Figure 33: Audio Modules: External Expansion
The MADI ports can be used as a form of expansion when a module is configured to router mode.
However each frame would need to use a different control ‘LEVEL’ and port numbering would be
allocated per frame.
6.2.6 Audio Port Numbering
Pyxis Audio modules support Analogue Audio, AES, and MADI formats. The ‘D’ type sockets on the rear
panel (refer to section 7.2 for details) support the first 36 channels; Analogue or AES depending on the
audio module. The MADI channels are available through the BNC connectors.
If a single module is being used then the audio signal pairs are 1–36 and the MADI pairs are either 37-
64 for 56ch MADI (28 pairs) or 37-68 for 64ch MADI (32 pairs).
A 3U frame can have up to four modules fitted.
If they are configured as separate levels then the numbering will be per module,
If they are configured to the same control ‘LEVEL’ and ‘DEST OFFSET’ set as per the tables
below the modules will be numbered as one large router (up to 272x272 in 64 Channel MADI
mode)
o
It is not possible to mix MADI modes across modules working as one logical level;
Table 27 and Table 28 detail the audio port numbering in each MADI mode and using each control
system. Nebula routes only stereo pairs, Nucleus allows routing of mono Channels.
