StudioLive 32R - Channels Set to USB Stop Working

Hi Everyone,

Hoping someone can help me with this. I use a 32R for ear mixes for live shows. We run backing tracks (three channels) via USB from a MacBook using QLab. I set three of my channels on the 32R to USB then set QLab to route the tracks to those channels. This all works just fine...usually. Sometimes the USB channels will all of a sudden stop "receiving" signal. I can see QLab running but the signals are not hitting the 32R. And the only thing that has happened from when it was working to when it stops working is that the rig just sat for half hour to a couple hours (between soundcheck and the show). Pretty sure it's the 32R since the only thing that fixes the issue is power cycling it.

Anyone else dealing with this and possibly have a solution? I have the feeling it has to do with dirty/unstable power. I have this problem and other weird sound issues mostly when the stage is getting power from a generator. But last night it happened at a nice indoor venue with standard power.

I'm pretty sure I'm on the most recent firmware, if not I'm on the one right before that. And I'm on a 2022 MacBook Pro with the most recent version of QLab.

Fist I would like to mention that its a good idea to use high quality USB cables...  But I doubt that is the source of your problem.

I have a similar problem with my 64S after I updated to the most recent Universal Control ( and 64S Firmware (  I would first encounter intermittent signal then it would go out completely.  Then the 64S would stop responding to the computer.  I opened a ticket with Presonus and the resolution was to switch the 64S to Compatibility Mode.  I switched it back to 64 Channel Mode and it continued to work.  It fixed the problem initially but days after, it lost connection again.  I switched modes again and it started to work again.

This is very frustrating.  It appears that the drivers for  Studiolive Series III is very unstable.  The most stable firmware I've experienced is Firmware V2.4 along with Universal Control V3.4.  I'll give this current version a couple more weeks of experimentation but I'm afraid I may end up rolling  back to the older more stable version.

Presonus, if you're listening, please give us stable USB drivers for our mixers.

zberto, I hope this helps.  What version of firmware and Universal Control are you running?
