    Hi Scott

    There's a lot to go over here... I am going to give you the quick and dirty answers... for more details select Help, Send Support request in the App or e-mail us at support@bluesound.com and we will be happy to give you more granular answers; 

    Your wish list in order;

    • It's all actually available in Settings at the bottom of the Navigation Drawer, we add a Audio Settings Shortcut in the Player Drawer to help for those quick volume control needs.
    • We can't, Apple won't let us... only if the App itself plays music, which it does not
    • We continue to work with Pandora and SiriusXM to add them along with the other music services we do support but you have a 2i model - why not Airplay Pandora to it...
    • Airplay it
    • The Player auto detects if it is Analog or Optical so it will show up as detected in the App. When we launched the POWERNODE 2i we added a second input to THAT model (over the Powernode and POWERNODE 2) as consumers kept coming to us with a TV and Phone Pre-amp stating they wanted both, but it really was just the POWERNODE they were asking this for. Probably because the NODE was going into an integrated amp more often than straight into a Poweramp
    • (Last two bullets) If the 24/192 Burr Brown DAC (which punches above it's weight many find) isn't what you are looking for, connect the DAC between the NODE and the Amplifier via COAX or Optical Out. DAC as a source isn't an ideal setup...

    OK for most of these. I had found that the volume control button wasn't; available as a result Apple's "largess"...

    It turns out I have been using Airplay for Pandora and, if I want, iTunes. The down side of that is simply having to change apps.  I copied my iTunes library to the NAS, so it plays from there through the BlueSound app. The only issue is when I add new iTunes songs, then I have to update that library too. Not having the iPad content visible in the BlueSound App is a pretty big negative. Hopefully someone can get Apple to come to their senses. 

    On another note, I can also play from the iPad through an Airport Express and pipe the audio from the Airport Express to the Optical_In port. However, that approach has a serious reduction in volume, so someone may want to look at how the volumes are matched between those inputs. 

    IMPORTANT: I think you may have misunderstood my DAC request. As you note, the DAC in the Node 2i is pretty good, and it is integrated with the app controls, which is even better (for example the volume range adjustment that scales the slider when you set the maximum and minimum volumes in Settings)! What I want to do (see the diagram I posted above) is to get the digital stream before it gets to the DAC (your current Optical_Out), process it through my DSP, and then put it back in so it goes into the DAC and out the analog ports of the Node 2i. So, this is an optional DAC_IN for when you use the Optical_Out for off board processing, but still want to use the onboard DAC.

    Airplay 2 how to; https://support.bluos.net/hc/en-us/articles/360013227054

    As for your DAC Request - but we do that for you already internally so you don't have to. I will tell you we don't up sample or down sample. If you want to know what's going on though, select Technical Info in the context menu of the now playing track in your local library to see what the bit rate and format is.

    If you really really want to, you can try using the Input once you free up the AirPort and have Airplay working but again, not sure what you gain by doing that.

    Hi Tony; See my edit to my reply. Turns out I was already using Airplay. Works fine, just means you have to leave the Blue Sound App, since the iTunes content on the iPad doesn't show in the app. I get the reasons for that now. 

    Not sure I understand what you mean by: "As for your DAC Request - but we do that for you already internally so you don't have to. I will tell you we don't up sample or down sample."

    I use an external DSP for room equalization, so I'd like to loop the digital signal out of the Node 2i (i.e from the Optical_Out port), and after it's processed, I want to loop in back INTO the Node 2i so the DAC can act on it. If you don't resample, then the DAC must be able to adjust to different bit rates and depths. If that's the case, then my DSP will need to do the same. What it does is resample everything to 24/192, and processes it, so everything that comes into the DSP would end up back to the DAC at 24/192. 

    As it currently seems to work, of you come out of the Optical Out port, then you have to use your own DAC outside the Node 2i. 

    I had originally tried routing the DSP output back in the Optical_In port, but that doesn't work because that port has to be selected in the App, and when it is, then the NAS can't act as the source (and the DSP is trying to use the Node 21 as the source...). 

    As another way of describing the entire thing is to consider that the Node 2i has two elements: 1) The source and player functions (network shares, selection and control of thepslayback, etc; and 2) The conversion from digital to analog (with some volume control functions, which I assume are done in the DAC). It would be nice to be able to use those two parts independently. SO you can get the digital source as it is being played (your existing Optical Out port), and then pass it back IN so it can then be converted to analog by the DAC.

    This will cause distortion and additional jitter. This is also not what we are trying to provide for the consumer. Our goal at Bluesound is to set it and forget it, sit back and enjoy great sounding music effort free. Let your ears be the judge.

    That's what #LivingHiFi is about.

    If going out of the Node 2i is such a bad idea (and if your objective is a totally plug and play experience), then why have the Optical Out port at all? 

    Seems there is no difference between using the existing Optical Out port and an external processor/DAC, or using an external processor and the Node 2i DAC...other than the lack of access to that input of the Node 2i DAC. 

    My ears have been the judge. Room equalization creates an entirely new dimension to the finished product, and, while I think the Node 2i is a nice unit, it would be just that much more flexible if it had a usable Optical I/O, as opposed to the half way approach that you have now.

    Hi Scott

    Sorry for the confusion The Digital Outputs are there for consumers with high end DACs that wish to bypass our internal Burr Brown 24/192, that's perfectly fine. The issues I suggest are caused by plugging DACs INTO a Bluesound Player and then going out the analogue as you are now filtering your audio through two DACs which is not a good idea and can possibly cause undue distortion.

    I hope that clarifies it.

    I still don't think you are following me, or perhaps I don't understand the Node2i architecture. 

    As I understand it, the Digital_out, pulls off the digital stream just prior to the internal DAC. This is so that users can send that stream to an external high-end DAC, as you noted. 

    So, what I would like to do is take that output, perform additional digital processing on it (all in the digital domain), and then input that processed stream back into the Node 2i right at the DAC, instead of using an external DAC. 

    Here are a couple of diagrams. The first is a simplified architecture of the Node 2i. The second shows the suggested change. As you can see, this is really just allowing the user to externally process the digital stream before it goes back into the DAC

    I fully understand. It's just not available in the NODE 2i.

    That being said our good friends at NAD do have a couple of products that run our BluOS Firmware and allow for internal DSP adjustments via DIRAC in their line up with the NAD C658 Streamer or the just announced NAD M10 Master Series Amplifier.
