Cubilux USB A SPDIF Input Adapter for PC [Stereo Recording ONLY, NOT for Playing Audio] USB Optical Line-in Dongle, Toslink to USB Receiver, USB A SDPIF RX Interface Suitable for Laptop Computer

I got this device so I could connect the analog output of my turntable to to my laptop computer for vinyl record conversions. My turntable already had an analog to digital converter (ADC) that I'd previously bought from Amazon, which converts standard two-channel analog audio outputs on the turntable to a digital optical signal (SPDIF). My laptop, like most computers, has no connection for an SPDIF cable, so I needed a bridge between the ADC's optical output to my laptop's USB port. This device does exactly that.Optical SPDIF cables use a thin glass fiber housed in a protective sleeve, similar to a wire's insulated cover, to send light pulses containing audio information between stereo components. These cables use Toslink connectors at both ends that snap into compatible Toslink ports you'll find on some CD/DVD players, AV receivers, TVs and other components.So how can you connect a non-electrical optical cable to a computer's USB port? With this Cubilux adapter, which saved the day. The Cubilux does an excellent job of converting SPDIF optical audio signals into electrical data via a standard USB A port on your computer. All you need is an optical output on your source device such as a CD player or TV/video device (or, in my case, a turntable with an A to D converter), an SPDIF cable of the appropriate length for your setup, and this Cubilux adapter that plugs into your computer's USB port. Of course you'll need software in the computer that knows how to accept the USB port's digital audio signal -- I've been using a program called VinylStudio for this -- and you're off and running.This setup provides a bridge between the home entertainment world and the computer world, since SPDIF was only intended to provide clean digital connections between consumer electronics equipment without any electrical interference (it uses a light beam). It was never intended to be used with computers, so I'm very appreciative that this converter exists, and that Amazon sells it for a very reasonable price. I really don't know where such a device could be found anywhere else.Performance-wise, the adapter works like a charm. The sound quality is excellent, and appears to be transparent, meaning that it doesn't seem to be affecting or coloring the source signal in any way. It's powered by the computer's USB port, so there's no wall wart or other power connection required to use it.I'm very impressed by the adapter's performance. It's been rock solid during nearly 100 vinyl album conversions so far, and it does exactly what I needed it to do. Most importantly, t's allowing me to rediscover music, some of which is long out of print, that I've not heard for decades, which can now be stored on my phone and computer and listened to wherever I am. Many thanks to the company that developed this excellent product.

Effortless optical IN for recording, listening/monitoring. Tried it on my older Mac Book, it was detected right away and was selectable as a source. I was surprised a little by just how small this little dongle is.I also tested with my Windows DAW workstation PC. It worked fine, can record quick and simply with Audacity even, it was a breeze. It just works.So why did I buy this?I had a Behringer UCA 202, but it only does digital OUT.I have a Korg older harddrive multitrack recorder, however it has no USB interface, only SCSI, analog and optical.I can now get my tracks I record onto my multitrack recorder onto my PC and do so without degrading anything.I am super happy with how well it works and how it sounds like a 1:1 copy of what is on my recorder.I hope this guy lasts now. I was not aware of this brand until now, but after this purchase I will definitely be keeping an eye on their offerings. Very satisfied so far and the price was fair.

Works great... exactly what I needed.

I needed to use one of these to record an optical SPDIF source. It does that great. However, this sound device will not send any data whatsoever if the source is not sending any data. This makes some software behave strangely- when recording into Adobe Audition, for example, sound will not be recorded while the SPDIF source is turned off, where I would expect silence instead. This might be a desirable feature for some.

I'm using this to connect a Sangean FM Radio tuner to my Raspberry Pi as an audio source in Volumio. It worked perfectly with no configuration headaches.I don't notice any special noise (we're dealing with OTA radio after all), so I cannot vouch for the SNR or any of that stuff if you are using this for a super very high quality, low noise audio source. But if you just need to a toslink to USB connection, this is plug and okay.

I was trying to get sound from my shelf system into my Mac, so I ordered several things like this in sequenceProblem was, shelf system has no audio out except headphones & speakers - and I’m trying to save old tapesThe result was none of them worked, so the message is MAKE SURE YOU KNOW WHAT YOU NEED -This item isn’t broken, I was just wrong to get it

I plugged it in but it didnt work so I had to enable a setting in windows 11go to Control Panel under Sound, then Sound. Select the audio interface that your microphone is connected to and click “properties”. In the Properties window, select the Listen tab, then check the “Listen to this device” box.

Note: This is an input-only device for adding SPDIF input to your computer, it will *not* output audio.Works exactly as intended and without drivers on the latest version of Windows 10. Build quality seems solid, the housing is metal and the cable is nicely braided. Crystal clear sound without any hiccups, just make sure your source signal is stereo.Surprised it was this hard to track something like this down, most provide SPDIF output instead, but glad it exists.
