    My house is wired for ceiling speakers. I want to use AirPlay 2 to control them all so I’ll have multi room audio. Can I buy a multi zone power amp and connect an Apple TV (3 or 4) to this extractor which connects to the power amp input so i can stream without TVs? And can I do 1 per each zone?

    I just want to connect this device from my standard hd tv to a soundbar with an optical audio input, the soundbar can do 7.1. Can this device turn the output from the tv to 7.1 to the soundbar?
    Rashad H on Jan 2, 2018
    BEST ANSWER: Similar to the question/answer above, you're limited to Dolby Digital 5.1 or DTS 5.1 if you connect by optical or coaxial. You'll need to connect to the soundbar by HDMI to get 7.1, which I'm assuming your soundbar has if it can do 7.1...
    Will this decode DD+ to DD?
    Bob S on Apr 13, 2018
    BEST ANSWER: Hi Bob, I can't answer reliably since I am only pulling the audio off to feed a personal listening system in our bedroom. Reading the specs makes me think the converter pulls off the audio stream and converts it to stereo, coax, or optical outputs. I don't know that it converts the "digital audio compression scheme" of the input.
    Which connector do I use to output multichannel SACDs?

    Does the adapter work on 220V?
    A shopper on Mar 4, 2018
    BEST ANSWER: Yes. Input: 100-240Volts, 50/60 Hz, 200 mA.
    Can multiple audio outputs be used at the same time? I want to connect the coax to one audio device and the 3.5mm to another.
    Eric F on Jun 12, 2018
    BEST ANSWER: Yes I currently have all three audio outputs hooked up to three different devices. I have 3 of these and am very satisfied with they way the work.
    I want to connect my xbox 360 as the input and my tv as the output. Will it work ok if I use the 3.5 for my earbuds so I can play at night without waking my wife up?
    A shopper on Aug 3, 2018
    BEST ANSWER: I don't see why it would not work with the 3.5 output.
    My PC has a 4k GFORCE video card, I need to feed the 4K signal to this and split the audio signal so that I may plug OPTICAL or COAX out to my receiver and get DTS 7.1 Sound.
    My receiver only takes HDMI 1.4a, that's why I need the 4K Signal going straight to the TV. Will this work with the 4K signal?
    Victor A on May 27, 2017
    BEST ANSWER: Thank you for your question. This unit will not support 4K picture. However, we do carry Product # 13348 that will support 4K picture and also have a optical output. Though the optical output will only support DTS 2 channel or 5.1 channel audio. I hope this helps.

    Works perfectly
    Most AVR Receivers cannot play a digital input (eg HDMI) to both Zone 1 and Zone 2 simultaneously. In my case I want to have an AppleTV (4th Gen) play music in both zones simultaneously. This allows the AppleTV to plug into the AVR with HDMI for Zone 1, and also have an analog audio input into the AVR to be played to Zone 2.

    No luck for passing Roku 3's Netflix DD+ to DD AVR
    It's hard to give a rating to this unit. I guess it does what it claims to do so it should get a 10, but it didn't do what I was hoping it would do after reading other reviews. I recently purchased a Roku 3 and wanted to stream Netflix through it. Trouble was, my AVR is a Denon 3801 from ~1999 that doesn't have HDMI. I was hoping this would let me send the DD (or should I say DD+) to my receiver for decoding. My receiver doesn't have a DD+ decoder, just a DD, but from what I've read DD+ was supposed to be backward compatible. Well it didn't work for me, I tried 3 different optical cables, and even tried a coax. I was hoping to spend ~$50 rather than drop big bucks on a new quality receiver, but it looks like I have to give up the ghost. Too bad, that Denon still sounds great with OTA and Blu-Rays piped through it. Hope this helps somebody out with their decision.

    PROS: Does what it's supposed to

    Quick delivery

    Close but not quite
    I bought this so I can get dolby true HD out of the coax or optical connection. I need to split the audio to my preamp and pass the video to my HDMI matrix. This doesnt decode those audio streams, only passes them through the HDMI connection. I will have to return this and get a HDMI splitter that supports Dolby true HD.

    PROS: Small and easy to hook up

    CONS: Does NOT support dolby True HD/ DTS-HD Master audio output on the coax or optical connectors. Will pass them through the HDMI. This should be more clear on the description.

    Response from Monoprice
    Hello Steve,

    Thank you for your review on PID 10251! Regarding Dolby True HD and DTS-HD Master Audio, you are correct in that these audio codecs will only be supported via HDMI. Unfortunately, digital coax and optical Toslink are not able to provide the bandwidth needed to transmit these high-definition audio codecs at all and would only support two channel uncompressed PCM or compressed 5.1/7.1 audio. Only HDMI would be capable of handling Dolby True HD and DTS-HD MA even with other brand products.

    Should you have any questions regarding our products, please feel free to contact our tech support team via live chat, phone, or email and we would be happy to assist you. My apologies for the trouble and I hope this helps!

    I bought this to be able to get 5.1 sound to my receiver even though one of my TVs only supports 2.0 pcm. The a-b switch on the back works great but if I want to watch the TV that doesn't have the receiver and only supports 2.0 it only can receive sound information on channels with 2.0 soundtracks or if I switch it back to A and force a 2.0 output. I ended up buying an optical to analog decoder on amazon as there was no equivalent part available from monoprice. This part could be perfect if there were a second version that included the DD and DTS decoder built-in.

    PROS: Does everything it says it does.

    CONS: It would be useful if there were a version that converted dolby digital and dts to 2 channel analog.

    Worked great with TiVo Mini + Samsung TV + Sonos Playbar + Surround Sound via Sonos Connect:Amp
    Samsung TVs generally don't output Dolby Digital from their optical audio output (Toslink) *if* the source is connected via HDMI (lame, I know), so I needed this Monoprice (reviewed) part to go between the TiVo Mini and the Samsung TV in order to get a Toslink connection to the Sonos Playbar that did contain Dolby Digital (not simply 2ch).

    The one change I made to the arrangement was instead of using the power supply (supplied) for the Monorprice part, I connected a USB-to-power adapter from the Samsung TV. When we used the power supply that came with the Monoprice part, after turning off the TV, the sound from the TiVo Mini would continue to play out of the Sonos Playbar, because the Playbar continued to receive audio information. By connecting the USB-to-power cable from the Samsung TV to the Monoprice, the power would be cut whenever the TV turned off, and this perfectly sorted out the issue. FYI, this Samsung TV had (2) USB inputs, both of which supplied power whenever the TV was turned on – one with 0.5 amps, another with 1.0 amps, and we used the higher amperage output.

    Connecting old technology with new technology
    I needed to connect my receiver without hdmi inputs to a pc with an hdmi output. And it has performed flawlessly. I had an issue with your shipping time. I paid for 3-4 day shipping and I received my purchase in 6 days. When monoprice offered "free" shipping I also received my purchase in 6 days! Sounds fishy guys you may want to work on that.

    PROS: Works great!

    CONS: None

    Listen to Google Play Music with Chromecast without having TV on
    I can now listen to Google Play Music with Chromecast without having TV on. This is great because running the TV while using Chromecast to listen to music through Google Play just wastes energy. I connected the 3.5 mm audio coming out of the adapter to an aux input on my audio amp. Works great!

    PROS: Small footprint. Lots of audio output options. Allows you to use an old audio amplifier that has no HDMI inputs.

    CONS: None, other than it's a bit expensive, but not too bad.

    A Queation for Monoprice
    It appears this product suffers from the Netflix Dolby Digital Plus curse as everything other route I've tried or considered. I have a 5.1 Vizio Soundbar that when fed Netflix (DD+) will produce no sound. You must switch Netflix to 2-ch Stereo to view Netflix on Roku. Amazon Fire TV has the same problem but it has a DD Optical Out that will give 5.1.

    Is their any product that will downcode DD+ via HDMI to DD via Optical so a non-DD+ capable soundbar can play sound.

    Perfect on my Roku 3
    I wanted to pull stereo audio onto RCA jacks off my Roku 3 and it worked perfectly. As others have noted, if you want to stereo signals out of the unit, it must be stereo coming in there is no digital conversion. But this works fine for my needs.

    PROS: * Easy setup, just worked

    CONS: * Only pulls off stereo audio onto stereo output

    Works perfectly with older Roku
    I got this to connect an old Roku 3 to an hdtv and a 25 yr-old stereo amp which I still prefer over a newer receiver I bought last year. The hdmi out connects to my TV and the analog audio out connects to my amp. It's a perfect solution to a Roku with only an hdmi out. Beware, however, that the NEW Roku 2 and 3 which recently came out are apparently not compatible with these devices. So say review comments at Amazon.

    PROS: Works just the way it's supposed to with my old Roku 3.

    CONS: None
