TDM Expansion
TDM Expansion
You can use any two Concerto frames to create larger Audio matrices. The
matrices can be either Stereo or Mono. A Time Division Multiplex (TDM)
sub-module is attached to one of the Audio modules in each frame.
For matrices under Jupiter control, the slot position of the Audio modules
with the TDM sub-modules will depend on the architecture of the expan-
sion frame. If you have put a Video module in slot 1 of the expansion frame
and the module in slot 2 is an Audio module, then the Audio modules with
the TDM sub-modules would go in slot 2 on both frames.
For matrices under Encore control the Audio modules with the TDM sub-
modules have to be in slot 1 in both frames.
A few examples of supported architecture are shown.
TDM: 256x256
In this configuration all modules in both frames are Audio modules.
Figure 14 shows the Signal Flow of a 256x256 Stereo matrix.
