The DME4io-ES is a programmable digital audio processing engine interfacing with both the analog audio and the EtherSoundTM audio. EtherSoundTM audio allows connecting by using the standard CAT5 LAN cable to distribute the audio. The star and daisy-chain connection between units provide the flexible and expandable connection in a local area such as in a recording studio or in a broadcast. The DME4io-ES features 4 analog audio inputs, 4 analog audio outputs, and the EtherSoundTM consists of 16 channel audio input/output. The DME Satellite series provides the expandable audio distribution system allowing the remote operation via RS232C, GPI or Ethernet. The DME Satellite is suitable for the wide range of installation with the expandable capability and the reasonable cost.


  • Interfacing to 4 analog audio inputs, 4 analog audiooutputs, and one EtherSoundTM (16 in/out). EtherSoundTM carries 64in/64outchannel signal in a CAT5 LAN cable with the extremely low latency 120microseconds (@48kHz).
  • 1U rack mount size with the powerful processingcapability.
  • DME satellite series provides the audio distributionflexibly meet to large to small scale installation.
  • The higher model DME64N/DME24N works as the core forthe large system.
  • Standalone 4in/4out system with the high performanceof DSP processing is capable, additionally flexibly expandable to the12in/4out or 4in/12out system with the DME8i-ES or the DME8o-ES.
  • High performance Yamaha DSP chip is mounted, and 80%of the processing capability of the DME24 is realized in 1U unit. (excludingEffects function on the DME24N)
  • The DSP chip provides versatile component includingEQ, Crossover, Delay and etc. These components are realized by programmingwith the Yamaha DME designer application software running on the Windows PC.
  • High quality sound with 24bit/96kHz, and the acclaimedperformance of mic-preamplifier, AD/DA and grounding technology.
  • The 9 pin serial communication terminal is for theAMXTM and CrestronTM, and the control the AD8HR (Yamaha A/D converter with thevariable head-amplifier gain)
  • GPI terminal for the switch and fader control.
  • Ethernet connector and USB port for communication withthe PC.
  • Optional LCD panel for the Ethernet connection, and the optionalswitch/fader panel for GPI connection.

The Digital Mixing Engine shall incorporate DSP engine, 4 analog audio inputs and 4 outputs, EtherSoundTM input/output, and communication capability in 1U rack unit. The total system shall meet the following performance criteria: 4 analog inputs configured by the Euroblock on the rear shall include head-amplifier with the gain covering from microphone to line level (-60dB to +10dB). 4 analog outputs configured by the Euroblock on the rear shall have +24dBm as max output level. EtherSoundTM configured by the RJ-45 connector on the rear shall handle 16 channel input/output out of 64 channel on the network. Internal DSP function shall be programmed by using the DME designer (software) running on the Windows. The latest version of software shall be freely downloadable. Delay, Dynamics, Filter, EQ, Pan, Auto Mixer, Matrix Mixer, Wav File player, router and etc shall be created. The Ethernet connector with RJ-45 shall be for the communication to the PC or the optional intelligent control panel. And one USB port shall be on the front for PC communication. 8 in 4 out GPI configured by the mini-Euroblock on the rear shall allow connect the GPI faders, switches, and lamps for status monitoring. The serial 9 pin terminal on the rear for RS232C/RS422 shall be used for AMXTM or CrestronTM, either for control the gain of Yamaha AD8HR (1U AD converter with Head-amplifier).
