DX168

The DX168 is a portable, rugged I/O Expander for the Allen & Heath dLive and

SQ digital mixing systems. It provides 16 remote controlled mic/line preamps

and 8 XLR line outputs. It connects to the mixer over a single Cat5e cable.

A second DX168 or a DX164-W can be connected when running in Cascade

mode. Alternatively, a redundant connection can be made to compatible

hardware.

The DX168 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”

rack or fligthcase using the optional AB1608-RK19 kit. A hard-wearing padded

polyester carry case is also available, A&H part number AP9932.

Front panel

 Input sockets Balanced XLR mic/line inputs with +48V Phantom Power

indicator. The preamps are built into the DX168 and their Gain, Pad and +48V

are controlled from the mixer via the DX link.

The +48V indicator detects voltage at the socket whether supplied by the

DX168 or received from an external source.

 Output sockets Balanced XLR outputs operating at nominal +4dBu

level.
