Casino staff have no way of adjusting the volume for different gaming areas, so the music may be too loud in one area and too quiet in another. This approach provides even audio coverage across the entire gaming floor, but also poses several problems. Historically, casinos typically relied on a traditional audio system design made up of a series of high-powered amplifiers driving a chain of 60-70 speakers. MGM requested a networked audio system for the casino that would enable flexible and independent volume control across a wide range of audio zones, while also requiring minimal training and maintenance for staff. MGM National Harbor is a recently opened resort and casino.
