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.

 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.

 DX A

EtherCon port for connection to the mixing system. The cable
carries the audio signals as well as preamp control and system status data.

 DX B

EtherCon port for daisy chaining of a second unit or cable
redundancy. Switch to Redundant for 2 cable connection to compatible
hardware e.g. dLive S Class or DX Link card. Switch to Cascade for connection
to a second DX168 or DX164-W unit.

 Mains power input

IEC connector and fuse for the built-in universal
voltage PSU. This accepts voltages from 100 to 240V AC 50/60Hz. Secure the
cable to the plastic P-clip using a T20 screwdriver.

 Vents

Ensure good ventilation at the sides and back of the unit. Avoid
obstruction of vents while operating. Avoid dirt or liquid ingress.

Cables
Cat5e or higher STP cable is required for DX Link connections with a maximum
cable length of 100m per connection.
Allen & Heath can provide a number of Cat5e and Cat6 cables suitable for use
with the DX Hub:
