The D.W. Fearn model VT-I/F Vacuum Tube Instrument Interface is designed to
provide recording professionals with a sonically superior method for recording
electric and electronic musical instruments by direct injection (DI). Any instru-
ment designed to operate into a “guitar amp” will work perfectly with the VT-I/F.
Typical instruments include: electric bass, electric guitar, electric piano, acoustic
instruments with a pickup (piano, acoustic guitar, electric violin, etc.), synthesiz-
ers, and samplers.
The VT-I/F is a two-channel device that provides the optimum load impedance
for these instruments. It is capable of quality reproduction of a wide range of
instrument levels. The unit does not have the limitations of passive transformer-
type DIs, and has greater headroom and warmth when compared to similar solid-
state devices.
It is designed to operate in the professional recording or performing environ-
ment. The output level is “hot” mic level (-30 dBm nominal). The output is trans-
former-balanced, using a custom transformer built for us by Jensen Transformers,
Inc., and is designed to match 150 ohm professional mic inputs. Top-quality parts
are used throughout. The case is machined from solid quarter-inch thick aluminum
plate for ruggedness and durability. Both the filament and plate power supplies are
fully regulated.
The VT-I/F is not mass-produced. Each one is hand-made and meticulously test-
ed before shipment to the customer.
