192KHz Digital to Analog Audio Converter Optical to RCA Adapter Upgrade Volume Adjustable DAC with Optical Cable, SPDIF TOSLINK to Stereo L/R & 3.5mm Jack Converters

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.

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!

Worked great as a modern CD DAC/preamp to 200W/channel Amplifier. Good piece of hardware to glue together old components to new.

Works great for me, where other similar products completely failed.

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!

Till skillnad från enklare varianter av denna typ av produkt som bara klarar av PCM klarar denna både DTS och AC-3. För mig betyder det att jag inte behöver ställa om den genomströmmade avkodningen till PCM t.ex.. i Kodi för att få rent ljud i hörlurarna. I annat fall med enklare produkter blir det bara digitalt oljud i lurarna. Produkten är robust bygg med metallchassi och med rätt känsla i den lilla potentiometern. Rekommenderas!

It's working well, just connected optical cable and changed on my TV LG OLED C3 settings audio out to optical. Working on all audio formats dolby, pcm or dts. For power I connected to one of TV usb connector. According to sound quality in general is good quality. But I download Tidal app to TV and compare audio quality on my stereo audio system from TV with this DAC and my Samsung Note 9 audio out also playing the same songs from Tidal. This phone has very good DAC. So audio from Samsung was more clear and detailed than Prozor. But in general for this price I think Prozor audio quality is good enough and I'm satisfied for this purchase.

I bought this for my tv, as the tv doesn't have a headphone jack. This DAC works as advertised, it connects to my tv via the digital audio out, and I can then use headphones to watch tv late at night. This DAC also has a volume control, which is handy as when I am plugged in, the tv volume control no longer works. The only downside of this DAC is that it seems to generate a bit of interference noise. I have to move it around to try and minimize the interference noise. Fortunately, you cannot really hear the interference noise once a movie or tv program is playing. Overall, would highly recommend this unit, it works well and was a good price.

​Ich stand vor dem klassischen Problem: Mein neuer LG Fernseher hat nur noch digitale Audioausgänge, aber meine geliebten Lautsprecher hängen an einem analogen Verstärker. Eine direkte Verbindung war also unmöglich. Nach kurzer Recherche bin ich auf diesen DAC von PROZOR gestoßen und er hat das Problem nicht nur gelöst, sondern meine Erwartungen übertroffen. ​Die Lösung für fehlende Anschlüsse Die Installation war kinderleicht: Optisches Kabel vom Fernseher in den Konverter, Cinch-Kabel vom Konverter in den Verstärker, USB-Kabel für den Strom anschließen – fertig. Alles funktionierte auf Anhieb und meine Anlage war wieder mit dem Fernseher verbunden. ​Unerwartete Soundverbesserung Was mich wirklich überrascht hat, ist die hörbare Verbesserung der Audioqualität. Der Klang ist jetzt spürbar klarer und natürlicher. Der Wandler scheint das Signal nicht nur umzuwandeln, sondern auch aufzuwerten. Details in Musik und Filmen kommen jetzt viel besser zur Geltung. ​Effektiver Störfilter Ein riesiger Pluspunkt: Ich hatte immer ein leichtes, aber nerviges Rauschen auf den Boxen, weil meine Lautsprecherkabel unglücklicherweise direkt neben Netzwerkkabeln verlaufen. Dieser DAC hat dieses Rauschen fast vollständig eliminiert! Allein dafür hat sich der Kauf schon gelohnt. ​Fazit: Wer eine einfache, günstige und qualitativ hochwertige Lösung sucht, um eine analoge Anlage an einen modernen Fernseher anzuschließen, macht hier alles richtig. Man löst nicht nur ein Kompatibilitätsproblem, sondern bekommt obendrauf eine klar bessere Klangqualität und eine effektive Reduzierung von Störgeräuschen. Klare Kaufempfehlung!

This looks and feels like a great quality product. Solid construction and works like a charm. Exactly what I needed to have my old receiver work with my LED TV.
