Which signal is used for audio input of the A-188-1 for this MP3 I assume
none but maybe I'm wrong.

If this is true you will hear probably the dirt effects of the BBD because
at position 4 the BBD is already out of it's specification (i.e. already
less than 10 kHz BBD clock). Please refer to page 3 of the user's manual
(remarks).
And you should operate the A-188-1 with a full level audio signal (as close
as possible to clipping) as the A-188-1 is an audio signal processor but not
planned to operate without audio input signal.

More details about the dirt effects of the A-188-1 (and their adjustment)
can be found in the A188-1 adjustment explanation:
