EQ frequency map

What happens where in the spectrum?

The tool — try it now

An interactive map of the whole frequency spectrum from 20 Hz to 20 kHz. Click a range to see which instruments live there and what happens when you boost or cut it.

What you learn with it

Understanding the three EQ bands (LOW/MID/HIGH) on a DJ mixer. With them you can separate tracks cleanly in a transition and avoid bass clash.

Pro tip

The most important DJ move: during the transition, pull the LOW band of track A out while track B comes in. Then LOW on track A at 0 and track B at full — no bass clash, a clean transition.

Common mistakes

  • Boosting instead of cutting. The mix gets louder rather than clearer, and the meter goes into the red.

  • Leaving both basses in because it still works in the headphones. On a big system that is precisely where it turns to mud.

  • Leaving a knob all the way down and forgetting it. The next track then starts with no bass, and nobody understands why it sounds thin.

Recommended practice time

15–30 minutes

Take the time in one go — hearing and timing develop through repetition, not through reading.

You have it when you can run a transition without touching the mids — and the bass changes hands exactly once, not twice.

Questions about this tool

Why does a DJ mixer only have three bands?

Because three are enough to separate tracks from one another, and because three knobs can be worked blind. A studio EQ has more bands and is built for shaping a sound; the DJ EQ is built for taking away, under time pressure, with one hand. More bands would not help in the dark — they would be a source of mistakes.

Why is it always said to cut rather than boost?

Because boosting costs headroom and cutting makes room. Two tracks at once already bring more energy than one; boost on top of that and you end up clipping. Cutting achieves the same goal — the other track becomes more audible — without anything anywhere getting louder.

What exactly is a bass clash?

Two bass lines at once that are not playing the same note. It does not sound like two basses, it sounds like mud — the low range carries most of the energy, and two sources down there add up to an undefined rumble. Which is why the first rule of any transition is that only ONE track keeps its bass.

Why does hardly anyone touch the mids?

Because that is where a track is recognised: voices, melodies, the character of the synths. Taking the mids out makes a track unrecognisable rather than quieter. For a transition the bass usually suffices; the mids are the tool for the moment when two voices run at once.
