- 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. For Mac OS users, be sure to check the app store to see if there's a newer version of Mac OS you could be running.
- 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.

- Check to see if the Aux button on the top of the 512 is illuminated. If not, press the Aux button.

- 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.
