Unbalanced Stereo Connections
Some equipment is manufactured with a single jack for two-channel
transmission, usually for stereo headphones or microphones. These
jacks have three conductors; one signal conductor for each channel,
and a ground which is shared by the two. Since it is a two-channel
unbalanced connection, it requires connection to two XLR connectors.
The first configuration shown is preferred because it offers the highest
immunity to interference and noise. However, it may be difficult to
construct because of practical connector limitations. The other two
configurations are also valid for testing applications, but are
considerably more susceptible to interference and grounding problems.
