6. Connecting dSNAKE Remote Audio
The Qu mixer provides local sockets on its rear panel for all audio inputs and outputs. It can also work
with remote audio by connecting over a single cable ‘digital snake’ to an Allen & Heath AudioRack, or to
the Allen & Heath ME Personal Mixing System.
6.1 Connecting to a remote AudioRack
The Qu can connect to an Allen & Heath AudioRack so that the audio can be plugged into a rack on
stage and routed to the mixer over a single Cat5 cable ‘digital snake’ plugged into its dSNAKE port.
The ‘digital snake’ – dSNAKE provides a convenient,
single Cat5 cable alternative to the typical heavy
analogue copper multicore to connect many inputs
and outputs on stage. One cable carries multiple
channels of audio in both directions together with
remote control of the preamps.
Cat5 cable – Use STP (shielded twisted pair) Cat5e or
higher cables. Those with both foil and braided
screens provide shielding from interference and are
generally more rugged. Stranded core cables are less
prone to damage when kinked or repeatedly coiled.
Remote Inputs - dSNAKE inputs are mapped one-to-
one to the Qu input channels. They are not patchable.
 dSNAKE does not add channels to the mixer.
Choose either Local (rear panel) or dSNK (remote)
input for each channel.
Remote Outputs - Qu outputs can be patched to the
output sockets on the remote racks. These duplicate
the outputs on the Qu rear panel.
Connecting Qu to the AudioRack – Plug one end of
your Cat5 ‘digital snake’ into the Qu mixer dSNAKE port. Plug the
other end into the dSNAKE port of the AudioRack.
Connecting a second AudioRack – The AR2412 and
AB168 AudioRacks include an EXPANDER port. You can use this
to connect to an AR84 or AB168 AudioRack.
 The AR2412 AudioRack cannot be used as an expander in a
Qu system.
 You can connect up to two AudioRacks in a Qu system. This
includes the main rack and one expander rack.
Once connected and powered up, the Qu touch screen should
display the ‘dS’ icon in its toolbar to show that one or more
dSNAKE devices are recognised by the system.
dSNAKE carries:
 Up to 38 remote input signals
 Up to 16 remote output signals
 40 personal mixing sends
 Preamp control – Gain, Pad, 48V
The Qu mixer provides a locking Neutrik
EtherCon socket to protect the
connections and ensure suitability for
touring. Use a touring grade cable fitted
with locking EtherCon plugs.
Maximum cable length = 120m (396’)
depending on cable type. Recommended
maximum length = 100m (330’).
