Powernode N330 subwoofer rumbling when turned on

When the Powernode N330 is turned on (out of standby) the subwoofer makes a rumbling sound. In 10 seconds the rumbling sound of the sub decays and is gone, after that the sound is ok.

At first I thought it was the power supply of the sub. I unplugged both the amp and the sub and first plugged the sub back in. Nothing happened. After I plugged in the amp the rumbling sound came back, so I ruled out its the sub. On this forum I read other related issues with the subwoofer-output on the amp. What to do?

Another issue I have quite often is sound drop-out of around a second of the main speakers in the first minute of music and TV-sound playback. This issue occurs when connected via wifi and via ethernet.

Please advise.

    Another user frustrated with the subwoofer rumble. There’s enough of a signal when not playing music to prevent the sub from going into standby. After playing music for a time it sounds like it goes away. But a few minutes after pausing is back.

    I think it goes without saying, same issue here started after working great for a long while…. SMH! I’ve just started turning my sub on after the fact but, will monitor the thread because it’s BS at the price point; especially with almost no one in this chat getting resolution.

    **Any updates on this yet Bluesound???

    Powernode -> SVS4k

    Hi Seth and Matthew

    Read through the thread as many of these issues reported will vary depending on your situation. For a full diagnosis though, please feel free to select Settings, Send Support Request in the BluOS App so our Support Crew can tailor their answers to your specific sub or identify a possible issue with your POWERNODE. 

    Seth mentioned an SVS brand sub-woofer. These Subs do have a reputation for being extremely sensitive to impedance issues. Our Support Crew has a trick or two up their sleeves.

    Thanks Tony, I will give it a go running through the app and see what tricks are available. I swapped in an old Klipsch sub that still gave the same result, only with a little less sensitivity on impedance characteristics like you mentioned. Thanks.

    My powernode gave also a rumbling sound as mentioned before. The powernode was send for repair to Bluos. They repaired the sub out. Now the powernode works fine. The only downside is, that it toke 8 weeks before I had the powernode back.

    I currently have 451344 open for this same issue - bluesound already replaced it one time and now the replacement they sent is doing the same thing! I never heard that this required a hardware repair so interested to see how they handle my support request for replacement this time around…

    I am experiencing the same issue with my subwoofer, especially while listening from the HDMI ARC input from a Samsung TV. The subwoofer constantly rumbles and produces unwanted sounds, but this doesn’t happen when using Spotify Connect.

    I’m using a REL T Zero MKII.

    The only way to temporarily solve the issue is by switching off the sub :/
