Yamaha CIS MRX7-D Open Architecture DSP Processor Product Details Central Management of Multiple Sound Systems from a Single Processor Sound system requirements for corporate conference rooms, educational facilities, shopping malls, and a variety of other environments are becoming increasingly large and complex. The MRX7-D offers outstanding control efficiency and flexibility for a broad spectrum of audio installations. Because the MRX7-D's design architecture is freely configurable, it allows an audio engineer to create a unique solution for the customer which can incorporate many unique processing components and maximize the use of available DSP. Having built in Dante connectivity, it also allows audio systems to take advantage of the many other Dante enable products on the market including Yamaha's wide range of Digital Mixers. Flexible & Expandable The MRX7-D takes full advantage of the globally adopted Dante networking technology. Dante is a true digital network that increases the flexibility and expandability of an audio system while helping to reduce the cost. It can handle and distribute high numbers of audio channels over long distances to many devices on the network simultaneously. With so many Dante enable devices available, such as microphones, processors, digital mixers and amplifiers, it is the ideal choice for medium to large scale system designs. An Intuitive Graphical Interface for Sound System Design There are two design software applications available for use with the MTX/MRX Series.
