A&H AB168 Portable AudioRack 16in / 8out 48KHz for QU / GLD / SQ

The DX168 is a rugged, 96kHz portable expander for adding remote I/O to a dLive, Avantis or SQ system, or to the AHM-64 audio matrix processor.

Each DX168 features 16 mic preamps with independent Phantom Power LED indicators, plus 8 XLR line outs.

The DX168 connects via a single Cat5e cable to the dLive Surface, MixRack, SQ mixer, Avantis mixer or upstream DX168 via a secure EtherCon port. A second locking EtherCon port is provided for redundant connection to compatible hardware, or for daisy-chaining to a downstream DX168 for additional remote I/O.

The Expander’s rugged design, with hard-wearing rubber bumpers, allows it to be placed directly on the stage floor during performances. Weighing in at just 4.8kg and featuring a sturdy carry handle, the DX168 offers the convenience and portability needed in rental, education, houses of worship and many other environments. An optional 4U rack mounting kit is available which allows installation in industry standard 19-inch racks.
