Cubilux USB A SPDIF Input Adapter, Compatible PC [Stereo Recording ONLY, NOT for Playing Audio] USB Optical Line-In Dongle, Toslink to USB Receiver

This device converts a digital optical signal from a DAC or other devices into a line-level signal that goes into your PC via USB. From there you can use Audacity or other apps to make a digital recording. My phono pre-amp, the Parks Audio Waxwing, has co-ax and digital outputs, so this is perfect for digitising vinyl records. The results sound beautiful. It handles up to 96 kHz/ 16 bit stereo. There's no discernable background noise or other colouring by the device, samples are clean. The Cubilux just worked as soon as I plugged it it, no setup was required for me on a Windows 11 PC. So overall, this little device is perfect!

See the photo. The HDMI audio extractor is fine but in a messy lab analog audio gets buzzes and hums. I had some success going via the DAC (box with white and red phonos) optical in and a short analog cable but with the SPDIF to USB the signal stays digital. I only need stereo. Incidentally the Prozar DAC costs 10 quid and comes with an optical cable, while Amazon Basics 0.5m cable alone costs a fiver. Linux info belowlsusbBus 002 Device 004: ID 0c76:1151 JMTek, LLC.

Useful way to get optical signal into the computer, however the information supplied was very brief. It needs a daw to allow the audio to be heard or recorded.

Works perfectly - clean audio, no ground loop noise or other nonsense. Autodetects bitrate (works at 44100 and 48000, not tested others), holds sync all day (10 hr recording). All good

It is working correctly when fed 48kHz stereo TOSlink S/PDIF signal. Linux Mint recognized it straight away. Audio is clear, bit-perfect, of course, and 100% stable. Incredible value for money here.

Really easy to use, just plug and play. Works exactly as expected.

Returned. To Amazon, great as usual

Was quite surprised given the relatively cheap cost. Now getting audio from my synths .
