Introduction - Lexicon PCM 81 - REV User Manual

Thank you for your purchase of the PCM 81, one of Lexicon's most powerful and
versatile digital effects processors. The PCM 81 brings you exciting new effects
with extensive processing and control capabilities, and uncompromising sonic
clarity.
The PCM 81 contains a built-in library of 300 preset programs that provide a
comprehensive array of effects ranging from beautiful and lush to completely
wild. The presets are organized into 6 Banks of 50, and functionally grouped for
a wide range of applications. Be sure to experiment with all 300 presets to get
a feel for the full range of PCM 81 capabilities.

Every preset has one or more of its parameters patched to the front panel
ADJUST knob, giving you instant control over the primary aspect of the effect
— without going into Edit mode. In the preset, Concert Hall, for example, Mid
Reverb Time is patched to ADJUST. When you turn the knob, you will adjust the
reverb decay. In Prime Blue, ADJUST is patched to several parameters, so that
turning the knob changes the effect from a tight chorus, to a chorus with
recirculating echoes and, finally, into a reverb.
The PCM 81 uses 17 stereo algorithms to create different types of effects. Each
algorithm includes an uncompromised stereo reverb effect, as well as several
voices of additional stereo effects. There are three general classes of algorithm:
4-Voice, 6-Voice and Pitch. The 4-Voice algorithms: Concert Hall, Plate,
Chamber, Inverse and Infinite each combine a specific type of reverberation with
a 4-voice, general purpose, stereo effect "toolbox", as well as additional post-
processing for the reverb. The 6-Voice algorithms: Glide>Hall, Chorus+Rvb, M-
Band+Rvb, Res1>Plate and Res2>Plate each combine a specific type of
reverberation with a specialized 6-voice stereo effect. The Pitch algorithms:
Quad>Hall, Dual-Chmb, Dual Plt, Dual Inv, Stereo-Chmb, VSO-Chmb and Pitch
Correct each offer a unique type of pitch shifting, combined with an
uncompromised Lexicon reverb.
Many of the PCM 81 algorithms include parameters that make it possible to
create dynamic spatialization effects for 2-channel or surround applications.
Check out the Ambience Effects in Bank P1 and the Spatial Effects in Bank P2
for examples. The Dual FX Pitch algorithms have dedicated Submixer controls
that allow instant reconfiguration of the reverb and effects blocks.
The PCM 81 gives you a unique set of tempo controls.Tempos can be tapped
in with the front panel Tap button (or an assigned controller) or "dialed-in", in
BPM (beats per minute) on the display. The PCM 81 also lets you generate MIDI
clock from your tempo, as well as receive MIDI tempo from an external
sequencer or drum machine. In the PCM 81, tempo can control LFO speeds and
