(upper-left corner).
GUI screen: One of the M32’s two screens, which comprise the GUI.
H
HPF: Abbreviation for ‘high pass lter’. A lter that removes lower frequencies
from a signal, leaving the higher frequencies unaected.
Hum: Undesirable low frequency tone present in a signal due to grounding
problems or proximity to a power source.
Hz: Symbol for ‘Hertz’. A unit of frequency equal to one cycle of a sound wave
per second.
I
I zone: Area on the master bay that contains the operator-assignable
eects controls.
I/O: Abbreviation for ‘input/output’.
ID: Abbreviation for ‘identication’.
Ident: Scale marking, or gradation, around a control knob to help indicate the
current setting and to assist in accurate adjustment.
Impedance (Z): Opposition to the ow of alternating current in a circuit,
measured in ohms.
K
Kernel: For computers, the kernel is the central component of most
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 eects’. 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 eects 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.
M
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 eects. 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 les 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 o. For example, ash memory.
O
O/B: Abbreviation for ‘outside broadcast’.
Oct: Abbreviation for ‘octave’.
Octave: A dierence 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 oset 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: External equipment used with the M32 Control Centre,
but that is not part of it.
Output: 1. The signal put out by a device. 2. The physical location of where a
device sends out a signal.
