Description:
An equalizer that goes beyond hardware
An operational amplifier that added power and harmonic density to decades of hits. Behavior acceleration engineers discovered it by accident. Fairuz takes both and pushes them into a realm the original hardware never offered.
Overview:
Each band passes through a true operational stage—voiced by discrete circuits that define what the EQ can do to the sound, not just the frequency. Push it, and it returns warmth, density, and harmonic weight. Pull back, and the signal becomes cleaner, more transparent. This character is always present, whether you’re shaping the frequencies or not.
Turn off the band, and the op amp remains in the circuit. Without drawing the EQ curve, you get the harmonic color that hardware EQs only produce with heavy boost. This is band saturation mode: the op amp’s character at a specific frequency, completely independent of your EQ movements.
Contour bands take the classic boost-and-cut technique—the one engineers have been reproducing for years with two separate filters at the same frequency—and make it a single band. One stroke. Focused boost, automatic complementary notch, no congestion in surrounding frequencies. Push the Fairuz to its limits: bold Contour boosts, full Hammer drive, and op-amp saturation in each group. Then blend back in with MIX to taste. The full character—as much or as little as you like.
Features:
Four-band op-amp EQ with three filter shapes: Bell, Contour, and Contour X2
Band Saturation Mode: decouples the op-amp from the EQ curve for frequency-focused harmonic character
Proportional Q: soft boosts remain wide, while high boosts are automatically focused
Stepped or Continuous Frequency: stepped points selectable by ear, with intentional gaps to avoid problem areas
Infrasonic TREMOR circuit: sub-bass foundation before the EQ input transformer
VOICE: harmonic drive that sets the tonal stage
Hammer output transformer: case, density, and saturation on the output
LO and HI output shelves with complementary behavior
dip HPF and LPF with switchable HPF position (before or after the transformer)
MIX: parallel wet-dry mixing without additional
DAW routing
Dual Mono: true stereo hardware behavior for buses and groups
Oversampling for best harmonic behavior at standard sampling rates
Zero latency
