The Balanced Audio Technology VK-3 offers an unmatched combination of
performance and value in a fully balanced line stage. This six-tube zero-feedback
design features vacuum-tube current regulation, continuously adjustable shunt
volume control, custom encapsulated oil-filled signal capacitors, and the
same Unistage™ circuit topology used throughout the BAT series of line stage
preamplifiers.
Balanced design
The VK-3 is a fully balanced design from input to output. Competing units
often simply add XLR jacks to a single-ended internal circuit. The benefits of
fully differential signal handling are lost in such designs. The VK-3’s purist
approach to balanced signal transmission preserves the performance benefits of
truly balanced source components and power amplifiers. At the same time,
the VK-3 is completely compatible with single-ended systems via BAT’s highquality plug-in adapters.
Sonic purity
The VK-3’s Unistage™ design employs a single gain stage to amplify the signal.
The stage-to-stage coupling distortions inherent in complex buffer or follower
circuits are eliminated altogether. This single-stage design works together
with the VK-3’s shunt volume control and custom encapsulated oil-filled signal
capacitors to convey the pace, excitement, and nuance of a fine recording.
Remarkable value
Excellence in engineering reflects the ability to attain ever-higher performance
at a given price. In this regard, the Balanced Audio Technology VK-3 represents
the highest standard of design achievement. The VK-3’s fully balanced design
is a demanding union of purist circuit topology, vacuum tube current regulation,
and premium parts selection that offers a sound previously unavailable at
this price.
Emotional involvement
Whether used with solid-state or vacuum-tube power amplifiers, balanced or
single-ended sources, digital or analog recordings, the VK-3 imparts a special
magic to the reproduction of music. It provides a direct emotional connection to
the performance. Whatever your system, we encourage you to visit your BAT
audio specialist and experience this magic for yourself.
