Optical to Coaxial or Coax to Optical Digital Audio Converter Adapter, Bi-Directional Digital Coaxial to/from SPDIF Optical (Toslink) Audio Signal Converter/Repeater

Works exactly as promised. Simplified connecting our TV with S/PDIF (RCA-style) Coaxial Digital Audio Output, to a sound bar with Toslink-style Optical Digital Audio input. Set-up took very little time and effort. However, It would be helpful if the description mentioned that the device requires a free USB connection for the power. It does show the connector to plug into the back of the device is a micro USB connector, but it does not indicate the other end is a standard USB connector with no adapter for an AC outlet.

Works well for my needs

I needed this to connect one of my PCs to a Logitech Z550 with 3 digital inputs where optical and 2.5mm were already used. Plugged optical to this device and coax to Z550. Works fine with no issues.

As described with no issues as of yet

It works ok........but don't expect to find out the chip of the picture

Well built, solid housing. Easy to configure. I was so surprised by the solid construction that I went on their website to see if they had anything else that I could use.

Use it from my Kemper profiling head, or Helix Floor S/PIDF outs, which are both coax, to the input of my Apollo Twin interface, which is an optical port. I used to have a Focusrite interface, which had a coax in/out, and there doesn't seem to be any sound quality issues with this converter. Just make sure you have a really good digital coax like a Mogami, as the one sent with the converter seems like just a cheap coax cable. (A Digital Coaxial connection uses a cable that has RCA-type connectors. Digital coaxial cable is different from the standard RCA cable in that it is designed to handle the wider frequency bandwidth of the digital audio bit stream.) Optical signal is optical signal, so the one sent with the converter is fine, unless you wanted to get something that appears to be more durable.

My TV is old and only has a S/PDIF (RCA Coax) output. My new soundbar only has HDMI ARC/eARC and Toslink (optical) inputs. I used this adapter to connect my TV to my soundbar by converting the S/PDIF connection to a Toslink connection. It seems to work well. I am not noticing any sync or lag issues. Both PCM and Dolby 5.1 audio formats work. I can power the adapter using the "update only" USB port on the soundbar. It is nice that the adapter came with cables.

Works as intended. Came with the cords coaxial and optical. I didn't expect that and now I have extras.
