Accuphase DAC-60 Digital Input Board

Accuphase DAC-60 Digital Input Board

The DAC-60 is a digital input board that can input digital signals directly into amplifier units when installed in Accuphase preamplifiers and integrated amplifiers (listed below). Three input types are provided (USB, OPTICAL, COAXIAL) for connection to a broad range of digital devices. The D/A converter adopts the “2MDS+ (Multiple Delta Sigma) converter principle” with ES9016K2M (ESS Technologies) mounted in parallel to convert analogue signals that remain extremely true to the original source sound. Born from cutting-edge audio technologies, the DAC-60 is an option board that provides truly high quality and fully expressive performances.

Function

• An automatic change of the coax input / optical fibre / USB input
• Automatic recognition of number of sampling frequency /bit /MHz de-emphasis

When DAC-60 is installed in C-2120, E-600, E-470, E-370, or E-270:

• Sampling frequencies up to 192 kHz are shown as is.
• Signals with the following sampling frequencies are handled without problem, but the indication is always "192.0 kHz":
  【DSD】 2.8224 MHz, 5.6448 MHz, 11.2896 MHz
  【PCM】 352.8 kHz – 384 kHz

* The capability for playback of music data via a USB connection depends on the operating system and music playback software of the computer.
