suddenly make strong noise

[soundfancy]

Hello, I am qu16 user bin. I have a problem with q16 recently. The first symptom is that when you turn it on, the pan sometimes goes back and forth from side to side and doesn’t boot. At that time, if you turn it back on once or twice, it boots normally. The second one is a bit serious. During use, channels 1 to 16 suddenly make strong noise. It becomes normal when you turn it off and turn it back on, but it’s a bit like that again. I did it at the performance site, but it doesn’t happen when I test it in the office. What is the problem? The grounding of the power was also normal. The only thing that is a little suspicious is that the airbounce was connected to the same power source together, but I do have some doubts because I use the motor. I did the grounding properly, and I also used the Sergio multi-tab for the console power, is it related to the noise phenomenon? Or is it a breakdown of q16?

It is not possible to diagnose your issue remotely, so it’d be best to contact your local distributor and have your Qu fully checked over and serviced if required.

Thanks,

Maybe try a firmware reload…..and then test it many times before taking it to a show.

Thank you very much for your response. I checked to send q16 to Samasound, a distributor in Korea, but they said they didn’t have any abnormal symptoms. So they can’t fix it. It’s a relief that there’s no problem, but I think it’ll still be unstable to use. I’ll try to reinstall the firmware when I get q16 back. What are some common cases where these symptoms can occur?

And write down some additional symptoms that may be related.
First, the led in the middle of the st2-channel channel meter is not displayed, but the distributor says there is no hardware problem. This symptom has been quite old. Second, I don’t know if this is an error, but for example, if you call in scene 50 and turn it off, scene 50 is normally called, but when you press the scene button, it shows scene 0, so I always had to scroll through 50 times. It was a little slow. I was wondering if this was a failure or if it was supposed to be like this
