Yesterday I had this weird issue where on qu-24 the Pafl bus did not work.
I expected the headphone amp would be broken, then I thought what if I route the Pafl to Alternative out: also no signal.
Then I fiddled around with the settings of the Pafl bus, I tried all combinations.
Still no sound on Pafl.
Then reboot:
No changes….
Then I did a factory reset (after backing up my show)
The Pafl Bus was working again!
Did anyone else had a same experience?
And did the problem showed up again?
Had this problem again the last days, this time with a reboot the audio on headphone PFL bus was there again.
what could this be??? I also wrote today about a alt out problem on our QU-PAC.
i need reliable equipment, is there something I should check? the only thing what both consoles have in common is a StageRack AR2412 and on the Network Side a wireless Router (with POE)
Hello @Kalle,
Since this has been solved with a Hard Reset, it is likely to be something operational (A setting or configuration).
Please send a message to Support@ allen-heath.com with all the details on both issues (The PAFL and the ALT OUT), kindly add a screenshot of your PAFL settings on the moment of the issue experienced, and we will be happy to look into this with you.
Thank you,
Rafael
Update:
The board was in a repair center.
And today it Fame back:
Before I sent it in I decided to test it and diagnose the problem.
Turns out: when the board is disconnected a longer time from a power source then: all local analog outputs (7 dsp chips?) do not work anymore.
The aes output is still working though.
D-snake outputs where working always, after rebooting the local outputs where there again…
My thoughts were going in the direction of power supply problems, but it turned out to be a little bit more expensive
Apparently there was an issue With the mainboard.
So I had this replaced, now everything is working like it should be…
For a 10 year old board this was quite an expensive repair. But it was worth it.
