Good evening, everyone.
 
I just purchased the Nu Audio card for its RCA output and connected this to a stereo amplifier. I would like to add a powered subwoofer to the system, and am not sure how I do it. Is there a way to connect the subwoofer directly to an output on the card?
 
Many Thanks

    No idea on this one, I went through the manual and FAQ for ya too. You will have to ask EVGA about that one and you can tell them I said its not mentioned in any of the FAQ or manuals to save them the time. If your hooking up a separate amp deck, then hook that to the card and the sub to the amp... not the nu.

    Thanks, much appreciated. I will give EVGA a call. I am guessing I am going to have to get a stereo (2) to double stereo (4) splitter or cable for the RCA port, which I was hoping I wouldn't have to do.

    RCA is analog. It's nothing new or exotic. Hook the woofer up through your existing amp's low-level output (if available), or split it off the RCA jacks on the card, just like you would have any other decade. You could also use the SPDIF output on the card, but that would make the card completely pointless and unused; since the digital output from the card is unmodified digital output straight from your CPU (which you could have access to identical sound from your motherboard's digital output (if available) or using a $5 sound card from years ago).

    And it also doesn't appear to come with a dedicated analog subwoofer channel output.

    My powered subwoofer is connected to my Speaker System that is connect to the NU Audio Card using the S/PDIF Out Port.

    And makes your quote to me absolutely pointless as well and even more so not owning your own NU Audio Card.

    RCA is analog.

    Not True, now had you said that the RCA on the NU Audio Card is analog then yes would be correct.
    Most if not ALL Subwoofer connections on Receivers are RCA Based.
    Most if not ALL Have A Digital Cable Connection on Receivers are RCA Based as well as S/PDIF.

    To be fair, the SPDIF output might sound better than the analog output. The SPDIF output is the sound the artist intended, has no added distortion, and no added noise or interference. But that would mean that the entire NU Audio card is pointless, huh?

    Digital RCA? You mean Digital Coaxial? RCA is analog. Usually you call it Digital Coaxial if using digital signaling. The difference in name is to reduce the confusion.

    The point is that a digital to analog conversion has to occur at some point, and using spdif output means that you're relying on what is probably an inferior DAC in the stereo unit, and limited in stereo choices.
     
    As an update, I used  RCA splitters on the output of the card, and the setup is sounding bloody effing fantastic. Of course, I can't really say if this is because of the EVGA sound card. It sure is whisper quiet and noise free though.

    Both are Still RCA Connectors.

    Sure, but they are purposely called different things to avoid confusion. RCA is analog. Digital Coaxial is digital.

    Hi, I have my Nu Audio connected with a powered sub and powered studio monitors, I have the Mackie CR3's with the Samson S10 Sub, so this is how you do it, you need a SUB with line in and line out RCA plugs, go into the sub from the studio monitors via RCA and RCA out to the sound card, this combo works and the cr3 and the samson s10 are amazing together, really good sound. Good luck!

    RCA or phono plug is neither analog or digital. It is simply the name or type of the connection not the type of signal that is carried. You do not call an RCA or phono plug cable a 'digital coaxial cable' just because the signal is digital. It is still an electrical signal carried over a conductor. I would certainly be confused if someone, looking at a pile of phono cables said...
    hand me one of those 'digital coaxial cables'. Yeah...where did YOU, ever hear that?

    If the output is digital, the output connector is called "digital coaxial".
    The connector is the same. The cable is similar. The name is different. Both types of connectors are RCA-style RG59, but "RCA cable" or "RCA connector" describes an analog signal. "Digital coaxial" describes a digital signal application. It's pretty much the same thing, but the name is purposely different in order to describe the signal and the application.
    Feel free to use Google.

    A "digital coaxial cable" which you can buy right now:
    https://www.amazon.com/Mo...io-Video/dp/B003NMVG64
     
     
    Analog RCA Audio:

    Analog RCA audio is usually red and white and usually has two cables combined together by the insulative sheath.
     
    Digital coaxial audio and/or video:

    Digital Coaxial uses the same RCA-style RG59 connector, but is usually not red or white and does not have more than one cable combined.


    Actual product connector photos:

    See? Third arrow on the bottom, see how it says "coaxial" and "digital", and NOT RCA?

    And another:

    See? "Coaxial" and "digital" on the left, under the salmon colored cable.
