Introduction - Lexicon PCM 80 - REV 1 DUAL FX User Manual

Thank you for your purchase of the PCM 80 Dual FX Algorithm Card. Dual FX
processing brings even greater control capabilities to the PCM 80, along with the
sonic clarity you expect from Lexicon.
The Dual FX algorithms offer uncompromised stereo multi-effects combined
with unparalleled flexibility and ease of use. Twenty-five new algorithms are
provided on the PC card, along with 250 exciting new presets.
Each Dual FX algorithm contains two independent effect blocks — one of five
stereo reverbs and one of five different stereo multi-effects blocks with four
voices of delay, panning, feedback, etc. Each algorithm also has the full set of
modulation and patch features introduced in V1.00 of the PCM 80.
Configuration and routing control is provided by a dedicated Submixer incorpo-
rated into each algorithm. Any combination of reverb and effects blocks can be
arranged in any configuration simply by changing the Submixer's controls. As
the Submixer has continuously variable controls, you can alter the configura-
tions on the fly — changing, for example, from reverb-into-effects to effects-into-
reverb.
The Submixer appears as a new row on the otherwise familiar PCM 80
parameter matrix. Three basic Submixer controls are provided: Sends, Re-
turns, and Routing. Any configuration can be achieved by simply adjusting
these three parameters.
Sends control the eight levels feeding into the reverb and effect blocks.
Returns control the eight levels feeding from the reverb and effect blocks.
Routing controls the configuration of all inputs and outputs to allow the two
effects blocks to be placed in series, parallel, or reverse series.
The Submixer row also contains controls for each block: Input Level, Input
Width, Output Width, Output Level, High Cut and Low Cut filters, and Wet/Dry
Mix. All of the Submixer parameters are continuously variable and can be
controlled in real-time by any PCM 80 patch source.
The 25 Dual FX algorithms are made up of combinations of the following 4-voice
Effect and Reverb blocks.
FX
Glide (glide/ 4-voice delay)
M-Band (4-band EQ/ 4-voice delay)
Chorus (4-voice chorus/ 4-voice delay)
Res1 (4-voice res1/4-voice delay)
Res2 (4-voice res2/4-voice delay)
These effects and their associated parameters will all be familiar to PCM 80
users. The 4-voice effects are slightly pared down versions of the PCM 80 6-
voice effects, and the Rvb effects are identical to those in the PCM 80.
