Blustream CAT100AU Digital Audio Over CAT


The CAT100AU Audio over CAT5e/6 extender kit transmits audio signals up to a distance of 300m (192kHz signals up to 100m).
This plug-and-play device accepts both optical and coaxial digital inputs and includes a built in DAC to enable use of the stereo left / right audio output from either input.



  • Extend optical and coaxial digital audio signals up to distances of 300m* over a single CAT cable
  • Both optical and coaxial digital can be distributed at the same time
  • Built in DAC (Digital to Analogue audio Converter) converts either optical or coaxial digital (selectable) to analogue stereo left/right audio output (source selected on receiver unit)
  • Supports sample rates 32kHz, 44.1kHz, 48kHz, 96kHz and 192kHz up to 24-bit resolution
  • Ultra low jitter and high fidelity design

*CAT100AU supports distances of up to: 192kHz – 100m; 96kHz – 150m; < 48kHz – 300m
