The Manley Dual Main EQ is a mastering-grade stereo passive equalizer that delivers the authoritative low-end weight, open musical highs, and dimensional depth that have made Manley equalizers a staple in world-class studios.
Designed for recording, mixing, and mastering engineers who demand both precision and musicality, the Dual Main EQ combines passive inductor-based equalization, high-voltage tube makeup gain, and custom Manley Iron transformers to produce rich, three-dimensional analog tone with exceptional stereo imaging. Built as a true dual-channel processor, the Dual Main EQ enhances far more than simple frequency balance. Its passive EQ network creates broad, phase-coherent curves that preserve transient detail and musical cohesion, while the all-tube gain stage restores level with the warmth, harmonic richness, and headroom expected from classic Manley designs. Custom transformer-coupled inputs and outputs add impressive low-frequency authority and analog character, making the Dual Main EQ equally at home on mix buses, mastering chains, stereo stems, or individual tracks. Updated ergonomics, Mid/Side compatibility with external matrix systems, and a universal switchmode power supply make this handcrafted California-built equalizer ready for today's most demanding professional studios.
