D.W. Fearn VDP Two-Channel Tube Microphone Preamp and DI

For recording engineers seeking depth, dimension and control at the front end of the signal chain, the D.W. Fearn Hazelrigg VDP two-channel tube microphone preamp and DI delivers classic tube tone with modern precision. Handbuilt in the USA and rooted in the legacy of the D.W. Fearn VT series, this two-channel tube mic preamp features an all-tube signal path with transformer-coupled input and output stages, shaping tone with natural harmonic richness and a refined, musical response. With up to +63dB of gain, expanded headroom and improved noise performance, it handles everything from gain-hungry ribbon microphones to high-SPL sources with clarity and control. Whether you’re tracking vocals, instruments or direct sources, the VDP brings a polished, dimensional character to any professional recording environment.

All-Tube Signal Path With Transformer-Coupled Depth

The VDP’s fully tube-driven architecture is designed to enhance—not mask—the source, delivering the harmonic complexity and dimensionality that define high-end studio preamps. Transformer-coupled input and output stages provide isolation and subtle saturation, adding weight to low frequencies, smoothing transients and introducing a natural sense of depth across the stereo field. Drawing from the design philosophy of the D.W. Fearn VT series, this circuit balances vintage character with modern stability, giving engineers a reliable front end that translates across microphones, instruments and full mixes.

High-Gain Input Stage With Controlled Saturation and Headroom

With up to +63dB of available gain, the VDP is built for precise gain staging across a wide range of sources. It delivers clean, open amplification for ribbon microphones, maintains transient detail with condensers and preserves clarity when capturing loud dynamic sources. When pushed, the tube stage introduces a controlled, musical saturation that enhances presence and density without collapsing the signal. This flexibility allows engineers to move seamlessly between transparent capture and tonal shaping, making the VDP equally effective for critical tracking and character-driven recording.

Front-End Control and Flexible Studio Integration

Designed for modern recording workflows, the VDP combines intuitive front-panel control with flexible routing options. Front-mounted Mic and DI inputs support quick instrument tracking, while rear XLR connections integrate easily into permanent studio setups. A high-pass filter and -20dB pad provide essential gain-stage management before the signal reaches converters, and a polarity reversal switch ensures proper phase alignment in multi-mic applications. The locking +48V phantom power switch—borrowed from aircraft-style safety design—adds confidence when working with sensitive microphones in professional studio environments.

Handbuilt Tube Preamp for Professional Recording Chains

Every unit is handcrafted in the United States, combining carefully selected low-noise 6072A and 12AT7 tubes with a fully regulated power supply for consistent, reliable performance. The result is a studio preamp that delivers both sonic character and operational stability across long sessions and demanding tracking environments. For engineers, producers and serious home studios seeking a two-channel tube microphone preamp and DI that balances vintage-inspired tone with modern headroom, control and integration, the D.W. Fearn Hazelrigg VDP Two-Channel Tube Microphone Preamp and DI stands as a refined front-end solution for today’s recording workflows.
