1 Introduction 1.1 Highlights
The eRED-DOCK interface offers a top-notch solution for network audio playback systems, based on our Ethernet Audio Renderer Module eRED-MOD. Developed exclusively for High-End systems, it achieves jitter- free, bit-perfect playback with no compromise on sound quality. Thanks to its compatibility with the UPnP AV 2.0 standards, its integration into a home network is easy. Key features for the eRED-DOCK include:
• Digital Media Renderer for stereo audio
• UPnP AV 2.0 / DLNA
• Playing and decoding common audio formats* from HTTP streams
• 2-channel asynchronous endpoint for highest quality digital audio stereo playback
• Bit-perfect jitter free data transmission
• Up to 32-bit resolution, sampling rate up to 384 kHz
• Support for DSD64, DSD128 and DSD256
• Support for gapless playback
• On-board 22.5792 MHz and 24.576 MHz ultra-low phase noise oscillators.
• Master clock output for DAC synchronisation
• I2S/DSD output at CMOS level
• S/PDIF and AES/EBU digital audio outputs, buffered and transformer-coupled
• Single 5V power supply
