I very seriously doubt that there is any form of automatic gain control on the input of the 950s analog to digital stage (yes, it is 48Khz and 24 bit). They are undoubtedly relying on the maximum output of any device connected to the DSP inputs being in the neighborhood of 2.0 volts. As you might know, in the analog DSP mode, the noise (hiss) level of the 950 is at a worst case level. Perhaps being a bit conservative on the sensitivity of the ADC is why this mode is hissier than the other modes. Of course _theoritically_ a 24 bit digital word has a S/N ratio of 144db - clearly this is bullshit in the real world, as no possible device on the planet Earth, lacking perhaps liquid nitrogen cooling to near absolute zero degrees, could be this quiet. At least the lower 4 bits are recording nothing more than random electron noise, especially in an ADC that cost only a few dollars. If course the marketing department would disagree
