Accuphase DAC-50 Digital Inputs

Description

Accuphase DAC-50 Digital Inputs — Convert signals from various digital source components into high-quality analog signals.

Accuphase DAC-50 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.

When the DAC input selector button or DAC input selector switch on the respective component is used to select the DAC-50 signal, the sampling frequency of the locked signal is shown on the display.

If multiple digital input signals are supplied at the same time, and OPTION is selected with the input selector, the unit automatically locks onto a signal using the following. priority sequence: COAXIAL OPTICAL USB . To exclude a signal from being selected, either disconnect the cable from the component that is not needed for playback, or turn the power switch of that component off.
