Balanced connections
Balanced connections are generally immune to ground loops because the grounded
screen conductor is not used as a reference for the signal conductors. Instead, each
conductor of a balanced connection is a reference for the other, and any induced noise
is rejected because it is common to both conductors. The process of eliminating noise
like this is called common mode rejection (CMR), which is often measured as a ratio
(common mode rejection ratio (CMRR)). CMRR is dependent on the performance of the
sending and receiving circuits at either end of the connection.
