Description
Accuphase AD-60
High-performance phono equalizer amp for playback of 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.
The AD-60 is a high-performance, MC/MM cartridge compatible phono equalizer amp for truly enjoyable playback of analog records when installed in any Accuphase preamplifier or integrated amplifier. It features the latest circuitry topology and carefully selected high-quality materials for exceptional noise suppression and superior RIAA equalization. With MC input, the most suitable impedance for the cartridge in use can be selected from 30, 100, 200 or 300 Ohms. The board also incorporates a subsonic filter to cut excessive woofer flutter caused by warped records. When installed in an amplifier with switching capabilities, the amp’s front panel controls can be used for MC/MM switching, MC input impedance selection, and turning the subsonic filter on/off. The AD-60 lets true music connoisseurs enjoy the reemerging world of playing traditional records.

The AD series Phono Equalizer unit has been newly developed. They are not just a minor update but always thoroughly pursuing the high-performance and sophisticated sound quality that goes with the times. The AD-60 is no exception; it’s dramatically improved its sound performance to fit perfectly with many Accuphase products, including the C-2300 pre-amp. The MC load setting value “200 ohms” is a newly applied, high-gained AD-60 perfectly supports from the vintage masterpiece to the state-of-the-art cartridges. The AD-60 fully reproduces the potential of Analog records and offers a beautiful discovery experience from the discs that audiophiles listen to very often.
The gain values can be set to 66dB for MC and to 40dB for MM and the MC Input impedance can be selected from 4 values for MC,“200 ohms” is newly added. They are easily switchable from the C-2300’s front sub-panel. The MM input impedance is fixed to 47k ohm.
This is a significant reduction in power consumption: 15%lower for MC and 20% lower for MM compared to AD-50.
The AD-60 has outstanding noise performance, with actual noise levels of 31.5uV for MC and 13.5uV for MM.This is the same low noise performance as the AD-50 and very close to the performance of the C-47. AD-60 switches the MC/MM setting to achieve a low noise level and RIAA equalization errors at the first stage.
MC setting: 4-Paralleled Bipolar Transistor input differentialamplifier.
MM setting: Paralleled Junction FET input differential amplifier.
