DME24N, DME64N Digital Mixing Engine

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 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.

Speaker processing can be essential for achieving maximum performance from professional speaker systems as well as for delivering optimum sound quality throughout the listening area. DME processors include everything needed for precision speaker tuning and room matching: versatile crossover processors with APF (All Pass Filter for phase control), horn EQ, delay, limiter functions and more.

The Room Combiner component adds multiple audio signals to "virtually" combine the acoustic spaces of multiple rooms. Mono and stereo components that combine 4, 8, 12, or 16 rooms are available. This component provides an effective solution for situations in which several rooms or areas can be physically partitioned or combined to handle different types of events or numbers of participants. Sources and outputs can easily be switched as required, and the processing for multiple areas can be handled by a single DME unit.

This function automatically adjusts gain to maintain a consistent level even if the volume of a speaker's voice varies, for example. An indispensable function for meeting rooms and conferences.

The Auto Mixer II component 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.

The Program Ducker component features significantly longer attack and release times. Mono and stereo types can be flexibly configured to accommodate a wide range of applications. The Program Ducker offers all the versatility required for installations ranging from banquet halls to theme parks, while additionally providing camera tally link capability for broadcasting - a field in which the DME series is finding increasing acceptance.The Program Ducker can be triggered from an oscillator. This makes it possible to use the output of a single oscillator to simultaneously trigger multiple channels for 5.1 surround, for example.

The 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.

Yamaha SPX effects are recognized as being some of the best and most "musical" in the industry. In the DME processing engines you have full-featured SPX multi-effect processors that are on a par with those provided in top-line Yamaha production and live sound consoles.

As their names imply the Wav File Player component plays specified Wav audio files, and the Event Scheduler can be used to trigger it at predefined times and repeating cycles. This could be used to play opening and closing themes for a retail outlet or mall, for example. Event Scheduler triggering is not limited to Wav File Player operation, however, and it could be used to schedule a GPI output that could start an external CD player or other device, for example. Programming the scheduler is easy, and can be done by the end user simple via wall-mounted remote control units or other remote controllers. Playback level and on/off switching can also be accomplished via the same type of controller.

Caution: The hardware specification for DME Firmware V3.5x or earlier differs from the one for Firmware V3.8x or later. Therefore firmware V3.5x or earlier cannot be upgraded to V3.81 or later (including V4.0). If you need to upgrade your DME from V3.54 or earlier to V3.81 or later (including V4.0), please contact your Yamaha dealer.

New Component of DME V4.0

In a teleconference, sound is exchanged in both directions through communication lines. When the voice of the person speaking in room A is transferred to room B through communication lines and reproduced by a loudspeaker, that voice can be heard in room B. However the microphone in room B also picks up the voice of the person speaking in room A and sends that voice back to room A. Because of this, in room A, the voice of the person speaking is reproduced by the loudspeaker as an echo. This is referred to as acoustic echo. In addition to hindering conversation, it can cause feedback. To have a smooth conference, it is necessary to reliably suppress acoustic echo.

"With V4.0, Scenes now have a partial recall capability. So Scenes can be created that only recall one or more components

This function helps to reduce the time needed to create flexible control setups (MIDI / GPI / Remote Control Setup List) on multiple Scenes. If a Scene needs different MIDI or User Defined settings for example, then a new Configuration must be made. In V3.x, you need to duplicate the complete setup manually even if you want to change only a couple of parameters compared to the previous Configuration. Now there is a short-cut to replicate the configuration.
