Description
Accuphase AD-50
High- performance phono equalizer amp for playback of analog records.
- MC/MM switching is possible on the front panel of the enabled device.
- Internal DIP switches control MC input impedance and subsonic filter on/off.

With the release of E-650, Accuphase renews the dedicated Analog Disc Input Board AD-50 to expand the optional capabilities.
The Accuphase AD-50 is the 5th generation dedicated Analog Disc Input Board.
The greatest technical feature is ultra low noise performance close to the Phono EQ amp C-37.
AD-50 shows the ultra low noise performance.Its output noise voltage is 12% lower than the former model AD-30 at MC setting.
AD-50 switches MC/MM setting at first stage to achieve the Ultra low noise performance.
MC setting: Paralleled Bipolar Transistor input differential amplifierMM setting: Paralleled Junction FET input differential amplifier.
AD-50 has the wide backward compatibility, it can be used with not only the current models but lots of legendary amplifiers.
