Digital Audio Extender Converter for Optical/Coaxial Audio Over Single Cat5e/6 Cable (PoC) up to 990’ (300m) for Dolby Digital, DTS 5.1, DTS-HD, PCM [JTECH-AET1000]

Works well.

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

Works well for my setup. Used to connect Sonos Port in basement server to upstairs stereo. The transmitter runs cool, and receiver is plug/play with no additional electrical plug in. I took advantage of the duel plug running audio from Toshlink output to Schiit Modi DAC on main stereo and digital coaxial to another system via in wall coaxial connection. Allows me to have Sonos in multiple rooms with one Port. My Cat6 run is probably about 50 feet, and audio sounds great to my ear.

Works great for connecting the optical output from my TV to a remote media rack. Nothing to configure - just plug in optical cables, Ethernet cables, and the power supply. The power supply can only go on one side of the link, so make sure that is OK for your use case.

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.
