Bi-Directional Coax Digital Audio Adapter - Coax to Optical or Optical to Coaxial Converter

Works great. Came with converter, coaxial, audio optical, micro USB to USB(power). My TV only had "Coaxial Digital Audio Output". Plugged the supplied coaxial to TV and input on converter box. Plugged the supplied audio optical to soundbar and output on converter box. Plugged the supplied micro USB to converter box and USB to TV, that was enough to power the converter. I turned everything on and it was NOT working. There is a small switch on the converter, I flipped it, and all is well. Took 3 minutes or less. Sound quality was plenty good for me. I recommend.

I was helping my elderly neighbors by our vacation property. He had bought a new soundbar and it only had a HDMI ARC connection or digital optical connection. The older flat screen TV only had a digital audio out.The Digital Coaxial to Optical Converter was the perfect bridge between old and new technology. It came with the digital cable and the optical cable. A usb cable to connect to power on the TV. All I had to do is slide a switch to identify what the output version would be and connect the cables.It worked like it was supposed to and he has a working new soundbar. The quality of the Digital Coaxial to Optical Converter is very good. I don’t see any issues that could happen with the product.A good fix for a technology problem.

This product worked right out of the box, requiring only two minutes to connect and no app required. And it sounds absolutely fantastic. Playing an SACD disc from a blu-ray player into a WIIM pro-plus streamer/DAC, I could detect no audible signal degradation whatsoever. The SACD signal is converted from coax digital to optical toslink digital through this device, then passed to the DAC of the WIIM where it is decoded. It sounds fantastic. So why was this device needed? My Blu-ray player has a coax digital out, but no toslink digital optical out. The WIIM has a toslink optical digital optical input, but no coax digital input. This little box solved my digital interface issue! Highly recommended.

Blu-ray player only offered a single digital coaxial output which would not work with my system--this unit easily converted the coaxial to an optical cable input on the amp. BUT be aware the coaxial and optical cables included with the converter are cheap junk.I wanted to test the unit before a full-on set-up/install. No issues with the converter box but the audio signal almost immediately began to break up and drop out. Quickly replaced the supplied cables and had no further issues. Seriously, be sure you have quality coaxial/optical cables on hand.

works good

The converter did not initially work well and was producing static loud enough to drown out the sound. We needed this to connect a soundbar to an older TV that only had digital coax audio (spdif). As other reviews have stated, I replaced the coax cable to troubleshoot and now it works well. Buy without cables if possible and use quality cables.

This was exactly what we needed! Parents have an old flatscreen TV, and we had bought them a soundbar to upgrade the sound. This cable helped bridge the gap between old and new, plugging the coaxial into the tv and the optical into the soundbar. The box does need to be plugged into power in our setup. It comes with a USB power cord but no brick - had to find an old phone charger brick, but once plugged in the audio came through crystal clear!

Easy to install. Very useful for connecting wired digital coaxial connections to the digital fiber that goes into soundbars. $20 is a good deal for making my new Roku Soundbar Pro work with my old HDTV. I figure buy a soundbar that will work with my antique HD set, and can be used at 4k when I upgrade the TV. I generally buy latest featured equipment, so I don't have to buy it again when I upgrade connected equipment. Backwards compatibility is a blessing, and saved me from having to spend a pile of money on a 4k set when they are likely going to be dropping in price for Christmas.
