D.W. Fearn VT-4 Vacuum Tube LC Equalizer 15

DESCRIPTION

The Model VT-4 Vacuum Tube LC Equalizer is designed to provide recording professionals with a son-

ically superior outboard processing device. It is typically used in sound recording studios for modify-

ing the frequency response characterisics of an individual track. A pair of VT-4s can be used to

process a stereo mix with precise matching between units.

It is designed for use in the professional recording environment. It accepts all standard low-impedance

(nominally 600 ohm) line-level (nominally +4 dBm) signals. The output is line-level (+4 dBm) low-

impedance, transformer-isolated and designed to feed bridging inputs. It is built to sound great for a

long time, with top quality parts used throughout; all the transformers, inductors and many other com-

ponents are custom-made for the VT-4.

All power supplies are solid state and fully regulated. All rotary controls use high-quality silver-contact

switches for precise repeatability and matching between units.

Much of the circuitry for the VT-4 is based on the highly-successful D.W. Fearn VT-1 and VT-2 Vacuum

Tube Microphone Preamplifiers. Since line-level signals are utilized in the VT-4, Class-A Svetlana

6N1P dual triodes are used for all amplifier stages. The input transformer, inductors in the passive

equalization circuitry, and the output transformer are custom-made for us by Jensen Transformers

Inc.

The VT-4 is not mass-produced. Each one is hand-made and meticulously tested and listened to before

shipment to the customer.

The philosophy behind the VT-4 is: use only the best components in an optimized circuit, and build it

with pride and precision. The VT-4 is designed and built to perform in your studio for decades to come.
