Thanks to Bluetooth™ connectivity, the Alto Professional TX Series ensures that users can get their PA system up and running completely cable free. This feature is perfect for any application that requires two simultaneous sources of audio, such as a microphone and background music running at the same time - a wedding MC announcing the bride and groom’s first dance over music, a fitness instructor leading a spin class while energetic tunes pump in the background, a busker playing a long to a backing track, etc… In addition, the TX Series’ powerful Bluetooth™ True Wireless Stereo (TWS) connectivity allows users to run two units in conjunction with one another without having to purchase any extraneous equipment or cables.
