The Cubilux USB C/A to Optical & Coaxial SPDIF Audio Adapter provides a simple and reliable way to connect modern USB C devices to home theatre and Hi-Fi systems. Featuring both TOSLINK optical and coaxial SPDIF outputs, the adapter supports PCM audio up to 192kHz/24bit and allows either output to be used independently or operated simultaneously for flexible system integration. Both digital outputs support 2.0 stereo and 5.1 surround pass-through when used with compatible content and AV receivers, allowing you to enjoy detailed stereo for music as well as immersive multi-channel sound for movies and gaming. This makes the adapter ideal for upgrading laptops, tablets and USB C mobile devices to systems requiring a digital audio input. The optical output offers excellent resistance to electromagnetic interference, while the coaxial port provides strong and stable long-distance signal transmission. Together, they ensure clean, reliable and low-distortion digital audio whether you are connecting to a DAC, AV receiver, soundbar or home cinema setup. Designed for convenience, the adapter works instantly without drivers on supported platforms and includes a clear LED indicator to confirm power status at a glance. The package also contains a 1.2m USB C to USB C cable and a USB A to USB C adapter, enabling easy use with both USB C and USB A laptops, desktops and mobile devices.
