3.5mm AUX to SPDIF One Way Converter - This analog to digital o converter changes analog (3.5mm AUX) o signals into digital (TOSLINK/SPDIF) signals. Plug and play, powered via USB for stable performance, no driver installation required, and o transmits synchronously after connection. The optical plug features a snap-on design that stays securely in place, ensuring smooth insertion and removal. Connect your TV to a soundbar or home theater system for an immersive stereo surround sound experience. Supports PCM, Dolby, DTS, and 5.1 o formats, delivering cinema-quality o at home. Features a high-performance optical core that uses light pulses to transmit o, reducing electromagnetic interference for clearer, richer stereo sound and eliminating background noise. Compatible with PC, laptop, gaming consoles, and projectors with a 3.5mm o output. Color: black. Material: PVC + ABS + alloy. Note: The optical output supports stereo channels only, not 5.1 or 7.1 channel o. The USB cable is for power only and requires a 5V USB power source during use. If buzzing occurs, it may be due to ground loop interference; try connecting the USB power to a separate USB charger. Product appearance and printed text may vary slightly between batches, but this does not affect functionality. Package includes: 1 x 3.5mm to Fiber o Conversion Cable, 1 x 3.5mm male to male o cable.
