12.1 Glossary of Terms and Abbreviations

A

Add-In
Product control software, such as HELIX
RCS, which works under the ELGAR
Library Manager Shell.

B

Bandwidth
In EQ, the width of a band comprising a
range of frequencies that will be boosted
or cut above and below a selected centre
frequency.

D

dB
Abbreviation for decibel.

E

ELGAR
The ELGAR Library Manager Shell is the
generic container of a number of Midas
and Klark Teknik products, known as
Add-Ins. It provides a single place to
store, load and edit Remote Control Add-
Ins, such as the Helix RCS.
EQ
Abbreviation for equalization, which is the
process of altering the levels of
frequencies that comprise a signal.
Equaliser
A device that boosts or cuts the volume
of specific frequencies in a signal.
Ethernet
The most common method of networking
computers in a local area network (LAN).
A physical standard that uses several
wires twisted in pairs to allow computer-
to-computer communication. Also, the
basic communications protocols over such
wires – the same protocols are also used
for Wireless Ethernet.

F

FastNav®
An area of the screen – or a screen itself
in the case of the HELIX EQ units – that
makes it easier to work with multiple
units.

H

HELIX
All of the new Ethernet units from Klark
Teknik, which includes the HELIX EQ
system – DN9340E Dual EQ unit,
DN9344E Quad EQ unit and DN9331
RAPIDE Graphic Controller – as well as
the HELIX DN9848E System Controller.
The older version of HELIX comprised the
DN9340 master unit and DN9344 slave.
HELIX DN9848E RCS
Software that allows remote
programming and control of HELIX
DN9848E units via a PC.
HPF
Abbreviation for high pass filter.

I

IP address
Unique identifier for networked computer
or device. An IP address comprises a
32-bit numeric address written as four
numbers separated by periods, with each

L

LAN
Abbreviation for local area network.
Short-distance network for linking a
group of computers together within a
building.
LPF
Abbreviation for low pass filter.

P

PC
Abbreviation for personal computer.
PEQ
Abbreviation for parametric equalisation
or parametric EQ. Equalisation where all
of the parameters of equalization can be
adjusted to any amount, such as centre
frequency, the amount of boost or cut in
gain, and the bandwidth or Q.

Q

Q
The sharpness of the peak response in an
equalization circuit. Related to bandwidth
– the larger the bandwidth, the lower the
Q.
