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.

• 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
