PROZOR 192kHz Digital to Analog Audio Converter - Converts Dolby AC-3 DTS 5.1CH Digital Audio to Stereo Analog Output, Optical to L/R DAC Decoder, DAC Converter SPDIF TOSLINK to Stereo L/R & 3.5mm

Awesome - works a treat! I'm not an audiophile, but have been an avid listener to an eclectic mix of music for 40+ years and have owned moderately high-end gear for many years: Cary tube amps, Cary tube preamp, Klipsch Cornwall speakers, NHT tower speakers, Arcam integrated amp, Audio Control Pantages amp, Golden Tube amp, B&O turntable, etc. Recently, I downsized my audio equipment and now mainly just listen to music from my desktop PC played through near-field Kef Q300 bookshelfs powered by the Pantages amp. I needed an external DAC that could accept a Toslink input and found the Prozor on Amazon and gave it a shot. I have been totally amazed at how well this unit works and especially sounds! Had originally planned this would just be a bridge device until I could research a higher end unit, but its performance has me rethinking my strategy - certainly in no hurry to replace it with anything 20 times more expensive. I know from past experience, I won't come close to receiving 20 times better sound. Besides the amazing detail produced in the data stream, the best thing about the Prozor is its invisibility - no sound is created by the device when nothing is being fed it. And, the volume control and headphone jack are gravy on this well-engineered metal cased unit. I have only had this unit for a few weeks and initially, I was going to send it back. It doesn't come with a power supply and I plugged the supplied USB cable into a USB 2 port on my PC and immediately got this very annoying low-level hum when no music was being played. The hum disappeared when the USB cable was unplugged, which pretty much confirmed it was coming from the Prozor. Fortunately, I eventually plugged it into a newly installed USB 3 port and was happily greeted by total silence. Its been silent ever since as long as it's plugged into a USB 3 port and not a USB 2 port. Strange, but absolutely true. Most audio reviews always include a qualifier stating how well the device being reviewed performs given its price level. No such qualifier needed for the Prozor - great sound - period!

Smartly packaged product is formed sheet steel with good slightly textured finish and clear easy white font markings. The PROZOR Digital to Analog Converter takes optical or coaxial digital audio of various formats and outputs analog audio for interfacing with external equipment. For me I wanted a headphone output from a TV that only had optical. This adapter easily setup, powered and delivered a fully adjustable level, clear and of good quality. Plenty of power to drive full size heavy, over the ear headphones. These are AKG K340 electrostatic-dynamic monsters from the 1980s. I did have to supply my own headphone adapter cable that took the 1/8 inch (3.5mm) phone (RTS) female socket and upsized it to a standard 1/4 inch to interface with my antique cans. The Device powers with 5v DC via USB micro connection on the device. Included is a micro USB to USB A (standard full sized USB 1.0/2.0 connector) approx 14 inches long. My late model 16x9 LED TV is typical of 2018 products, missing many of the input/output connections of earlier systems. Audio output is always lacking on these displays, even though there is an internal tuner that provides HD video. Most people do NOT want to use the substandard, micro "full-range" speakers included in bargain LED TV's. It's better to run analog audio to an external amplifier and heavier speakers. This D>A converter provides that connection wonderfully. Small and compact, powers to what is almost always nearby on modern video monitors, connects to optical or coaxial services. Included is also a short satisfactory optical audio cable. Sidenote, the tips of new optical audio cables have a silicone protector over the metal sleeve. This keeps scratches from the fragile fiber optic tip. Remove the silicone protector prior to cable insertion or you'll push the PC board mounted connector off it's mount. The PROZOR D>A has a red LED indicator on the rear when it's receiving 5v from USB. There is no way to turn it off from the device. That would have been a nice feature with the volume potentiometer knob. Coax input is the standard single RCA connector. There is no included coaxial cable. In addition to the 3.5mm headphone output, it also provides simultaneous consumer line level audio at the two rear RCAs. The front face volume pot does not attenuate the output of the rear line level RCAs. I've run this device for hours with no overheating or failure. It's compact and a good addition to a trouble shooting audio bag. Highly recommended.

It worked well, my grandson hooked it up to tv and receiver and works great.

Unit functions as described. Accessories are functional. Optical cable is fair quality, I upgraded to a higher quality cable for better performance.

Nicely made, cute form factor, and it works. I like to use my Audio Technica headphones while watching music videos and movies on my 4K TV. Unfortunately, most newer televisions have optical audio output and RCA audio output but no longer include a 3.5 mm jack. Enter this handy device. With the Prozor DAC, you can connect your optical audio output from the TV to this unit, using included male-to-male line that plugs into the DAC. You can then plug your 3.5 mm mini plug directly into the DAC and control the volume from the knob. It sounds great. You can also plug in a 3.5 mm that screws into a full-size audio headphone jack, as is often included with higher level headphones. This unit has sufficient power to fully support full audio plugs, heavier cords, and the more powerful headphones or speakers. Just a great solution! The sound, while it has been converted from digital to analog, is still excellent; certainly for general purpose listening. Also, you can additionally use this device to convert from digital/optical to RCA output, if your TV does not already have RCA audio outputs jacks. That comes in handy for connecting your TV to a heavy duty external speaker not made for a TV. The unit is small, made of aluminum, and had good build quality. One note is that it does not include a power adapter. However, I used the included USB C to USB cable to get power directly from the USB jack on the back of my TV. Highly recommend this device!

I purchased this converter to be able to use 3.5mm headphones with my PS4 with more sound fidelity than plugging into the PS4 controller. Setup was a breeze. SPDIF from the PS4 into the DAC box and then 3.5mm cord to the headphones from the box. All the cords being included was a big bonus. This setup allows sound to go to both the TV and the headphones. Paired with a nice pair of headphones, I was blown away with the improvement of sound and am quiet happy with the purchase. Two issues to be aware of with this PS4 setup. 1. The volume output is LOUD. I had to turn the volume knob on the DAC almost to zero and turn down all the game volumes. This worked to control the volume BUT at lower knob volume settings I noticed weird sound artifacts. In the right ear I could hear repeated, beating "thumps" during quiet moments. 2. As many reviewers have noticed, the left and right channels are switched. As others have mentioned you can just turn around your headphones but this seems like an issue that should be addressed. **I'll update my review if the seller or PROZOR reach out to address this issues. Perhaps I have a defective unit?**

I've got a convoluted home theater sound setup with ancient equipment that involves Optical SPDIF. I use optical so I can get uncompressed soundtracks, ( and also for technical reasons, it keeps the rest of the system from detecting that my TV only has 2 speakers, thus only sending a converted 2-channel stereo stream regardless of the source ). My father-in-law has a PHONAK hearing aid audio box that I piggie-back onto my audio split so it can send the audio directly to his hearing aids. This works - as long as the Phonak can understand the signal. A good bit of the time, I'm playing uncompressed DTS, Dolby Digital and all the usual suspects - not usually an .mp3 or .ogg vobis stereo audio stream. So I needed something that would take just about any audio signal and convert it into ordinary stereo that the Phonak can process - and this works like a charm. Had a similar problem with my father-in-law's TV and got another one to fix that problem - works perfectly. His issue was that his Roku audio was fine, but his Bluray player would send whatever audio is on the disc - and that's a crap shoot. He'd get audio on the disc intro or maybe the movie menu - and the nothing on the feature because it was 5.1 Dolby Digital or whatever via HDMI. I split the audio signal again and ran it throught he Prozor to his Phonak - and it works great. DEFINITELY going to keep the Prozor in mind whenever I need to convert audio signals to other formats to stereo via hardware.
