5.8 Connection to the Performa Core
The Performa core is connected to the D21m I/O System in a similar way as
the SCore. The main difference is that the HD link connection from the core
towards the D21m I/O frame only carries up to 48 channels (at both 48 and
96 kHz). In order to implement a correct mapping of the I/O cards’ channels
to the HD Link, the “Performa Mode” switch (or jumper) must be ON on the
HD cards. In the Performa core, use of the PE-D21m card (A950.060622) is
mandatory. Each card implements one HD link input with up to 96 channels,
and one HD link output with up to 48 channels.
