output circuit. We strongly recommend that you refer to your various equipment manuals to ￿nd out what is used in each case before hooking up to unbalanced lines.

When connecting a balanced output to a balanced input, however, you don’t need to know what kind of balanced output you are dealing with. Simply treat it generically.

XLR to XLR

OK for Microphones

Standard store-bought cable. Shield grounded at both ends. Positives: Good for microphones.

Negatives: May cause ground loops through the shield grounds if used to connect equipment together.

Preferred for Line Levels

Shield grounded at receiving end only.

Positives: Stops ground loops and reduces noise.

Negatives: None

1/4” TRS Phone to 1/4” TRS Phone Balanced Cables

OK

Standard store-bought cable. Shield is grounded at both ends.

Positives: Both ends are interchangeable.

Negatives: May cause ground loops through shield contacts.

BETTER

Custom cable. Shield is grounded at receiving end only.

Positives: Stops ground loops and reduces noise.

Negatives: Should be oriented so lifted shield is at sending end.
