= lock to MADI
When a module is in router mode (56 or 64 MADI) it can only use the local AES reference. In 56 or 64
Channel MADI Transcoder Mode it has the option of locking to the 1st MADI input using Vari-Speed.
6.2.4 Internal Expansion
The audio modules (9305 & 9400) have been designed with internal expansion ports that connect to the
motherboard. The routing modules are interconnected within the frame to allow mix and match
analogue and digital systems by fitting any combination of 9400 and 9305 modules.
Figure 32 shows how the 9400/9305 cards are expanded with 4 cards in a single frame, the maximum
supported by the module and frame architecture. The 9400 analogue audio module has 36 stereo input
channels and 36 stereo output channels. The 9305 digital audio card has 36 AES inputs and 36 AES
outputs. Each card encodes up to 36 I/O + 1 MADI (56 or 64 channels) into an internal format which is
fed to the expansion inputs of the other cards in the system. Each card can therefore route any of the
frames inputs to any of its own outputs.
