The AB168 is a portable, rugged audio interface box for the Allen & Heath GLD and Qu digital mixing
systems. It provides 16 remote controlled mic/line preamps and 8 XLR line outputs. It connects to the
mixer over a single Cat5 cable using the Allen & Heath dSNAKE protocol. A second AB168 can be
connected to the AB168 to expand the number of system inputs and outputs.
The AB168 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 AB168 is not compatible with Allen & Heath iLive Series components or ACE connection.
Refer to the GLD User Guide AP8561 and Qu User Guide AP9372 for instructions on connecting and
using the AB168 with your system. Refer to the Allen & Heath web site for more information and suitable
Cat5 cables.
The AB168 can be operated horizontally with the connectors facing upward
or sideward, or vertically to save space on stage. It can also be mounted in
a 19" equipment rack or case using the optional AB168-RK10 kit.
