XLR Audio to SDI AES/EBU on ATEM Television Studio

[Doug Fish]

[Bob Zelin] “(Richard – you are right – you can just take the 75 ohm RCA output and feed the ATEM – great simple discovery !).”
Bob, Bob, Bob. Apparently you forgot about and did not return to this thread:

Your response in that thread probably sold a lot of Behringer SRC2496’s (including one to yours truly), as it was the first discussion of how to get sound into the ATEM TVS, and I think you gave a pretty comprehensive answer (although the XLR to BNC suggestion turned out to be needlessly complicated).

I hope that I in turn got a few people buying RCA to BNC (and hopefully other) cables from monoprice. Their quality/value ratio is off the charts.

Is there configuration of the TElevision Studio that needs to be done in software to have the unit receive the digital audio signal from the Behringer? I have the unit connected using a XLR to BNC Transformer adapter and I also tried putting a RCA enc on the BNC Cable to no avail. I am not seeing audio in the black magic software.

Are there specific setting on the Behringer that have to be made? Please advise?

Thanks!

According to Bob’s post above, you need an Impedance Transformer to go XLR to BNC (not just a regular barrel adapter). RCA to BNC does not require an impedance transformer- just a straight adapter works fine.

Settings for the Behringer A/D converter:

• Set the Left-side Source button to “Analog”
• Verify audio input on the level indicators and adjust with the gain knob.
• Set the Mode button to “A/D & D/A Conv”
• Set the Format button to AES/EBU

I’ve had success with Behringer DEQ 2496 Ultracurve pro which has XLR Left & Right Inputs and an AES /EBU stereo output and it also has an audio delay of 300ms.

I understand that 110 ohm cable is better than standard audio cable (75 ohm) so I’m awaiting delivery of 110 ohm XLR to BNC cable. In the meantime, I soldered up a short length of audio wire I had lying around and it sounds fine.

Incidentally, for my setup the DEQ 2496 audio delay appears to be 14 frames — more than the 300ms (10 frames at 30fps) audio delay built into the Behringer DEQ2496, so I’m borrowing a Rane audio delay to see if that will get it into sync. I’m running 2 Canon HM40s and a Canon XA10 – picture is excellent — image quality from all 3 cameras is very similar.

Ok finally got all this together. Thanks for all the help and guidance from everyone. Will post a video for everyone to see in a week or so.

Biggest over all challenges…
Connecting the ATEM via the router so I could use it on the network
Getting the HDMI signal over anything longer than about 25 feet… 1 run was about 40′, other 2were about 30′

DA STUFF…
Imac 3.4 i7 16gb ram
Samsung Sync master Ex2220 (second monitor to the MAC)
ATEM Black Magic
Viewsonic LED HDMI 1080p VS13814
1 Panasonic GH2
3 Gopros HD2
3 HDMI via cat5 connections (could not run HDMI over 50 Cables)
Behringer Ultra Match SRC 2496
Netgear Router WGR61
Yamaha mg 102c Mixing Console
Samson CT7 Lavalier Mic

RCA to BNC (cheap and works awesome)
Audio Source Power Amp with 2 polk audio speakers connected 2 sony bookshelf speakers also so I could fill the dance studio with sound.

Thank you to everyone for giving plenty of info on this toppic. I am in the same situation. The only part I am not sure about is the part where the audio goes out from the mixer and into the delayer? The mixer has right and left outs and the delayer has only one xlr in. What out on the mixer do I use to go into the delayer? Do I go from the mixer to the SRC2496 then to the delayer?

I am using 3 wireless mics going into my mixer, small mackie, and only want to buy one delayer like the behringer shark FBQ100 to use with the Behringer ULTRAMATCH PRO SRC2496

Hi.
I have some questions (sorry for bad english)

– About latency of Behringer: is it possible to control it (like drivers in windows\mac, when you can to change latency or buffer from 1 ms to bigger value) or it fixed (in your case 300ms)?

– Is it possible to use sound-card of you PC\Mac, when you make broadcast by Atem Television Studio? In broadcast\capture software specify audio input from your audio-card (external or even built-in card), connect to it your analog device (mic, or mixer console).. What problems with this method?

[Deepak Sahasrabudhe]

Yes the latency in the Behringer is variable.

In my setup, I use the USB 2.0 output of TVstudio to send H264 compressed video and audio to the computer where streaming software (MX Light) recognizes the signal and connects to a streaming platform. I don’t monitor audio at this point because audio and video is delayed so I don’t know if I could get audio output via system card, but I probably could. Another person monitors the live feed remotely and lets me know if there are any issues with signal by telephone… we have not had any issues with audio quality so far.

I understand that the audio could be tapped out from the HD-SDI or HDMI outputs, but I have not had any need to do that so far.

Hope this helps.

I am new to using the ATEM TV Studio and have been using external audio for the three of four events that we have covered. I wanted to know if I could forgo the behringer and just use a mixer with a simple aes/ebu converter such as https://www.bhphotovideo.com/c/product/407747-REG/neutrik_naditbnc_f_aes_ebu_impedance_transformer_.html

[Benjamin Doyle]

If your mixer has AES digital out, then yes- you just need the converter. The Behringer is necessary when using an analog audio workflow.
