Active circuitry maintains full signal integrity even on long cable runs. Converts Digital S / PDIF Coax to Digital Optical Toslink Audio. Input signal: Coaxial RCA audio signal Supports all S / PDIF digital audio transmission for incompressed PCM, LPCM, Dolby AC3, Dolby 5.1 and DTS sound. Compatibility and performance Function: Digital audio coaxial (S / PDIF) to optical Toslink conversion for , lossless sound transmission. Output: Digital Optical Toslink Audio to drive Toslinkequipped receivers, DACs, or sound systems. Formats supported: PCM, LPCM, Dolby AC3, Dolby 5.1 and DTS via S / PDIF transmission. Design intention: Active circuitry focused on maintaining signal fidelity across typical home theater cabling and setups. Use scenarios Home theater upgrade: Connect a Bluray player or DVD player that outputs through coaxial S / PDIF to an AV receiver or soundbar that accepts Toslink input, enabling multichannel audio without changing existing sources. Gaming or PC audio: Convert the coaxial S / PDIF output from a gaming console or computer to a Toslink input on a DAC or speaker system that supports optical audio, delivering immersive sound without reconfiguring hardware. Legacy equipment integration: Bridge older S / PDIF coaxial sources to modern optical audio devices, allowing seamless use of legacy components with newer Toslinkbased setups.
