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.
Key Operational Features ::
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).
