Specifications

Convert digital signals into high-quality analog signals

The 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, and Coaxial. 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. If multiple input signals are supplied at the same time, 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.
