DSD PreAmps
The Anubis Premium has been designed in order to be able to benefit from the +3.1 dB SACD
headroom offered by DSD, as per the scarlet book standard. This is made possible thanks to the
gain applied in the digital section post AD just prior to the sigma delta 1-bit modulator. The gain
can be adjusted b0dB and +66dB in DSD mode. In Line mode, with a gain of +6dB, an
input of +21dBu will generate a signal of +3dB SACD, in Mic mode, with the same gain, an input
of +9dBu would generate a signal of +3dB SACD.
To benefit also from this +6dB headroom in DSD on the DA outputs, we recommend our users to
set the Output Attenuation to -6dB on each DA module configuration page.
Reference : 0dBFS (PCM) = 0dB SACD (DSD)
