Hazelrigg Industries DVA 500 PRE

The DVA from Hazelrigg Industries delivers the unmistakable warmth and musicality of classic tube preamps in a compact 500 Series format. Drawing from the renowned D.W. Fearn VT-2 and Hazelrigg VLC designs, the DVA features a 6072a vacuum tube input stage with transformer-balanced input and output, capturing every nuance of your source with exceptional clarity and depth.

To suit the 500 Series' power limitations, makeup gain is handled by a low-THD solid-state amplifier, delivering up to 60 dB of gain with minimal coloration. Whether used with microphones or instruments, the DVA offers smooth, harmonically rich tone, enhanced by thoughtful features like phantom power, polarity reversal, -20 dB pad, high-pass filter, and an output level indicator. It's an ideal choice for engineers seeking the refined sonics of boutique tube gear in a portable and efficient format.
