DSP power that rivals the Yamaha DM1000 digital mixer and expands the boundaries of configuration design

The DME64N and DME24N offer such powerful performance complements of Yamaha’s proprietary DSP7 and DSP6 LSIs, which were designed exclusively for audio processing. The DME64N features processing power to rival Yamahas highly acclaimed DM1000 digital mixer, while the DME24N offers about half that.

This awesome DSP power offers two big advantages. First, it gives a single DSP box enough muscle to build larger, more complex DSP configurations, giving audio designers a free hand in fine-tuning audio signals for systems in concert halls and a wide range of other venues. And second, it makes configuration design easier than ever – because configurations that once required multiple DSP boxes can now be run with one DME64N or DME24N. Which means big time and energy savings in both design and actual installation, making these Yamaha DMEs affordable solutions as well.

Sound-focused circuitry design with 24 bit/96kHz processing support for the ultimate in sound quality

Highly recommended by leading professionals for live performances and studio recording, Yamaha digital mixing engines inherit our cutting-edge audio technologies in mixing console development – including power supply unit placement and proper grounding. And the results speak for themselves. No wonder the DME64N and DME24N can deliver peerless fidelity in reproducing any original sound – to the point of rivalling a large mixing console. The DME24N, for instance, is redefining the boundaries of audio fidelity at 24bit/ 96KHz operation with newly developed head amplifiers onboard. Just one more reason the best sound in the world comes from Yamaha.
Note: Configurations that can be created at 96kHz operation will be half the size of those that can be
created at 48kHz operation.

Exceptional I/O flexibility and expandability. Cascade up to 8 DME64Ns for 512 input/512 output capability

The DME64N features 4 mini–YGDAI slots on its rear panel for optional I/O cards. The DME24N features one slot. These slots support analog inputs and outputs when using high–precision A/D and D/A cards with up to 8 I/Os, as well as AES/EBU–, ADAT–, and TASCAM–compliant digital I/O cards with 16 I/Os. Thanks to these YGDAI slots, the DME64N and DME24N offer additional support for I/Os over a wide range of audio formats.

As a result, the DME64N can support up to 64 input and 64 output channels with 4 MY card slots. The DME24N accommodates up to 24 x 24 – with 8 analog inputs and 8 analog outputs onboard, plus one MY card slot. In addition, up to 8 DME64N devices can be cascaded to support large–scale applications, providing a maximum of 512 inputs/512 outputs with digital I/O MY cards and 128 inputs/128 outputs with analog I/O MY-cards.

DME24N rear panel features 8 analog input and 8 analog output terminals

The DME24N’s rear panel features 8 mic/line analog inputs and 8 output Euroblock terminals. Each terminal offers built-in high-precision 24 bit/96 kHz A/D– and D/A–converters, which in practice, not only makes installation fast and easy, but translates into some of the best cost performance in the business.

MY16-C mini-YGDAI I/O card ensures CobraNet™ compatibility

With the addition of the new 16-I/O MY16-C card that supports the CobraNet™ advanced digital audio network, Yamaha’s mini-YGDAI card portfolio now offers a broader range of digital format I/O cards. These cards enable network construction with other CobraNet™-compliant products – including the NHB32C network hub and bridge and the ACU16C amp control unit. The DME64N can support up to 2 MY 16-C cards. The DME24N, one.

Control Network via Ethernet

Up to 16 DME64N, DME24N and ICP1 intelligent control panel units can be connected via their RJ45 connectors to form an Ethernet network. Making use of existing 100base-T CAT 5 cables and other Ethernet infrastructure components enables quick, easy, cost-effective system construction.

Comprehensive GPI, RS-232C, USB and MIDI control signal support

The DME64N and DME24N offer a wide range of control interfaces for use with different units. The DME64N has 16 in and 16 out GPI ports to link with installed sound systems and other equipment. The DME24N has 8 I/O. What’s more, both include RS232C / RS422 serial ports for interfacing with remote control units and PCs, USB ports for popular PC interfaces and MIDI IN/OUT interfaces for synchronization with electronic musical instruments, sequencers and stage lighting controllers.

Jumbo LCD display with extensive front panel controls

Both DME64N and DME24N offer outstanding ease of operation thanks to their large, easy-to-read backlit LCD displays and comprehensive clusters of front panel controls – LED status indicators, jog wheel and SCENE, Home and Utility keys. A monitoring headphone jack with phone level control is standard. The DME24N also provides SIGNAL and PEAK LED indicators on the front panel for 8 inputs and outputs.

Scene and function names in 5 languages

The DME64N, DME24N and ICP1 intelligent control panel can display names for scenes and function keys in 5 languages – Japanese, English, French, German and Spanish. And all 3 units feature a user-friendly interface for trouble-free operation regardless of level of skill or experience.

With the advent of digital audio consoles and recording devices, the need often arises for a digital output to be sent to multiple digital inputs. But digital signals cannot be split as simply as analog audio signals.

Trouble-free transmission of digital audio requires strict adherence to standards for input and output impedances as well as wiring. If the standards are not met the robustness of the system can diminish causing noise, dropouts, or complete loss of signal.

As the sampling rate increases, so does the possibility of failures. Changing the input impedance by wiring two or more inputs across one output simply does not work.

There are many digital audio distribution amplifiers on the market. They can do many things such as reclocking, reshaping, matrixing, format conversion, etc. But when the need is only for splitting, especially multiple channels, these other devices are prohibitively expensive, bulky, and difficult to set up.

The Model 148 was developed specifically for those applications in which the requirement is to feed the same digital audio signal to multiple inputs. It is clean, stable, and extremely cost effective.

Through the use of 15-pin D sub connectors the 1/2 rack unit can split 8 channels (4 pairs) of digital audio into 32 channels (16 pair). The D-subs follow the standard used on the Model 1788 remote controlled mic preamplifier. See the back panel illustration above for the wiring diagram.
The Model 148 can be mounted in a rack singly or in pairs with the Aphex Model 44-008SA Rack Kit.
An Operational Bonus
The Model 148 incorporates 20dB of saturated gain to square up the input signal. In many cases it can be used as a booster amplifier to restore a signal to full drive at the end of longer runs.

The Model 148 can be internally configured for either 110 ohms balanced or 75 ohms unbalanced operation.

The XTA DS800 Mic / Line Distribution System is a high quality active distribution /splitter unit containing eight channels of processing in 2U of rack space. Each channel features one actively balanced input and a total of four outputs, two of which are individually actively balanced and normally connected to Front Of House and Stage Monitor consoles. The two remaining outputs are transformer isolated and located on the front panel of the unit. These are typically used as broadcasting or recording feeds. A maximum of 50dB gain is available via the five position Gain switch. This allows sufficient gain to be applied to low level signals, such as dynamic microphones, to avoid the poor noise performance often associated with active mic splitters. Phantom power (48VDC) is provided, and is switchable to each input by selecting ‘Phantom Power’ on the front panel. The DS800 is designed to reduce system grounding problems; please refer to the ‘System Grounding’ section further on in this manual for more information.
