Accuphase E - 202 (1974-1981)

The Accuphase E-202 is a top class Integrated Amplifier with separate component grade features and characteristics. It delivers 100 Watts per channel RMS into 8 ohms with less than 0,1% distortion from 20 to 20,000 Hz. This high power capability is backed up by heavy duty power transistors in a parallel push-pull drive output stage.
The deep reverberating sound quality and expression of music detail that is heard through an extra powerful amplifier can be far more dynamic and inspiring than sound from an ordinary amplifier. However, powerful amplifiers that may sound good at high volume levels often fail to sound as well at low listening levels.
The three position Speaker Damping Control allows one to gain the maximum performance from your speakers. The preamplifier section is loaded with features such as, Disc Low Enhancement, Subsonic Filter, Switchable Disc Impedance Selector and provision for connection of up to three tape decks with independent dubbing. The E-202 combines the best of separate components into a single unit with performance that rivals many.
