PROZOR192Khz Digital to Analog Audio Converter Support 5.1CH Optical to RCA Converter with Magnetic Ring Power Cord Digital Toslink SPDIF to Analog L/R RCA 3.5mm Adapter for HDTV Blu-Ray DVD PS3 PS4

When we moved into our new apartment and I introduced the idea of "everything should work with everything" to my wife. She had one stipulation: get rid of the wires, even if that meant getting rid of my beautiful NAD 7225 stereo receiver from 1988. GASP! As it turns out, I had nothing to worry about.I discovered a tiny Bluetooth receiver to connect, using RCA cables, to my old amplifier. Now it was black in play. I found a tiny Bluetooth transmitter to connect to my Roku clicker via mini-plug to transmit to my stereo set. Computers and phones all have onboard Bluetooth capability, and therefore access to the amplifier. However, the challenge turned out to be the broadcasts I was receiving through my DTTV digital antenna connected to my plasma HDTV, which I also won't give up. The input into the TV is via a coaxial port. You see, back in 2005, congress allowed broadcast stations to drop the analog signals they had been sending for free through the airwaves since the 1940s. However, they would have to replace those with free digital versions, daily broadcasts of their one flagship channel, which they had to make available, for free, to anyone using a DTTV antenna. I use the "Antop Mini Big Boy" I got here. Using that rig, I saw every Olympic event I cared to on NBC, for free, in digital quality. The problem is that the only sound output from my old plasma HDTV is through an optical port. I needed to find a Bluetooth transmitter that has an optical input. Prozor seems to have cornered this market, on Amazon, anyway, and the PROZOR 192KHz DAC Digital to Analog Audio Converter with Bluetooth 5.0 Audio Transmitter seemed like just the right tool. I hooked its onboard optical input port to my plasma TV's optical output port and got...nothing. Turns out that when the input is from a "digital antenna," the sound output from the optical port is in "PCM" format (whatever that is). For whatever reason, the Prozor Bluetooth Transmitter can't handle PCM. To make the optical input to the transmitter work, you need to add this, the PROZOR 192Khz Digital to Analog Audio Converter. Now everything is working very well with a couple of drawbacks. Using this rig, I can only change the volume at the stereo amplifier and not any of the remotes. You'll have to get up off the couch now and then. A collateral benefit is that any sound coming through the TV will be sent to the stereo amplifier, whether from the digital antenna, the DVD or the Roku box. You can attach a Bluetooth transmitter to the Roku remote, directly, and in that configuration adjust the volume using the remote buttons and never have to get up, but we almost never use it. That's because the sound coming through the stereo is so much richer and truer than from the TV's on-board speakers, we don't have to make it loud to hear everything, perfectly, clearly, and at a reasonable volume. We use the closed captions much less frequently, too. The second draw back is that having to use this two device system, converting digital to analog, back to digital again and then transmitting it, I suspect there's an increase in lag time. This means that if I stare at the screen like a hawk, without blinking, I think the lip synch is not quite as good. My wife says she doesn't notice a thing, and, that's what really counts. What counts, for me, is that I get to see ballgames I can't get through Roku with HBO and Amazon, which is what we have. We get to see the old movies that are always on broadcast television, all kinds of playoff games, and every kind of award show. And all of this with beautiful sound and completely free.

I recently upgraded my main TV to a newer model that has digital audio output, but no analog output. I have an old Dolby ProLogic receiver that works well. I'd like to be able to connect my TV to the stereo for watching movies, but as I do this so rarely I really didn't want to shell out yet more money on a new receiver that won't get much use.This little converter solved my problems. It was able to connect to my TV using the included TOSLINK cable and connected to my receiver using a standard RCA audio patch cable. It's powered by an included USB cable. The manual said it requires a 1A USB port, although it did seem to work just as well in the 0.5A USB port on my TV, however I'll use the 1A so as not to damage it due to low current.Sound quality is good. I didn't notice any distortion and audio came through loud and clear. I don't have my rear speakers set up and I don't have a good test video, so I can't comment on if or how well it converts Dolby DTS to Dolby ProLogic. If I can find a good test video I'll have to try it out, but so far this has done everything I could ask for at an extremely reasonable price.-- UpdateI finally reconnected my rear speakers for my Dolby ProLogic system, and while I do hear sound from the rear speakers, it's nowhere close to what you get from a true Dolby Atmos or Dolby DTS system. However, for the cost of this little box I still feel this is an excellent value and a great device for connecting a digital system to an older analog receiver.

WOW ! , works fantastic ! , used the optical out on my Sony Bravia to my Sta 200D 1974 model stereo reciver. the sound is fantastic and so clear and clean it gets an all thumbs-up 👍.

works good.

Used this to connect my TV audio to my 1970s era Sansui receiver driving JBL floor speakers from the same era. Created perhaps the best "home theater" system ever, far superior to the newly-manufactured equipment.Optical is superior to getting a bluetooth adapter, which is also possible on most modern TVs. First, I've never been happy with the quality of audio streamed through bluetooth. While the technical specs suggest it should be fine, it's not. If you happy with what you get out of your bluetooth speakers, you will be happy. If you care about the accuracy and quality of music, you will be disappointed, especially if you can compare optical to bluetooth. I use the bluetooth if I must stream from my phone.Second, the line level optical is much greater than the equivalent bluetooth adapter. I don't know why, it just is. So if you like to crank it up, optical is the way to go.Two words of warning.First, be gentle with connecting the optical plug. This unit replaces the last one I had (different brand name, also from Amazon). While the enclosure is metal, pushing too hard cause the plastic plug casing to separate from the printed circuit board. Nothing I could do would fix it.Second, a general word of warning, not specific to this equipment. Most consumer electronic components used now days are not designed to powered on 24 hours a day. Most components are rated at approximately 7,000 hours of use. There are 61,000 hours in one year. Go figure.

The Prozar DAC was purchased to use with a Samsung 43" UHDTV that has an optical digital audio output. I bought the DAC assuming the signal would attenuate with volume to use into a Logitech THX computer speaker system. No fault of the Prozar DAC, the TV does not control volume output on digital audio (it's my own goof). I'm not returning it, maybe I'll have another use for it?

i was very satisfied with delivery ease of instalation and performance. use to convert optical audio output of new tv to analog input on my older sound system.

No, I'm not stupid- I tested with multiple optical cables, multiple RCA cables, multiple TVs, and multiple USB wallblocks. I even tried multiple models from this same brand.Prozor is just garbage. Idk how companies like this even stay in business.

Works perfectly. Using it to hook my newer LG TV up to an old reciever and couple of speakers I picked up cheap from FB marketplace. For the same cost as a bottom of the barrel soundbar I now have a pretty decent and very loud setup.

Cable too short

easily converts optical audio TV output to 3.5 Stereo so i can use my existing stereo system

If you're buying just to connect wired headphones to a Smart TV via the optical audio link, like I did, please note the volume cannot be reduced from the 100% default setting via the tv or DAC device (it does state this in the manual- no issue with the seller or product, just a note). The 100% volume default setting is quite loud. There is an alternative version of this product with a volume dial which I've just ordered to resolve the problem. I should have done more research first before purchasing, my fault so I'm not returning for a refund or anything, so I hope this helps someone not make the same mistake😊 Product works fantastic by the way, just the non-adjustable volume which will be an issue for headphones.

I have an equalizer and my TV only has Optical Audio capability. I could not connect my Equalizer with my bose speakers. This device made it possible. The quality is very good. I could feel the quality in my hands since it’s made of aluminum. It works very well. Excellent choice !
