PROZOR DAC Converter 192Khz Digital to Analog Audio Decoder with Volume Control Support 5.1CH DTS Dolly-AC3 Coaxial SPDIF Toslink Optical to RCA Adapter for HDTV Blu-ray DVD PS3 Home Cinema System

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.

This box converts Dolby AC-3 DTS 5.1, and PCM2.0 audio formats to two channel analog (L-R). The input can be either optical (SPDIF) or coaxial (phono plug). The output side has both a 3.5mm stereo jack, and a pair of phono (RCA) jacks. A short DC power cable is included that terminates with a USB-A plug, no power supply is included. Also in the box is a 6' optical cable. I bought this convert the Dolby surround formats my TV outputs into analog audio for two sets of BT headsets. They both would only accept PCM as the digital input, and converters I've tried created a lot of distortion. Setting the TV to output PCM took away the surround quality of my speaker system. This allowed me to leave the TV on it's best sound setting, and feed the headphone transmitters with analog L-R stereo, and the headphones are now distortion free.

I recently bought a Sony BluRay player that lacked RCA jacks, and only had a digital coaxial connection for sound output. I first (mistakenly) tried a different Prozor product that was only designed to decode 2-channel digital output, and it made a horrible buzzing noise when I tried to use it with the Sony player. This model I am now reviewing solved the problem though. Since I only have a 2-channel stereo with my TV, I have the DVD player hooked to this Prozor via its coaxial output, and then RCA cables from the Prozor to the amplifier. So far, sound has been perfect. Set-up was self-explanatory and simple. I wish a real power supply had been included rather than just a USB cable, but Amazon sold me one separately that works.

Worked as expected and showed up on time.

it is a good product, works great.

When it works, it works well. However, as others have stated I have to unplug and re-plug the power to get it to wake up. I've tried both RAW and PCM audio from my TV with no difference. I've had the audio cut off while using it, so it's not a case of it going into a deep sleep while everything else is turned off. The TV I'm using only has the coax audio out so I don't know if it would actually behave using the optical audio option.

If you are like me and were looking to use the amazing little system that is the Klipsch Promedia 2.1 THX Premium Desktop Speaker System with your TV or PS5 system, look no more. Grab this PROZOR 192Khz Digital to Analog Audio Converter that supports 5.1CH Optical to RCA (PST158a) now! I tried with the other, very well reviewed PROZOR DACO1s, which is kind of the same but without support for 5.1CH, but sound wasn't there. Thankfully I had already experienced how much of a beast this system is in my PC, so I knew what to look for. I knew a lot was missing. I ordered this converter and then tried the one with no support for 5.1CH (DAC01s) first. Sound was ok. Then, without touching the volume setup, I switched to the PST158a, hooked everything up the same, hit play and...O.M.G.!!!...ears blown!! This little monster came roaring back to life!! I almost cried...LOL! I had finally found THE converter that I needed!! I cannot talk to how much this converter will last, since I just literally tried like 30 minutes ago, but for the price, you cannot go wrong. Grab 2 and have one to spare! Again, this is the converter for you if you are trying to hookup your Klipsch PROMEDIA 2.1 system to your TV/PS5, etc.Just some insight: It only comes with the power cable without the plug, but you can connect it to a USB port on your TV if it has one. It will draw all the power it needs from there, which is minimal. I have an LG TV and I simply used the Optical Audio Out from my TV and connected it to the PST158a. Connected the power cable to an available USB port on the back of my TV. Finally, connected the 3.5mm connector from the Klipsch Promedia 2.1 to the PST158a and...Voila!...music heaven! Hope this helps! Enjoy!
