Transmission Outputs and Studio 1-3 Audio Connection Details
There are three studio interfaces to connect three individual studios to the unit. There is also
a transmission interface which carries the main transmission output and 2 balanced stereo
connections for interfacing with external units such as hybrids, or codecs, which you may
want to share between studios. These are all 25 way female D-Types and they each carry 4
balanced stereo pairs or 8 mono.
