...Audya5 dont have a digital input & output?
So, the specifications given by Ketron are wrong?   
 Hi,
the ( my 

 ) Audya5 has NO SDPIF digital In- and Output.
So obviously the english Ketron - flyer is wrong !
Edit : I just had a look into the german version, itīs faulty as well   
 Or meanwhile they have changed it and new Audya5īs have it built in again.
