The Allen & Heath AR2412 is a 24 XLR input, 12 XLR output AudioRack. Adding an AR2412 to your Qu system lets you position some or all of your I/O up to 120m from the Qu 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. The Allen & Heath AR2412 also includes a Monitor port for connection to ME-1 personal mixers, and an Expander port for daisy chaining to an AR84 AudioRack (Qu-24 only).
