The Allen & Heath AR84 is an 8 XLR input, 4 XLR output AudioRack.
Adding an AR84 to your Allen & Heath 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.
