    Hi Keith,

    The link works for me. Anyway, down below is a cut and paste of the response.

    If "Subwoofer" in the BluOS app is set to off, the L/R main speakers get the full range signal.

    If "Subwoofer" in the BluOS app is set to on, the L/R main speakers get a high pass filtered signal, depending on the crossover frequency, 80Hz, 100Hz, etc, that you have set in the BluOS app.

    The low pass filtered signal, eg with crossover at 80Hz, 100Hz, etc,  is constantly sent to the subwoofer output, irrespective of the "Subwoofer" setting in the BluOS app. There is no way to disable the subwoofer other than to unplug it!

    Response from Bluesound.....

    Hello Dave​​,

    Thank you for contacting Bluesound​ Support.

    I hope you are well during these times, and I sincerely apologise for the delay in getting back to you as we have experienced a higher volume of requests due to CV-19 isolation strategies worldwide have more people at home enjoying their systems.

    Yes -- if you have Subwoofer Enabled in the BluOS app, the high pass filter will be sent to the speakers connected to the POWERNODE and the low pass will be sent to your sub over the SUBW OUT on the POWERNODE. 

    If you want full range on your speakers, set Subwoofer to No Subwoofer (you will still get an output out of the SUBW OUT on the POWERNODE even when Subwoofer is set to No Subwoofer)

    Hope this helps!

    Wishing you well,
    Sam R.,

    Hi Keith,

    If I can help....the subwoofer setting simply turns on or off the crossover filter for the main L/R speakers.

    You set the high pass crossover frequency according to your main L/R speaker's requirement.

    The low pass subwoofer signal is always sent to the subwoofer, irrespective of the on/off status for the main L/R speakers.

    That's how it was explained to me a couple of months ago....see link below.

    Hi Dave,

    Thanks for you assistance.  The link you have attached doesn't work.  Gives the following error:

    OOPS

    The page you were looking for doesn't exist

    You may have mistyped the address or the page may have moved

     

    So if the subwoofer is set to off, do you know what signal level is sent to the sub? e.g. 80hz?  Would this also mean that the L/R speakers get the full range and the sub is also sent a signal at some preset setting?

    I think any reasonable person would conclude that setting the subwoofer output to "off" should stop sending signals to the subwoofer. In my setup the subwoofer is shared between systems and I actually need the Powernode to stop sending a signal to the sub when i'm not watching movies. Ideally this setting would be applied to whatever source is being used (e.g. subwoofer on for movies and off for Tidal), but BlueOS has much bigger problems to address first.

    I agree Rodger.  I would prefer it if when the subwoofer is set to Off then the PowerNode was not sending any signal to the subwoofer.  I can't understand why this would need to happen.

    Hi Rodger,

    I totally agree with you! While the overall concept of BluOS is good, there are a number of aspects which seemingly have not been well thought through in the software specification. This has the hallmarks of the software being coded by someone who didn't really understand how the system was going to be utilised in practice.
