JBL Horizon

Yes, if a telephone is connected via Bluetooth to Horizon, this is possible. When adjusting the wake-up timer, there will be an option to select various wake-up tones, or Bluetooth sound. Select Bluetooth as source, while the telephone is playing the music stored locally, or streaming what you want as wake-up music. When the wake-up adjustment is finished, music will be playing over Bluetooth through the Horizon. Press Pause on the source telephone, or press the round selector button (between the two arrow-buttons) on the Horizon to pause the music. Now the system is ready to wake you up with Bluetooth music. When wake-up time arrives, Horizon sends a Play command to the telephone, and music plays via Bluetooth. You can use music that is stored in the phone, use Spotify or play from the cloud. This has been tested with both iPhone 6 and Samsung S6, and should work flawlessly.

Since the internal wake-up signals and FM radio do not permit adjustment of the wake-up signal volume, it may be desirable to use an alternative signal source. Connect a smartphone with Bluetooth, and set the Horizon to use the Bluetooth input for wake-up sound. If you reduce the output volume on your smartphone to a suitable level, you will experience a much lower signal volume when Horizon activates the smartphone through Bluetooth when the wake-up time has been reached. With a smartphone, both music from the phone's internal memory, its FM radio, web radio or streamed music may be used. If you want to wake up to a certain song, select the desired tune on the phone, and when it receives the Play command from Horizon, it will begin the right tune.
