Featuring 16 microphone preamps, the AB168 is a portable remote AudioRack for use with the Allen & Heath GLD and Qu series in live and installation settings. The 16 mic preamps with Phantom Power indicators and 8 XLR line outs run on Allen & Heath’s proprietary dSNAKE protocol and is compatible with both the Qu and GLD ranges.

Adding an AB168 to a Qu or GLD system allows some or all I/O to be positioned up to 120m from the mixer. The unit connects over a single Cat5 cable to the Qu/GLD mixer or AR2412 AudioRack via a secure dSNAKE EtherCon port. A second EtherCon port is provided for daisy-chaining to another AB168 box or connection of a ME personal mixing system. AB168 auto updates its firmware to synchronise with the system.

The rack’s rugged design, including rubber bumpers, renders it highly roadworthy and allows it to be placed on the stage floor during performances. Weighing in at just 4.8kg and featuring a sturdy carry handle, AB168 is also designed for maximum convenience and portability.
