The DME24N digital mixing engines employ Yamaha's original DSP6 and DSP7 signal-processing LSIs for extraordinary audio processing power and quality. The DME64N offers processing power that is on par with Yamaha's DM1000 digital mixing console. In either case you get a remarkable amount of processing capability that allows complex systems to be built around a single DME unit and fine tuned for optimum performance in concert halls, multi-purpose halls, event spaces, institutions, and a wide range of other applications. Plenty of DSP power also means that advanced configurations that previously required multiple hardware units can now run comfortably on just one DME64N. All of this translates into significant time, energy and cost savings for the design, installation and operation of DME-based systems. The DME64N has four rear-panel expansion slots that accommodate Mini-YGDAI I/O cards. Each slot supports up to 8 analog inputs or outputs when fitted with precision A/D or D/A cards or up to 16 channels of digital I/O in AES/EBU, ADAT or TASCAM format. With its four expansion slots the DME64N can support up to 64 channels of I/O. For even larger systems up to eight DME64N units can be cascaded to provided a massive 512 digital inputs and 512 digital outputs or 128 analog inputs and 128 analog outputs. The analog inputs and outputs feature precision 24-bit, 96kHz A/D and D/A converters that deliver top class audio performance.
