Put simply, N22 replaces 4 balanced XLR cables with 1 shielded Cat 5e, Cat 6, and Cat 7 cable over distances of up to 100m.

Featuring our C.A.S.T. system, N22 distributes audio around studios or stages by repurposing the internal copper wires of shielded Cat 5e, Cat 6, and Cat 7 cable to transport balanced analogue audio to and from other C.A.S.T. enabled products - such as another N22.
