Unpacking and Inspection
After unpacking the 480L and LARC, save all packing materials in case you ever need to ship the unit. Thoroughly inspect the 480L, LARC, and packing materials for signs of damage in shipment. Report any damage to the carrier at once.
Precautions
The Lexicon 480L is a rugged device with extensive electronic protection. However, reasonable precautions applicable to any piece of audio equipment should be observed. [. . . ] It is designed primarily for use in film and video post-production environments.

The Pitch Change Programs
The Pitch Change program located in Bank 8 is a stereo or two-channel mono pitch shifter with several useful effects, including predelay, feedback, and glide. PCH (Pitch Interval R) This control performs the same functions as the other PCH control, except that it is only active in Mono mode, in which it adjusts the right channel. FIN (Fine Pitch R) This control performs the same functions as the other FIN control, except that it is only active in Mono mode, in which it adjusts the right channel. Page Two PDL (Predelay L) PDL adjusts the length of a delay line in series with the left input. The range is zero to over 800 ms, with a fine scale available when the button is pushed. In stereo mode the two predelays must be set to the same value, or the signals will not be in phase. PDR (Predelay R) PDR is the same as the PDL, except that it acts upon the right channel. FBL and FBR (Feedback Left and Right) FBL and FBR control the amount of feedback from the output of the pitch shift to the input of the predelay line. The control is at zero feedback when centered, and is adjustable from 0 to +99%. Some very useful effects can be obtained by combining pitch shift, delay, and feedback.
About the Pitch Change Parameters
Page One MOD (Stereo/Mono Mode) MOD selects stereo or mono mode. Move the slider all the way up to select mono, and down to select stereo. In stereo the two channels are linked, pitch shifting by the same amount and splicing at the same time. SNC (Play Sync) Normally the channels are in sync, but if PCH, FIN, or GL are moved frequently they can get out of sync. PCH (Pitch Interval Stereo/Left) PCH adjusts the pitch interval of both channels in stereo mode, and the left channel in mono mode. The exact tuning can be altered by the fine pitch control, and the exact pitch shift in intervals and cents is displayed. The fine control must be set to the exact middle of its range if perfect pitch intervals are to be obtained.

Bank 8: the Pitch Change and Doppler Programs Page Three MIDI (MIDI Pitch Event Left) MIDI Pitch Event provides a fast link between a MIDI Note Event and interval pitch shifting. By establishing a patch with NOTE EVENT as source and PITCH EVENT as destination, the amount of pitch shift can track incoming notes in semitone intervals. REF (Reference MIDI Note Left) REF sets the MIDI Note Value for no pitch change, NULL + 0C, when under MIDI control. MIR (Pitch Mirror Left) MIR selects the direction of MIDI pitch control. GLL (Glide Stereo/Left) GLL affects both channels in stereo mode, and the left channel in mono mode. This allows a glissando to be performed, either manually with the LARC, or via MIDI. [. . . ] In the sampler and doppler programs, when SRC is set to NOTE EVENT, this control sets the LOW NOTE. PRM/HIGH (Parameter/High Note) When SRC is set to a MIDI controller, last note, or last velocity, this slider allows control of the parameter selected with DST. In the sampler and doppler programs, when SRC is set to NOTE EVENT, this control sets the HIGH NOTE.
When registers are protected, they cannot be copied to, moved to, cleared, or otherwise erased. Advancing the slider selects a program to load automatically when power is interrupted, then restored. [. . . ]
