Audio thru XLR cable into Raspberry Pi

#1

Hello everyone!

My apologies in advance; this question doesn’t pertain directly to JUCE. I’m asking because this community likely has a huge expertise intersection with this problem.

I require getting output from a mixing desk (via an XLR cable, it seems) into a RaspberryPi.

I have some embedded-dev experience, but no experience with mixing desks or XLR cables.

Can anyone get me started here? Can I be guaranteed <5v output from the mixing desk? Should I even be using XLR?

I’ve found http://iqaudio.co.uk/hats/95-pi-dacproxlr.html – is this a sane candidate?

And most importantly: can anyone recommend an appropriate community for asking this question?

I don’t think what you linked will do what you want. I think that’s XLR out only.

The easiest option would be get a USB Audio interface with XLR inputs. Something like this: https://www.roland.com/ca/products/duo-capture_ex/

If you want about you can get something like this. It’s not XLR, but it’s still balanced inputs, so you can run XLR to 1/4 inch cables: http://www.audioinjector.net/rpi-ultra

The other option is https://www.hifiberry.com/shop/boards/hifiberry-dac-adc/
It’s 1/8 inch stereo in. You could connect with something like this: https://www.amazon.com/TISINO-Stereo-Breakout-Double-Cords/dp/B07K58L9MW

You’d lose the benefit of balanced audio signal. But line level, short run, balanced isn’t really required.

Anyway, I’d be interested in hearing a bit more about what you are trying to do. If you don’t want to say publicly, you can email me directly at roland@tracktion.com
