Analogue input signal path

Does the analogue input get digitised or is it a straight through path? Intrigued as the VU meters work with the analogue input but not DSD

First of all, I’m sorry for the late reply.
We were away last week to attend a hi-fi audio show in Germany.

RS250a and RS150b support digital output from analog in.

All inputs and outputs can pass each other.
However, in PC IN mode, only digital and analog outputs are supported through USB IN.

Thank you
