DME24N, DME64N

The DME64N and DME24N 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 a par with Yamaha's DM1000 Digital Mixing Console, and the smaller DME24N has about half that processing capability while offering built-in analog I/O for simple, more compact systems. 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 or DME24N. All of this translates into significant time, energy, and cost savings for the design, installation, and operation of DME-based systems.

It's no secret that Yamaha digital mixing consoles are favored by leading professionals for live sound and studio recording applications. Yamaha DME mixing engines benefit from the same cutting-edge audio technology and attention to details that make a real difference in sound and performance. Both the DME64N and DME24N deliver faultless precision and reproduction fidelity with optimally-tuned 24-bit, 96-kHz digital processing, and the DME24N also features high-performance analog head amplifiers that equal the sound and quality of those found in top-line mixing consoles.

Note: Configurations created for 48-kHz operation will require half the processing power of configurations created for 96-kHz operation.

The DME64N has four rear-panel expansion slots that accommodate Mini-YGDAI I/O cards, and the DME24N has one expansion slot. 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 it's four expansion slots the DME64N can support up to 64 channels of I/O, while the DME24N has a single slot plus 8 channels of built-in analog I/O for a total of 24 channels. 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.

Selected DME64N and DME24N parameters can be directly controlled from the PM5D Digital Mixing Console for seamless, efficient operation. This capability is particularly useful in situations where the DME unit is located away from the optimum listening position, allowing parameters to be adjusted without having to leave the main console position.

The DME24N provides eight built-in analog inputs and outputs via Euroblock terminals on the rear panel. The analog inputs and outputs feature precision 24-bit, 96-kHz A/D and D/A converters that deliver top class audio performance.

Use the DME64N or DME24N in an advanced CobraNet" digital audio network by simply plugging an MY16-CII CobraNet™ card into an expansion slot. This makes the DME unit compatible with other CobraNet™ compliant products such as the NHB32-C network hub and bridge, and the ACU16-C amplifier control unit. The DME64N can supports up to two MY16-CII cards. The DME24N can accommodate a single MY16-CII card.

A network of up to 16 DME64N, DME24N and ICP1 Intelligent Control Panel units can be interconnected via their RJ45 connectors and 100Base-T CAT5 type Ethernet cables. Ethernet connection makes it possible to set up a control network quickly and easily, and with minimum cost.

Both the DME64N and DME24N offer a comprehensive selection of control interfaces for use with a wide variety of equipment. The DME64N has 16 GPI input and output terminals while the DME24N has eight to facilitate interfacing with other GPI-equipped devices. RS232C/RS422 ports allow direct connection to remote control units and computers, USB ports allow direct hookup with most modern computers, and MIDI terminals can be used for synchronization and control with musical instruments, sequencers, and lighting controllers.

Large, easy-to-read LCD display panels and a comprehensive selection of panel controls make the DME64N and DME24N easy to operate. The front panel even includes a headphone jack and level control for convenient monitoring. The DME24N additionally provides signal and peak LEDs for its eight analog inputs and outputs.

The DME64N and DME24N, as well as the ICP1 Intelligent Control Panel, can display scene and function names in 5 languages: English, Japanese, French, German, and Spanish. All three models offer a user-friendly interface for smooth operation regardless of the user's level of skill or experience.

The DME64N and DME24N Version 2 models include a new Feedback Suppressor component with selectable Speech and Music modes.

Version 1.2 and later include a Speaker Processor component that includes horn EQ, an all-pass filter for polarity control, 6-pand parametric EQ, and more.

After setting up an audio system it is possible to use the User Control function to create customized control interfaces that include only specified parameters.

The DME Designer allows centralized control of multiple DME-N, DME Satellite, and SP2060 units connected to a network. Devices used for similar or related functions — for example, a group of devices dedicated to speaker processing — can be organized into "Device Groups" and switched all at once via scenes. Total scene recall can also be applied to complete audio system "Zones" — for example the entire audio system for one hall in a complex — giving you a vast range of options for centralized and distributed control and management.

Multiple Zones in a large facility can be defined as an "Area", and the details of the Zones and Devices Groups it includes can be freely set up or modified as required via the DME Designer. Entire systems of this type can be easily saved and loaded in the form of DME Project Files.

The DME Designer is a total system design program, and the Zone window can be used to create comprehensive plans for audio systems that include digital mixers and other external equipment. Since version 1.2 the DME Designer can function as a launcher for Yamaha digital mixer and effect editor as well as amp monitor software, allowing extensive data storage and project management capability via project files.

As of DME version 1.2, DME configuration data can be stored in the DME unit itself. The system engineer can internally store the appropriate project files when the system is initially set up to facilitate subsequent maintenance.

An Auto Gain Control component that automatically compensates for variations in the level of a speaker's voice, and an Auto Mixer II component that provides an over-ride function and automatic output level control make it possible to create "intelligent" systems that provide automated control for applications that don't require the presence of an experienced operator.

Version 3 includes a Room Combiner component that greatly facilitates the combining and dividing of rooms in conference venues for example, as well as the control of zoning in undivided spaces at shopping centers or theme restaurants. Additional Router and Matrix component variations have also been provided for increasing further the capability and efficiency of system design.

The new Ambient Noise Compensator component can be used to measure ambient noise levels and automatically and dynamically adjust the program level for optimum balance and intelligibility. This function can be useful, for example, to optimize the level of announcements at shopping malls at which the ambient noise level may vary greatly depending on the time of day or day of the week.

The Audio Detector component generates GPI output based on whether or not an input audio signal is detected. This capability could be used, for example, to automatically pan a camera to the current speaker during a conference, control lighting, or perform other advanced functions. Conversely, it could be used to detect when an audio input has stopped and change scenes accordingly.

A simple but very useful stereo mixer available in 16-input and 24-input variations, both with dual auxiliary sends. This component can significantly enhance system design flexibility in a wide range of applications.

"All File" export and import capability makes it easy to transfer user modules, image files, and all other relevant DME data from computer to computer, and a "Device Information" display lists the status of all DME devices on a network. These are just two of many features that make setting up and maintaining a commercial audio system easier and more efficient than ever.

DME series processors are participants in the AMX Duet Partner Program, and offer full support for Dynamic Device Discovery. DME processors, with their extensive feature set and versatility, offer a familiar Duet programming and control environment for smooth integration with other Duet devices. Version 3 additionally allows AMX and DME Satellite devices to be connected via Ethernet for significantly improved cabling efficiency.

Yamaha is currently working with Crestron to implement full compatibility and easy programming with their touch-panel controllers as well.

This upgrade makes it possible to remotely control the gain of the high-performance microphone/line head amplifiers built into the DME24N, DME8i, and DME4io units via AD8HR protocol. This means that the DME head amplifiers can be remotely controlled via an expansion slot on the LS9 or a similar digital mixer or any other product with HA remote capability and a Dsub 9-pin REMOTE connector.

The DME Designer application provides full support for the DME Satellite ES types to be released concurrently with the start of the DME Version 3 download service, giving you a choice of audio network protocols to suit your specific application. Install the Yamaha MY16-CII CobraNet interface or Auvitran AVY16-ES EtherSound interface in a DME-N unit to allow remote connection to the corresponding type of DME Satellite I/O unit for flexible network system construction.

A preference has been added that allows easy daylight saving time compensation when using the Event Scheduler and Wav File Player components to provide automated chimes or announcements.

As of Version 3 the DME Designer application is compatible with the Windows Vista operating system (Business, Enterprise, and Ultimate).
