DVA Preamp / DI (500 Series)

500 Series Module

From Hazelrigg Industries:

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/high output 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.
