The DME8i, DME8o and DME4io are the latest additions to Yamaha's innovative DME series of digital mixing engines that allow complex audio systems to be designed and created via software running on a computer. The "C series" models (DME8i-C, DME8o-C and DME4io-C) feature a CobraNet™ network interface for advanced networking flexibility in complex installations, while the "ES series" models (DME8i-ES, DME8o-ES and DME4io-ES) come equipped with EtherSound™ networking capability that provides easy setup for remote placement of analog input and output devices in temporary sound reinforcement systems. Both types offer greater freedom for system design while reducing cabling costs, and overall system redundancy and reliability can be enhanced through distributed placement of analog I/O and signal processing.
