Interconnect cables
We recommend the use of high-quality screened cables
that are designed for the particular application. Other
cables will have different impedance characteristics
that will degrade the performance of your system (for
example, do not use cabling intended for video use to
carry audio signals). All cables should be kept as short as
is practically possible.
It is good practice when connecting your equipment to
make sure that the mains power-supply cabling is kept
as far away as possible from your audio cables. Failure to
do so may result in unwanted noise in the audio signals.
