IMPORTANT!
Take extra care when connecting Quad AES as it is very easy to connect the
wires in the wrong order. Although dCS puts messaging in data streams to
allow equipment to sort this sort of problem out itself, not all other
manufacturers do. If there is no messaging in the data stream, the only
indication that this has happened is poor audio quality. Labelling the cables
is a sensible precaution.
