Accuphase E-380 Integrated Amplifier

The preamplifier section is equipped with a unique volume control technology "AAVA" that does not use a variable resistor. The power amplifier section uses an "instrumentation amplifier" that balances the signal path from the input terminal to the output stage. The power amplifier section uses a current feedback amplifier circuit that has excellent high-frequency transfer characteristics and feeds back the output signal with current, achieving low impedance in the feedback circuit. The power amplifier stage uses two parallel push-pull configurations of NPN and PNP "bipolar transistors", and the elements are mounted on a large heat sink for efficient heat dissipation. In addition, the power amplifier stage and power supply section have been strengthened to ensure an output of 120W x 2 (8Ω) and 180W x 2 (4Ω). The protection circuit uses a MOSFET switch with a very large rated current of 160A and a very low ON resistance of 0.002Ω, solving the problem of aging and ensuring long-term reliability. Equipped with two slots for adding optional boards. ■Rated continuous average output: 180W/ch (4Ω), 120W/ch (8Ω)
