Same summary

The Delock HDMI-HDMI 4K /3.5mm/ TOSLINK/SPDIF Audio Extractor 62784 converter is intended for users who are looking for a stable solution for separate capture of audio signals from an HDMI source - for example for connecting external sound systems or AV equipment. Its operation is most sensible in environments where a standard HDMI connection is not sufficient for the needs of separate transmission of multi-channel audio. It is suitable for business conference rooms, home cinemas as well as more demanding gaming setups. It is necessary to ensure that the converter is compatible with the connected devices and that they support the intended audio formats and resolutions; otherwise, limited use or the need for additional adjustment may occur.

In practice, this is especially useful in smaller meeting rooms, home entertainment electronics or when connecting sound systems where the HDMI input itself does not allow for easy audio splitting. The solution is equally suitable for consumers who want to improve the audio experience when watching movies, or for gamers who need low noise and a separate audio output.

Users appreciate the quality and reliability of Delock products, as they enable broad compatibility and a long service life in various environments.

Answers to frequently asked questions

Is this converter compatible with TVs, projectors and AV amplifiers?

Most TVs, projectors and amplifiers that offer HDMI and TOSLINK/SPDIF or 3.5mm connections are compatible with this converter, as long as they support the appropriate signal standard. It is recommended to check the specifications of both devices before use.

Can I extract audio from an HDMI signal even if the video image is standard definition (e.g. Full HD)?

Yes, the converter allows audio signal separation even at lower resolutions such as Full HD, but the key is the devices' support for the HDMI standard used by the converter.

What to do if there is no sound on an external device when connected?

If there is no sound, it is recommended to first check the audio output settings on the source (e.g. computer or console) and make sure that the audio format, such as PCM or Dolby Digital, is supported and activated.

Does the converter affect the picture or sound quality?

The converter is designed to maintain the original image and sound quality, provided that all connected devices are compatible and appropriate cables are used. Minor losses may occur with longer cables or non-standard layouts.

What situations is this converter not suitable for?

The converter is not suitable for use with older devices that do not support HDMI connections or when an analog conversion process is required. It is also not adapted to advanced AV systems with non-standard audio protocols.
