Please note:
Starting with order nos. A949.041124 and A949.041323, resp., the MADI HD
cards have been equipped with the larger dual-slot front panel containing an
additional RS422 control connector (left picture). At the same time the MADI
HD card with RJ45 connectors (A949.0414) was introduced (right picture).
The D21m MADI HD card is plugged into an HD card slot in the remote I/O
box and provides the link to the hub frame. The two interfaces offer up to 64
audio channels with 44.1/48/88.2/96 kHz operation, together with embedded
control and user-accessible serial connection in each direction.
The auxiliary interface can be used as a redundant link or, in 88.2/96 kHz
operation, to extend the number of channels from 32 back to 64.
In slave mode, the card extracts the system clock from the incoming MADI
signals and provides it to the entire remote I/O box. It 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 MADI link.
The card can also be switched to master mode; it then runs with an internal
48 or 96 kHz reference.
