Unbalancing a Line
In most studio, stage, and sound reinforcement
situations, there is a combination of balanced and
unbalanced inputs and outputs on the various pieces
of equipment. This usually will not be a problem in
making connections.
•
When connecting a balanced output to an unbal-
anced input, be sure the signal high (hot) con-
nections are wired to each other, and that the
balanced signal low (cold) goes to the ground
(earth) connection at the unbalanced input. In
most cases, the balanced ground (earth) will
also be connected to the ground (earth) at the
unbalanced input. If there are ground-loop prob-
lems, this connection may be left disconnected
at the balanced end.
•
When connecting an unbalanced output to a
balanced input, be sure that the signal high
(hot) connections are wired to each other. The
unbalanced ground (earth) connection should be
XLR Connectors
Mic/Line 4 cards use 3-pin female XLR connec-
tors on the MIC inputs. They are wired as follows,
according to standards specifi ed by the AES (Audio
