Glossary of Terminology
Layers
Layers allow the faders on the surface
to change the paths they are controlling.
On each layer, a different path can be
attached to and controlled by a given
fader. There can be up to 24 layers on
the Artemis surface. Given an example
surface containing 64 faders and using
6 layers, the user may control up to 384
paths with the faders simply by changing
layers.
LineOutput
A type of Main output bus, that is
interruptible with output tone and talkback
selections.
MixBus
When multiple signals are routed to a bus
they are mixed together. This allows the
combined signal to be processed, routed
or have its level controlled from a single
location.
MADI(MultichannelAudioDigital
Interface)
A coaxial or optical transmission medium
providing a 56 or 64 channel capacity.
The MADI standard (AES 10) allows
simple high density connectivity between
different manufacturer’s equipment.
MADI is interfaced with an Artemis
system via a Hydra 2 MADI I/O unit.
Main
A main is an output bus, a final point at
which signals are mixed and affected
before they leave the console. Each
main path can be accessed for external
patching via a Desk Output and a Line
Output.
MainApplication
The touchscreen based configuration PC
application that provides additional access
to many controls and allows system
settings to be configured.
MicInputHeadroom
The amount of headroom above the
mic gain setting, used as a safety net
in the case of sudden high signal level.
The headroom is currently fixed at 36dB.
A high headroom offers greater safety at
the expense of slightly more noise.
MixMinusBus
A dedicated bus used for simple yet
powerful creation of mix minus feeds.
A unique mix is created for each recipient
which consists of the whole mix minus
bus, minus their own contribution.
Each mix minus feed is sent from a
channel or group’s direct output.
ModeButtons
The mode buttons allow the operating
mode of each fader panel on the surface
to be switched.
OnAirMode
On Air mode allows certain operational
functions to be activated or inhibited when
the system is switched in to it.
OnlineDocumentation
The touchscreen based configuration PC
application for displaying and providing
interaction with Calrec documentation and
training materials.
Port
A port refers to any physical audio input or
output in a Hydra 2 I/O box. Ports can be
of any form of analogue or digital I/O. In
the case of analogue signals, a single port
relates to a single signal in the system.
Where digital signals are connected,
multiple signals become available for each
port. A single AES3 port provides two
signals, SDI can provide up to 16 signals
(or more with Dolby E decoding) and
MADI can provide up to 64 signals.
Patch
A patch is a connection made between
a source and a destination in the system.
For example an input port may be patched
to one or more channel inputs, or a main
output may be patched to one or more
output ports.
Path
A generic term that refers to a DSP
process in the system. A signal present at
an input port must be routed to a path in
order for it to be processed and then sent
back out of the system. Paths include
channels, groups, auxs, tracks, mains,
talkback and monitor paths. Paths can
be routed to other paths, for example a
channel path can be routed to a group
path and a main path simultaneously.
PFL
Pre-Fade listen. A function to allow a
signal to be heard before it has it’s level
altered by a fader. Multiple PFL signals
can be sent to the PFL bus.
PoweroverEthernet(POE)
A technology used to provide power to
equipment through the same Ethernet
connection that carries information.
Pre-Selectors
Part of the monitoring controls on the
surface, Pre-Selectors allow a number of
sources to be preset, ready to be sent to
the main control room loudspeakers and
meters.
Presets
Path presets allow you to save a complete
copy of all a path’s parameters. This
preset can be recalled onto any other path
at any time.
PSUModule
The PSU module provides power to the
rack and the other modules contained
within it.
