PA series Digital Out SPDIF Samplerate

What samplerate of PA series mixers (S/PDIF Out), 44,1 or 48kHz or other? Does anybody know? There are no mentions either in the documentation or on the forums.

I found the following:

The SPDIF output is 24-bit, 48KHz, and is set to Professional mode, so no Copy Protection bit is set, and duplicates of the digital recordings can be made. (Source)
