Accuphase DAC-60 Accuphase DAC-60 is an optional digital input board that supports a broad range of digital sound sources and is equipped with a high-precision MDS type D/A converter for optimal sound quality. The converter uses AK4490EQ chips from Asahi Kasei Microdevices in a double parallel configuration per channel. Installing the board in a slot on the rear panel of a supported Accuphase component provides direct input capability for signals from digital components for high-grade playback. Three types of inputs are provided: USB (Type B), OPTICAL (for optical fiber cable), and COAXIAL (for coaxial cable). The USB input handles signals up to 11.2 MHz / 1-bit 【DSD】 and 384 kHz / 32-bit【 PCM】, the coaxial input supports up to 192 kHz / 24-bit and the optical input up to 96 kHz / 24-bit Function An automatic change of the coax input / optical fiber /USB input Automatic recognition of number of sampling frequency /bit /MHz de-emphasis Guaranteed specifications USB ：USB 2.0 High Speed （480Mbps） compliant ：Sampling frequency DSD/2.8224MHz,5.6448MHz,11.2896MHz(1bit) *11.2896MHz(ASIO only) ：PCM/ 32kHz～384kHz,32bit OPTICAL：JEITA CP-1212 compliant ：Sampling frequency 32kHz～96kHz, 24bit COAXIAL：IEC 60958/AES-3 compliant ：Sampling frequency 32kHz～192kHz, 24bit About sampling frequency displaywhen DAC-50 is installed in C-2120, E-600, E-470, E-370, or E-270Sampling 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 reproduction of music data by the USB depends on OS on the PC and softwareof music reproduction. * Please refer to the manual of the PC for setting and the connection method of the PC about USB. Supplied accessories USB Utility CD-ROM Connection * If multiple input signals are supplied at the sametime, the unit automatically locks onto a signal when"OPTION 1" is selected, using the following priority sequence: COAXIAL → OPTICAL → USB * To exclude a signal from being selected, either disconnect the cable or turn power of the respective equipment off.
