For over 30 years, Lexicon has been considered a pioneer in digital audio.With more experience than any other manufacturer, it’s no surprise that the PCM 81 Digital Effects Processor and the PCM 91 Digital Reverberator represent the most advanced systems in their class. Lexicon’s unique dual DSP platform enables the PCM 91 to offer the highest quality reverb, and allows the PCM 81 to combine reverb with powerful, flexible effects. Professional digital inputs and outputs (AES/EBU and S/PDIF) on both units, coupled with the legendary “Lexicon Sound”, makes the PCM 81 and PCM 91 an essential combination.
Easy Operation
The PCM 81 and PCM 91 offer Tap Tempo control of delay lines as well as several rhythmic variations on the tap. Tempo can be “dialed-in” in beats-per- minute, MIDI clock can be generated from tap, or received via MIDI from an external sequencer or drum machine. Tempo can also control LFO speeds and time switches, allowing modulations to be synchronized with music. Independent rhythmic values can be set for each parameter within the same program. Tempos can be read as both rhythmic values and absolute time values. The PCM 81 also offers more than 20 seconds of stereo delay.
The PCM 81 and PCM 91 are as simple to operate as they are pleasurable to listen to. Just load a preset and a useful parameter will become instantly available on the Adjust knob. The next level was designed for professionals who want to further customize programs, but lack the time to wade through the myriad of available controls. In this mode, as many as 10 of the most logical parameters in a given effect are easily accessible for customization. For the sound designer, another mode allows access to the full Editing matrix available in both units, as well as a user-assignable Soft Row in which to store favorite parameters. It also provides access to the extensive modulation capabilities of the PCM 81 and the dynamic reverb aspects of the PCM 91.
Dynamic Patching
The PCM 81 and PCM 91 raise Dynamic Patching to a new level, providing unprecedented control over the effects. Dynamic Patching gives these processors a truly unique set of capabilities, from modulating sounds, to producing unusual and ethereal spaces, to altering the attack and decay characteristics of the sounds. With Dynamic Patching it is possible to exceed simple modulation effects. The Dynamic Patching matrix maps data from 143 possible control sources to any effect parameter. These sources include 126 different MIDI controllers, as well as external sources such as footswitches and footpedals. Internal controllers include Tempo (both internal Tap and external MIDI clock), LFOs (Sine, Cosine, Square, Triangle, Pulse, and Sawtooth), Time Switches, Latch, AR Generator, and Left and Right Envelope Followers. Up to 10 patches can be created per effect. In a conventional patch scaling configuration, modulation occurs between maximum and minimum values. In the Dynamic Patching matrix, eight pivot points can be established to create complex and interesting modulation paths.
Card Slot
The PCM 81 and PCM 91 are both equipped with an industry-standard PCMCIA card slot, allowing users to store personal programs and setups on cards. For the PCM 81, adding Lexicon’s Dual FX algorithm and specially designed preset cards for the PCM 80 (compatible with the PCM 81) increases its number of algorithms to more than 40 and presets to nearly 800.
PCM 81 Effects
The PCM 81 and PCM 91 feature professional AES/EBU and S/PDIF digital audio input and output formats. S/PDIF coaxial and AES/EBU XLR digital output connectors can be used simultaneously, doubling digital audio outputs.
The PCM 81 has everything that made the PCM 80 the top choice among studio effects processors. In addition, it offers more effects, more algorithms, and full AES/EBU input and output. Two digital signal processors; Lexicon’s proprietary LexiChip® for reverb, and a second DSP engine to handle other effects, create versatile effect combinations without compromising sonic clarity. The PCM 81 offers more than all other processors in its class with; 24-bit internal processing, a true stereo signal path, balanced analog inputs and outputs,AES/EBU and S/PDIF digital inputs and outputs, the power to combine analog and digital outputs, extensive modulation capabilities, and 300 presets.
PCM 81 Sounds
The PCM 81 boasts an enormous selection of sounds. Each combines uncompromised stereo reverb with several voices of additional effects. A full complement of Pitch Shifters provides unique special FX as well as doubling, quadruple tracking, Chorus, and Pitch Correction within a range of three octaves up or down. With 300 presets, the PCM 81 allows instant access to Pitch, Reverb, Ambience, sophisticated Modulators, up to 20-second stereo Delays, and Dynamic Spatialization effects for 2-channel or surround applications. Its presets were designed to accommodate a wide range of applications, from effects designed for musical uses and recordings to effects designed specifically for pitch correction, sound effects, and video post- production. The PCM 81 also features updated versions of classic Lexicon effects such as Concert Hall and Tiled Room.
PCM 81 Algorithms
The PCM 81 utilizes 4-voice, 6-voice, and Pitch algorithms to create effects. The 4-voice algorithms; Chamber, Concert Hall, Infinite, Inverse, and Plate. Each combine a specific reverb type with a 4-voice stereo “effect toolbox” called the Reverb Shell, which provides post-processing for the reverb. For example, it is possible to produce a Ghost Flange by assigning a Modulated Delay to an Inverse Reverb (to Detune it). The 6-voice algorithms; Chorus + Reverb, Glide, Hall, Multiband + Reverb, Res 1 > Plate, and Res 2 > Plate, combine a specific reverb type with a specialized 6-voice stereo effect. In these algorithms, it is possible to combine the shimmer of a multi-voice chorus with a lush reverb tail (as in Wet Chorus). The on-board Pitch algorithms encompass all Pitch and Vocal Correction algorithms and effects available in the PCM 80 via plug-in cards. Seven algorithms include Pitch Correct for correction of monophonic sources, and Stereo Chamber for full stereo pitch-shifting with Chamber reverb. A powerful submixer is built into the Dual Chamber, Dual Inverse, and Dual Plate algorithms for flexible ordering and routing of two independent voices of pitch-shifting with reverb.A 4-voice Quad > Hall algorithm provides four independent pitch-shift voices with full stereo reverb, and a VSO-Chamber algorithm provides stereo time and pitch correction with Chamber reverb and variable speed pitch control (in percent).
Lexicon’s research into the physics of acoustics is embodied in the Random Hall algorithm. Echograms of real halls have dispelled the myth of pre-delay and early reflections. In actual spaces, there is no empty interval between the arrival of direct sound and the maximum reverb density filled by early reflections. Instead, ambience builds gradually, with diffuse and complex reflections that do not color the timbre of sound like fixed-delay taps. Random Hall’s unique Shape, Size, and Spread parameters control the build-up and decay of the ambient envelope. Size determines how large the space will be. Shape controls the contour of the ambient build. At its highest settings, it provides an inverse envelope for effects and gating. Spread controls the duration of Shape, setting the build-up and sustain. Precision filters provide spectral control of reverberation time, and unique Spin and Wander parameters add random movement ensuring smooth reverberant decay. Lexicon’s classic Concert Hall algorithm has been enhanced with Spatial EQ and a Compressor to increase its versatility. The Rich Plate algorithm provides simulated plate reverberation, as well as new variations on this classic effect. The Ambience algorithm provides effects tailored specifically to the post-production environment, permitting accurate matching of previously recorded ambience. This allows new elements to blend seamlessly, and sound effects, dialog, or music to be placed realistically at different positions in the "space."
PCM 81 Dynamic Spatialization
Two independent spatial processors accommodate the placement of effects virtually anywhere between or beyond the loudspeakers. Effects can also be located dynamically, creating different spaces that change with the music.
The PCM 81 takes where the PCM 80 left off, and adds AES/EBU Digital I/O, includes algorithms and presets from the Pitch FX and Vocal Fix Cards, and adds 24-bit converters for even higher quality audio.
