BALANCED AUDIO TECHNOLOGY VK-33SE Preamplifier
UNCOMMONLY GOOD TRANSFORMER DESIGN
With its new transformer-coupled outputs and superb user interface, the VK-33SE offers both extremely dynamic, transparent renditions of musical events and the industry’s best ease-of-use versatility. The result of intense research, each of the preamplifier’s transformer-coupled outputs is encapsulated within a mu-metal shield, a design substantially superior to any capacitor in maintaining purity of signal transmission. True to its heritage, the VK-33SE uses the 6H30 SuperTube to form a high-current, low-impedance gain stage. For extra convenience, the fully balanced VK-33SE even incorporates a mix of balanced and single-ended inputs as well as outputs.
NEVER FRET ABOUT VOLUME LEVELS AGAIN
Effectively, the signal in the VK-33SE preamplifier is transmitted through only one gain stage. This UnistageTM circuit provides the ultimate simplicity of amplifying the incoming signal only once and uses no global feedback to double-back on the straight-through integrity of said signal. Pass music through too many gain stages, and you’ll no longer recognize the genius and beauty of your favorite recordings. And with the VK-33SE, you can always get the volume just right. A proprietary electronic shunt volume attenuator offers 140 steps of 0.5dB resolution that give precise, repeatable volume settings that sound continuous to the human ear.
UNPARALLELED INTERFACE AND OPTIONS
The VK-33SE is easy to use right out of the box. You can dim the display from the comfort of your chair by using the BAT remote. Fade music at the touch of a button. Switch phase to see if a recording is made in reverse absolute polarity. Even name your sources. For example, name your home-theater playback input “THTR.” Then, fix the volume for your THTR input to control your home-theater system from your pre/pro remote. Analog lovers are also in luck. Simply order the VK-33SE with Balanced Audio Technology’s VK-P3 phono card, which provides switch-selectable moving-magnet and moving-coil gain settings.
