How to Resolve SUB 10/ SUB 12 App Connection and Control Issues ?

If you experience problems with the Ultimea App, such as disconnection, slow connection, or custom EQ settings not taking effect, please refer to the corresponding situation below.
 
  1. App Disconnects After a Long Period Without Playback
When the USB 10 is set to AUTO power mode, the subwoofer automatically enters standby after 15 minutes without audio playback, which causes the App connection to be disconnected. When playback resumes, the subwoofer will automatically wake up and reconnect to the App. If you want to keep the App connected continuously, open the App settings and extend the standby time, or switch the power mode to ON.
 
  1. App Takes Longer to Connect After a Factory Reset
After restoring the USB 10 to factory settings, the first App connection may take more than 25s. Please wait patiently for the connection to complete and do not perform other operations while the factory reset is in progress.
 
  1. EQ Settings Do Not Take Effect
If you adjust the Frequency settings under Custom EQ in the App but the subwoofer's sound does not change, please first check whether the EQ master switch is enabled. And then adjust the frequency bands and other EQ parameters as needed.
 
  1. There Is No RESET Button in Custom EQ
For firmware versions earlier than V19, the Custom EQ interface does not include a RESET button. If you want to restore the EQ settings, you can either:
  • Tap Restore Default EQ in the App to restore the default EQ settings;
  • Press and hold the PHASE button for 8s to restore the device to factory settings and reset the EQ settings.
 
If the issue persists after following the corresponding steps above, please contact customer service at support@ultimea.com
