PASSIVE EQ

Controls

• Low Freq20 Hz / 30 Hz / 60 Hz / 100 Hz — The low frequency for both low controls.
• Low Boost0 to 10 — Low shelf boost (up to +13.5 dB).
• Low Atten0 to 10 — Gentler low shelf cut a little higher; with Low Boost it gives the classic bump with a dip above it.
• High Freq3 kHz / 4 kHz / 5 kHz / 8 kHz / 10 kHz / 12 kHz / 16 kHz — The frequency of the high peak.
• High Boost0 to 10 — High peak boost (up to +18 dB).
• Bandwidth0 to 10 — Width of the high peak: 0 is sharp, 10 is broad.
• Atten Freq5 kHz / 10 kHz / 20 kHz — The frequency of the high shelf cut.
• High Atten0 to 10 — High shelf cut (down to −20 dB).
• Tube0 to 100% — Drive of the tube stage (even harmonics).
• Output−12 to +12 dB — Output level.

Best uses

• Weight on kick and bass with boost and attenuation together
• Air and presence on vocals
• Broad tone shaping on the mix bus or master
• Warming up with the tube stage

Properties

Input → low shelf boost at 1.2 × Low Freq → low shelf cut at 2.2 × Low Freq → high peak at High Freq (Q from Bandwidth) → high shelf cut at Atten Freq (each skipped at 0) → tube stage (asymmetric tanh, 10 Hz DC blocker, skipped at 0%) → Output. Zero latency; every control at 0 leaves the sound untouched.
