VTCSD (continued)

VTCSD “follows” the high voltage tube signal STRAIGHT INTO THE SPEAKERS, adding only current in a form of “amplifier power steering” — free from voltage gain or negative amplifier feedback!

Vaccum tubes are renowned for their high dynamic range and smooth emphasis of even-order harmonics. The transformer-less VTCSD circuit brings out hidden qualities of the vacuum tubes, including excellent frequency response, smooth “clipping” and high signal-to-noise ratio.

VTCSD divides audio signal amplification in two separate areas, voltage and current. By starting with the vacuum tube as a source of high voltage(vacuum tubes operate at four times the voltage of transistors), VTCSD adds a second solid-state “amperage amplifier.” The “amperage amplifier” is a null-gain circuit driven by “current syncs” that mirror the voltage signal and provide “torque” to the speakers in perfect synchronization with the voltage content, that neither distorts or colors the original tube sound!

The result are astonishing. All of the intensity, transience, and frequency response of the vacuum tube, which can operate at MUCH higher output voltage than audio transistors.

Benefis of Class “DE”

DE

U.S.Amps continues to push the technological envelope with the introduction of two new digital models that combine the attributes of “D” lass amplifiers with the versatility and practical fidelity usualyy expericenced only with standard Class “AB” designs. Thsi bold leap forward in digital technology allows for 90% effieciency under extreme dircumstances that turn other digital amplifiers to toast. As cars become more and more energy efficient and provide less available battery power, Class “DE” represents the best power output-to-current consumption available on the market today!
