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 processing 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, another 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 collection of similar programs derived from one or more algorithm. For example, the Halls bank contains reverberation programs that simulate large spaces, while the Mastering bank contains programs for level adjustment 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 configured to operate independently, or they can be combined to function as a single machine. The configuration 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. 2-2

Basic Operation Operating Modes The 480L is always in one of the following four operating modes: Machine Operation Mode Program Preview Mode Register Preview Mode Control Mode The 480L always powers up in Machine Operation Mode. Each mode, and the paths for entering and exiting it are described below. Machine Operation Mode Press the PROG or the REG button, then press VAR. This mode allows you to: • View the machine currently being addressed by the LARC. • Display the program or preset currently running in the machine. • View and/or alter parameters. Program Preview Mode Press the PROG button. Press the BANK button to view program banks. Press the PROG button to view programs in the bank. This mode allows you to: • Select presets. Register Preview Mode Press the REG button. Press the BANK button to view register banks. Press the REG button to view programs in the bank. This mode allows you to: • Select, store, and recall programs from registers. • Address a cartridge in the mainframe cartridge slot. Control Mode Press the CTRL button. To exit, press CTRL, then press PROG, then press REG. This mode allows you to: • View system status. • Set machine and input configuration. • Alter input and set digital operation. • Address the register transporter. • Name programs. • Create Dynamic MIDI patches. • Transmit MIDI Program Change messages. • Enable MIDI SysEx Automation * Transmit MIDI Bulk Dumps 2-3
