ROOFULL Bi-Directional Digital Coaxial to/from Optical Toslink SPDIF Audio Converter/Adapter/Repeater

***Update again. Same recurring problem with the new unit. This works but not in the long term. I am going to try another brand. You get what you pay for. I'll spend more now and maybe have better luck.**Update to previously negative review. This company stands behind their product. Seller Customer service was very helpful and responsive. We got the unit working again. It is important to use the power supply that came with the unit and not another power supply, which turned out to be one of the problems I was having. The power supply of the original purchase was defective and this company sent a new unit even though out of the return window. I am very happy again with the quality of sound this unit produces. I highly recommend.Very easy to install and sound quality was excellent after I hooked smart tv up to stereo receiver. I have been using it for approximately 27 days, on a daily basis. Turned it on this AM and it worked just fine for about 1 hour and then sound level dropped so low I could barely hear anything. Turned up volume to max on receiver and the sound was very fuzzy and full of static. Basically not tolerable. Even though I had no problems for almost a month, and the setup had not been touched since the original install, I tried to tinker with the volume and audio controls on the TV. Nothing I did corrected the problem. Finally I turned everything off for 20 minutes and re-started. At that point the excellent sound quality I had before returned. Everything crystal clear and sharp again. This should not happen. I have started a return. I need something that works without constant tinkering for much longer than the time I got with this device. I don't recommend.

Purchased this so I could connect my vintage CD player to my Wiim Pro Plus. Happy to say that the coax in, toslink out work beautifully and my CDs sound so much better now that I'm able to use the DAC from my Wiim. Highly recommend!!! 🙌🥂

So, you've bought all the parts for a new computer ("gaming" tier, whatever that really means). Everything's plugged in and ready to go, and you run into a snag: your motherboard sends power to your speakers to test them every time you turn on the machine. They pop LOUDLY. So you've got a headache, and your speakers might be in trouble if this happens often. What do you do?You grab a device like this, in my case. Optical connections don't send electricity to the speakers, which should make your ears happier and your speakers last a little longer.This was a replacement for an older device, which is no longer available. This one looks really nice - the build quality is good, and the power light is tucked in back. Inputs are simple: Coax or Optical. Outputs are a headphone jack, or coax (I'm guessing unbalanced, though I have not tried - this isn't exactly an expensive DAC). The power adapter is a little big, but not especially hard to work around. The Optical cable that comes with it is quite thin, but long; I didn't end up using it.To use this, just plug your computer (or similar device) into the inputs, and plug some speakers or headphones into outputs. The box handles the rest. The device is only used for converting signals; don't expect it to make your device sound different.So, the build quality is good, and it's easy to use. Any issues? Yep. If the DAC and speakers are powered, but there's no input, the DAC will send along some white noise. It isn't especially annoying, but my cheaper DAC this replaced didn't have this trouble. Still, it's not a big deal to turn off the speakers. I'm docking a star for that.Still, this is a good product for a cheap price. If you need to convert your audio from digital to analog, and don't have a lot of cash, this should do the trick. Recommended.

I wanted this to convert the S/PDIF output of my Numark TTX1 turntable to optical TOSLINK so I could transmit digital signal to my SoundBlaster Z SE soundcard for recording without possibility of analog noise from the computer. After failing to get this to work with two other options on Amazon, I was beginning to despair that my devices were somehow incompatible with this type of conversion, even though the output worked fine when sent to digital inputs on my stereo receiver. Much to my pleasure, however, this device works flawlessly. Highly recommend to anyone requiring conversion between coax and optical digital format.Do not let the product image fool you - it shows 2 devices stacked and rotated 180 degrees to show the interfaces on both sides. I initially bypassed this option despite it being the least expensive because that image had me thinking it was a larger, more ungainly device than the competition.

nice little unit. there's a switch that select what type of audio input it's receiving (coax {aka rca composite yellow connector} or toslink. i assume that it outputs to both coax and toslink ports (i'm converting coax to toslink and it worked perfectly). it needs AC power because of the optical connections.

I got this to serve TV sound out on an old TV which had no HDMI ARC and no optical audio. Now, the TV sound goes to my Roku Streambar for any input which is not the Roku. I haven't noticed any audio delay due to conversion, either. Setup was essentially plug and play.I will update if this device fails anytime soon.
