The AR2412 is a 19” rack mountable remote audio unit for all Allen & Heath digital mixing systems
compatible with the dSnake protocol. It provides 24 remote controlled mic/line preamps and 12 XLR line
outputs.
Using a single network cable, the AR2412 can be connected directly to the mixer, the expansion port then
allows a cascaded (daisy-chain) connection to an AB168 or AR84.
A ME personal monitoring system can also be connected to the dedicated Monitor port provided or a
cascaded AB168.
A maximum of two dSnake remote units can be connected to each mixer’s dSnake port.
The AR2412 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 AR2412 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
www.allen-heath.com for more information
on connecting, patching, and controlling the AR2412 with your system.
Cat5e (or higher) STP (Shielded Twisted Pair) 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 www.allen-
heath.com/ahproducts/cat5/ for more details.
