Source index 3 defines a set of sources, one for each level, that comprises - levels
1 and 2 as source 4, levels 3 - 6 as source 3 and levels 7 and 8 as source 1.
Source and destination associations have different properties due to the
distributive nature of the router i.e. one source may feed to many destinations but
a destination may only have one source routed to it. One user may route the same
source as another without affecting each other. However, routing a source to the
same destination as another user obviously does affect each other. Therefore, a
source association index may contain the same source number on a given level as
another index but a destination association index should contain unique physical
destination numbers. This avoids operational confusion as the system does not
check or prevent this condition.
A user may require one button to set the sources across all the levels and another
button to set only the audio sources. In order to do this special associations are
used.
