The DAC‐51 Digital to Analog Audio Decoder uses 24‐bit audio DSP and 192KHz DACs to convert virtually any type of digital audio input to stereo output.
It supports uncompressed two‐channel PCM as well as compressed multi‐channel bit‐stream audio (such as 5.1 channel audio) and provides two channels of analog outputs both on RCA as well as 3.5mm headphone jack. When the input is multi‐channel, the device down‐mixes (using downmixing or fold‐down algorithm) the digital channels to 2‐channel stereo for easy connection to entertainment devices. When the input audio is multichannel the unit intelligently combines Left Front, Left Rear, Right Front, Right Rear, Center, and Subwoofer (LFE) in a way to create two channel stereo output.
Both TOSLINK optical, coaxial digital SPDIF inputs are provided. The user can select which input to use via a slide switch on the box
