It appears Allen & Heath is aware of this and they are – to their credit – working on a solution for me. Current theory seems to be that some ab168s revert to an older version of the firmware on some connections to some Qu series mixers some of the time. Connecting to a GLD re-updates the firmware and problem solved. I suspect there will eventually be a newer firmware version that prevents the reversal. Not sure how that will get applied at sites that don’t have GLDs, but if the GLD can update the firmware, there have to be other means as well. Hang in there and contact your sales rep or the company if you experience this. They want to get this solved as well. Fortunately, it seems to be rare.

I have a theory folks. Ever plug/unplug the ethernet cable while the ab168 is on? Makes noises, acts funny,etc. I have a feeling there is no protection circuit on the ethernet card – which is unusual any time after 1996, but possible. I plan to ONLY connect the unit while the unit is powered off as a precaution. My dealer graciously got me a replacement immediately, so I, at least, am back in business.

Argh, just happened to me on my 3rd time out with my AB168+Qu-24. Swapped out Ethernet cable, rebooted everything. Brought everything home and reset the firmware, as everyone above, but to no avail. Used the
ab168 for outputs, which worked fine, but had to create a 16 line snake with lots of connected XLR cables. Had exactly *1* left in the hamper when all connected. Fortunately got to the gig 4 hours early or this would have been really bad. I have a couple weeks before the next show when the ab168 is essential, but really never want to have this happen again. I use the AB168 plugged into a Furman, so it not have seen any spikes at any time. Odd that it doesn’t have an on/off switch though, as turning things on/off via plugging is often a bit dicey. And, of more concern, is the replacement board also likely to fail at some point in the future or is this now a fixed problem? Never want to have to do that again.

Thanks DavidCo:

It was not explicit anywhere so I just wanted to verify, which you’ve done.

Thanks!

Thanks DavidCo, but my enquiry is not directly answered there. Is there a scenario where the 8 ports on the AR84 do work as ports 17-24 on the Qu-24 or Qu-32? This is covered for the Qu-16 (that is they are ST1-3), but not for larger frames – or at least not that I can find.

The PDF, btw, does not show the AB168+AR84 configuration, so even though it’s apparent that it does work, it’s sort of missing on the “quick start guide” 🙂

Somewhere along the line it appears that the possibility of using an ab168 and ar84 with a Qu-24 has been missed or at least I’m missing something 🙂 With the 16 the additional inputs become ST1-3. Is that the case on the Qu-24 as well or would they actually fill out inputs 17-24? (a desirable outcome in my book).

Thanks!

Also interested in this step by step as a new qu-24 owner. First pass didn’t work with lots of weird lights on the console and nothing controlled on screen.

Set DAW control app for 1/2 and au-24 for send/receive. In S1V2, did the same (au-24 for send/receive)
to no avail).

Any specific tips appreciated for both the DAW software and S1V2 MIDI device set up.
