Pro EQ3

PreSonus

Where to get itIncluded with Studio One. It is part of that DAW, not a separate download.presonus.com

Pro EQ3 is an eight-band parametric equalizer with optional spectrum metering, variable multimode filters for low-cut, high-cut, low-frequency, and high-frequency bands, and dynamic mode controls that trigger adjustments based on signal amplitude. It includes band soloing, Auto-Gain output leveling, and an optional phase-linear low-cut filter, making it suitable for precise, musical equalization across mono or stereo tracks.

Written from the manual and checked against it. How we check

Key Features

01Eight-band parametric EQ with peaking and shelf filters
02Phase-linear Low-cut (LLC) filter with 20/50/80 Hz selectable frequencies
03Low-cut and high-cut filters with 6, 12, 24, 36, and 48 dB per octave slopes
04Low-frequency and high-frequency multimode filters (Peaking or Shelf at 6, 12, or 24 dB per octave)
05Dynamic Mode on LF, LMF, MF, HMF, and HF bands (Threshold -90 to 0 dB, Amplitude -24 to +24 dB)
06Spectrum metering: Third Octave, 12th Octave, FFT Curve, or Waterfall display with 20 Hz to 20 kHz range
07High Quality mode with 2x oversampling for more accurate equalization
08Sidechain input for comparing frequency characteristics and enabling reactive Dynamic Mode

Things to Try

  • 01Use the 12th Octave spectrum display mode to identify problem frequencies by note value on the keyboard graphic
  • 02Set Dynamic Mode Threshold at -90 dB to -0 dB and Amplitude from -24 to +24 dB to trigger reactive EQ cuts or boosts based on incoming signal level
  • 03Enable High Quality mode for 2x oversampling when accuracy is more important than CPU load
  • 04Engage Auto-Gain to automatically match output level to the original input-signal power, ensuring 0 dB in equals 0 dB out
