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.
ADAT (Alesis Digital Audio Tape) A digital audio connection format used by ADAT compliant digital audio devices. Eight
channels of digital audio can be carried by a single optical “Tos-Link” cable.
AES/EBU (Audio Engineering Society/
European Broadcasting Union) A digital audio format jointly devised by the AES and EBU. Used primarily for digital audio
transfer between professional equipment. Two channels of digital audio can be handled via
a single connector (Left: odd number, Right: even number). Standard XLR connectors are
generally used for this type of connection.
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.
CobraNet An audio networking system developed by Peak Audio (a division of Cirrus Logic, Inc.) that
allows real-time transmission and reception of multiple channels of uncompressed digital
audio signals via a Fast Ethernet (100 megabits/sec.) network.
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.
Ethersound An audio networking system developed by Digigram Corporation.
It transmits uncompressed digital audio signals via Ethernet.
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.
