Works out of the box with MS-Windows-7,8, and 10 and Apple Mac OS-X Yosemite and El Capitan.
Toslink connection works with MS-Windows and Mac OS-X.
Plug and Play, No drivers or kexts to install.
Able to connect the toslink connection to my 7.2 surround sound AV receiver for true 7.2 Surround sound. My AV receiver was able to process the toslink digital signal in ( DTS, THX, Dolby Digital, 7 channel surround sound, Pro Logic, etc. ). They all worked.
I have tried several of these USB sound devices and have found this Behringer to be one of the best.
It just works with any Operating system. No need to install Drivers or Kexts.

Behringer makes three similar products with very similar names. This one - the UCA202 - provides line level RCA stereo inputs and line level RCA stereo outputs, a S/PDIF optical output, and a 1/8th inch stereo headphone output with a dedicated level control. There is also a small switch which turns the output monitor on and off (so the audio output doesn't interfere with your headphone listening).

The UFO202 includes a turntable pre-amp and a ground. The 222 is identical to the UCA202, but it has a snazzy red cover. To add to the confusion there is an identical UCA202 on Amazon for $10 more. God knows why.

I bought this to replace the similar Alesis in/out unit. The Alesis sounded dim, and the input volume control crapped out after four days - one channel was 6dB lower than the other. I sent it back.

Based on using the UCA202 constantly for a week, here is my assessment:

THE BODY - it is well designed, well thought-out, and well made. It's plastic, but is solidly made. (I wish it had that snazzy red body, though.) I like how the headphone volume control is recessed. I like how the connectors are all gold-plated (unlike the Alesis). I like the strong strain relief on the USB cord (unlike the Alesis). I like the reassuring LED that tells me it is connected to my computer. I like the way the labels are carved into the faceplate - no paint to rub off. I like having an optical digital output. I like the way it is small enough to take along with a laptop. (Gosh. I wish I had a laptop!)

THE SOUND - In short, it is fine. My cassettes go right from my premium Nakamichi deck into the computer, I edit the sound and bake a CD from the edit. And I get to bypass the cruddy soundcard in my old Dell (which has the sound quality and signal-to-noise of a six-transistor radio). The limiting factor is the cassette itself - not the analog-to-digital converter in the 202.

BTW - I compared two identical classical music recordings made with the Alesis and the UCA202. It was not even close - the Behringer was MUCH clearer and cleaner. I actually erased all the Alesis recordings and redid them through the Behringer, despite all the extra hours it cost me. The difference was THAT big.

I am not able to run the 202 directly through my big stereo rig, but it sounds pretty damn good on my $80 Grado headphones. It may not be the ultimate in audio refinement, but it is far more than adequate. For $30 I am a very happy audiophile. UPDATE - It is now plugged into a T-amp and good speakers and it sounds GREAT! UPDATE #2 - The 202 doesn't always sound good with cheap low-impedance headphone. See the end of this review.

I have looked long and hard at this product category - the next better unit up the food chain is the Cakewalk UA-1G USB Audio Interface for $90. The rest of the products at that price range ($100-200) include mic inputs, guitar inputs, multiple line inputs, mixers and other things I do not need. And the converters are about the same quality as the Cakewalk's.

Several devices will output your computer sound into RCA jacks, but this is one of the only ones that INPUT sound into your computer via RCA jacks. If you want to input (and edit and burn) cassettes, this is your baby! If you want to input LPs you either need a separate phono pre-amp or you go with the Behringer UFO202, which has one built-in. (I have not used it, so I can't comment on it, but Behringer seems to know what they are doing).

I'd give the USC 202 5 stars, but ....

THE INSTRUCTIONS - They stink. They go off on tangents about other Behringer products you don't need. They do not mention that the speaker in the diagram is a powered speaker. They do not explain that otherwise you need an amplifier to power your speakers.

They absolutely do NOT explain how you have to change some parameters in your Windows XP Control Panel. Or what those parameters are. They do not explain that you have to set up your computer's audio recording program (such as Audacity) to input and output through the USB connection. Figuring out all that jazz took me HOURS of research (though it takes only a few minutes to do).

That's one star down for pissing me off and delaying me two entire days. Unless you are willing to make a toll call, you reach Behringer tech support via email from their website. It takes a day or two to get an answer, but they are friendly and helpful and honest.

THE SOFTWARE - If you read the description, Behringer offers you "tons" of free computer software for your audio files. But don't think you will get some CD-ROM discs. It turns out that you have to download all three from different websites - and you have always been able to download them for free without buying any Behringer products. That's not dishonest or immoral, but it IS skeezy.

I'm a very happy camper with this product. If anything changes after a few months, I'll let you all know.

**********

UPDATE - One year in and everything is still just fine. Now that I figured out how to set it up (with help from a Behringer tech guy), I'd give it 5 stars for sound. But I won't because I had to email them to make it work.

BTW - Please see my answer to the first comment for details about setup.

UPDATE #2 - Everything is still working fine, but I found out some new information.

1) The $90-200 devices that input audio into your computer don't actually sound any better than this device. But they come with inputs for mics, guitars, keyboards, guitars and the like. So if that's what you want to do, buy one of them. But if you already own a mixer that does not have a USB connector, just plug that mixer into this device and get on with your recording.

2) A professional audio engineer, NwAvGuy, has measured the 202 to be extremely flat and the noise level to be below audibility. He thought the build quality was good and the electronic circuit implementation was superb. He even liked the cheap headphone volume control. His bottom line: "the Behringer UCA202 line outputs measure very well even for a more expensive DAC."

But he notes that the headphone output only works well with high impedance headphones (like a pro would use). Cheap consumer phones that run at 16 or 32 ohms don't sound so good. I have pro phones, so I never noticed it. He'll tell you all about it.

NwAvGuy UPDATE - Apparently, Amazon will not let me link to the review. So put "NwAvGuy Behringer" into Google and click on "NwAvGuy: Behringer UCA202 Review", and "NwAvGuy: UCA202 DAC Take 2" for his follow-up.

I needed a way to transfer some of my old and favorite vinyl record albums to iTunes, and this is the simplest interface between my AV Receiver and my Home Theater PC.

I plugged the Record Output from my Yamaha AVR to the Line Input on the UCA202, plugged the attached USB cable on the UCA202 into a USB port on the HTPC, and downloaded the latest version of (free) Audacity software to the PC. Audacity recognized the UCA202 as a generic USB audio input, so I just opened up a new project, switched the AVR to the Phono Input, cleaned the record well, started my turntable, and clicked the Record button in Audacity. When the first side ended, I quickly turned the record over and played the B side. Then clicked the Stop button in Audacity when the second side finished.

That was the easy part!!

It takes quite a bit of work to edit the audio file into something that I can import into iTunes!

Fortunately, there is a very good tutorial on the workflow process in Audacity's Help files.

The UCA202 does a great job of making the connection.

On the Cons side: the documentation provided with the UCA202 is awful! It barely covers the port and control descriptions, and provides no help for the software, so you'll need to look to Audacity for most of the support.

For the record, the "Monitor" switch on the UCA202 controls both the Headphone jack AND the Line Out RCA jacks, so it needs to be ON if you need to monitor the recording during the process. The volume control, however, only affects the Headphone jack.

In summary: the UCA202 is an excellent audio interface, but you'll need to be prepared to do some research, and spend some time in post processing to get good results. I would suggest if the songs are available on Amazon, iTunes, or online, it's WAY easier to download them than it is to record it yourself! However, I have some family heirloom albums that could not be obtained any other way.
