Dynamic Super-A
Dynamic Super-A: For low-distortion performance throughout the audible frequency range. Dynamic Super-A is a refinement of our revolutionary Super-A, the design that offers the distortion-free sound of a class-A amp, and the efficiency of a class-B amp. Popular class-B amps offer high efficiency, but they achieve it by switching the output transistors on and off. This results in an increase in distortion - switching distortion. Unrelated harmonically with music, switching distortion adds a harsh, metallic or gritty quality to the sound you hear. The alternative is the class-A amp which offers smooth low-distortion switchless sound, yet it requires its output transistors to be always on. This means low efficiency, bulky size and high cost. JVC Super-A is the answer to this dilema - it combines the positive aspects of both class-A and class-B amps. It does not generate switching distortion (like class-B amps). It gives sound a smooth, yet powerful quality. Dynamic Super-A was developed with the singular purpose of catching up with vast improvements that have recently been made in the dynamic range of new digital technologies.
Gm Circuit
The integrated amplifier in our lineup features our new Gm Circuits. The Gm Circuit is essentially a noise reducer. Its electronic circuit design converts voltage into current for amplification, then reconverts the amplified current back into voltage. This unique new process is best understood when you consider that a transistor is inherently a current amplifying device, even though it is usually used for voltage amplification. It is thus apparent that when we use transistors in the manner in which they perform best - as current amplifiers - a tremendous improvement in actual performance is possible.
