The JBL PRX ONE is an all-in-one powered column PA featuring an acoustically optimized column array with a 7-channel digital mixer, a full suite of professional DSP, Bluetooth functionality, and the JBL Pro Connect universal app for control. 
Today, we’re going to show you how to set up your speaker for streaming audio over Bluetooth. With the speaker powered on, press the menu button to access the main menu. Scroll to the bottom of the main menu to find the Settings menu, and select it with the menu button. The first option of the settings menu is “BT Audio Pairing”. Select this using the menu button. While this loading screen is up, our speaker is now discoverable on our phone or source device as “JBL PRX ONE”. Select it to pair the device to the speaker. The PRX ONE will show you when the pairing is successful, and a light will illuminate under the channel 7 knob. Right out of the box, the PRX ONE’s gain will be set to -100db for channel 7 and needs to be increased for our music to be heard. To adjust the gain of this channel, first press the channel 7 knob to bring up the Channel 7 menu. Then use the Channel 1 knob to adjust the gain for the Bluetooth channel. We recommend that you begin playing music from your phone or source device before you start adjusting the gain setting. From the channel 7 menu, press the back button once to return to the home screen.
