D.W. Fearn VT-9M Stereo Mastering Equalizer

Introducing the D.W. Fearn VT-9M :: a hand-crafted and built in the USA, the pinnacle of signal processing designed to elevate professional master mixes with legendary tube warmth, transparency, and PWM precision.

Pure Stereo PWM Compression pairing high-end analog control, and all-tube power for ultra-low distortion

Architectural Highlights
Pure Class-A Triode Signal Path
Utilizes eight hand-selected 6072A vacuum tubes for ultimate harmonic richness, clarity, and extended headroom without harsh artifacts.

True Stereo Operation
Two independent channels equipped with precision precision-linked gain reduction tracking to maintain flawless stereo image stability.

Advanced Pulse Width Modulator
Modern gain-control circuitry delivering ultra-smooth, musical compression dynamics across complex master stems and studio tracking.

Transformer coupled
Built with hand selected US made input bridging transformers and custom-wound output transformers optimized for modern studio integration.

• Sidechain High-Pass Filter (HPF): Features Off, Low, and High settings to eliminate heavy bass-induced "pumping" and protect low-end integrity.
• Adjustable Compression Curve ("Shape"): Seamlessly shifts behavior from gentle, transparent leveling (Softer) to assertive, tightly controlled limiting (Harder).
• True VU Metering: Conforms strictly to ASA Standard C16.5-1954, switchable to monitor Left/Right output, L+R sum, or true Gain Reduction (GR).
• True Bypass Circuitry: Allows instant, uncolored A/B comparisons with zero insertion loss when switched out.

Hand-Crafted Excellence: Not mass-produced. True Boutique Independent and US made. Each VT-9M is meticulously engineered, wired, burned-in, and rigorously tested by hand before leaving the workshop. Backed by a Limited 7-Year Warranty (90 days on vacuum tubes).

• Circuitry: Class-A triode vacuum tube audio path utilizing eight 6072A dual triodes with modern pulse-width modulation (PWM) control circuitry.
