Blustream CAT100AU CAT6 Audio Extender up to 300m
Digital audio extender kit for coaxial and optical connection, through CAT5e/6 cable up to 300m. Allows the use of stereo audio output
Audio extension kit over CAT5e/6 cable. Allows the transmission of audio signals up to a distance of 300m. This plug-and-play device accepts both optical and coaxial digital inputs and includes an integrated DAC to allow the use of the left/right stereo audio output of either input. It supports distances up to: 192kHz - 100m, 96kHz - 150m, < 48kHz - 300m.
Audio extender kit over CAT5e/6 Blustream CAT100AU features
- Extend optical and coaxial digital audio signals up to distances of 300m over a single CAT cable (192kHz - 100m, 96kHz - 150m, < 48kHz - 300m)
- 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

FAQs about the Blustream CAT100AU
1.- What is the main function of the Blustream CAT100AU?
It is an extender kit (TX Transmitter and RX Receiver) designed to transmit digital audio signals (optical and coaxial) over long distances (up to 300 meters) using a single CAT5e/6 network cable.
2.- What types of audio inputs does the transmitter unit (TX) support?
The CAT100AU-TX module (Transmitter) accepts two types of digital audio signals: one Optical (S/PDIF) input and one Coaxial (S/PDIF/RCA) input. It can simultaneously distribute the digital audio from both sources.
3.- What audio outputs does the receiver unit (RX) offer?
The CAT100AU-RX module (Receiver) provides three types of audio outputs: Optical (S/PDIF), Coaxial (S/PDIF/RCA), and an analogue stereo L/R output (3.5mm jack).
4.- What is the maximum transmission distance and how does it depend on audio quality?
The maximum distance varies depending on the sample rate:
- 300 meters for sample rates below 48kHz.
- 150 meters for 96kHz.
- 100 meters for 192kHz.
The CAT100AU supports resolutions up to 24-bit.
5.- Does the equipment include Digital to Analogue Conversion (DAC) functionality?
Yes. The receiver unit (CAT100AU-RX) features a built-in DAC (Digital to Analogue Converter) that allows it to take the digital signal (optical or coaxial, selectable) and convert it to the analogue stereo L/R 3.5mm audio output.
6.- How is the equipment powered and what is PoC (Power over Cable)?
The equipment is powered by a 5V/1A DC power supply connected only to the receiver unit (RX). The system is compatible with PoC (Power over Cable), meaning the Receiver powers the Transmitter over the CAT cable itself. This simplifies installation by only requiring one power point.
7.- Is any software or driver required for operation?
No. The Blustream CAT100AU is a "Plug-and-play" device. No additional software or drivers are required for installation and operation.
8.- What digital audio formats are supported?
It supports sample rates from 32kHz, 44.1kHz, 48kHz, 96kHz up to 192kHz with up to 24-bit resolution. The design is optimized for high fidelity and ultra-low jitter.
9.- Can I use the kit to simultaneously extend optical and coaxial audio?
Yes. One of its key features is the ability to simultaneously extend both the optical and coaxial audio signals over the same CAT cable, replicating both outputs at the receiver end.
10.- What is the 3.5mm analogue output on the receiver used for?
The 3.5mm analogue L/R output is used to connect the equipment to amplifiers or audio systems that only accept analogue inputs, converting the incoming digital signal (selectable on the RX) to two-channel stereo (2ch PCM audio only).
