Introducing The Hazelrigg Industries D Series Modules

New from Hazelrigg Industries, the D Series of 500 Series modules deliver the tone, clarity, and musical control that you’ve come to expect, presented in a portable, cost-effective package.

Hazzelrig modules include the DVA Vacuum Tube Microphone Preamplifier/DI, DLC Vacuum Tube Inductor Equalizer, and DNE Pulse Width Modulation Compressor.

DVA Vacuum Tube Microphone Preamplifier/DI

The DVA is a hybrid microphone preamplifier based on the Hazelrigg Industries VLC and D.W. Fearn VT-2 preamp. Utilizing a single 6072a vacuum tube, the input circuitry matches the VLC/VT-2 input stage exactly and features transformers in both the input and output stages. Make-up gain is provided by a low-THD/highoutput solid state signal path (as opposed to the vacuum tube circuits in the VLC/VT-2) due to the module size and power supply limitations inherent in the 500 series format. Total gain available is approximately 60db.

DLC Vacuum Tube Inductor Equalizer

The DLC is based on the passive equalizer circuit in the Hazelrigg Industries VLC (originally found in the D.W. Fearn VT-5). It shares the same filter capacitors and handwound inductor as the VLC, though the audio path is slightly different. The input audio circuit comes from the D.W. Fearn VT-2, while the output uses a low THD/high gain solid state amplifier design. Like the VLC, the DLC uses transformers in both input and output stages.

DNE Pulse Width Modulation Compressor

The DNE gets its compression circuitry directly from the Hazelrigg Industries VNE and D.W. Fearn VT-7. Attack and release times have been optimized to simplify the user interface. The HPF makes the compressor less reactive to low frequencies (for example, bass and kick). Linking units require 500 series racks with a link option. Signal path utilizes input and output transformers and low-THD/high-gain solid state devices. Gain reduction is shown with LEDs.
