Question / Help Allen & Heath QU-16/24 Digital Mixer --> OBS


New Member

New user to OBS, but not technology or basic sound engineering.

Using a multichannel mixer Allen & Heath QU-16, connecting a direct USB connection to a Windows 10 Pro Laptop. Device is recognized as "QU-16 IN", and an audio signal is detected however I'm having a hard time getting the audio into OBS. I've made the input hot to ensure a strong signal but can't seem to see a workaround. Are there any solutions, plugin's etc that may help to get this to work?



Latest firmware / software installed?
If OBS sees it as "QU-16 IN" it's detected OK most likely. If that's the status then great.
What's status of Post pre amp and Direct out? Do some testing on that. It's hopefully just a matter of locking in the right settings for it to work with OBS unless its simply isnt supported.

This is probably not an OBS issue.

Thanks for the reply's gentlemen.
All device firmware and drivers are installed. Laptop recognizes "QU-16-IN"... I can see amplitude input in the device config but, OBS does not show any input at all.

what kind of problems occur without the plugin? I noticed issues and now trying to determine if this was the cause.
As I learn more, I guess ASIO plug-in is only for Windows and I am on Mac.

regarding my issue of noise in stream from QU....

On QU I/o settings, you need to route your audio to USB channels and 1 & 2, so it can be seen by OBS. Same is true if using USB adapter to get basic audio into iPad.

You beat me to it Skip! I was trying to figure that out for a couple of days now and that thought hit me. Now, OBS recognizes the main output from my Qu16 USB-B to MacBook connection. Here's the screen from my Qu16:

I just went through this as well: QU-16 and a Win 10 machine. In my case I needed to install a Win 10 driver (from A&H's site) as well as the OBS-Asio plug-in to make it work. It looks like all 24 channels are available that way, so you could leave the QU-16's channel assignment in default, and just select 17 and 18 in OBS instead of 1 and 2, although since I had already changed the console, I left it alone.
