Topic: Low Input level on USB
I switched yesterday from the 'ADI2 DAC' fs to the 'ADI2 PRO fs BE'. I switched because I want to use the analog inputs for my turntable. That is function brilliantly, the sound is great.
I did a firmware update from 112 to 116.
I notice a strange difference between the two with my USB input. I have an Innuos MK3 mini attached through USB to the RME.
In the default factory setting of the RME DAC the input was high, mostly close to 0db. I had to switch the volume back to -30 to have a comfortable listening level.
On the ADI 2 PRO however the input level seems pretty low, around between -40, -45 db. The analyser is hardly showing anything.
I tried allready a few things. Like switching Ref Level (which is on +19) off and going to +24. But this doesn't seem to influence the input signal.
I also fiddled with different Horizontal Meter settings and put it on Dual.
The input of my phono preamp looks good working in preamp mode, and the analyzer is working accordingly fine.
Why is the input level of the USB showing so low compared to the ADI2 DAC?
ps: I don't complain about the quality of the sound. To my ears it is pretty much the same as the ADI2DAC. Even with this low input level I have enough power to a comfortable listening level.
