QU5 stereo MIX only outputting on one side

I have installed a Qu5 in a church (Have done this many times) and we are outputting MIX12 as a stereo MIX for a livestream. It is all working great but any stereo input channel is only outputting on the left side.

Please note the following…

  1. When I push pink noise through MIX 12 it works perfectly and is level matched between the mix output and the live streaming computer.
  2. The stereo inputs are metering as left only on the MIX 12 output when PFL’d.

3. The stereo input channels are coming up in both left & right on the main mix.

4. All mono channels are coming up on both left and right on MIX 12 feeding the streaming computer.

Is anyone aware of any glitches?

You have separate pan controls for each mix.
Please check if the pan controls of the stereo inputs for your Mix 12 are accidentally turned to the left.

100% checked this. If I pan a mono channel, it follows in the mix 12 metering. If I pan the stereo channel, when panned left it responds correctly but when panned right the signal disappears.
Great suggestion, but no prize. :blush:

+1! Bug report

Depending on buss configuration mono/stereo and aux or group
Some busses will kot output on the left channel
Internal siggen will output on left and right, but all forms of input routed to the buss only pass audio to the right channel.

Helps as a temporary fix to change the order of your mono / stereo busses and aux or group type

Ah, so it’s a known bug?
But the OP describes it differently, namely that only stereo inputs are affected, and only the left side of the bus works, and the right side doesn’t.

SLightly different from what you are describing but similar. Left side only and no right, but fine for mono input sources.

A&H support have let me know that this is definitely a known bug and have it flagged for the next firmware update. Hopefully soon. This only seems to occur if you change the buss config after you have set everything up. If you set up the buss config pre setting everything else up, then it seems to work.
The problem we had is that the MIX 12 buss was changed a couple of weeks later.

Thanks for your feedback.
Now I actually wanted to recommend using ganging to combine two mono inputs into stereo until the bug is fixed, but the word “Ganging” only appears once in the user guide of your QU - probably because it was copied incorrectly from the SQ.
So, your QU doesn’t seem to have any ganging at all (yet), right?

And you’ve also surely already tried saving the state as a show and reloading it, but to no avail.?

Yes, we have tried all of these things.

The good news is we finally found a fix…

We changed the stereo aux back to a group and then back to an aux again and that fixed the issue. :man_shrugging:

Hmmnn.. I have similar issue. When turning AUX7 into Stereo, it only plays L channel. Panning to the right makes audio disappear. The “fix” aisle-6 describes seems not to work for me. I have latest firmware.

Does anyone have more insight in this issue?

In October, it was reported that A&H had confirmed the problem, and in November, a firmware update 1.1.1 was released – including fix ID-1379 – “Fixed mix channel routing issues after configuration changes.”
At least that sounds like it might have resolved the OP’s problem.

You mentioned you have version 1.1.1 installed.
Then the workaround from October shouldn’t actually be necessary anymore.
Perhaps you’re experiencing a completely different, possibly even trivial, issue.
Does it also only affect stereo inputs for you, as it does for the OP?

Thanks for your reply. Maybe it’s not possible what I want. Through the I/O setting, I only can choose Mix7L or 7R, no stereo configuration. See:

I can put the Rockboard HA-1 to stereo, so I thought, let’s make a stereo in-ear monitor mix (not balanced, I know).

You obviously haven’t assigned your Mix7 R to any (local) output.
Then, of course, no right signal is there.

Yes, I know. I wanted to put a stereo signal (mix 7 configured stereo) on local output 7 only. But I have to use output 7 (mix7L) + output 8 (mix7R) to achieve that. Then use a dedicated cable to supply it to the Rockboard HA-1.

That’s not possible.
These outputs are always single-channel balanced.
For any stereo input, you’ll need a suitable Y-adapter cable.

You could also take a look at the user guide.

Yup. Thank you so much!
