2 in stock]]> The E-3000 integrated amplifier emerged from the path forged by the technologies used in high-end equipment.
Among this amplifier’s constituent elements, the vitally important volume control circuits incorporate AAVA that
employs the ANCC principle. The power amplifier section produces balanced signals relying on the instrumentation amplifier principle while simultaneously creating a robust output stage through three-fold parallel push-pull power transistors driven in class AB. Every moment spent immersed in the vibrant playback of the E-3000 is one to relish.

  • AAVA volume control circuit

  • Powerful 100 watts into 8 ohms, 150 watts into 4 ohms

  • Three-fold parallel push-pull configuration using power transistors driven in Class AB

  • Power amplification stage configured as an instrumentation amplifier

  • High damping factor of 600

  • Balanced remote sensing to improve the damping factor

  • Current feedback amplification circuit topology assures excellent phase characteristics in the high range

  • Strong power supply with massive transformer and high-voltage, large filtering capacitors

  • Protection circuitry using MOS-FET switches

  • Tone controls using summing active filters
