    Handling the The Dual FX Algorithm Card is a standard PC card designed to be used with the Lexicon PCM 80 (version 1.10 or higher). Care and handling of the card, as well Algorithm Card as some routine precautions are noted here. Please review these before using the card to avoid damage to the card, as well as error states in the PCM 80.
  • Page 9 PCM 80 Dual FX User Guide Lexicon MIDI SysEx register dumps require that the algorithm card used to create the effect(s) be loaded. Be aware that, if you create a bank of registers with effects created from more than one algorithm card, you will need to perform separate SysEx dumps for each card used.

  • Page 10: Loading The Dual Fx Algorithms

    Dual FX Card Operation Loading the Dual FX Algorithms In order to run the Dual FX algorithms, the software must be loaded into the PCM 80’s “extension” memory. To do this: If the PCM 80 is turned off: Insert the Dual FX algorithm card into the PC card slot. Power up the PCM 80.

  • Page 11: Loading The Dual Fx Presets

    PCM 80 Dual FX User Guide Lexicon Loading the Dual FX Presets Once the software is loaded, the PCM 80 will have access to the additional program banks available on the algorithm card. These extension memory banks are labeled with an X.

  • Page 12: Using The Submixer

    Dual FX Card Operation Using the Submixer New configuration control is added to basic PCM 80 functionality with the Dual FX Card. The most significant aspect of this expanded control is the addition of a Submixer which is incorporated into each algorithm. This Submixer lets you arrange any combination of reverb and effects blocks in any configuration simply by changing the three main Submixer controls: Sends, Returns and Routing.

  • Page 13: Sends

    PCM 80 Dual FX User Guide Lexicon The Submixer appears as row 1 on the parameter matrix of each of the 25 Dual FX algorithms. The first three parameters in the row are the basic Submixer controls: Sends, Returns, and Routing. Any configuration can be achieved by simply adjusting these three parameters.

  • Page 14: Routing

    Dual FX Card Operation Routing The Routing parameter provides continuously variable control of the FX and Rvb effect routing: Rvb and FX in parallel, Rvb into Fx (series) and FX into Rvb (reverse series). This parameter has a range of 0–400. The value of this parameter determines the routing/ordering of the stereo Rvb and FX effects.
  • Page 15 PCM 80 Dual FX User Guide Lexicon Stereo Series 2 • The main stereo inputs are sent into the FX block. • The stereo output of the FX block is sent into the stereo inputs of the Rvb block. • The stereo output of the Rvb block is sent to the main left and right outputs.

A mono mix of the FX output is sent to the left main output.

Each of these blocks has its own set of Controls controls, shown in the diagrams below. Rvb Block FX Block These effect block controls are also found in the Submixer row of each...
  • Page 21 PCM 80 Dual FX User Guide Lexicon These parameters are described below, in the order in which they appear in the Submixer row. (All other effect parameters are identical to those in the PCM 80, and are described in the PCM 80 User Guide.) RvbMix, FX Mix These are independent wet/dry mix controls for the Rvb and FX effect blocks.

  • Page 22: The Dual Fx Blocks And The Algorithms

    The Dual FX Blocks and the Algorithms The Dual FX Blocks and the Algorithms The Dual FX Card uses five Reverb blocks and five Multi-Effect blocks to produce 25 Dual FX algorithms. The five reverb blocks and the five multi-effect blocks are described on the following pages.

  • Page 23: The Reverb Blocks

    Lexicon PCM 80 Dual FX User Guide The Reverb Blocks Concert Hall This algorithm is identical to the Concert Hall algorithm in the PCM 80. It emulates a real concert hall. The reverberation is very clean, and designed to remain behind the direct sound — adding ambience, but leaving the source unchanged.

  • Page 24: Chamber

    The Dual FX Blocks and the Algorithms This algorithm is identical to the Chamber algorithm in the PCM 80. It produces Chamber an even, relatively dimensionless reverberation, with little change in color as the sound decays. The initial diffusion is similar to the Concert Hall algorithm, but the sense of space and size is much less obvious.

  • Page 25: Infinite

    Lexicon PCM 80 Dual FX User Guide This algorithm is identical to the Infinite algorithm in the PCM 80. It is acoustically Infinite similar to the Chamber algorithm, with the addition of an Infinite parameter. When this parameter is turned on, the input to the reverberator ramps off. With Infinite on, the reverb tail remains constant, creating strange and useful reverb effects.

  • Page 26: The Fx Blocks

    The Dual FX Blocks and the Algorithms The FX Blocks Glide A stereo pair of 2-tap gliding delays feeds four individually adjustable delay voices. Each voice has its own level, feedback, delay, cross-feedback, and pan parameters. Glide is useful for creating such effects as stereo flangers, loop samplers, pitch modulation, etc.

  • Page 27: Chorus

    Lexicon PCM 80 Dual FX User Guide The Chorus effect has four separately adjustable voices — allowing the PCM 80 Chorus to sound like a rack of four digital delay boxes. Each voice has its own independently adjustable chorus depth and rate, level control, delay time,...

  • Page 28: M-Band

    The Dual FX Blocks and the Algorithms This effect features four separately adjustable voices, each with its own level M-Band control, delay time, low and high frequency filters, feedback and pan controls. Note also that, in this particular algorithm, the filters are within the feedback paths of the multi-band voices.
  • Page 29 Lexicon PCM 80 Dual FX User Guide The Resonant Chord The Resonant Chord effects use impulsive energy at the inputs to excite four Algorithms: resonant voices (notes). The level, pitch, duration, and high-frequency cutoff of Res1 and the overtones for each voice are separately controllable. Each voice can be Res2 panned independently.
