Installation Case
Tucked into the wooded hillsides of the Ozark Mountains near Branson, Missouri, Big Cedar Lodge is a popular destination with both holidaymakers and as a corporate meeting venue. The latter aspect has recently been enhanced by the addition of the new Grandview Conference Center, which is host to five Yamaha IMX644 rackmount digital mixers.
Installation Case
As well as excellence in professional audio Yamaha also, of course, enjoys a global reputation for the quality of its motorcycles and musical instruments. All three elements have come together at Red Point Café in Milan, a venue where motorcycle enthusiasts from across Italy can come together to discuss their passion in the presence of iconic Yamaha bikes, while enjoying high quality music and audio from, of course, Yamaha musical instruments and professional audio technology.
