SPLITTER AND MULTICORE

A split feeds one mic signal to both FOH and monitors; a multicore carries all the channels back to the desk in one run.

SPLITTER AND MULTICORE IN DEPTH

A splitter divides each input so FOH, monitors and a recording rig can share the same microphones, usually with transformer isolation to prevent ground loops. A multicore bundles many channels into one cable run between stage and desk.

How it works in practice

A transformer split lets you multitrack the show without affecting the FOH gain structure.

The mistake people make

Splitting phantom power across both paths. Only one desk should supply 48V, or the mics behave unpredictably.
