USB A to Optical SPDIF Audio Adapter

Dimensions: Approx. 9.5 x 3.5 x 1.8 cm (L x W x H); Weight: Approx. 42 g; Input: USB Type-A (5V DC powered via host); Output: Toslink optical SPDIF (S/PDIF compliant, unidirectional); Material: PVC outer sheath with aluminium alloy shell; Interface: Gold-plated USB and optical connectors. This adapter converts digital audio from a USB source (e.g., laptop, PS4, desktop PC) into optical S/PDIF format for direct connection to AV receivers, soundbars, DACs or home theatre systems with optical input. It supports standard PCM stereo audio transmission — ideal for high-fidelity playback without latency or interference. No drivers or external power supply required: draws full operating power from the USB host port. Designed for seamless integration in entertainment setups: connect your TV, gaming console or computer to an optical-input audio system to enable immersive 3D surround sound for films and games. Also enables simple home KTV-style audio routing when linking TV to external speakers. The unidirectional design ensures stable, jitter-free signal transfer — it transmits only from USB to optical, not vice versa.
