DN9650/DN9652 Network Bridge
Operator Manual 25
Although there are no operating procedures associated with the DN965X, this chapter
shows you how to create a MADI split.
Using a MADI module as a MADI split
One of the features of the MADI card is that it allows you to create a MADI split. This is
because the MADI card has both optical and co-axial connections, which can both be
enabled simultaneously in the software (see “Setting up a network module” on
page 19). This allows outgoing audio from the DN965x to be received simultaneously
on both remote systems. However, this configuration has some very real limitations as
compared to a real split (see “Limitations” on page 25).
Typical example of a DN9650/DN9652 connected in a MADI split configuration
>> To configure the MADI module as a MADI split
• Set the unit MADI card as clock source (for example, choose master, onboard
oscillator, WCLK etc.).
• One format (for example, optical) connected in a loop (Tx and Rx) as usual to a
remote system (MADI slave).
• The other format (co-axial in this case) connected by just the Tx connection on the
module to another remote system (also MADI slave).
Limitations
The limitations of using the MADI module as a MADI split are as follows:
• Incoming audio to DN965x unit is only available from one remote MADI system.
• There is no clock domain separation between the two remote systems.
• If the remote system with the bi-directional link goes down or the link is
disconnected the other remote system loses its audio feed.
• Errors at the other end of the uni-directional link cannot be detected.
