G EQ

Inspired by Revalver® Original (Plug-in)

It is a fixed-band, typical live/FOH style graphic equalizer (similar to classic 8-band stage EQs)

GENERAL FUNCTION

  • Allows you to quickly change the sound
  • Each slider controls one specific frequency

Ideal for:

  • quick live fix
  • general shaping
  • elimination of feedback

Less precise than parametric EQ, but faster

Control Parameters

FREQUENCY BANDS

Each band has:

  • Typical range: approximately −12 → +12 dB
  • Control a precise area of ​​the spectrum
60 HzdB
  • Sub bass

Effect:

  • boost → depth
  • cut → less rumble

useful for:

  • Bass
  • kick
  • avoid stage vibrations
100 HzdB
  • Bass/punch

Effect:

  • boost → body
  • cut → less boom

fundamental area for:

  • acoustic guitar
  • male voice
200 HzdB
  • Low-mid

Effect:

  • boost → heat
  • cut → minus “mud”

It is often cut slightly

400 HzdB
  • Boxiness

Effect:

  • boost → closed sound
  • cut → more cleaning

Critical frequency

800 HzdB
  • Central high schools

Effect:

  • boost → “nasal” presence
  • cut → more open sound
1.6 kHzdB
  • Presence

Effect:

  • boost → definition
  • cut → softer

Important for intelligibility

3.2 kHzdB
  • Attack

Effect:

  • boost → clarity
  • cut → less aggressive

Critical zone for voice

6.4 kHzdB
  • Brilliance

Effect:

  • boost → air
  • cut → less harsh

Check the highs

LeveldB
  • Range: approximately −12 → +12 dB
  • Global EQ output

Compensates for volume variations

Pro Tips

  • fixed bands → less precise
  • excessive boosts → artificial sound
  • too many cuts → energy loss

Better to make small interventions (±2–4 dB).

Live workflow:

  • cuts problematic frequencies
  • then add presence
  • avoid extreme boosts

Quick Reference

  • 60 Hz: sub
  • 100 Hz: bass
  • 200 Hz: low-mid
  • 400 Hz: boxiness
  • 800 Hz: mediums
  • 1.6 kHz: presence
  • 3.2 kHz: attack
  • 6.4 kHz: brilliance
  • Level: output volume
