J-Tech Digital J-Tech Digital Optical & Coaxial Digital Audio Extender/Converter Over Single Cat5e/6 Cable (PoC) up to 990 feet (300 Meter) for Dolby Digital, DTS 5.1, DTS-HD and PCM [JTECH-AET1000]

Worked perfectly for my client’s setup. I ran CAT6 from the patio TV to the living room Sonos Amp. The transmitter was connected using the digital optical output from the patio TV, feeding into the receiver at the Sonos Amp through the HDMI/optical adapter. The system performed exactly as needed.

son fáciles de instalar, tengo tiempo usándolos, son confiables.

When TV operate as a monitor for signals sent from an AV switcher or amplifier, the audio came out of the amp too. But nowadays, TV's are far more than just monitors: they're the epicenter of the streaming services- the source for the imagery AND the audio. Now the information is going out of the TV instead of into it. So how to you get the audio back to that nice remote 7.1 amp and in-wall speakers you installed 6 years ago? There is something called ARC (Audio Return Channel). This is supposed to output the audio signal through an HDMI cable to an amp. I bought converters to change the ARC signal to cat 5 and back again. (I only have cat5 in the walls) This did NOT work for me. And from what I understand, ARC tends to not work very well. These J-tech boxes do something similar, but they do it with the TV's optical audio signal output. It converts the optical signal to Cat5, then back to optical audio, then into the amp. The only issue is that you will have to provide power to the transmitter unit, which can be tricky in the spaces behind a wall mounted TV. No latency, sounds great, and fewer remotes on the coffee table. Highly recommended.

My receiver is an older receiver that only has optical inputs. My tv is quite far away and has an optical out. Luckily, I had run network cable through the walls a long while back. I found this product and it allowed to go optical out from the tv into 1 end of this dive, then network cable. The other end, network cable into this device, optical out to the receiver. It works without any configuration, I don't see any delay in the audio. It just worked out of the box and saved me from buying another receiver. One point to note: the optical cable only transmits dolby digital if I'm not mistaken. If you want Dolby Atmos, you would have to use HDMI-ARC or eARC so this is not likely the right solution for that. Still most of the content I watch is dolby digital for now and so this is sufficient for a while.

I encountered a situation during an installation where the distance between the TV and the media closet rendered the existing HDMI cable incompatible with a 4K device. To facilitate audio transmission between the two locations promptly, I utilized an available Ethernet connection. Initially, I had modest expectations for the performance of this device based on prior reviews. However, in my experience, I encountered no issues with sound quality, volume, or surround sound. Everything functioned flawlessly, which was very satisfying.
