Phase button

A description of the technology and function of the phase button as found in mixing consoles.

The mic preamp (preamplifer) is where the input signal is conditioned so that
it is suitable for further processing in the console.

The phase button inverts the signal polarity so that positive becomes negative
and negative becomes positive.

This is useful in two ways:

  • It is not uncommon for a mic cable to be wired incorrectly in inverted polarity.
    With a single mic this is generally inaudible. When two mics are used for
    stereo, and one is inverted, then the resulting out-of-phase sound is definitely
    noticeable. In many situations it is better to use the 'quick fix' of the
    phase button, then repair the cable later.

  • When many microphones are used close together, as on a drum kit, the spill
    (leakage) between the mics can cause unpredictable interference effects. It
    is good to experiment with the phase buttons. Often, pressing the phase button
    on one of the channels – you have to experiment to find out which – will improve
    the overall sound.
