Country of Origin:

The E-380 realizes a 20% increase in rated output power thanks to a reinforced power amplification stage and power supply. The further evolved AAVA volume control system allows music enjoyment at any level without even the slightest degradation of signal quality. The power amplifier section utilizes the instrumentation amplifier principle to achieve an outstanding S/N ratio. The low impedance design of the output circuitry results in a damping factor of 500, ensuring that the potential of every speaker can be brought out to the fullest. Enjoy a musical performance of amazing transparency and dynamism.

Warranty:

1-year manufacturer's warranty

Features:

  • AAVA volume control
  • Power amplification stage with bipolar transistors in double parallel push-pull configuration
  • Rated for 180 watts into 4 ohms and 120 watts into 8 ohms
  • The high damping factor of 500
  • Power amplification stage configured as an instrumentation amplifier
  • Current feedback amplification topology in the power amplification stage
  • Logic-control relays for shortest signal paths
  • Strong power supply with massive high-efficiency transformer and large filtering capacitors
  • Protection circuitry using MOS-FET switches

Power supply circuitry designed for optimum stability
The large transformer and massive 33,000 μF filtering capacitors with 10% more capacitance provide rock-stable high-quality power

Power amplification stage with bipolar transistors
The power amplification stage features bipolar transistors in a double parallel push-pull configuration.

Option Boards
The rear panel expansion slot allows for use of one of the available AD-30 (phono preamplifier) or DAC-40 (digital to analog converter) option boards.
