4 Power Amp

4.1 Dynavalve™ Technology

Seasoned players know the deal: 100 tube-driven watts simply sound louder than 100 solid state-powered watts. The reason for this is that tube power amps’ complex dynamic properties enhance audio signals with transients. These added frequencies enrich the spectrum, making each note sound more concise, more explosive, and louder. In other words, our perception of volume is shaped not only by pure output power; the content of the signal is equally important. Though the musical qualities of tube-driven power amps are heartwarming, their weight-related drawbacks are back- breaking and budget-busting. Due to the nature of tube designs, they are bigger, heavier, more expensive and more sensitive than their solid state kin. The ideal solution would be a solid state power amp with the dynamic, frequency-enriching qualities of tube circuitry. And that’s exactly what Dynavalve™ technology is all about.

It is the product of many years spent researching tube power amps’ tone-shaping processes. Rather than coloring the sound of a solid state amp, the Dynavalve™ circuit "forces" the amp to behave just like its tube-driven counterpart. The result: In comparison to con- ventional solid state power amps with the same power ratings, Dynavalve™ yields far better tone, much more sound pressure and greater punch! In a nutshell, Dynavalve™ delivers truckloads of tone, satisfying the demands of even the hardest-core tube fanatic.

4.2 Handling:

Master:

Though the MASTER knob determines the amp’s overall level, it is more than merely a volume knob. In combination with the GAIN knob, it lets you dial in subtle tonal variations to shape a vast spectrum of sound ranging from squeaky clean to true grit.
