Audio Cable Wiring Guide
Inputs and outputs of audio devices are symmetric or asymmetric.
The main advantage of the symmetric lines is the better protection
against the noise therefore, they are widely used in the professional
audio industry. Symmetric audio is most often referred to as balanced
audio, as opposed to asymmetric, which is referred to as unbalanced
connectors so we would like to help users assembling their own audio
cables. See the most common cases below.
ATTENTION! Symmetric and asymmetric lines can be linked with
passive accessories (e.g. special cables), but in this case half of
the line level is lost.
ATTENTION! There are numerous types of regularly used connector
and cable types to connect audio devices. Please always make sure
ATTENTION! Never join the phase-inverted (negative, cold or -)
poles (either right and left) to the ground or to each other on the
output side, as this can damage the unit.
INFO: Use a galvanic isolation in case of a ground loop.
