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.

Other than the fact that this only supports stereo (supposedly not even compressed 5.1 which Toslink does support), this is a great product, audio sounds perfect and zero stutters or audio dropouts over extended periods of time using OBS

Works fine with "Cubilux USB C to TOSLINK" sender from 2nd PC

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 run several PCs simultaneously for different tasks. I have one set of speakers on my desk. My PCs all have SPDIF Optical outputs on the back of their motherboards so I decided on one PC to be the "MAIN" PC that utilized my desk speakers. I plugged this device into my "MAIN" PC and then used a basic optical spdif cable to connect this device and my 2nd PCs optical output. I then went into my "MAIN" PCs sound settings (the old version of sound settings can be found by hitting WIN+R and then typing "control mmsys.cpl") , went into the Audio Inputs tab and found the "Cubilux SPDIF ReceiverSolid" device, right-clicked > Properties > Listen > checked the "listen to this device" button and BOOM I now hear the 2nd PC from the desktop speakers hooked up to my "MAIN" PC. I did this with 2 additional PCs and it worked out just fine. Windows recognizes each device as its own unique thing and I could go into the same Properties menu I mentioned above and RENAME each of the devices so I know which one is which and where each sound is coming from. This is awesome because the audio is clean (digital signal) and realtime (no latency) and especially cool because with this kind of setup there are no devices I need to plug in and power. Its just a basic SPDIF cable and the Cublix device. I even got one Cublix INPUT and another Cublix OUTPUT usb/SPDIF and that is allowing me to do this with a 4th PC (my laptop). So much easier to manage and cleaner sounding than any other convoluted setup I came up with before finding these. I would give them 6 stars if I could. Just because all the other ways to do this are such a huge pain in the butt.

I purchased this device to capture audio from my TV into a PC and then output it into an audio system, expecting transparent digital-to-digital conversion. After testing it thoroughly using multiple sources (PC motherboard SPDIF – ASUS Z790-A, TV optical output, and ASUS Xonar U7 MKII), as well as multiple optical cables, I observed consistent issues indicating problems with clock synchronization and signal integrity - even when using matching formats (48 kHz, 16-bit) on both output and input. When outputting a simple sine wave (starting from ~1 kHz and above), the device produces random short bursts of crackling noise. These artifacts are intermittent — sometimes the signal is clean for one second, then the crackling returns. Tested configurations: - PC (ASUS Z790-A onboard SPDIF output) → Cubilux (USB input) on the same PC - PC (ASUS Xanar U7 MKII SPDIF output) → Cubilux (USB input) on the same PC - PC (ASUS Z790-A onboard SPDIF output) → Cubilux (USB input) on a second PC - PC (ASUS Z790-A onboard SPDIF output) → Cubilux (USB input) on iPad - LG C1 TV (optical output) → Cubilux (USB input) on PC - LG C1 TV (optical output) → Cubilux (USB input) on iPad Compared to this device, the analog connection is noticeably cleaner, so I will continue using analog instead. In its current state, this device is unusable for my needs. I would not recommend this device for anyone requiring clean bit-accurate SPDIF capture. ---------------------------------------------- Question to manufacturer / community: Has anyone found a way to mitigate this behavior? Is there any firmware update available? Does the device support proper asynchronous USB audio feedback mode? Is there any configuration (driver/OS-level) that can stabilize clock synchronization?

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.

It's does what's on the tin! I know some users have reported some issues, but I can only assume it's either user error/lack of understanding or that there are some defective ones out there. or possibly lack of understanding. That is, there doesn't seem to be any inherent design flaw. Like many others, I'm using it to avoid ground loop noise when getting audio from 1 PC to another. My setup: PC #1 runs VoiceMeeter + Cantabile with VST plugins, then it's output over Toslink & then captured by PC #2 via this adapter. And yeah, it works perfectly! No noticeable delay and audio sounds just like the source, to my ears. (Another review reported measurable discrepancies in a couple of specific frequencies when using test patterns. He may or may not just have a defective one, but I can confidently assert that this is just the behavior of these, it's entirely undetectable in actual real-life usage. I think I did have to configure the source playback device to use the right 48kHz bitrate in the Windows sound settings, which may or may not have to be done depending on the default config of your output adapter, but it is a trivial 30-second task. Otherwise it's 100% plug and play—Windows Audio drivers support it natively. I'm actually planning to buy a 2nd one (as well as the inverse version Cubilux sells) to get sound from PC #2 back to PC #1 for sidechain-based acoustic echo cancellation. The only thing is I've wished for is control over the output level. This thing is just the volume that it is (which is generally sufficient.) In my experience this is standard for S/PDIF sound devices, though.

CD、MD、DATをSSDAC(ハイサンプリングDAC)で再生をするのにSPDIF(オプチカル )出力をUSBに変換する必要が有り、アダプターをAmazon で購入しました。 期待を裏切る程の素晴らしい性能です。 CDを今まではSSDACに専用CPUを接続してCDRで再生して聴いていて、全く不満はありませんでした。 しかし、CDRの代わりにこのアダプターとCDプレーヤーのSPDIF(オプチカル)出力を接続して聴くと明らかに低域が伸びるようになり、明瞭で解像度の高い音に成ります。 このアダプター録画専用品と明記している事の価値がかなり有ると思います。 そこで、オプチカル切り替え器もAmazon で購入しました。 これで、MD、DATも再生出来ますが、MDは本体と比べて、これがMDかと思う位の素晴らしい再生音に成ります。

I have used this adaptor / converter to connect the fibre optic sound output of my (old) TV to a USB-A 3.0 input on a Raspberry Pi. The Pi (running Raspberry Pi OS Trixie 64 bit) detects the device immediately and I am then able to stream this to my Bluetooth headphones. My TV does not support Bluetooth). I would strongly recommend this excellent product for similar applications.

Testé avec Pulseaudio - parfait.

Hatte keine Probleme damit, DAT-Bänder von einem gebrauchten DAT-Recorder auf den PC zu überspielen. Verbindung erfolgte sofort. Je nach verwendeter Audiosoftware kann man die Einstellungen für den Adapter auswählen/ändern.

I've been having trouble being able to capture optical in, have tried 2 different sound cards and nothing. But this was just quite literally plug and play, and it just works, I have nice clear audio. It is only 2 channel audio which is kinda a down side but I only need to capture 2 channel audio, so it works perfect for me.
