M-Live M-PEN 2 Wi-Fi Dongle is a USB accessory for B.Beat or DIVO series players from M-Live. This dongle plugs directly into their USB port and serves the various functions of the two devices. On B.Beat, it allows the Prompter app to connect to any smartphone or tablet on stage and display synced lyrics and/or chords in time with the backing track. In the DIVO device, it provides the same function, as well as the ability to connect to the Internet to download the necessary backing tracks.
