ATON's DH46X Expansion Router adds 6 zones of audio to the groundbreaking DH44 Digital Audio Router with DIGI-5 Technology. The DH44 is an end-to-end digital multi-source, multi-zone solution for superior sound quality with no signal loss. When multiple DH46X Expansion Routers are connected to the DH44, the system can distribute four audio sources (analog or digital) to as many as 28 zones.
