TyPiCal MC3 SeTUP
The MC3 Monitor Control is typically connected to the output of your mixing console, digital
audio interface or laptop computer represented as a reel-to-reel machine in the diagram. The
outputs of the MC3 connect two pairs of stereo monitors, a subwoofer and up to four pairs
of headphones.

BalanCed vS UnBalanCed
The MC3 can be used in either balanced or unbalanced mode by setting the configuration
(CONFIG) switch on the rear panel to suit. Because the main stereo signal path through
the MC3 is passive, like a “straight-wire”, you should not mix balanced and unbalanced
connections. Doing so will ultimately “un-balance” the signal through the MC3. If this is done,
you may encounter crosstalk or bleed.
For proper performance always maintain either
a balanced or unbalanced signal flow through the MC3 and set the CONFIG switch to
the appropriate setting. Most mixers, workstations and near-field monitors can be used in
either mode, so this should not pose a problem when used with the proper interface cables.
The diagram below shows various types of balanced and unbalanced audio cables.
