Lexicon 480L Owner's Manual

Glossary

• Mainframe Mainframe refers to a functional 480L
operating with one or more machines.
• Machine Each 480L HSP board is addressed in the
mainframe as an independent machine, or signal pro-
cessing engine. In addition, the 480L can recognize the
Lexicon 224XL and address it as another machine.
• Algorithm The 480L contains several algorithms.
An algorithm is a set of instructions that tells the 480L's
microprocessors how to process the input signal. One
algorithm produces effects, another reverberation, an-
other sampling, etc. Each Machine in the 480L can
process an algorithm independently from the other
machine.
• Parameter Each algorithm has a set of parameters
(controls) that uniquely characterize it. The settings of
the parameters can be changed to create radically
different sounds from a single algorithm.
• Program A group of specific parameter settings
permanently stored as separate programs in the 480L.
• Preset A group of specific parameter settings you
create by editing presets and storing the new set of
values.
• Register Nonvolatile RAM memory locations in the
mainframe, or in a removable nonvolatile memory
cartridge, for storing presets.

• Bank A bank is a collection of as many as ten
programs or registers. Program banks contain a collec-
tion of similar programs derived from one or more
algorithm. For example, the Halls bank contains rever-
beration programs that simulate large spaces, while
the Mastering bank contains programs for level adjust-
ment and digital equalization.
• Pages The LARC can display and provide slider
control for six parameters at a time. Because most
algorithms have more than six parameters, they are
grouped in blocks of six called pages. The PAGE
button provides access to each group of parameters.
• Control Mode The control mode contains several
pages of utility parameters and functions which are not
directly related to a single algorithm, such as sampling
rate, register transporter, program name function, etc.
The control mode is entered and exited by pressing the
CTRL button on the LARC.
• Configuration The 480L machines can be config-
ured to operate independently, or they can be com-
bined to function as a single machine. The configura-
tion is changed from the control mode. The 480L is
shipped in the single configuration.
• dBFS A digital signal at full amplitude, or registering
to the most significant bit.
