Abbreviation for ‘high pass filter’. A filter that removes lower frequencies
from a signal, leaving the higher frequencies unaffected.
Hum:
Undesirable low frequency tone present in a signal due to grounding
problems or proximity to a power source.
Hz:

per second.
I
I zone:
Area on the master bay that contains the operator-assignable
effects controls.
I/O:
Abbreviation for ‘input/output’.
ID:
Abbreviation for ‘identification’.
Ident:
Scale marking, or gradation, around a control knob to help indicate the

operating systems.
L
LCD select button:
LCD button in the input fast strips and VCA groups, used for
channel/group navigation and selection, and operator feedback.
LFE:
Abbreviation for ‘low frequency effects’. Typically, the ‘.1’ in ‘5.1 surround’ is
an LFE channel.
LFO:
1. Abbreviation for Low-Frequency Oscillation, an electronic signal which
is usually below 20 Hz and creates a rhythmic pulse or sweep. This pulse or
sweep is often used to modulate synthesizers, delay lines and other audio
equipment in order to create effects used in the production of electronic music.
2. Abbreviation for Low-Frequency Oscillator, the device itself which produces
low-frequency oscillation.
LS:
Abbreviation for ‘left surround’. The left rear speaker in a
5.1 surround system.

MADI:
Abbreviation for ‘multi-channel audio digital interface’.
Master bay:
Control area for masters, automation, comms, monitoring etc.
Also contains the primary navigation zone.
Masters:
The three master channels (mono and stereo left and right) in the
master bay.
MB:
Abbreviation for ‘megabyte’.
MC:
Abbreviation for ‘master controller’.
Meter:
Visual device to indicate the level of a signal.
Meters screen:
One of the GUI screens. This is the default screen of the
master bay.
Mic:
Abbreviation for ‘microphone’.
Microphone:
Device for converting sound waves into audio signals.
MIDI:
Acronym for ‘musical instrument digital interface’. A digital signal system
standard that facilitates integration of musical instruments, such as synthesizers
and guitars, with computers.
Mix:
1. A signal that contains a combination of signals, such as a pair of stereo
signals with numerous effects. 2. The act of creating such a combination.
3. A type of bus. See Bus.
Mix bay:
Control area for outputs and groups.
Mixer:
1. A console or other device that blends input signals into composite
signals for output. 2. An engineer/technician who carries this out,
especially during a live performance.
mm:
Symbol for ‘millimetre’ (one thousandth of a metre).
MON:
Abbreviation for ‘monitor’, used to describe a control centre being used to
mix the signals sent to the stage monitor speakers.
Monitor:
1. Speaker(s) used for listening to a mix or live audio. 2. The act of
listening to a mix or live audio.
Monitor A:
Primary monitor bus system.
Monitor B:
Secondary monitor bus system.
Monitors:
Control area on the master bay for monitoring the A and
B signal paths.
Mono:
A single signal.
Mute:
Function that allows a channel’s signal to be silenced.
Mute safe:
Function that means a mute cannot be controlled by scene recall or
auto-mutes.
N
N/A:
Abbreviation for ‘not applicable’.
nm:
Symbol for nanometre (one billionth of a metre).
Normalise:
To boost the amplitude of a digital sound so that it is as high as it
can be without clipping (0 dB).
Normalisation:
An automatic process whereby the gain of all program material
is adjusted so that the peak level will just arrive at 0 dB.
Normalised connection:
Also known as ‘normalled connection’. A connection
that allows a signal to pass through it when no plug is inserted in it, but breaks
the connection when a plug is inserted.
Normalising:
The process of making audio files the same volume.
NVRAM:
Abbreviation for ‘Non-volatile random access memory’. this is the
general name used to describe any type of RAM that retains its information when
power is switched off. For example, flash memory.
O
O/B:
Abbreviation for ‘outside broadcast’.
Oct:
Abbreviation for ‘octave’.
Octave:
A difference in pitch where one tone has a frequency that is double or
half of the frequency of another tone.
ohm (Ω):
Unit of electrical resistance.
OS:
Abbreviation for ‘operating system’.
OSC:
Abbreviation for ‘oscillator’ or ‘oscillation’.
Out of phase:
1. A signal, being similar to another in amplitude, frequency and
wave shape, but offset in time by part of a cycle. 2. 180° out of phase or having
opposite polarity. See Phase.
Outboard:
External, as in an ‘external device’.
Outboard equipment:
