Something to edit. If i set the Ref level to +7 it changes automatically to +13 after switching to lineout and back zo phones. i am confused...
Edit2: here is something from the yamaha manual:
"Selects whether to activate the attenuator for the balance input (AUDIO 4) so that you can avoid sound distortion when high-level signals are input.
Activate the attenuator when connecting an audio device which outputs signals of 3 V (RMS) or higher to the AUDIO 4 (XLR balanced input) jacks."
So i guess it's 3V there? What would be a good clean signal from the ADI DAC? which settings to use?
Hi there! Check the RME ADI 2 manual on page 62:
Which level setting is recommended?
There are a total of four hardware reference levels available, with the XLR output having a 6 dB higher level. With Hi-Fi the setting +7 dBu (equals +4.78 dBV or 1.73 V RMS) is recommended. This setting causes an ADI-2 DAC to output level similar to that of many CD-players. In case it is still too low simply change to +13 dBu (+10.8 dBV, 3.46 V RMS).
When I used to have an integrated amp, I set the DAC to a fixed +13 dBu output, with volume locked at 0 dB (+ 7dBu makes me go too high on the amp volume pot).
From what we can read on the Yamaha manual, I would go with + 7 dBu (or + 13 dBu with the attenuator activated on the Yamaha, but it seems to complicate the process for no reason).
And if you need to translate dBu in V RMS, this free online tool is very convenient:

And don't forget that the XLR outputs of the RME ADI-2 DAC are 6 dB louder, so you must set +1 dBu in the menu to achieve + 7 dBu on the XLR output.
