    I ordered this, but actually need the optical in to coax out converter. I'm wondering if they are the same product, meaning will the sound travel either way?

    Monoprice S/PDIF (Toslink) Digital Optical to Digital Coaxial (RCA) Audio Converter
    Monoprice S/PDIF (Toslink) Digital Optical to Digital Coaxial (RCA) Audio Converter
    Monoprice Digital Coaxial (RCA) to S/PDIF (Toslink) Digital Optical Audio Converter
    Monoprice Digital Coaxial (RCA) to S/PDIF (Toslink) Digital Optical Audio Converter
    BEST ANSWER: Thank you for your question. The signal will only transmit in one direction. The converters will indicate which port is for input and which port is for output.

    The Digital Coaxial (RCA) will be the input and the S/PDIF (Toslink) will be the output on PID 2947.

    The S/PDIF (Toslink) will be the input and the Digital Coaxial (RCA) will be the output on PID 2948.
    What voltage does the adaptor run on?
    A shopper on Sep 27, 2017
    BEST ANSWER: It comes with a 12 VDC output switch mode voltage regulated power supply with 120 VAC North American power cord.
    Will the coaxial out be in stereo or mono?
    Corey B on Apr 13, 2018
    BEST ANSWER: Both the input and output are S/PDIF digital signals. The input is S/PDIF Digital Optical and the output is S/PDIF Digital over Copper (Coax cable with RCA/Phono connectors). S/PDIF carries a stereo digital signal. You can use only one of the two channels, of course, for mono. BUT the RCA output is not an analog signal, it will have to be attached to a S/PDIF digital input on another device!
    How do I hook it to my cable box , tv, DVD and sound bar? I know I run the optical cable to the plug on one end, but what do I plug in the other end?
    A shopper on Sep 5, 2018
    BEST ANSWER: This is if you have a toslink optical output from your dvd, cable box, game console etc( square-ish looking plug) and you have run out of toslink sockets on your reciever, and all you have are coax optical inputs( round rca plug - dunno if you need a special cable or not, used monoprice for both. I’m assuming your tv/sound bar is the final output, and there is no reciever in between. So- look at the back of your dvd player/ cable box. There should be a digital audio out, if you’re not using HDMI for connecting, your sound bar/tv may have a digital audio IN, either toslink or coaxial. If you wanted dolby digital/dts and you couldn’t use Hdmi to whatever, you could use this. Hope that helps..jb
    How long is the Power Adapter Cord? Thanks.
    Lex G on Apr 18, 2017
    BEST ANSWER: The power adapter cord is 6 feet in length.
    Is there a light indicator?
    A shopper on Jan 23, 2017
    BEST ANSWER: No there isn't a light indicator. This product has worked perfectly for me. I ran a a toslink cable from an Apple TV to the convertor, then a digital coaxial cable on to my DAC. The DAC's toslink connection was being used by my Macbook, thus the need for the convertor. This device did exactly what it's supposed to do and performed flawlessly.

    Great way to convert optical to coaxial
    Bought this because my Philips soundbar only had a coaxial audio input and my PS3 had an optical toslink output. Hooked it up in 30 seconds and wahla! Worked great. Audio from the soundbar, via the PS3, is great. Make sure you get the correct input/output device. It would not have worked if I got the coaxial input and toslink output. I have noticed that both directional devices are available, so choose the correct direction of your conversion.

    I was about to give up on my Home theater because it only had digital input(not optical) and my xbox360 and ps3 didn't sound like the movies I play from it.Then I start the search in this wonderful site called monoprice. This are the items that I bought for my project,item 2946, 2948, 6303,6272(3), when I finish the operation and try to get out from the web of cables,the sound that came from my 360 and ps3 were gorgeous.I give all the items a 10 for quality,performance and price. My recommendation, if you have an old Home theater,don't place it in your kids room to buy one with HDMI,just buy this combo and you will be satisfied. Thanks monoprice for this wonderful items.

    Does the job at a great price.
    It does what it's supposed to: converting an optical SPDIF digital audio signal to a coaxial interface. And it's cheap. I use it to take the Dolby Digital optical from my Xbox 360 into my 10-year-old Altec Lansing AD880 speakers that only have coax input. I also occasionally use it plugged in to the mini-optical output of my MacBook Pro (via an adapter: product ID 2671).

    But it has a few issues. It's an active signal conversion with means it requires power, which means there's a small DC transformer that must be plugged in. I've also had problems with it putting out loud glitches or noise when there is no input signal (when my Xbox is off). It seems to occur when there is a fluctuation in the line voltage (power surges, or when i turn off the light switch in the room). Unfortunately for me, that means i have to either unplug the transformer, or the cable to my speakers if i'm not using the adapter.

    + cheap
    + works

    - bulky power transformer makes for sloppy installation (cables coming out of 3 sides)
    - output signal glitches with blips in electricity

    optical TosLink to coaxial (RCA) digital converter
    This is actually the second one of these that I have bought from Monoprice. The first one I bought several years ago is still in use I simply had a need for a second one and once again this does the trick! If you have device(s) which put out only TosLink as the digital audio and need to convert it to RCA, get this device! I'm very happy with both of mine. I have both of mine hooked to a "smart strip" so they are on only when my TV / home theater system is on. I would recommend that sort of setup rather than keeping these devices on 24/7! Again, I'm very happy with mine. Thank you Monoprice!

    How can you go wrong with monoprice
    I have heard on several podcasts about monoprice and decided to give it a try when I needed to hook up my old digital speakers. Needed to go from Toslink to a coaxial and found this unit and a real steal of a price. If you need to go from a Toslink cable to a coaxial rca digital cable this will solve your problem.

    PROS: It works perfectly and is a really low price. Very small and compact unit that can fit in your hand.

    CONS: None

    PROS: Works great. Now my LED TV (Toslink) and my Entertainment System (Coax) works. Able to amplify the volume without and issue.

    CONS: It would be great if they have a 110 to 240V power adaptor.
    Jrrry's Review of Toslink to Coaxial Converter
    The shipping was prompt. Product arrived in excellent condition. Product works fine. Initial observations indicate that product is high quality. Price is very low. I didn't expect to get such high quality at a very low price.

    Just what I needed
    I needed this to hook up a new Samsung tv that only had digital audio out to a Philips soundbar subwoofer that only has coaxial digital input. Hooked it up and it works great! Sound is so much better now rather than the RCA audio I had to use before this.
    February 14, 2010

    PROS: Worked great for me, allowing us digital surround sound from a 2nd source (satellite & HTPC) w/o having to replace existing Audio Video Receiver. Very low power: description says wall wart is 3000ma...it's actually 300ma, which I'm sure is plenty based on the Converter operating cool-to-the-touch.

    CONS: Not the product's fault, but it the extra cable + wall wart added to the "rat's nest" behind entertainment center...Then when satellite digital audio went out temporarily, I thought it was the new converter.
