Like the DME32, the DME-N is a processor that can be assembled into a variety of audio systems including installation systems, sub-mixing, speaker system controllers, matrix/routing, or multi-effect processing (V1.1 and later), using the included DME Designer application software for Windows. The letter "-N" at the end of the model name stands for Network; these units can be controlled via a CAT5 cable.
The greatest difference is in the number of inputs and outputs. The DME24N has eight channels of internal AD/DA and one MY slot, allowing a maximum of 24-in/24-out processing. The DME64N has no internal AD/DA but provides four MY slots, allowing a maximum of 64-in/64-out processing. The DME64N contains DSP chips that provide approximately twice as much performance as the DME24N. The GPI interface is 8-in/8-out for the DME24N, and 16-in/16-out for the DME64N. In addition, the DME64N has a dedicated cascade connector.

When operating at fs=48 kHz: DME24N: 24IN24OUT (Internal AD/DA 8ch + Slot 16ch) DME64N: 96IN96OUT (Slot 16ch x 4 + Cascade 32ch) |
| When operating at fs=96 kHz: DME24N: 16IN16OUT (Internal AD/DA 8ch + Slot 8ch) DME64N: 64IN64OUT (Slot 8ch x 4 + Cascade 32ch) |
* When operating at fs=96 kHz, the slots will function as eight-channel in/out interfaces.
64-channel (24-channel for the DME24N) input/output is possible when optional Mini-YGDAI cards are inserted in the slots. The DME24 contains eight channels of built-in AD/DA, so eight channels of input/output are possible even without installing an option card. When running at fs=96 kHz, the number of input/output channels provided by a slot reduces to eight as mentioned in the preceding section.
Because the DSP hardware structure and the structure of the various components differs, a simple comparison (at the resource level) is not possible, but the DSP performance (excepting SPX type effects) can be compared as follows:
| DME24N : 128% of the DME32 |
| DME64N : 256% of the DME32 |
Since Ethernet jacks are provided, you can connect the DME-N to a LAN and control it from a PC. Also, the concepts of "zones" and "areas" have been added, allowing centralized management of an entire system of multiple DME-N units constructed on the network using the "DME Designer" software.
The user defined button titles can be shown in five languages; English, French, German, Spanish, and Japanese. However, all of the conventional setting menus etc. are in English.
When the MY16-C is used, a fixed latency is added each time the signal passes through the network. This added latency will be either 1.33ms/2.67ms/5.33ms depending on the mode, and can be specified by a DIP switch on the card.
This is because at the time of compiling, optimization is applied to each component to minimize the amount of delay.
One in the DME24N, and two in the DME64N.
Yes. There are two ways this can be done:
1) If you have previously downloaded the DME Designer project file to the DME file storage area (11Mb internal memory inside the DME-N), you can then upload this and any other files from the DME file storage area later.
2) If you have the same project file on the PC with which you have sent the setting data to DME, you can then upload any changes.
Choose the “Designer <- DME option” in the Synchronisation window.
The gain is adjustable in 1 dB steps over a range of -60dB - +10dB.
Yes. Since signals of differing sampling rates cannot coexist, and since the ACU16-C and NHB32-C will operate only at 48 kHz, the system must be operated at 48 kHz.
This function plays back WAV format audio files (filename extension .wav) that can be recorded on a personal computer.
You can listen to the slot input, slot output, cascade output, or cascade input. However, you'll need to select the monitoring point in the LCD menu. Also, while an arbitrary monitoring point cannot be selected from the DME-N itself, you can specify it from DME Manager.
No, it does not have a master setting; phantom power is specified individually for each channel.
No.
Yes. With the main screen displayed, simultaneously press the [HOME] button and the [ENTER] button to activate the Panel Lock function. To defeat it, press and hold the [CANCEL] button for at least two seconds.
This allows centralized control of multiple DME-N units, and since controllers such as the ICP1 can be used with such a system, it is possible to create systems with excellent flexibility. Since networking uses widely-available CAT-5 cables and switching hubs, installation is easy and cost-effective, and the system is easily maintainable.
An "area" is the space corresponding to the entire system; an area consists of multiple "zones." The acoustical settings of multiple zones can be controlled independently, and you can also control the entire system (area) as a whole.
In addition to the DME-N itself, an ICP1 or PC (DME Designer) can be connected. A switching hub is required in order to connect multiple devices.
A total of up to sixteen DME24N/DME64N/ICP1 units can be connected in a single zone.
No, this is not possible. Connect a single DME Designer to the DME-N unit that will be the master unit.
Yes, you can.
You will need the "DME-N Network (Ethernet-MIDI) Driver" in order to connect the DME-N to a network. This is supported in V1.01 and later.
If the DME-N's Ethernet cabling is to share the cabling of an existing LAN, zone network addresses must be separated so that devices with the same zone number are associated with the same switching hub.
Each zone contains one DME-N unit that is the "zone master," and the zone master will control other DME-N units within that zone. A computer that manages the entire area would be connected to the zone master.
The IP address must be specified individually for each DME-N and ICP1.
You cannot set the IP address from DME Designer. The IP address can be set only on the unit itself.
Yes. We do not specify recommended models of switching hub as in the case when using CobraNet. You can use commercially available 10/100 Mbps switching hubs.
However, the transmission distance or speed may be affected by the switching hub you use.
It is possible to do this using only a single switching hub, but since the performance may be degraded by large amounts of CobraNet audio data, we recommend that you keep the networks separate.
The "ICP1 (Intelligent Control Panel)" is a dedicated controller for the DME-N. It can be connected via a network hub (or via cross-cable) to the DME-N and LAN in order to control the DME-N.
You can recall scenes, and edit component parameters using six assignable function keys x four banks (total of 24) and a rotary encoder.
The ICP1 must be connected to the included adaptor box. Connect a network cable (CAT5) and power supply cable to the adaptor box. Within the adaptor box, the network signal and power supply are redistributed onto the CAT5 cable, and connected to the ICP1.
As for a 100 Mbps (100BASE-TX) LAN, the maximum length is 100 m (theoretical value). However, the cable may not pass through a switching hub on the way.
As on the DME-N itself, five display languages are provided; English, French, German, Spanish, and Japanese.
Yes, they can if the DME-N units are in the same zone.
No, they cannot.
The minimum unit by which a parameter's value changes is fixed for each parameter. The way in which dial rotation speed affects the change is also fixed. These cannot be specified by the user.
The DME24N provides 8IN/8OUT, and the DME64N provides 16IN/16OUT. By using GPI controllers you can control the DME-N's internal parameters or view the parameter status via external lamps.
If the CD player has GPI functionality, it can be controlled.
Yamaha sells three models; the CP4SF (4 faders, 4 switches), the CP1SF (one fader, one switch), and CP4SW (4 switches). Each switch contains an LED. The included frame plate can be used to install these in a conventional electrical outlet box.
Yes. Connect the switches in parallel to the GPI (+) and (-) pins. When you press one of the connected switches (for example), the specified scene will be recalled.
For example if you want to set Delay to 40 msec when you turn a switch on, you would set the maximum value of GPI IN to 40 msec and set the minimum value to 0 msec. Then set Terminal to Toggle Low->H to allow this type of operation.
CPEV cable (city pair polyethylene insulated vinyl sheathed cable) with 0.65 mm or greater diameter copper conductor and a length up to 100 meters can be used.
You can control component parameters and scenes by transmitting control change, parameter change, or program change messages.
Yes.
In DME Designer, you can specify the values by using the mouse to graphically adjust the bar. However you cannot directly input numerical values.
Windows 2000 and Windows XP.
The unit needs to be connected only while transferring data or while editing parameters from DME Designer; it is not necessary that the unit remain connected to the PC at other times.
The time required will depend on the number of scenes and on the configuration state of the DME-N.
Slightly less than one minute is required in order to send the DME24N a configuration containing no components and in which IN is connected directly to OUT.
When adding components to existing data, only the data for the added components is transmitted, so the transmission time will be shorter.
This icon specifies the ports that the "YAMAHA MIDI Driver" will use. From the ports you select here, select the port that will be used for communication between DME-N and DME Designer. You cannot delete this icon. However, you can minimize it into System Tray by right-clicking the icon and selecting 'Minimize'.
There is no difference. You will need either the USB-MIDI driver or the Ethernet-MIDI driver, respectively.
You will need "DME-N Network Driver" which is supported in V1.01.
Yes. In "Security" menu, turn "Startup User Control" ON.
This can be done by using the security functionality provided by DME Designer.
The "number %" shown for each component indicates the proportion of DSP resources used.
This is because the DSP Resource Meter is just a general guideline; only by actually compiling the data can it be determined whether the components can be placed. Compilation uses a new algorithm that applies highly efficient optimization. This means that in some cases, it may be possible to place components even if the meter exceeds 100%.
Yes. You can specify the width, the type of line (line/dot), and whether it is hidden or visible. You can also turn on "Snap to Grid" so that objects are placed neatly.
Yes. You can also input "-∞" by typing "-I" (indicating Infinity).
You can control them via GPI or RS232-C.
Such components are not provided.
Yes. You can draw a parallel connection not only from the output jacks of a component, but also directly from a connected line.
This is not possible. In order to mix signals, you must route them through a Mixer or similar component.
You are free to put a name to the label displayed at the top of the component.
The DME-N itself provides a spectrum analyzer linked with the monitoring functionality.
You can use the parameter link function to link them.
You can use the parameter link function to link parameters across multiple components.
You can use the probe monitor function to audition the signal at a desired point.
Yes.
DME Manager and DME Designer are not compatible; they cannot load each other's files.
The DSP resource meter is calculated based on the number of arithmetic steps in the DSP microprogram. However, parameters that affect whether a component can or cannot be placed on the DSP are limited not only by this number of calculation steps but also by the number of inputs and outputs between the DSP chips. If you place the Matrix64x64 component, no further components can be placed due to this limitation on the internal DSP inputs and outputs.
Up to 999 scenes can be stored, but since the configuration is also managed as part of the scene, the maximum number of scene memories will decrease depending on the size of the configuration data.
Scene memories are recalled simultaneously for all DME-N units in the same zone. They cannot be recalled individually for each unit.
The DME-N can hold multiple configurations, and these can be changed for each scene memory. In this case, the sound will be interrupted.
The time it takes for a recall will depend on the number of parameters and on the state of the configuration.
If the scene change involves only simple parameter changes and does not change the configuration, the change will occur in less than a second. If the change involves a configuration change, it may take several seconds for the recall to occur, depending on the configuration.
Yes.
Up to eight DME64N units can be cascaded. Since the DME24N does not have a cascade connector, it cannot be cascaded.
Cascading allows expansion up to a total of 512 inputs and outputs, letting you construct very large systems.
There are 32 cascade buses.
When DME64N units are cascaded together, I/O signals for 32 buses travel on one cable, for a total of 64 buses. When connected to a mixer such as the PM5D, signals for 32 uni-directional buses travel on one cable.
Viewed from the zone master DME64N which is at the highest point in the cascade, transmission will be interrupted for audio signals from the DME64N unit whose cable was broken and from units that precede it; however DME64N units from the zone master until the DME64N that follows the broken cable will continue functioning normally.
You can transfer up to 32 channels of audio signals, and control DME-N component parameters that are supported by the PM5D's DME Control function.
No. Component library functionality belongs to DME Designer.
A cascade connection of "PM5D -> DME64N -> DME64N" is possible. However, only the first DME64N can be remotely controlled from the PM5D.
| 1) PM5D -> DME64N <-> DME64N -> Select whether the buses to be cascaded will be used for the PM5D or for the DME-N. DME-N control will be possible for the components of all DME-N units in the same zone. |
| 2) PM5D -> PM5D -> DME64N -> DME-N control will be possible for the components of all DME-N units in the same zone. However, DME-control is not possible from the first PM5D which is not directly connected to the DME-N. |
You can use CAxxx cascade cables for the DM2000 or 02R96; available in five lengths as the CA003, CA010, CA050, CA100, and CA200.
| When cascading DME64N units together: |
| At a sampling rate of 44.1kHz/48kHz: 100m At a sampling rate of 88.2kHz/96kHz: 30m |
| When cascading with the PM5D: |
| At a sampling rate of 44.1kHz/48kHz: 200m At a sampling rate of 88.2kHz/96kHz: 100m |
Since control between DME-N units occurs only via Ethernet, all DME-N units must be Ethernet-connected.
It takes approximately 1 minute 30 seconds to update the program area, and approximately three minutes to update all components.
The DME-N/ICP1 can be updated from a PC via USB or Ethernet (supported in V1.01 or later). Start up DME Designer, specify the menu that you want to update, and select the target DME-N. It is not necessary to initialize the memory, and the internal scene memories are not deleted by the update procedure.
