VT-1 &

VT-2 Microphone Preamplifers

DESCRIPTION

The Model VT

-1 and VT-2 Vacuum Tube Microphone Preamplifiers are designed to provide

ecor

ding professionals with a sonically superior input device. (Unless there is a specific rea-

son to address a difference between the VT-1 and VT-2 preamplifiers, the device will be

referred to as the “VT-2.”) It is typically used in sound recording studios for recording indi-

vidual tracks. A quality microphone is connected to a VT-2 input, and the VT-2 provides a

line-level output. In most situations, the VT-2 will feed directly to the input of the recorder.

The VT

-2 is a recreation of the classic tube preamps of the 1960s, updated with improved

moder

n passive components and computer-aided circuit optimization. Because of the unique

qualities of vacuum tubes, the VT-2 has a clarity, transparency, and warmth that solid state

preamps lack. Its modern design and construction allows the VT-2 to exceed the per-

mance of vintage vacuum tube preamps.

It is designed f

or use in the professional recording environment. It accepts all low impedance

balanced micr

ophones. It f

eatures a regulated +48 volt supply for phantom powering con-

denser microphones, a switchable 20 dB input pad, a phase (polarity) reversal switch, a

switchable in

put network to accommodate very low impedance microphones (typically trans-

formerless types), and a true VU meter. It is built to sound great for a long time, with top qual-

ity par

ts used throughout; all the transformers and many other components are custom-made

or t

he VT-2.

All f

our power supplies (filament, phantom power, B+, and meter amp) are solid state and

fully regulated. The Attenuation control potentiometer is a conductive plastic type for long,

noise-free operation.

The VT-2 is not mass-produced. Each one is hand-made and meticulously tested and listened

to bef

ore shipment to the customer.
