DIGITUS Bidirectional Audio Converter, Coaxial/TOSLINK™, digital

Product number: DS-40137
EAN: 4016032459002

Audio Converter 2-way Digital Coaxial/TOSLINK

Converts digital TOSLINK™ audio signals to digital coaxial signals (Cinch) or vice versa

  • Converts digital audio signals bidirectionally: TOSLINK™ <=> Cinch
  • Converts coaxial to TOSLINK™ or TOSLINK™ to coaxial signals
  • Connect devices with Cinch and TOSLINK™ connectors to each other
  • Coaxial and TOSLINK™ outputs can be used simultaneously.
  • Integrated amplifier for longer cable runs
  • Supports S/PDIF audio (TOSLINK™/coaxial)
  • Supported audio formats: LPCM 2.0 / DTS / Dolby-AC3


The DIGITUS® audio converter converts your digital audio signal from a coaxial interface into an optical signal via the TOSLINK™ interface. In addition, the reverse conversion of a digital optical signal into a digital coaxial signal is possible (bidirectional converter). This conversion allows you to connect your modern playback devices such as TV, media player or DVD/Blu-Ray player with Cinch or TOSLINK™ connectors. Not only is 2-way conversion possible with this converter, you can even use one input signal for both corresponding outputs on the opposite side. This means you can use both TOSLINK™ and Coaxial sockets simultaneously to connect two output devices at the same time. The integrated signal amplifier allows you to transmit audio signals over longer cable lengths. You can conveniently select the input socket using a switch on the side of the enclosure.
