AR84 is an 8 XLR input, 4 XLR output AudioRack. Adding an AR84 to your Qu system lets you position some of your I/O up to 120m from the Qu mxer, connected over a single Cat5 cable running Allen & Heath’s dSNAKE protocol. dSNAKE provides control to the remote preamp, and all mic preamps are scene recallable.
