Digital Transmission Cabling

Digital cables transmit audio and video data digitized by capturing samples of analog waveforms at distinct intervals and converting them into binary code (0s and 1s). Higher sample rates and bit depth are crucial for reproducing the music as closely as possible to the original analog source.


Content in digital form is immune to analog noise until it is converted back to analog. However, even with digital transmission, issues like collisions, jitter, and wander can occur, leading to stuttering or brief muted segments during playback.


Common Digital Cables:


Metallic AES & SPDIF: 

  • Robust, well-defined application integration and transport layer
  • Seamless latency compensation for superior playback and recording
  • Master clock and word clock easily integrated system-wide


USB: 

  • Readily available low-cost interface between streaming source and DAC.
  • Isochronous is widely used in streaming audio, fire, and forget, with no retransmission support on errored packets
  • No master clock


Ethernet:

  • High-speed access for local network attached storage
  • UDP connection to the World Wide Web for music streaming
  • Collision between multiple devices on the network can cause packet loss
