PROTON INTRODUCES DYNAMIC POWER ON DEMAND.
The competitive amplifier runs out of reserve capacity in 20 or 30 milliseconds; the D540 maintains reserve power for nearly half a second!
PROTON D540 -- Competitive "High Current” Amplifier
BECAUSE MUSIC DEMANDS IT.
Rated RMS Power Music is a demanding master. Nowhere does it ask more of amplifiers than in the reproduction of musical peaks. It's in this area of dynamic range that conventional amplifiers fail. They simply run out of energy before the sound does. Now, with the increased dynamics of digital audio discs and hi-fi video sound, there's more than ever to hear... or miss.
DPD lets you hear it all. Dynamic Power on Demand is a radical new design that uses two different types of circuits to supply power. The first is ideal for most of the signals that music produces. The second circuit stores power, and automatically takes over when the loudest musical passages require the big reserves; and, it provides power as long as the musical peak lasts. That's what only DPD can do deliver its reserve capacity up to 20 times longer than other amps! The result is performance that's fanatically faithful to your favorite Benatar or Beethoven.
With more realism and dynamics than you've ever heard before. But even DPD is just the beginning of our remarkable D540 integrated amp. Add to that a unique dual action volume control, phono circuitry for either moving magnet or moving coil cartridges, complete record-playback flexibility, and the ability to bridge to mono. This is the Proton D540 with DPD. The demands of music have never been better fulfilled.
