Expansion Configurations
Expansion systems may be achieved through a combination of hardware and software setup.
There is no digital expansion or ribbon cable. Expansion systems are only possible with analog
audio.
Sources are shared across multiple units via jumping bare copper CAT5e/6 cables from one unit to
the next.
