Hi there! I’ve determined that past about -3dB, the UR series of interfaces will clip. The only real solution is setting the main output in dspMixFx to about -3.25 dB. This is pretty disappointing, as digital attenuation is not transparent. I’ve emailed Steinberg about this, but who knows if it will reach anyone who can do anything about it.
