D21m System
‘64 channel’ allowing maximum usage of the available channels. This switch
may only have to be set to ‘56 channel’ protocol for operation with third-
party MADI devices (in case no remote I/O box is connected to the MADI
I/O card).
If 64 channels of MADI transmission are required when working at 96 kHz,
the redundant MADI line can be used as a ‘channel extension’ for transmit-
ting the MADI channels 33-64 (29-56). This must be set accordingly with a
DIP switch on the MADI I/O card inserted in the hub frame.

SCore &
I/O Frame
Notes Both the remote I/O box and the local hub frames are standard D21m frames,
providing the possibility to insert any I/O card available for the D21m I/O
system. The hub frame may therefore also be used for any audio I/O located
close to the DSP core.
Up to 6 remote I/O boxes can be connected per hub frame, except in the first
hub frame, where one slot is occupied with one ADAT card (or AES/EBU
card in case of operation with the Performa core) in order to provide I/O for
monitoring and talkback of the desk.
