Terms Explanations
100Base-TX A physical specification for a 100 Mbps Ethernet network connection using 2-conductor
Category 5 UTP cable included in the IEEE 802.3u standard. Maximum data transfer
distance is 100 meters.
10Base-T A physical specification for a 10 Mbps Ethernet network connection using 2-conductor
Category 3 UTP cable included in the IEEE 802.3i standard. Maximum data transfer
distance is 100 meters.
BNC (Bayonet Nut Connector,
or Bayonet Neill Concelman)
A type of connector used for high-frequency connections using thin-core coaxial cable.
An internal spring ensures a solid connection.
Cascade A means of connecting Yamaha digital audio equipment to allow transfer of audio, control,
and word clock signals. Yamaha cascade connections employ half-pitch 68-pin D-Sub
connectors.
Category 3 Electrical specifications for one type of UTP cable jointly developed by the TIA
(Telecommunications Industry Association) and EIA (Electronic Industry Alliance). Several
categories are specified according to electrical characteristics, with higher category
numbers denoting higher quality cable. Category 3 cable can be used for transmission
speeds up to 10 MHz.
Category 5 Electrical specifications for one type of UTP cable jointly developed by the TIA
(Telecommunications Industry Association) and EIA (Electronic Industry Alliance). Several
categories are specified according to electrical characteristics, with higher category
numbers denoting higher quality cable. Category 5 cable can be used for transmission
speeds up to 100 MHz.
Component The basic modules that are combined to create DME64N/24N audio systems. In addition to
complete audio processors such as mixers, compressors, effects, crossovers, etc., a range
of smaller functions such as faders, switches, pan controls, and meters are also available.
Components can also be customized.
Configuration A set of components and connections that make up an audio system in the DME64N/24N.
D-Sub Another common form of connector that gets its name from the “D” shape of the connector.
This type of connector can be securely attached using screws. Individual “pins” are used to
connect each of the cable’s conductors. D-Sub connectors come in 9-pin, 15-pin, 25-pin,
37-pin, and other sizes.
DSP (Digital Signal processor) A semiconductor chip (LSI), or device containing one or more such chips, developed
specifically to process large volumes of data in real time. Ideal for processing digital audio.
Ethernet A network protocol jointly developed by the Xerox, DEC, and Intel corporations, and
codified in the IEEE 802.3 industry standard. Transfer speeds have increased to 100 Mbps,
1000 Mbps, and 10 Gbps from the initial 10 Mbps, while maintaining network compatibility.
Euroblock A connector system consisting of plug and socket components that allows easy, solder-less
wiring for a range of installations and devices. Simply insert the wire into the plug slot,
tighten the screw, and plug into the socket to complete the connection.
GPI (General Purpose Interface) A general-purpose control interface that can be used to allow control of the DME64N/24N
via external devices and custom-made controllers. Connections are made via a Euroblock
connector. The optional CP4SW, CP1SF, and CP4SF control panels also connect via GPI.
Initial Settings The initial values and settings of all editable parameters that will be in effect when a device
is powered on for the first time after it is shipped from the factory. Also known as “default
settings” or “initial factory settings.”
MAC (Media Access Control) Address The MAC address is also known as the Ethernet address, and is an independent address
assigned to all Ethernet devices worldwide. No two devices can have the same address.
MIDI (Musical Instrument Digital Interface) An international standard for data communication between electronic musical instruments
and audio devices.
Mini YGDAI (Yamaha General Digital Audio
Interface) card
A standard for I/O cards that can be installed to Yamaha audio products.
Phantom Power A power delivery system that allows power to be delivered to devices along with audio
signals via standard balanced audio cables. The term “phantom” is applied because the
system uses the audio conductors for power delivery without disrupting the audio signal
– the power is not “seen” by the audio signal.
Preset Parameter The parameter set of all components included in a configuration.
RJ-45 An 8-conductor modular connector used for Ethernet cable and ISDN telephone
connections. The appearance is similar to the RJ-11 connectors used for telephone lines,
but the connector is actually somewhat larger. “RJ” stands for “Registered Jack,” and is a
connector type included in the Bell System USOC (Universal Service Ordering Codes)
standards.
Router An equipment that relays data in network by selecting the most effective route.
