Glossary of Terms

Access key
The Access key is the located below the ON/CUT and AFL key on the fader strips, engraved with
a triangle or the fader number. It is used to identify signal paths for various actions such as
routing.
AFU
AFU is an abbreviation of Assignable Facilities Unit. This is the "channel strip" panel that is called
to a path by pressing the fader's access key. It has the normal channel strip controls such as EQ
and dynamics.
Allocation
Libra Live uses a pool of processing that can be allocated to input and output path processing
according to a session's needs. The processing is "allocated" to the different functions (signal
paths, EQ etc) using an Encore program called Desk Editor. The allocation is stored as a "desk
configuration" also known as a "mix setup" which can be recalled, edited or copied as necessary.
Allocation mutes the console while the signal processing for signal paths and processing is built.
In the early days of digital consoles digital processing was expensive and it was necessary to be
careful how the processing resource was used. These days consoles are usually supplied with
sufficient processing for the full complement of EQ and dynamics to be available in every
channel.
Alpha Display
The term alpha or alpha display refers to the digital alphanumeric displays used on the console
surface.
For instance, the Assignable and Pan Logicators on the fader strips each have an associated
eight character alpha display.
Assignment
After signal paths have been created, they can then be "assigned" to physical faders using the
Desk Designer page in Desk Editor. Paths can also be assigned and re-assigned using the setup
mode on the control surface. Signal paths can exist and pass audio without being assigned to a
physical fader. Changing assignments does not affect the audio and can be done live.
Automation
Libra Live has two automation systems: Snapshot automation stores and recalls control positions
under manual control; Dynamic automation records and replays control movements against
timecode. The default automation for Libra Live is Snapshots, which is switched off when
Dynamic automation is switched on.
Automation Mode (Dynamic Automation)
This refers to the states of controls in dynamic automation when recording and re-playing control
moves against timecode. The basic Automation Modes are Record, Play, Touch record (when
REC and PLAY are on together - sometimes known as update) and Isolate (when the automation
for individual controls is switched off).
Automation modes are only relevant when Dynamic Automation is switched on.
