Example System: Sound Bars
The MH2-HD does more than play media in this engaging sound bar demo - it coordinates a complex
audio demo with video and lighting effects. Customers can audition sound bars, select media, add
rear speakers, compare TV speakers to sound bars, and adjust volume. Push a button on the right to
hear a sound bar, which also triggers the rst media le to play, and the shelf to light up. Lights under
the shelf also highlight the selected subwoofer. The user selects media using a small touch screen.
The rear speakers are powered via a smart amplier that tracks volume control with the selected
sound bar. After a period of inactivity, the display returns to a silent state, ready for the next customer.
