The system TWG designed for MGM National Harbor is made up of JBL Control Contractor Series speakers, with approximately 500 Control 328CT in-ceiling loudspeakers and 70 Control 312CS in-ceiling subwoofers installed in the casino. The complete HARMAN solution offers exceptional sound quality, flexibility and ease of operation, enabling the MGM casino to control the audio for different gaming areas and easily expand the system as their needs evolve. Leveraging years of experience with casino audio systems, Technology West Group deployed a complete HARMAN networked audio system consisting of JBL Control 300 Series speakers, Crown DCI Series amplifiers and BSS networked audio systems. With MGM, we made an effort to solve those issues.” The Solution: The table games need different volume levels from the slots, and even within the table games area, the customers playing blackjack might want to listen to different volume levels than the customers playing the craps tables. When we really dig in, it comes down to sharing speaker zones between slots and table games, or transitions between high ceilings and low ceilings. “We run into a lot of property owners who hate the way the audio system sounds. “In older properties, you’ll often see traditional audio system designs that don’t work very well for the way a casino typically operates,” said Richard Reisig, General Manager at Technology West Group. Furthermore, casino floor layouts are often rearranged annually, and any adjustment to the audio system usually requires major renovations. For example, the music near the poker tables needs to be much quieter than the slots area, since the poker players need to concentrate and communicate clearly during games. 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.
