Description

This dual-channel passive tube equalizer delivers broad, natural tone shaping for tracking, instrument buses, mix buses, stem processing, and mastering. Its inductor-based networks support simultaneous boost and cut, allowing subtle perspective changes or substantial tonal moves while preserving depth, transient character, and musical continuity.

An all-tube makeup gain stage restores the level lost through passive equalization, adding harmonic dimension, density, and authority. Matched stereo channels support Left/Right and external Mid/Side workflows, while custom input and output iron transformers, illuminated controls, and a universal switch-mode power supply provide a refined studio experience.

Features

Natural Passive Equalization
Broad, phase-coherent curves provide smooth tonal shaping that remains connected to the original source.

Simultaneous Boost and Cut
Overlapping boost and cut controls offer flexible shaping with subtle or pronounced results.

All-Tube Signal Path
Tube-based makeup gain adds harmonic dimension, depth, and authority after the passive EQ stage.

Custom Iron Transformers
Input and output transformers contribute density, low-frequency weight, and a dimensional sound.

Precision Stereo Operation
Matched dual-channel architecture supports stereo processing across tracking, mixing, and mastering workflows.

Mid/Side Compatibility
The dual-channel layout integrates with external Mid/Side matrices for precise spatial control.

Classic Low-Shelf Character
Smooth low-frequency shaping adds fullness, weight, and definition.

Open High-Frequency Response
Natural top-end shaping provides clarity and air while retaining musical character.

Refined Controls
Illuminated controls and satisfying mechanical operation support clear, confident adjustments.
