Hazelrigg Industries DNE The Hazelrigg Industries DNE is a high-end PWM compressor in API 500 format, bringing the classic D.W. Fearn compression design into a compact module. As part of the Hazelrigg D Series, it is directly derived from the renowned VNE and VT-7 circuits. It uses pulse width modulation (PWM), enabling extremely fast attack and release times with highly accurate and low-distortion compression. The combination of transformers and clean solid-state circuitry ensures both precision and musicality. The interface is intentionally simplified: instead of continuous controls, optimized fast/slow switches for attack and release allow quick and effective adjustments—ideal for fast-paced studio workflows. Sound Character The DNE delivers fast, transparent, and highly controlled compression with minimal coloration. It excels at catching transients without altering the natural tone of the signal. Thanks to its PWM design, it is particularly effective for peak control and “invisible compression,” especially on vocals and dynamic sources. It can also provide punchier results when driven harder. The built-in sidechain high-pass filter ensures that low frequencies do not trigger excessive compression, preserving a tight and controlled low end.

Hazelrigg Industries DVA The Hazelrigg Industries DVA is a high-end hybrid tube microphone preamp and DI in API 500 format, bringing classic D.W. Fearn circuit design into a compact module. As part of the Hazelrigg D Series, it is directly inspired by the renowned VLC and VT-2 designs. At its core is a 6072A vacuum tube input stage combined with a clean, high-output solid-state gain stage. This hybrid design delivers classic tube warmth along with modern clarity, low distortion, and high headroom—optimized for the 500-series format. Transformer-balanced input and output stages further enhance harmonic richness and musicality, while practical features like pad, high-pass filter, and phantom power make it a versatile recording tool. Sound Character The DVA delivers a large, open, and highly musical sound with excellent depth and presence. Like high-end tube preamps, it makes sources feel bigger and more dimensional without sacrificing clarity. The tube stage adds harmonic richness and subtle compression, while the solid-state output ensures stability and precision. The result is a balance of vintage warmth and modern transparency. By driving the input stage (e.g. using pad and gain), users can shape the tone from clean and detailed to saturated and characterful.

Hazelrigg Industries VDI The Hazelrigg Industries VDI is a high-end all-tube direct injection box designed for professional studio and live applications. Based on the legendary D.W. Fearn VT-1/F circuit, it brings classic tube tone into a compact and portable format. At its core is an all-triode vacuum tube signal path with extremely high input impedance, ensuring accurate capture of instrument signals such as bass, guitar, and synthesizers. The output is transformer-balanced for optimal signal integrity. The interface is intentionally simple: a 1/4" instrument input, a thru output for amplifier routing, and a balanced XLR output for connection to a microphone preamp. Sound Character The VDI delivers a warm, rich, and highly musical sound with excellent clarity and depth. The tube circuitry adds harmonic richness and subtle compression while preserving detail. Its high headroom ensures stable, open, and dynamic performance even with demanding sources. It is particularly effective on bass, acoustic instruments, and synthesizers, offering both subtle enhancement and characterful coloration. Highlights ✔ high-end all-tube DI box ✔ based on D.W.
