Topic: HDSP9652 SPDIF OUT -Internal/External Question

Hi
   I want to add a second HDSP9652 to my system and sync internally via spdif.  (I am aware that I will loose "SPDIF IN" on the 2nd card) My question- Will the "External SPDIF OUT" on CARD 1(Master) remain active, or will I also loose this output by syncing internally.
thanks
Mike
