Hi,
I'm just fiddling with my UIMC204 interface to see how strong the distortion is on its outputs and how it depends on the Main Volume.
I connected one channel of the outpout (which normally goes to my monitor controller) to the left input. I set the input gain so that it it does not clip at the input.
The signal of the left input I checked with a spectrum analyzer playing a sine tome at 1 kHz. I don't know the absolute levels, but what I get is this:
In red you see the signal from the PC and in cyan the signal that goes from the interface output into its input. There's significant amount of distortion. I don't know if this is comparable with Amirs measurements: https://www.audiosciencereview.com/...ringer-umc204-hd-audio-interface-review.9856/ but it seems worse to me.
The main volume in this case is at 100% (~5 o clock). When I dial the volume back a bit to ~2 o clock it looks better, but I'm loosing 12 dB of volume, which is not acceptable. Does anyone know if the unit is really that s h i t t y?
