That is a strange error that I can't explain easily. Did you disconnect all the inputs to verify it's the UFX? Service in the US is done by Synthax US, just give them a call (see website, www.synthax.com/) or mail Jeff here in the forum.

Poor guy.  I watched your video and felt really sad for you.  I would be so upset if this were happening with me, I really hope you can get it fixed properly and not costing you too much.

Best of luck.

Hello RME,

It looks I'm experiencing similar issue. Since March this year very loud crackles started to appear sporadically. I've been connecting the issue with the equipment I've connected. But since yesterday they appear regardless disconnecting everything from UFX. All input channels are light on red crackling very loudly and after power cycle it takes around a minute and it's happening again. I suppose it might be a power supply issue (hopefully).

I'm living in Warsaw / Poland - can you possibly provide a contact to the support here? Thank you!

Hi

Looks as I have the same problem as descibed in this thread. If yes it needs hardware repair.

Question:
Who can repair in Germany?
Who can repair in Switzerland?

Problem:
No Hardware Output on analog ports (AN1....AN12)
Sporadically appearing crackling noise on HARDWARE INPUTS which is then permanently crackling while nothing connected to inputs!
1)    Totalmix is showing signal on AN1...AN12. but no signal on HARDWARE OUTPUTS (TRS, XLR, Phones jack)
See: Pic1

2)    HARDWARE OUTPUTS show signal in Digicheck although no pysical signal on analog HARDWARE OUTPUTS.
See Pic2

3)    Signal on HARDWARE INPUTS with NO SIGNAL connected to inputs! Constant crackling sound which can be heard at outputs, phones output as well.
            This crackling sound appears after a while. Switching on 48V on Mic
            See Pic3

4)    If Hardware Output „AES“ is selected it works correct: correct signal on AES, Hardware Output Digital is okay.
See Pic4

5)    Sometimes after a while, switching for and back Mix1..8, or switching on/off Mic48V it works again, i.e. signal on physical HARDWARE OUTPUTS AN1..AN12

6)    After shutting down PC and after that the UFX, while it was working after restarting first UFX then computer there is often the same problem as described in 1)

7)    Switching off UFX and again on, the crackling stays. USB disconnected, also nothing connected to HARDWARE INPUTS

8)    How is it possible that Totalmix and Digicheck show signal on HARDWARE OUTPUTS, but there is no physical signal on the XLR, TRS phonejacks.

9)    What might be the problem? Analog part hardware defect? FW? Driver? Totalmix? USB connection? Some configuration in Totalmix?

Hi

the error message is:

you need to provide administrator permissions to copy to this folder

May be I can give the permission, however just installing the driver including Totalmix worked witout any flaw.

the reason is I ma trying to update: my UFX has some strange problem. I reported in the other thread.
-No sound output
-sometimes sporadically noise on input while niothing is connected

Sometimes the UFX works normal sometimes it just does not.
If it ones works, shutting down the computer and UFX and starting again, mostly it will not work.
Often Totalmix asks if want to use Totalmix settings or UFX settings.

Before it never asked.

Some OP suggested its a power supply problem.

Before I send it for repair I would like to be sure its a hardware issue.

The is a built in Diagnosis in UFX. How to start it?

Peter

Hi everybody!
I'm experiencing the same problem with my UFX (bought in 2012).
I switch it on and after 5/10 minutes it starts to produce an awful noise from the left speaker, going progressively to stereo in some seconds. All the analog input channels are receiving a "fake" signal, as displayed in the TotalMix FX app and in the hardware input leds.
The noise disappears after 30 seconds, then I can use the UFX without any problem.

I'm going to change the power suply, many thanks to the OP for sorting out the problem :-)

Peter

Hi

the UFX works again after repairing the power-supply. It was a capacitor problem (defect electrolytic capacitors).

Peter

DSP errors only affect Echo and Reverb. Power supply issues affect everything.

Hello! Thank you, mikesmales, for posting about this two years ago! Since just a couple of weeks I'm having this exact problem with my 10 year old UFX. Glad you found a solution! I'm trying to find out how to do the hardware diagnosis thing on mine. Do I need a separate app of any kind for that?
