Combining Balanced Cables

- Jun 08, 2018-

The standard connector for balanced audio is the 3-pin XLR.

Unfortunately there is no official standard for wiring balanced audio cables, but the most common configuration is:

Pin 1: Shield (Ground)

Pin 2: Hot

Pin 3: Cold

 

Mixing Wiring Configurations

Using cables or equipment with different wiring configurations in the same system is a recipe for trouble. You may well find that audio signals start canceling each other out and leave you with nothing.

Many sound mixers have a "phase invert" switch on each channel. This swaps the phasing of the hot and cold pins to solve the mismatch problem.

Obviously the best plan is to keep your wiring consistent. Use the configuration above and you shouldn't experience too many problems.
