Bugs with v1.9?

[dickiefunkParticipant]

Hi,

I am using the QU-PAC and QU16 mixers and have had a couple of odd things happen with these mixers since the v1.9 update.
I had the QU-PAC on a gig last weekend and for some bizarre reason the 48v Phantom power would power my condenser vocal mics!? I tried different channels, leads and mics and none of this sorted the problem. I re-booted the mixer and everything worked perfectly!?
The QU16 is installed at a venue and one of the engineers had an odd thing happen. Basically the audio from a few channels kept cutting out!? He also did the usual troubleshooting of different mics, leads and channels but none of this solved the issue. He re-booted the mixer and everything worked perfectly!?

Has anyone else been having any issues since the v1.9 update?

My headphone out volume changed. It could be some setting I’m not thinking of, but I can’t figure it out.

For the entire year and a half I’ve owned the Qu-16, my headphone volume on the Phones out was set at 1:00. My headphones are Sennheiser HD 380 Pros. I loaded the 1.9 update and rebooted. Ever since that moment I’ve had to set the headphone volume at 9:00 because now 1:00 on the Phones out is insanely loud. The Alt out and main outs to my monitors are unaffected.

No intermittent audio problems or phantom power issues here, though.

Hi,

Since I installed v1.9 i got sound glitches. At first I thought they were only for USB-B streaming, but then realized that it was from incoming signal also.

If I got to the QU Control Panel and changed the streaming mode (eg. from ‘safe’ to ‘normal’) it would be ok for 2 or 3 minutes and then come back again.

My only solution was to get back to v1.8, but I really want this windows DAW control :/

Incoming over USB or through the preamps?

I’ve had stereo recording dropouts. (see next thread) I’m thinking of reverting to 1.82 to confirm.

@dickiefunk can you confirm if you’ve had this issue since the hard reset?

@veredasestudio sounds like this is a different issue. Have you checked the other forum threads? There may be a solution to a symptom similar to what you’re reporting in this thread: https://community.allen-heath.com/forums/topic/usb-b-streaming-audio-distortion-qu-24
Can you confirm if this is the case and if changing your default sound device in the OS to the onboard device but still using the Qu in your DAW prevents this?

@daleshirk I posted a comment in your original thread re this. Can you check and let us know?

Thanks.
Harry.

Hi Harry, I have looked into that thread, changed my gfx card (luckily I had a spare non-nvidia based), did this step you answered with and the issue continued. When not in DAW every single file i played started to glitch after a couple of seconds.

As soon as i downgraded my qu32 firmware things got back to normal. It’s quite clear to me that the issue is this update. Both incoming and streaming signal are now ok, but I really want DAW control for my qu32.

Hi Harry,

No I’ve not encountered any problems on either the QU-PAC or QU-16 since.

If you have a Reaper template setup in your iMac with channels muted to your Custom layer
and you disconect the USB DAW OUTPUT PORT return then you cannot unmute those channels in the custom layer of the desk.
I discovered this by way of using [Reaper] fader automation ITB [in the box] where you can turn off the DAW output port coming back into the QU so you can repeatedly adjust channel strip volumes in a mix down stage ITB [in-the-box]

Its hardly a fault but …. but it would be good if corrected 😐
its a way of getting around the “touch sensitve fader for automation requirements”

I had another interesting glitch with the QU-PAD app at the weekend using a QU16. Basically, the purple HPF curve kept jittering left to right on the screen on a few channels. It only lasted for a few minutes then didn’t happen anymore throughout the event!?

I’ve had an interesting issue recently but perhaps it has nothing to do with 1.9 although I never noticed it prior. It appears the the signal coming from main out R is not as strong as the signal going to Main out L. I changed speakers (powered) recently and it has happened with both. I was using Line 6 stage scape speakers L3t X 2 and L3s(subs) X2 when I first noticed this at a sound check at a gig. All 4 speakers were at the centre detent 12:00 position. I compensated by turning the R side up on the speakers until it sounded even. 2 months ago I decided to switch over to the new Bose F1 series tops and subs and during sound check this past Friday night I noticed the same thing. I compensated doing the same thing turned up the right side on the speakers.

Now perhaps there is some main out pan setting that I just haven’t found. This is my real hope because that would be an easy fix (provided that what it is set at now is favouring the left side). Prior to finding this thread I though maybe there is some sort of mechanical issue with the mixer and that it might need to be serviced. But now I am thinking that it may be some software glitch with this latest software update.

Any thoughts on this would be appreciated.

Which desk, that rings a bell…

[MarkPAmanParticipant]

From Qu-Contol, select the main out, and the output ballence is the first thing you see on the left.

Is that your hidden setting?

[neill00Participant]

I’m using qu pac, when I go to qu-control I don’t really see much there other than a blank set up to start from. Main out balance doesn’t seem to be one of the options in that section. It would be great to find a main out balance or pan setting just to see if it’s off a bit.

That said, I set up today for rehearsal and couldn’t really notice the issue. It could just be that it’s harder to detect in a smaller room with the speakers closer together. Or maybe it’s something that doesn’t happen on every boot up of the mixer, which would bring us back to maybe a 1.9 anomaly. I’m going to try to monitor this as closely as possible.

[MarkPAmanParticipant]

Sorry – I had just spent some time setting up QU-Control for a rather strange event I’ve got soon and had it on my brain!

What I meant, of course, was QU-Pad!
Just select the main L+R output and you should see the balance control.
