From Manley Laboratories Inc
The Manley Dual Main EQ delivers authoritative low-end weight, open and musical highs, and dimensional depth — with perfectly matched stereo operation. A passive inductor-based EQ with high-voltage tube makeup gain and custom Manley Iron transformers, built for mix-bus work, mastering chains, and high-end tracking. Handcrafted in California.
The Manley Dual Main EQ and Dual Mid Band EQ are Manley's 2026 flagship equalizers — modernized, true-stereo evolutions of two of the most respected passive EQ designs in professional audio. Built for mix-bus work, mastering chains, and high-end tracking. Individually exceptional, together unmatched.
Each unit combines a passive inductor-based EQ network, high-voltage tube makeup gain, and custom in-house wound Manley Iron transformers into a dual-channel signal path designed to do more than adjust tone. The result is equalization that shapes weight, dimension, depth, and musical cohesion — not just frequency balance.
The Dual Main EQ delivers authoritative low-end weight, open and musical highs, and dimensional depth. The Dual Mid Band EQ provides mastering-grade midrange control with smooth, musical precision — shaping presence, clarity, and punch without harshness. Together they form a complete master-bus EQ system; each equally capable as a standalone processor on sources, stems, buses, and mastering chains.
Updated ergonomics, L/R and M/S labeling, and the new Manley logo. Universal switchmode power supply — compatible with all mains voltages, contributing to the unit's extended headroom and low noise floor. Handbuilt in California.
