreme's to get the video in but have used intensity pro on Windows machines too with no problems.

We used Flash Media Encoder for a while but found it frustrating and wirecast has been well worth the outlay.

We pump the sound in via the jacks on our HDMI-SDI converters but using the mic inputs on your cameras would do the same job. We have also used the inputs on the breakout cable with the extremes but doing it this way means you cannot record sound directly from the TVS via the USB connection.

Hi,
sorry .. I am buying now the ATEM Television Studio and I am a bit confused on what could be my best setup. My goal is a small portable setup for small jobs. I understand that later firmware updates get audio from HDMI and HD-SDi streams. I immagine it is possible to choose one of the audio streams as a master so you switch cameras but keep the same audio. If I go from the line mixer into the nearest camera's XLR inputs I will be gettin master audio on that camera... Still I could have delay though because we are not talking of the camera mic audio.. or no?
Also I am interested in WIRECAST.. how does it work with ATEM.. can you use that software instead of ATEM controller software or is it just for recording video? I am new to this kind of configuratiions so I don't understand... I can use ATEM with other softwares? I can control effects, transitions etc.. on wire cast? What about this 1s delay in wire cast.. is it good?

If wirecast works fine and I can put audio into one camera to get it back together with the video.. I will not need Behringer (neither SCR2496 or DEQ2496.. confirmed?). So basically I just need the ATEM and that's it ?

Hi Marcello,

We have used the set up you describe with no delay issues. Wirecast has a delay option for sound anyway so it can be fixed if there is an issue.

Mostly we put the feed into one of the blackmagic mini converters we use for sending hdmi camera feeds via sdi.

If we are only streaming and not recording then we put the sound directly into the Blackmagic Intensity Extreme that we use to capture the video from the TVS.

Regards,

Mike

Oh and wirecast can be used for switching if you have more than one video feed into your computer but it will not control the TVS. To be honest it is a bit clunky anyway, you are much better using the TVS.

Sometimes we will have a second camera connected directly to the computer if we want picture in picture which wirecast has but the TVS does not.

Yes.. this is what i don't entirely get....
ATEM is basically a 6 input device so in theory I could use Wirecast for "effects" (PIP and so) and for sound delay... but you're telling me it's chunky.. so in the end.. regarding effects I just have to go with ATEM and regarding delay (if any) I'll have to get an hardware like Behringer DEQ2496 i guess.
An inbetween direct camera for PIP is not really a solution I think... just complicates all because you could do PIP only with that camera and you need the two softwares on at the same time, etc...

Hi Mike Squires,

Say hi from Thailand, i have my own set up same as your advice. but i do need some more info that can i connect Behringer ULTRAMATCH PRO SRC2496 to TVs ? and How? it could be RCA to AES cable or XLR to AES?

Thanks and Best Regards

Hi Mike squires,


Say Hi again, i have bought worldwide for Sescom --> http://www.bhphotovideo.com/bnh/controller/home?O=&sku=748792&is=REG&A=deta... as your recommended but, a curious thing is i have got this : https://www.dropbox.com/s/79dempwlawbhfjv/photo%201%20%281%29.JPG and https://www.dropbox.com/s/9o8vpjcdn2tsm7u/photo%202%20%281%29.JPG

I just want to know,why it has male xlr which not the same as your recommended?
Is that mean i do need both female xlr cable? to connect from behringer to Sescom,coz XRL digital output of Behringer has male xlr.

https://www.dropbox.com/s/79dempwlawbhfjv/photo%201%20%281%29.JPG
