Balanced cables use two conductors for the signal, one positive and
one negative, in addition to the ground. This means a stereo application
requires two cables.
Balanced connections are far more resistant to electrical interference
and support runs of 98' (30 m). Longer runs have special considerations
and an engineer should be consulted. Although SMART products do not
feature balanced audio connections, you can use a Balun device to
convert unbalanced connections to balanced ones if you need to use a
balanced cable. SMART does not sell or support Balun devices, but they
can be used if implemented properly. Consult your reseller if you think
the use of a balanced cable with a Balun device is required for your
installation.
Powered connections can be balanced or unbalanced, and are only
used to connect an amplifier to a speaker. Powered connections use a
much heavier gauge of wire than standard connections, and the
connectors will be larger than a standard connector as well. In addition,
powered connections typically have a thicker, more durable jacket,
enabling easier runs across floors, under stages, and so on.
