Allen & Heath AR2412 AudioRack dSNAKE I/O for Expansion

Description

Details

The Allen & Heath AR2412 is an audio interface rack for the Allen & Heath GLD and Qu digital mixing systems. It provides 24 remote controlled mic/line preamps and 12 XLR line outputs. It connects to the mixer over a single Cat5 cable using the Allen & Heath dSNAKE protocol. An AR84 or AB168 AudioRack can be connected to the AR2412 to expand the number of system inputs and outputs. A dedicated Monitor port allows connection to Allen & Heath ME personal mixing system.

The AR2412 is simply an audio interface. It cannot be used by itself. It must connect to the GLD or Qu mixer which is where the audio is processed.

The AR2412 is not compatible with Allen & Heath iLive Series components or ACE connection.
