This system interface allows for seamless integration of digital partylines in matrix intercom environments. It converts four two-channel CAT 5 matrix ports to four phantom powered beltpack lines. The beltpacks are connected to the C44 via standard 3 pin XLR cables. Up to 16 beltpacks can be daisy-chained on each line; one C44 can power up to 38 beltpacks. For stand-alone use the device features an integrated 24×24 ports digital intercom matrix, which can be configured via Riedel’s audio assignment software. Pre-programmed configurations can be loaded via DIP switches on the front.

Full digital interfacing is provided for Artist and Performer 32 matrix systems. Analog 4-wire I/Os and GPIs are provided for interfacing to 3rd party intercom systems. The C44 provides short-circuit protection on each powered line individually. Separate DC inputs and outputs at the rear of the unit can be used to provide redundant power.
