192KHz DAC Optical to 3.5mm Converter Kit, Optical Audio Cable to AUX Adapter 【Unidirectional: Optical to AUX Only】Specifically engineered to convert Optical (Toslink/SPDIF) signals from sources like HDTVs, TV boxes, or game consoles into 3.5mm analog audio signals. This conversion is unidirectional; it cannot convert a 3.5mm AUX signal from a phone into an optical signal for a soundbar. The unit is compact and lightweight, featuring a gold-plated interface for enhanced corrosion resistance and improved conductivity. 【High-Fidelity 192KHz Sampling Rate】Equipped with a high-performance DAC chip, it supports sampling rates of 32, 44.1, 48, 96, and 192KHz, and handles 24-bit S/PDIF incoming bit streams. This design minimizes electromagnetic noise for clear, lag-free audio transmission, making it ideal for movie watching or gaming on systems like PS4/PS5 without audio delay. 【Complete Audio Solution with Dual Cables】This kit includes two premium 5-foot 3.5mm cables, unlike standard converters that typically provide only one. You receive one male-to-female cable for connecting headphones and one male-to-male cable for direct connection to speakers, soundbars, or amplifiers. It is ready for immediate use in various setups. 【MUST READ: PCM/LPCM Setting Required】This device is a Digital-to-Analog Converter (DAC), not an audio decoder. It does not support 5.1 channel signals such as Dolby Digital or DTS. Prior to use, you must set your TV's audio output format to PCM or LPCM (typically via Settings > Sound > Digital Audio Output > PCM). Failure to do so may result in loud static noise or no audio output. 【USB Powered & Volume Control Note】The converter requires a power source to operate. Connect the included USB power cable to a 5V/1A USB port on your TV or a standard wall charger. Please note that your TV remote cannot control the volume of the audio output from this device. Adjust the volume directly on your connected headphones or speakers.
