For the best sound quality when using your PA-360 speakers with an external source like a smartphone, it is important to follow these steps:

Maximize the volume of your smartphone:

Set your phone's volume control to the maximum level. This enhances the Bluetooth signal sent to the PA-360 speakers.

Prevent automatic standby mode:

A volume that is too low may cause the speakers to automatically switch to standby mode after 20 minutes. This occurs because the Bluetooth receiver might detect that no active signals are being received.

By following these steps, you can ensure that your PA-360 speakers operate optimally and minimize the risk of unwanted interruptions. This way, you always enjoy the best sound quality when streaming music via your smartphone.
