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.

Thanks!
