The following troubleshooting tips can help diagnose and correct most concerns with the 512. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip. If the problem persists and your speaker is located within the US, please contact customer support and provide us with the following information: serial number, purchase information (when and where), your current shipping address, and the results of each step. If your speaker is outside of the US, we are unable to offer product services, but please use the below link to contact the distributor in the country where the speaker is located. Since the distributor is who will be assisting you from this point on, they will be able to let you know what options you may have. Be sure to still include your full name, where and when your 512 was purchased, the serial number, and your current shipping address when contacting any distributor:


If the power button on the 512 is not illuminated, then try these tips:

  • Make sure the 512 is charged. If not, you’ll need to connect the 512 to an external USB AC adapter with the supplied USB cable.
  • Press and hold the power button on the top of the 512 until you hear the power-on notification

512 troubleshooting tips – Bluetooth

  • If you haven’t already, power-cycle your speaker by turning it off and back on.
  • Be sure to test your 512 using the Aux input instead of Bluetooth.
  • If your 512 is already connected to a device via Bluetooth, the Bluetooth Pair light on the top of the speaker will be on and solid. To disconnect a device that is currently connected to the speaker, press and hold the Pairing button on the top until you hear the “pair mode” notification.
  • Check to make sure your source device (computer, tablet, phone, etc) and all audio apps are running the most up-to-date version of software available
  • Try playing audio from more than one application on your phone/tablet, or computer.
  • Try disconnecting from and forgetting the 512 through your device’s Bluetooth settings and then re-pair to the 512.
  • Try using a different device with your 512 to see if the issue follows.
  • If possible, try your 512 in a different location to see if something is causing an issue in the current setup. Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speakers may be causing interference in your setup.

If you are experiencing an audio-related issue using the Aux input, try these tips:

  • Check to see if the Aux button on the top of the 512 is illuminated. If not, press the Aux button.
  • Check that the cables from your audio sources to the speaker are properly connected. Confirm this by unplugging the audio cables and then reconnecting.
  • Verify that the volume control on the top of the speaker is not turned all the way down.
  • Make sure the volume is up on your media players, internet radio, master control, device volume, etc. and that the balance control is centered.
  • Decrease the volume of the input audio source and increase the volume of the 512 speaker.
  • Try using different audio input sources and/or devices to see if the problem follows.
  • If your input source has its own EQ (equalizer), please make sure the low end is at a moderate level as having too much bass in your signal can cause distortion.
  • Move your speaker to a different location to see if something is causing interference in the current setup. Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speaker can cause interference.
