[Unlock a New Way to Enjoy Your Home Theater: Make Your TV Sound More Immersive]
To save space, most modern ultra-slim TVs have eliminated traditional 3.5mm or RCA audio output ports, retaining only S/PDIF coaxial or optical outputs. This coaxial-to-3.5mm/dual-RCA audio adapter cable is designed specifically to solve this problem for you.
In just three simple steps, you can connect your TV to an older amplifier, powered speakers, or high-end headphones, significantly enhancing your movie-watching and gaming experiences.
Key Benefits:
1. Independent USB Power Supply, Eliminates Background Noise
Unlike ordinary passive adapters, our product features an independent USB power supply (simply plug it into your TV’s USB port or a standard charger) to provide ample power to the internal DAC (digital-to-analog converter) chip. This ensures precise and stable conversion of digital signals into analog signals, resulting in purer, noise-free sound.
2. Dual Output Ports to Meet Various Needs
One end of the cable features both a 3.5mm headphone jack and red/white 2RCA connectors. You can plug in headphones to enjoy late-night binge-watching, or connect to an amplifier or speaker system to build a powerful home theater setup. (Note: We recommend using only one of these options depending on your equipment.)
3. Premium Craftsmanship
Sandblasted aluminum alloy casing: Features a refined metallic finish, is durable and drop-resistant, and effectively shields against electromagnetic interference.
High-density nylon-braided cable: Passes rigorous bending tests; is wear-resistant and pet-bite-resistant, with a service life far exceeding that of ordinary PVC cables.
24K gold-plated connectors: Resistant to oxidation and corrosion, ensuring excellent contact and signal transmission efficiency even after repeated plugging and unplugging over the long term.
📦 List of Compatible Devices (Wide Compatibility)
Input Devices: Smart TVs, Xbox, PS4, Blu-ray/DVD players, set-top boxes. (Must have a coaxial or S-PDIF port)
Output Devices: Speakers, Amplifiers, Soundbars, Wired Headphones.
🔌 Connection Guide (How to Use)
Connecting to a TV: Plug the end with the long silver metal connector into the TV’s “Coaxial” or “S/PDIF” output port.
Power Connection: Plug the USB connector into the TV’s USB port (or a separate 5V/1A power adapter).
Connecting to Speakers/Headphones: Plug the 3.5mm or red-and-white 2RCA connectors into your amplifier or active speakers.
(Tip: In your TV’s [Settings] > [Sound], change the audio output mode to “S/PDIF” or “External Speakers,” and set the audio format to PCM.)
FAQ
Q: My TV only has a coaxial output. How can I connect it to regular speakers?
A: You’ll need an active conversion cable with a digital-to-analog converter (DAC). Our “Coaxial S/PDIF to 3.5mm/2RCA Conversion Cable” features a built-in conversion chip and is equipped with independent USB power to ensure stable audio quality. It directly converts the TV’s digital coaxial signal into an analog signal, allowing you to connect to traditional amplifiers, speakers, or headphones.
Q: Why does this cable require USB power?
A: Although the coaxial port transmits digital signals, your speakers and headphones can only receive analog signals. This cable has a built-in conversion chip that requires additional power to drive the chip and perform the digital-to-analog conversion. USB power effectively prevents issues such as background noise, low volume, or disconnections caused by insufficient power, ensuring Hi-Fi-level sound quality.
Q: Does this cable support Dolby Audio?
A: This product is a digital-to-analog converter. To ensure optimal audio output, be sure to change the audio output format to PCM (Pulse Code Modulation) in your TV settings and disable Dolby/DTS audio. The stereo two-channel output produced this way is the most stable.
Q: Coaxial ports and standard red-and-white RCA ports look the same—how can I tell them apart?
A: Although they look similar, they differ in color and function. The coaxial port on a TV is usually labeled “Coaxial,” “S/PDIF,” or “Digital Audio,” and the port is typically black or orange. The red and white RCA jacks are usually analog audio inputs (L/R). Be sure to plug the long silver plug (coaxial end) into the TV’s coaxial output port—don’t plug it in the wrong way!
