Key takeaways

  • What the performer hears — wedges on stage or in-ear monitors, mixed separately from FOH.
  • IEMs give consistent sound, far better hearing protection and much lower stage volume, which in turn makes the FOH mix cleaner.
  • Ask for what you need in one clear sentence — 'more of my vocal, less of the guitar' — rather than 'more me'.
  • Watch out: pushing wedge volume until the stage is louder than the PA.
  • Sits under live sound and performance in this glossary, with 2 primary sources below.

MONITOR MIX / IEMS IN DEPTH

Monitor mixes are what performers hear on stage, either through wedges or in-ear monitors. IEMs give consistent sound, far better hearing protection and much lower stage volume, which in turn makes the FOH mix cleaner.

How it works in practice

Ask for what you need in one clear sentence — 'more of my vocal, less of the guitar' — rather than 'more me'.

The mistake people make

Pushing wedge volume until the stage is louder than the PA. At that point the audience is hearing the stage, not the mix.
