VDP Dual Preamp / DI
Microphone Preamplifier
From Hazelrigg Industries:
VDP is a handcrafted, two-channel preamp and DI featuring an all-tube signal path and transformer-coupled input and output stage, adding natural harmonic depth and musicality. Drawing from the acclaimed preamp and power design of the D.W. Fearn VT series, VDP brings the character and richness of the classic, paired with cleaner output, lower noise, and modern high-end polish.
Definitive Input Stage: An intuitive front end with a world-class tube stage to enhance any source and to complement all microphones. Designed for higher gain, the VDP introduces a nuanced shine unique to the DWF Hazelrigg lineup.
Clean gain for ribbons, articulate for condensers, and deep headroom for your loudest dynamics.
