DME24N, DME64N Digital Mixing Engine

พารามิเตอร์ภายในของ DME64N และ DME24N สามารถทำการควบคุมได้โดยตรงจากดิจิตอล มิกซิงคอนโซล PM5D เพื่อการปฏิบัติการที่มีประสิทธิภาพ และราบรื่น คุณสมบัตินี้มีประโยชน์มากเมื่อ DME อยู่ไกลจากตำแหน่งการฟัง ทำให้สามารถปรับพารามิเตอร์ได้โดยไม่ต้องลุกไปจากเมนคอนโซลเลย

DME64N, DME24N และแผงควบคุมระบบอัจฉริยะ ICP1 สามารถแสดงชื่อของซีน และฟังค์ชันได้ 5 ภาษา คือ อังกฤษ, ญี่ปุ่น, ฝรั่งเศส, เยอรมัน และสเปน โดยทั้งสามรุ่นมีอินเตอร์เฟสที่ใช้ง่ายเพื่อการปฏิบัติการอย่างไม่มีปัญหา ไม่ว่าจะเป็นผู้ใช้ระดับไหนก็ตาม

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.

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.

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.

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.

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.

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.

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.

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.

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.
