question about SPDIF spec

  • Hi guys,


    I am double checking my digital cabeling and have stubled upon different specs for SPDIF coax voltages.


    Kemper spec from the manual only states "S/PDIF IN/OUT: 44.1/48/88.2/96 kHz (24 bits) with RCA phone connectors for coax cables (Master only) " no mention of voltage


    My RME interface has two options "Output level Professional 1.4 Vpp, Consumer 0.7 Vpp"


    So my question is:

    What voltage does the Profiler want to see? Don't want to damage the input... So what to set?


    Sorry, if this has been talked about elswhere, but I could not find a definitive answer in the threads I found via search.


    Thanx for reading!
