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 specified by the AES (Audio 
Engineering Society).
