For the digital output, there is a switch available to define the content of the channel
status bits embedded within the digital audio stream. The channel status bits will be forced
to Professional Mode for sample rates above 48kHz, as they are not supported by the
Consumer Mode. For sample rates of 32kHz, 44.1kHz and 48kHz, the status bits can be either
set to Professional or Consumer Mode.
The bit depth of the digital output can be set to 16, 20 or 24 bits, with a psycho acoustic
noise filter used to dither signals below 24 bit.
