DVA Vacuum Tube Microphone Preamplifier/DI: A Blend of Vintage Warmth and Modern Precision
The DVA Vacuum Tube Microphone Preamplifier/DI by Hazelrigg Industries is a premium hybrid preamp that combines the best elements of the classic Hazelrigg VLC and the D.W. Fearn VT-2. Designed with a single 6072a vacuum tube, the DVA captures the iconic sound of tube-based preamps while integrating a high-output, low-distortion solid-state signal path, making it a versatile addition to any 500 series rack.
A Perfect Fusion of Analog Warmth and Solid-State Clarity
The DVA’s design incorporates the VLC/VT-2 input stage, utilizing transformers in both the input and output stages for a rich, full-bodied tone. Unlike traditional vacuum tube circuits, the DVA achieves make-up gain through a solid-state output stage, which allows for low total harmonic distortion (THD) and high output capabilities, an essential feature for the compact 500 series format.
Key Features and Specifications
The DVA is packed with features that make it a powerful tool for both recording and live performance:

- Vacuum Tube DI (6072a): Ideal for instruments, this DI offers a lush, natural tone that enhances any input.
- Transformers in Input and Output: Designed for rich harmonic content and optimal impedance matching.
- Total Gain of 60dB: Offers ample headroom for a variety of microphones and instruments, ensuring versatility across applications.
- Polarity Reversal Switch: Allows for easy phase alignment during recording sessions.
- -20dB Pad Switch: Enables attenuation of hot signals, perfect for high-output microphones and instruments.
- +48V Phantom Power with LED Indicator: Supports condenser microphones and active DIs with a convenient on/off LED indicator.
- High Pass Filter Switch: Filters out unwanted low frequencies, reducing rumble and handling noise.
User Tips for Optimal Performance
The DVA’s high output and classic tube character make it a flexible choice, but there are a few user tips to keep in mind:
- Handling High-Output Condensers: Many condenser mics have high output levels, which may overload the DVA’s input transformer. If you experience clipping, engage the mic’s pad if available.
- Exploring Tube Saturation: For a more saturated tone, engage the -20dB pad and send an attenuated signal to the DVA. You can then increase the gain to adjust the tone and saturation level to taste.
Built to Last with Professional-Grade Components
The DVA boasts the reliability and craftsmanship Hazelrigg Industries is known for. It features premium transformers, a rugged front panel microphone/instrument input, and an output level indicator LED. This preamp/DI is hand-built to ensure each unit meets stringent quality standards.
