A949.0412
The D21m HD card S provides the link to the DSP core systems. Each input
and output can handle up to 96 channels in each supported sampling rate (in
combination with the Performa core, the number of I/O channels is restricted
to 48). The system clock used is taken from the host DSP system, so no extra
synchronization is needed.
The card detects all other I/O cards that are inserted into the D21m system
and displays their presence on the front panel of the frame. Once all audio
interface cards are plugged in, pressing the
RECONFIG
key on the front panel
confirms the configuration to the system. Then all cards are activated and
their audio signals are fed into the HD link.
