Amazon Basics 4K HDMI Audio Extractor with Toslink

Amazon Basics 4K HDMI to HDMI and audio extractor converts an HDMI signal into pass-through 4K video while splitting out stereo RCA or Toslink SPDIF audio for TV, set-top, or AV systems.

This compact metal-box converter lets you use HDMI sources that lack a separate audio output—like streaming sticks, Apple TV, Blu-ray players, game consoles, and some laptops—while sending full-resolution video to your display and simultaneous analog or optical audio to soundbars, AV receivers, or powered speakers. It supports up to 4K video at 30Hz and a range of 1080p/720p options and handles both compressed and uncompressed two-channel audio formats.

How does this extractor preserve video quality while sending audio separately?

The unit accepts a single HDMI input and passes video to an HDMI output while extracting two-channel audio to RCA (left/right) and Toslink SPDIF ports. Its design supports 8-bit 4K at 30Hz and higher-bit-depth 1080p at 60Hz, so your picture stays clear while audio is routed independently.

• 4K (8-bit) pass-through at 30Hz for UHD sources
• 1080p/720p support up to 60Hz and 3D formats
• Simultaneous HDMI video output and Toslink/RCA audio output
• Durable metal housing for stable signal handling

Which audio formats and outputs are supported for my speaker setup?

This extractor focuses on two-channel stereo output and optical digital audio, making it ideal for stereo systems and many soundbars. It supports both uncompressed and compressed two-channel audio, delivering a reliable analog RCA or Toslink SPDIF feed to downstream equipment.

• RCA left/right analog outputs for legacy amplifiers
• Toslink optical SPDIF for digital soundbars and receivers
• Works with compressed/uncompressed two-channel audio streams
• No multi-channel surround extraction—best for stereo or optical-compatible devices

Will this work with my streaming stick, console, or Blu-ray player?

Yes—devices that output HDMI video but lack a dedicated audio output are typical matches. Plug the source HDMI into the extractor, connect HDMI out to your display, and use RCA or Toslink to route audio to speakers, receivers, or soundbars for improved sound without changing video routing.

• Compatible with Apple TV, Fire TV, Fire Stick, Blu-ray players, and game consoles
• Also works with PCs, laptops, DVRs, and HD cameras that use HDMI
• No driver or software required—hardware-based conversion
• Requires compatible cables and a power source for the converter box

How easy is setup and what should I check before buying?

Setup is straightforward: connect the HDMI source to the extractor, attach HDMI output to your TV or monitor, and plug RCA or Toslink to your audio system. Verify your devices support the selected video resolution and that your audio equipment accepts two-channel RCA or optical SPDIF inputs.

• Simple plug-and-play connections—no apps needed
• Confirm TV/monitor resolution compatibility (4K@30Hz limit)
• Check receiver/soundbar input type (RCA vs Toslink)
• Include necessary cables and power adapter in your setup plan

Who is this for: The Amazon Basics 4K HDMI to HDMI and Audio Extractor is aimed at people who want better audio from HDMI-only devices—streaming sticks, media players, gaming consoles, and older AV systems—without sacrificing video quality. It’s a practical choice for homeowners upgrading to a dedicated speaker or soundbar, AV hobbyists integrating legacy gear, and anyone needing a compact, reliable HDMI audio split where full surround decoding is not required.
