E-480 Integrated Amplifier
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.
