AR84
Getting Started Guide
The
AR84
is a 19
”
rack mountable remote audio unit for all Allen & Heath digital mixing systems
compatible with the dSnake protocol. It provides 8 remote controlled mic/line preamps and 4 XLR line
outputs.
Using a single network cable, the
AR84
can be connected directly to the mixer or cascaded from an
AR2412
or
AB168
.
A maximum of two dSnake remote units can be connected to each mixer
’s
dSnake port
.
The
AR84
is used to increase the number of I/O sockets in a system and position both sockets and
AD/DA conversion close to the source/stage. It will not increase the number of processing channels
available in the system and must be connected to a mixer where the audio can be processed and routed.
Compatibility and Cable
The
AR84
uses the 48kHz dSnake protocol, which is a layer 2, fast ethernet protocol designed for point-
to-point connections. This means it can be connected to the dedicated dSnake ports included on the
GLD
and
Qu
systems or used with the intelligent SLink port which can switch to a dSnake mode.
Refer to the latest documentation for your mixer available from
on connecting, patching, and controlling the
AR84
with your system.
Cat5e (or higher) STP (
S
hielded
T
wisted
P
air) cable should be used, with a maximum cable length of
100m (330ft) between each unit. Use of passive couplers to join cables will reduce this distance.
High-quality touring grade cables are available through your A&H dealer. Please see
