Compatible with any SQ digital mixer or dLive system fitted with a gigaACE I/O option card, the Allen & Heath DX Hub is a remote audio-networking hub, which provides four DX Link ports, each carrying 32x32 I/O of 96 kHz audio. It allows you to connect one DX32 expander or up to two DX168/DX164-W expander units to each of the DX Link ports and add up to 128 remote inputs and 64 remote outputs to your system. With dLive, multiple DX Hub modules can be used for further expansion or for dual redundancy.
