Allen & Heath AR84 is an 8 in, 4 out audio rack, compatible Qu, Avantis and SQ mixers.
Each AR84 adds 8 XLR inputs and 4 XLR outputs to a system. Adding an AR84 to your system lets you position some of your I/O up to 100m from the mixer, 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.
