Qu-Pad shows no signal

[TalentCraftParticipant]

I had this working where I could see and hear signal. I’m testing channel 16 with a condenser. 48v is red. 30 dB gain and nada. I am still learning the Qu-Pad; only recently got it, but I’ve been through so much of its aspects that I am mystified why there’s no signal going in , when I clearly had it a few hours ago.

[BRSParticipant]

Could you have accidentally hit the “on” button on the channel, thus turning it off?

[TalentCraftParticipant]

Thanks BRS. No, I checked that. Even if I hadn’t, wouldn’t the channel react to signal coming in? …and for the record, I swapped out the mic, then the cable, so to rule those out…

[SteffenRParticipant]

did you switched the input to USB?

[TalentCraftParticipant]

thanks Steffen R. Ch.16 input source is “Local” (red) and USB B (blue). My understanding is that “local” identifies my Qu-SB XLR in on that channel and “USB B” …<-the out to my iMac?

Did you try another channel?
Try a dynamic mic.
If you PFL the channel do you get anything in the headphones?
Is that channel assigned to a DCA group and or to an audio group that is turned down?

Pre amp source menu to local (red) is correct.
The USB (blue) is to playback audio tracks bringing them in through
the USB B jack.

[TalentCraftParticipant]

Hi Mikie, thanks. Yes, I tried ch.14 also, plus swapped in a dynamic, to no avail. No surprise that PFL (assuming that is what PAFL is in this land) yields no sound in headphones, and no lights in Qu-Pad.
Thanks for clarifying the USB B; I was going to submit a seperate thread on this but, I’ll jot it here: I also lost my ability to playback audio from Logic. I was using ch.31-32, assigned it out in Logic prefs, see Logic’s stereo out lighting with playback, but zilch signal through Qu-Pad, when I had that hours ago as well.

On the pre amp screen do you see any meter level?

And to double check, your plugging directly into the back of the QU SB?

Maybe do a full mixer re-set, do you have any scenes saved, if you do a reset
you will want to copy scenes that you want to keep off to a USB stick.

[TalentCraftParticipant]

Hi Mike. Thanks, that’s an excellent question, as I am not clear what the pre-amp screen is; I’m aware of how to navigate each channel’s processing, but in that area, pre-amp is not apparent.

Hi Mike. Thanks, that’s an excellent question, as I am not clear what the pre-amp screen is; I’m aware of how to navigate each channel’s processing, but in that area, pre-amp is not apparent.

The pre amp screen/menu is where you adjust the input gain and select the input source.

Do you by chance have the channel insert turned on? That’s in the pre amp menu, for the sake of testing keep it turned off.

[TalentCraftParticipant]

Yes, I thought that’s the pre-amp, just isn’t labelled as “pre-amp”, so I wasn’t sure if I had elsewhere to search.
Insert is gray; toggle’s on “FX”
thanks

Is it possible your iPad isn’t connected ? Or maybe tou accidentally turned on the gate which is too tight ?

Good luck !

Is it possible your iPad isn’t connected ?

Along those same lines any chance your in the demo mode on the APP?

If you go into to the set up menu, audio tab, signal generator can you send
pink noise to any of the outputs, do you see that on the output meters, can you
PAFL the output master and hear that in the headphones?

Have you tried a firmware reload and or a full hard reset?

[TalentCraftParticipant]

Thanks, Giga, but my iPad is connected via WiFi router and CAT5 to the Qu-16 Network. I also do not witness any disconnection.

[TalentCraftParticipant]

Thank you Mike C., but my iPad is connected, plus to clear, upon further testing I discover that leaving the studio overnight “heals” everything back to functional …until… a static “pop” kills -either- the sound and its corresponding lights that are active in Qu-Pad -or- only the sound: perhaps the first time that this happened, Qu-Pad lights will still actively reacting.
It’s as if the Qu-SB becomes to hot after several minutes, (it’s not) then mutes itself after an electrical “pop”.
I hope to hear back from USA Tech Support tomorrow. This will not do.
Thanks , again!
