4.6 CD I2S / SPDIF input
The performance of these input signals is actually limited by the DAC output, as described in
chapter 4.7.
The digital CD input can be used as an alternative input for the analogue CD.
RDS traffic information reception from radio signals in this mode is possible; the decoder is
s till operating
