Cubilux USB C to SPDIF Transmitter, Unidirectional Type C to Optical Audio Output Adapter with 192KHz/24bit DAC for MacBook Pro/Air, Laptop, Computer

Working properly with 5.1 system connected to Mac mini M4 pro.

good item

This is a very interesting product! If your soundbar needs HDMI ARC(which isn't available in laptops or PC)or S/PDIF to play actual 5.1, and any other method is simply upmixed stereo, then this is what you are looking for. It works straight outta the box. The build is quite durable metal, connects with great signal quality as it uses optical medium. If combined with APO driver in laptops or PC, you can make your computer speak dolby digital AC3(with a bit of configuration) to the soundbar as a global setting. Works like a charm for my home theatre. Ignore this product if everything I said above is gibberish to you and if you think the sound bars play true 5.1 in any type of connection.

Works as advertised. But overpriced for what it does

I purchased this as a (hopefully) cheap way to upgrade my audio across the board with the intention to use the SPDIF with my Fiio E17 portable DAC/Amp which contains an Optical connection via an adapter which it came with. So I figured instead of using the 3.5mm connector to pipe my audio through why not get this and use USB audio and convert it to clean Optical - and it works perfectly plug and play with my phone/tablet and my Steam Deck and on PS5 you just have to use the front USB C port switch to the SPDIF converter (oddly enough not the DAC) and it works and sounds fantastic! No bluetooth either which means no audio lag or loss of quality. So this converting USB audio to clean Optical via a DAC/Amp combo using Quobuz bit perfect mode or Amazon Music Ultra HD tracks wow! Movies sound fantastic too. As do games. Delighted with this product. Its a lot smaller than it looks too Might try and get a small Optical cable to cut down on the wires making it more portable.

klappt perfekt damit vom iPhone Musik auf den Minidisc Rekorder zu spielen. Ich kann nichts beanstanden.

My prior desktop computer had an optical output. With my laptop, no such luck. So I purchased this unit and it worked perfectly right out of the box, no Windows settings required adjustment or configuration. I should add that I actually connected this unit to a docking station that is connected to my laptop and not the laptop itself, and was concerned that this may present a complication but it did not. The computer located the converter right away. The sound quality is excellent in my opinion. I source music to a pretty high end audio setup and there is no background noise or hiss, and no stuttering or other sound issues.

Excellent little device at a great price. It acts as a USB Audio Class 2 device. Plug it into USB on a computer, phone or tablet (including via a Lightning adaptor on iPad/iPhone), and you get out optical audio, suitable for many items of audio equipment. I tested it thoroughly. It provides bit perfect performance on CD-standard digital audio -- 44.1kHz -- and also supports 48kHz, 96kHz and 192kHz, 16 and 24 bits. It does NOT support 88.2kHz or 176.4kHz. These are relatively rare, but do exist. Your device will convert them to 96kHz or 192kHz. Formats as shown in image. In 99.9% of use cases, though, the gadget it great.

Werkt probleemloos, geen stroom nodig.
