XPTSFDU HDMI ARC Adapter 4K60Hz Audio Extractor
The XPTSFDU adapter is designed as an HDMI ARC audio converter that sends TV sound from an ARC-enabled HDMI port back out to analog ports. It specifically provides L/R RCA and 3.5mm headphone outputs simultaneously, which helps connect legacy amplifiers, stereo speakers, or portable powered speakers to modern TVs.
- Requires a TV HDMI port labeled ARC and TV settings (CEC/ARC) enabled.
- Supports sending audio only when the TV is configured to output PCM 2.0.
- Use a high-speed HDMI cable (HDMI 1.4 or higher recommended) for stable signal.
192KHz ARC Audio Extractor To Optical + 3.5mm (Tihokile)
This unit extracts audio from an HDMI ARC input and provides Toslink (optical) and 3.5mm AUX outputs. The adapter emphasizes lossless audio transmission and supports up to 192kHz sampling on compatible signals.
- Single HDMI input (ARC) with no HDMI output — intended for ARC-to-audio use only.
- Not compatible with Dolby AC3 5.1 sources; set TV audio to LPCM/PCM for proper operation.
- Volume control relies on TV CEC; device requires 5V/1A power adapter.
4K@60Hz HDMI 2.0b Audio Extractor (avedio links)
The avedio links HDMI audio extractor is a versatile option supporting 4K@60Hz video and multiple audio modes. It offers Optical Toslink SPDIF and 3.5mm stereo outputs while supporting ARC function.
- Three audio mode settings: TV, 2.0CH, and 5.1CH for flexible output formats.
- 3.5mm output supports 2-channel PCM; optical supports 5.1 formats including Dolby and DTS variants.
- Supports HDR10, HDCP2.2, and up to 18 Gbps bandwidth for UHD compatibility.
eSynic eARC/ARC To Optical Audio Extractor
eSynic’s extractor focuses on eARC/ARC input to optical output, supporting high sampling rates up to 24-bit/192kHz. It’s intended for connecting HDTV ARC/eARC outputs to soundbars or home theater optical inputs.
- Supports PCM 2.0, Dolby 5.1, and DTS 5.1 signals; has indicators for 5.1/2.0 status.
- Only supports HDTV ARC/eARC inputs; labeled as a professional eARC/ARC-specific solution.
- No CEC support according to manufacturer notes; designed primarily for clean optical extraction.
Aodafy HDMI ARC Audio Extractor With Multiple Outputs
The Aodafy adapter offers a broad set of outputs — optical, coaxial, 3.5mm, and RCA — and is marketed as compatible with ARC and eARC ports. It’s built for setups where multiple legacy connections are needed.
- Requires TV HDMI labeled ARC or eARC and appropriate TV settings (CEC, HDMI ARC audio output, PCM format).
- Supports simultaneous outputs but will not work with soundbars that accept only HDMI (no optical/coaxial inputs).
- Provides a simple 3-step setup guide from the manufacturer to enable ARC/eARC operation.
Buying Guide: Choosing The Right HDMI ARC Adapter For Your Soundbar
Selecting an HDMI ARC adapter for a soundbar requires matching physical connectors, supported audio formats, and TV features. Below are key considerations when comparing adapters.
Audio Output Types
Identify what inputs your soundbar or receiver accepts: Optical (TOSLINK) is common for soundbars and supports 5.1 in many cases. Coaxial is another digital option. Analog options like 3.5mm or RCA L/R work for stereo systems but usually only carry 2.0 PCM audio.
ARC vs eARC
ARC (Audio Return Channel) supports compressed multichannel audio and stereo PCM. eARC supports higher bandwidth formats (uncompressed Dolby Atmos, PCM up to higher bitrates). If your TV and soundbar support eARC and you need high-bitrate multichannel audio, choose an eARC-capable extractor.
Supported Audio Formats
Check whether the adapter passes Dolby Digital, DTS, Dolby TrueHD, or only PCM/LPCM. Many analog outputs require the TV to downmix to PCM 2.0, while optical can often carry 5.1 Dolby Digital. If you need full surround, pick a device listing 5.1 support for the optical output.
TV Settings And Compatibility
Ensure your TV has an HDMI port labeled ARC or eARC. You will likely need to enable CEC/ARC settings and set audio output format (PCM, LPCM, or Bitstream depending on device). Read TV documentation and adapter notes to avoid format mismatches.
Simultaneous Outputs And Use Cases
If you need to feed multiple devices (e.g., soundbar plus headphones), choose adapters that support simultaneous outputs. Some extractors provide concurrent optical and analog outputs; others may prioritize one output type based on selected audio modes.
Video Passthrough And Resolution
If you route video through the adapter, confirm video passthrough specs (4K@60Hz, HDR support, HDCP version). Some units are input-only (no HDMI output) and are strictly audio extractors; others act as splitters with full video compatibility.
Power And Control
Many extractors require external power (commonly 5V/1A). Volume control may be handled by TV CEC rather than the extractor. If local volume control is important, verify whether the device supports it or if the TV remote will be required.
Physical Installation And Cables
Use high-speed HDMI cables (HDMI 1.4 or HDMI 2.0+) for ARC/eARC stability. Keep cable runs reasonable and avoid adapters when possible. Confirm included cables and whether you must provide an external power adapter.
Performance And Signal Handling
Consider jitter, electromagnetic interference, and sampling rate support (e.g., 44.1/48/96/192 kHz). Devices advertising high sampling rates may improve fidelity on compatible sources and receivers, particularly for high-resolution audio or critical listening setups.
Compatibility Checklist
- Does your TV have an HDMI ARC or eARC port?
- Does your soundbar accept optical/coaxial or only HDMI? (HDMI-only soundbars may not work with optical-only extractors.)
- Do you need stereo (2.0) or multichannel (5.1/uncompressed) audio?
- Will you need 4K/HDR passthrough via the adapter?
- Is external power acceptable for your installation?
