PROZOR 192Khz Digital to Analog Audio Converter Support 5.1CH DTS Dolly-AC3 Digital Audio to Stereo Analog Output

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.

I have a Tivo EDGE and it does optical audio output with Dolby or just PCM. But the output setting applies both to the optical output and to HDMI, so if turn off Dolby you are turning it off both for the optical and HDMI audio. I want to use an optical to Bluetooth adapter to work with headphones. I could not find one that accepts Dolby encoded optical input, so I tried this adapter. It works great, good quality components, converts the optical Dolby stream to analog stereo audio, but unfortunately, when I hooked the analog audio into the Bluetooth adapter's stereo input (using an RCA to mini plug cable) I wind up with a lot of power hum in the output to the headphones. Unclear what is causing it, but it's there and it's not there when I turn off the Dolby in the Tivo EDGE so it can drive the Bluetooth adapter. So, I'll keep looking for a Dolby optical input to stereo Bluetooth adapter, and maybe I'll find one, but I did not find the combination of discrete components a good solution.

Works great with my samsung tv. Using it with a Rockville karaoke machine. That doubles just as a sound bar. Impressed how clean the audio is. Dont experience any whine at full volume that I seen a couple other reviews say. 4 stars only because it should come with the stand alone dc power plug. It doesn't. It comes with a usb connection cable that youd need the wall plug to use. Cables are a little short for my liking but not unusable. Would buy again.

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.

The product was easy to set up and is functioning exactly as specified in establishing a connection from the digital out port from my TV to a pair of powered bookshelf speakers. The Prozor DAC is great value.

I purchased a new TCL Q6 TV. I connected the TV to my 20 year old Onkyo TX-NR702 with an optical cable. Things were great in Zone 1 but no audio in Zone 2. This is understandable since Zone 2 is strictly analog. So searching for a remedy I came across the Prozore 5.1 DAC Converter. Reviews were good so I purchased one. It is simple to install. I used the USB port on the TV as a power source. I then connected the optical cable from the TV to the Prozore and then connected the RCA jacks to Zone 1 on the rear panel of the receiver. Turned everything on, selected Video 1 on Zone 2 and it worked! I couldn’t be more pleased. If you have a similar issue you can’t go wrong with the Prozor converter.

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.

This little wonder saved the day! Here's our story. We moved and bought a new state of the art LED TV. Our old TV had an analog audio output jack I used to feed audio into a legacy hi-fi system that has phenomenal sound. We just turn on the legacy system for exercise or movies. Alas, the new television had an optical output S/PDIF TOSLINK connector for the audio output, so we needed a clean solution that can decode all the different kinds of audio we might play on the new TV. Since it is a Smart TV, there are apps for YouTube, Disney+, Netflix, Hulu, etc. that output audio in a very wide variety of formats and bitrates. I'm pleased that this unit has faithfully and flawlessly decoded every single digital audio source that we've experimented with. It's nice that this just works. Installation was very easy. You simply connect the included TOSLINK cable from the output on the TV to the input on this product. You connect the analog output jacks (L+R) on this product to the input jacks of your legacy equipment (L+R). They provide a 5V power cable, you provide a USB power port. You connect the included cable to your spare iPhone charger (the small square ones work fine) and turn it on. Again, this was easy and the device worked flawlessly from the first moment we used it until today. If you're looking for a reliable, compatible S/PDIF TOSLINK decoder that can handle the latest audio formats and bitrates and convert to analog for legacy audio equipment or maybe a sound bar, then this product will work perfectly for you. I highly recommend it.

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.

Ottimo prodotto ... offre quanto dichiara e resuscita vecchi impianti audio 5.1 o 7.1 ... poca spesa tanta resa ... chiaramente bisogna accontentarsi

テレビの光デジタル音声出力を、アナログオーディオ経由で聞くために購入しました。最初にAmazonで最安値クラスのDACを購入したのですが、音が悪く音楽物などは聞く気になりませんでした。その後別の安価なDACを購入しましたが、その製品も満足できる音ではありませんでした。 音が悪い原因としてDAC自体の性能が悪い事と、テレビ側でPCMに変換して出力している事の2つが考えられたので、DACを買い替えるにあたりPCM以外のフォーマットにも対応しているこの製品を購入して実験してみました。 テレビ(REGZA Z570L)のデジタル音声出力は、PCM、Dolby Audio、デジタルスルーを選択できます。有名メーカーであれば他社の製品も似たような物だと思います。 まず最も劣化が少ないであろうデジタルスルーを選択すると ・テレビ放送(地デジ/BS/BS4K)及び、それをDRまたはAVC録画したMPEG2-AACとMPEG4-AACは音が出ません。 ・ブルーレイレコーダーでDolby Digital 5.1ch、Dolby Digital 2ch、DTS対応のメディアを音声を切り替えて試したところ、どの音声を選択しても音が出ました。 ・Prime Videoはタイトルによって音が出る物と出ない物があり、音声にDolby Digital Plus(7.1ch)が採用されているタイトルは音が出ません。 ・YouTubeは音声にAACやOpusが使用されているので音が出ないはずですが、いくつか動画を見た限り音が出ました。テレビ側で音声を変換しているのかもしれません。 ・自分で音声をDolby Digital(AC3)にしてエンコードした動画や、ビデオカメラで撮影したAVCHD形式の動画(音声はAC3)は音が出ました。 対応していない音声フォーマットで出力しても、無音になるだけでノイズが発生する事はありませんでした。 次にDolby Audioを選択すると上記の全てのソースで音が出ましたが、音声を変換するせいか映像に比べて音声が僅かに遅れます。加えて早送りや巻戻し後などに音が出るまでに僅かにタイムラグがあります。 最後にPCMを選択すると上記の全てのソースで音が出ましたが、サラウンド音声がテレビ側で2chにダウンミックスされて出力されるせいか、あっさりした音になります。タイムラグは感じません。 私のオーディオシステムは2chなので、PCMとデジタルスルーでそれ程違いは無いかと思っていましたが、ソースがDolby Digitalの場合はデジタルスルーの方が明らかに低音が豊かで、音の広がりも感じられます。テレビでダウンミックスするかこのDACでダウンミックスするかの違いなのですが、サラウンド音声を左右チャンネルに振り分けるバランスが違うのではないかと思います。テレビのサラウンド放送をPCMとDolby Audioで聴き比べるとそれ程の差は感じません。 結論としてはテレビのデジタル音声出力は通常はPCMにしておき、サラウンド放送はDolby Audioに、Dolby DigitalやDTSのソースを再生する場合はデジタルスルーに変更するのが良いようです。 DACとしての性能はなかなかで、これまで使用していた安価なDACよりも明らかに音が良く、高音が滑らかで刺々しくないので、音楽物にも充分使用できます。 本体のサイズはこれまで購入したDACの中で最も小型で、LED電源ランプの輝度も控えめなのでテレビの後ろに置いても邪魔になりません。音量ボリュームがあるので、レベルを他のソースと合わせる事ができて便利です。 付属品のコード類は取り立てて良い物ではありませんが、普通に使えるレベルです。USB電源ケーブルにノイズフィルターが付いているのは良いです。 テレビ用のDACとしてコストパフォーマンスは最高だと思います。
