BALANCED AUDIO TECHNOLOGY VK-33 Preamplifier
NEW POWER-SUPPLY TRANSFORMERS FOR INCREASED SPEED, DYNAMICS
BAT's VK-33 preamplifier incorporates changes to its power supply formerly reserved for Special Edition models. New SE power-supply transformers provide marked increases in dynamics and speed. In addition, the signal in the VK-33 is transmitted through only one gain stage. As such, it’s free from the negative artifacts attributable to both extremes of modern preamplifier designs: passive preamplifiers at one end of the spectrum and multistage, buffered active circuits at the other. The UnistageTM circuit provides the ultimate simplicity of amplifying the incoming signal only once, using no global feedback to double-back on the straight-through signal integrity.
BALANCED IS BETTER
Naturally, the VK-33 is balanced. Why is this approach superior? Balanced topology simply provides a complete signal representation. Magic happens when you free yourself from limitations of the single-ended structure with its half-signal processing. If a craftsman with one hand tied behind his back can be very good, imagine what he can be with two hands. Vacuum-tube current sources further improve the linearity of the gain stage to yield a more open, textured sound. In addition, with the purchase of BAT’s X-PAK accessory, more than one type of vacuum tube can be used, meaning you can fine-tune the sound to best meet your individual needs.
YOU’LL ALWAYS GET THE VOLUME EXACTLY HOW YOU WANT IT
Outfitted with a superior user interface, the VK-33 preamplifier is a breeze to use right out of the box. BAT also took care of vinyl lovers. Just order the VK-33 with BAT’s VK-P3 phono card, which provides switch-selectable moving-magnet and moving-coil gain settings. And with the VK-33, you can always get the volume just right. It employs a proprietary electronic shunt volume attenuator that offers 140 steps of 0.5dB resolution that sound continuous to the human hear. Discrete metal film resistors are used to bleed the unused signal to ground. Indeed, all you need to do is listen.
