AVEDIO Links HDMI ARC Audio Extractor
This device acts as an HDMI ARC to analog converter with simultaneous outputs. It accepts ARC input and passes audio to optical, coaxial, and analog outputs, plus a 3.5mm headphone jack. It’s best for TV-based setups where the TV’s ARC port feeds a soundbar or an amplifier while providing flexible legroom for multiple speakers. The product supports PCM input and requires PCM/LPCM to be set on the source for proper playback. A key limitation is that it does not decode Dolby or DTS surround formats, which can affect multi-channel home theater experiences.
- ARC function improves integration with compatible TVs
- Coaxial and optical inputs provide flexible digital options
- Simultaneous analog, optical, coaxial, and 3.5mm outputs
J-Tech Digital Premium Audio Extractor
This model extracts digital audio from HDMI and outputs 2-channel stereo or 5.1-channel audio. ARC functionality is not supported, making it a simpler choice for setups that do not rely on ARC. It supports up to 4K@30Hz video and maintains high color depth via 12-bit/24-bit processing. It’s ideal for users who need to convert HDMI audio to legacy speakers or a home theater receiver without ARC features. A potential limitation is the lack of ARC support, so the TV must be connected directly to the input device rather than relying on ARC for audio return.
- HDMI audio extraction to analog stereo or 5.1
- 4K@30Hz video, HDCP pass-through
- No ARC support; best for non-ARC environments
AVedio Links 4K HDMI Audio Extractor
This HDMI audio splitter/extractor supports 4Kx2K at 60Hz and outputs through Optical SPDIF and 3.5mm, with ARC compatibility. It offers three audio mode options: TV, 2.0CH, and 5.1CH, enabling flexible setup for different home theater configurations. It’s best for users who want high-resolution video while routing audio to both a receiver and peripheral devices. A noted limitation is that it supports PCM for audio; Dolby/DTS formats may require other devices or modes.
- 4K@60Hz video support
- ARC-compatible output with multiple audio modes
- Primarily PCM/ LPCM audio handling
Tihokile HDMI ARC Audio Converter
This compact converter emphasizes multi-interface compatibility and smart matching. It connects HDMI ARC, SPDIF/Optical, Coaxial, and RCA/3.5mm outputs simultaneously, aiming to bridge modern HDMI sources with older hi-fi equipment. It automatically identifies input signal formats and optimizes output parameters for plug-and-play operation. It’s best for users who want one device to serve varied audio output needs. A caution is to ensure the TV’s ARC feature is enabled and that PCM/LPCM is selected for optimal audio, as Dolby/DTS formats may not be supported by all outputs.
- Multi-input and multi-output support
- Auto-format detection for ease of use
- Not all surround formats supported on all outputs
Buying Guide
What should I look for when buying an HDMI to SPDIF audio converter?
Check ARC compatibility with your TV, the type of digital inputs (optical/coaxial), and whether you need a simultaneous multi-output setup. Consider whether you require HDMI input with ARC or if you only need to extract audio from a direct HDMI feed. PCM/LPCM support is essential for reliable stereo playback, while some devices do not decode Dolby or DTS multi-channel formats.
Do I need ARC or is normal HDMI input enough?
ARC enables audio return from the TV to an external system. If your setup includes a soundbar or receiver that relies on ARC, choose a converter with ARC support. If you never plan to use ARC, a non-ARC extractor can be simpler and sometimes cheaper.
Which outputs should I prioritize?
Decide based on your audio system: if you have a receiver, optical or coaxial outputs are common; for headphone listening or powered speakers, a 3.5mm or RCA stereo output is useful. Some models offer all outputs simultaneously for maximum flexibility.
Will PCM be enough for my audio needs?
For most TV/PC listening, PCM or LPCM provides clean stereo sound. If you want true multi-channel surround, ensure the device supports 5.1 or higher and that your source material uses a compatible format.
What are common limitations to expect?
Many HDMI audio extractors do not decode Dolby Digital, DTS, or other encoded formats, which means you may lose surround sound effects with certain content. Also, some devices require specific input formats (PCM/LPCM) or have compatibility limits with certain TV brands.
How do I set up for best results?
Connect the HDMI source to the extractor’s HDMI input, connect the extractor’s outputs to your audio system, and ensure your TV’s audio settings are configured to PCM/LPCM (if required). If ARC is used, enable ARC on the TV and ensure the extractor supports ARC in its own settings.
