Topic: RME ADI 2 DAC FS line output distortion
Hi,
I am looking for some help / advice regarding my RME ADI 2 DAC FS line output distortion issue.
I have been using this DAC for months home between my digital source and my amp with these settings:
line output, auto ref level, +13dBu, 0dBr, NO EQ
No issues, great sound, happiness.
Tonight with the same setup I have experienced audible distortion coming out from my RME ADI 2 DAC FS.
I tested all the components in my setup, unfortunately there is an issue with the DAC.
I tested all the digital inputs of the DAC. Same issue with all the inputs.
There is no sign of any clipping on the display. EQs are OFF.
With headphone it sounds ok.
I tried to lower the output level:
+1dBu, -12,5dBr, NO EQ, sounds fine, but if I higher up with the level audible distortion arrives.
I tried to reset the DAC. It did not solved the problem.
It worked fine for months on "auto ref level, +13dBu, 0dBr, NO EQ", it worked fine this morning.
I tried with two other amps. Same issue.
The system sounds ok with another DAC.
What other things should I check or change to fix this issue?
It could be a setting issue or should I send it to a RME service provider for a hardware inspection?
I bought the DAC in 11/2019.
Thank you for your help!
