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.
