What happens if my video keeps flickering, keeps dropping out regularly, or I experience audio delay sync issues?

Please ensure that you're using high-speed HDMI 2.0 cables which are no longer than 20 - 25ft. with our extractor. HDMI cables longer than that length may cause intermittent signal issues and connectivity issues.

Upon connecting, I am getting buzzing sounds from my audio system. What can I check for?

Make sure that the cable connections are properly seated in the device ports. For audio buzz, ensure that the audio output being sent to the extractor is no higher than standard Dolby Digital for Optical, and 2.0Ch for 3.5mm L/R audio out.

The unit worked well but it had a short lifespan which was unsatisfactory.

To ensure that the unit lasts a long time, plug it in to a surge protector and unplug the power from the unit if it's not being used for a longer time period. When connecting and disconnecting cables, please do so gently as it can damage the ports.

What can I do if I am not getting any sound from either the Optical or L/R 3.5mm output?

Check your input source devices' audio settings and ensure that the audio output is set to HDMI, and the audio format is either standard Dolby Digital (For Optical out), or standard 2.0Ch (For Optical out + 3.5mm out simultaneous audio).

Does this device support HDMI-ARC function where I can take audio from my display and send it to external sound system?

No, this unit does not support HDMI-ARC function. For that, please search for ASIN: B095DD4NW8; HDMI audio extractor with ARC function.

Fonctionne super bien. Belle qualité d'image, belles couleurs et les contrastes.J'ai utilisé cette appareil avec une source HDMI/TV avec le son et l'image, mais mon récepteur/ampli vieux de 12 ans env. est avec le son et l'image séparé. Cette appareil a bien pris la réception du son et l'image pour envoyé le tout séparément dans mon récepteur/ampli.J'ai été conseillé d'utilisé un convertisseur/extracteur car mon cinéma maison est avec un projecteur sur écran.Car avant d'utiliser cette appareil je n'avais que l'image mais pas de son. Maintenant tout fonctionne à merveille.J'ai attendu 2 mois avant démettre mon commentaire car avec l' achat d'un autre fournisseur après 2 semaines d'utilisation tout a arrêté de fonctionner.Mais avec l'appareil de J-TECH DIGITAL tout va pour le mieux. Je recommande...

Plugged it all in and it worked right away. I wanted to split audio from my AppleTV to my older AV amp that only has optical inputs. Works well.

I purchased this from Amazon UK and it arrived the next day. However I was very disappointed to find that the power adaptor was not fitted with the 3pin UK type wall plug. It had a US/Canadian fitting. This made it useless to me so I returned it. Such a shame as it seemed to suit my needs and I was looking forward to trying it.

Easy to set-up, flawless HDR 4k 60Hz HDMI output to TV and 3.5mm/RCA audio output at the same time to a karaoke machine. This device is very reliable. So much that i forgot that it's there doing it's magic after installing it a few weeks a go. The Wife is happy and so am'i. Thank you J-Tech for designing such a great device!
