Description

Accuphase E-480

Overview

The Accuphase E-480 preamplifier section features the latest implementation of AAVA volume control for further enhanced clarity. Instrumentation amplifier principle in power amplification stage allows fully balanced signal transmission and realizes top-notch S/N ratio. Balanced Remote Sensing enables low impedance of output circuitry, resulting in a damping factor of 600. Power amplification stage uses power MOS-FETs in triple parallel push-pull configuration, delivering 180 watts into 8 ohms for dynamic music enjoyment.

AAVA is a revolutionary type of volume control that completely does away with any variable resistors in the signal path, using instead a  combination of 16 V-I converter amplifiers with different gain. Because the music signal is not being attenuated by a rotary resistor, optimum S/N ratio and low distortion can be maintained over the entire volume range. The signal degradation and impedance changes of conventional designs are a thing of the past. In the E-480, the V-I converter amplifiers for the highest gain stage use four parallel circuits, providing ample operation leeway and ensuring high reliability and stability.

  • Purely analog principle avoids the inherent noise of digital circuitry
  • Excellent S/N ratio at any volume level position
  • No change in sound quality over the entire range
  • Finely graded volume adjustment steps
  • No volume differences between left and right channel
  • High channel separation
  • Left/right balance adjustment and attenuation also realized with AAVA
