PROZOR DAC Converter 192Khz Digital to Analog Audio Support 5.1CH DTS

We bought a new Sony 55" TV that has no RCA audio outputs to go to our vintage Pioneer SX-780 stereo receiver from the late 70's. So, I needed to go from the TV digital audio output to analog RCA audio inputs on the stereo. After reading the reviews and product descriptions of a number of these devices I decided to go with this one. (While I didn't know if I needed it or not, the volume control helped to sway me to this one.) I received the device, and it looks just like the picture on Amazon, and included the optical cable and a USB power cable. I connected a small AC to USB power adapter I had from one of my old cell phones to the switched AC outlet on the back of my stereo and plugged the USB power cable into that, connected the optical cable from the TV to the input and a set of RCA cables I had from the output to my stereo, and it works great. The volume control on the device works, but with the volume control on the stereo I'm not sure I really need it at this point, so I set it in the middle. Sound quality seems just great to me, so I'm very satisfied with this purchase.

This is exactly what I needed to make my stereo sound base behave more sanely with 5.1+ channel audio streams from my Roku. Since neither my Roku, my television audio output, nor my speaker base can decode DTS or AC3 to stereo analog, I often struggled to get audio from DLNA-streamed movies to play on my non-home theater tv. I kludged downmixing solutions with Serviio and with Plex, but there are situations where software hacks aren't effective. Since installing this little decoder box though, all my movies and streams so far have played clear stereo audio through my speaker base, appropriately blending the center and subwoofer channels as needed, while still preserving the original 5.1 audio stream for my more sophisticated home theater. To get my HDHomeRun over-the-air broadcast TV audio to downmix to stereo in the HDHomeRun Roku channel, I had to tweak my Roku's audio settings to force Dolby Digital. The HDMI output setting had to be set to Dolby Digital, channels = 2, and audio out set to Auto (DD and DTS). That's the secret sauce. My gadget chain goes HDHomeRun --> wifi --> Roku --> HDMI --> Panasonic TV --> optical --> this DD / DTS decoder box --> RCA --> Pioneer speaker base. Before making this change, I'm pretty sure the audio signal stopped at the TV for DTS streams. I think DTS (the company) believes that every television everywhere ought to be attached to a licensed DTS-decoding AV receiver, and so their restrictive copy protection should be transparent to anyone playing their content honestly. Cue middle finger. Since HDCP complicates DTS audio over HDMI, it seems that forcing Dolby Digital is necessary for the audio stream to be passed onto my optical cable, then eventually my speakers. Anyway, I wish I'd found this little box years ago. I love it! And the best part is, I don't have to explain to my wife and daughter how to operate it. It's automatic.

Bought this as the cheapest option of among Dolby/DTS down mixers to see if could force apps on my TV to stream higher quality surround sound and have it down mixed at my end vs. 2-channel stereo being streamed directly from the apps for my 2 channel audiophile systems. This only accepts Dolby Digital (and not the more common Dolby Digital Plus) and so it is still fairly limited. I do seem to get surround sound being sent from streaming apps, and it does seems to downmix 5 channel into a 2 channel sound (as I don't seem to be missing any of the back channel sounds). Surround sound does not sound much different (if at all) from 2 channel stereo; may be a touch wider than 2 channel stereo, but the difference is so small that I could be imagining it. Don't expect a virtual surround sound experience like DTS:X Headphones. The big surprise about this unit was the DAC - it is pretty good for mid-fi audio gear and I can easily recommend this just for the DAC alone. I have several "hi-fi" DACs - Denafrips Ares II, SMSL M500, and SMSL Sanskrit 10th Ed MKII - and this certainly is good enough for casual listening and I only hear higher noise levels when I hooked it up in my higher resolving audio system. The more intriguing part is that it offers a decent level of detail and clarity without the razor blade like sharpness and digital glare of my Sabre/AKM chip based dacs and so is not fatiguing for longer listening sessions. Of course, you won't get the spatial sound qualities of something like the Denafrips Ares II, but this is a dac for enjoying music over critical listening. I can’t find the dac chip specs, but I suspect it is from cirrus logic or TI which usually is the case in this price range.

The quality on these appears to have come a long way. Worked fine out of the box. Great for getting music to your stereo receiver. I just unplug the power when using the sound bar.

Works well. I was able to connect the audio from my TV's digital output to this unit then connect to my old (but wonderful sounding) stereo. I have OTA local TV stations and a streaming device connected to my TV and everything sounds so much better coming through the stereo speakers. Since my stereo receiver does not have any HDMI inputs or outputs, this was a cost effective, simple, effective way to upgrade from TV speakers. I used an old USB phone charger to power the device. The volume dial is a nice touch.

Lo recibí ayer, inmediatamente lo instalé y sorprendido con la calidad del sonido con Spotify desde mi televisor.

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.

The PROZOR DAC converter is working very well with my Bose speaker and woofer system and Samsung TV.

Connected my 4K TV to my Bose 5.1 Lifestyle 20 and it sounds excellent .

Per ora direi ottimo. Piu' piccolo di quello che si immagina dalla foto e ottima cosa il volume, che permette di avere un volume bello alto in uscita, a differenza di altri dac che hanno un volume di uscita anemico. Vedremo poi se ci saranno problemi di durata.

Used to connect Panasonic HZ1000 OLED TV to an old Pioneer XV-dv131 5.1 audio system. This DAC clearly met the need and working fine. Audio quality is great, no need to buy a sound bar now.

Now I can play BluRays, recording or live TV off the cable PVR, or even VHS tapes, and not have to move the home theatre audio input cables. All sound funnels through the flat screen TV on its way to the home theatre amp and speakers. Haven't used the built-in volume control or the 3.5 mm adapter, not sure if that would drive a set of earbuds off the TV. Volume control is the weirdest I've eve seen, with separate "louder" and "softer" buttons on opposite ends of the box...but in my setup I don't need to use the converter to control volume anyway. It says it does Dolby but I haven't verified that yet. Only stereo, not 5.1 surround sound but my speakers aren't set up for surround sound anyway. Pleased at the trouble-free setup. I powered the converter/decoder from a spare USB jack on our cable box that isn't used for anything anyway. The speed of delivery was the main reason for buying here, though the "guaranteed delivery" was again off by one day.

Necesitaba un adaptador que tuviera señal digital RCA que es la única salida de audio que tiene mi reproductor Blue Ray y que soportara también sistema Dolby (no por ser un adaptador digital necesariamente lo incluye). Pude conectarlo a mi sistema de sonido y ahora disfruto la calidad de sonido de mis películas.
