A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal 
but of opposite polarity when referenced to ground. An unbalanced line is generally a single-conductor shielded 
cable with the center conductor carrying the signal and the shield at ground potential.

control is required across the audible frequency spectrum.

When used with an audio spectrum analyzer the EQs can tune any acoustical environment -- from the studio to the

real-time spectrum analyzer or other types of audio environment analyzers are very useful in determining the 
amount of equalization needed.
