For this install we had limited space in a great room media closet so we installed a custom rack that pulls out for easy service. The Sonos audio system connects to the speakers throughout the house to that is controlled from a smart phone or device. The Audio Video receiver is also located here for the great rooms 5.1 surround sound system. The media closet has cooling fans built in to allow the warm air to exit the closet when the door is closed. The RF remote controls the surround sound system in the medina closet with the doors shut. The media closet rack is from snap-av and is designed to pull out and articulate so the service technician can work in the media closet and rack with ease. The 12 channel digital audio amp is connected to the speakers throughout the home with volume controls in individual rooms. The sonos connect amps are connected to the zone inputs on the amplifier.
