    Reference Lexicon This allows a soloist to be increased in level without changing the apparent distance. Ambience can be used in a recording situation any time a close-miked sound is undesirable. When using Ambience in a mix, it is best to use a stereo send to the PC-90, carefully matching the panning of the various close-miked sources to their positions in the mix.

  • Page 74: The Parameters

    Lexicon Studio 12T System User Guide for Macintosh and PC Reference The Parameters The PC-90 has a wide range of parameters to control the sound of your algorithms. Not all parameters are found in all algorithms. Chorus In the Concert Hall algorithm, Chorus randomizes delay times and introduces modulation to make reverberation sound less metallic.
  • Page 75 Reference Lexicon Depth In the Concert Hall algorithm, Depth sets the output amplitude envelope, changing the listener’s perspective from the front to the rear of the hall. Diffusion A Diffusion control is provided in all algorithms. It controls the degree to which initial echo density increases over time.
  • Page 76 Lexicon Studio 12T System User Guide for Macintosh and PC Reference Infinite In the Room algorithm, this control is provided to turn the Infinite effect On or Off. Input Lvl InLvl controls the level of the unprocessed (dry) signal into the effect.
  • Page 77 Reference Lexicon Reverb Level Reverb Level sets the amount of reverberation in the processed signal. It is normally FULL, but may be reduced for effects where the pre-echoes should dominate. Reflect Delays In the Chamber and Inverse algorithms, L Refl and R Refl provide pre-echoes to the left and right channels.
  • Page 78 Lexicon Studio 12T System User Guide for Macintosh and PC Reference Slope In the Inverse algorithm, Slope determines the shape of the reverb envelope. When set to 0, the level of reverb remains unchanged over its duration, then cuts off abruptly (depending upon the amount of Diffusion in use).
  • Page 79 Reference Lexicon Notes on Preset Design PC-90 incorporates the results of a great deal of research into acoustics and reverberation. Reverberation, or reflected sound energy, gives recorded music a sense of being performed in a real acoustic location. Using the Size and Spread Parameters In the PC-90, the Size and Spread controls allow adjustment of the buildup and decay of the initial part of the reverberation envelope.
  • Page 80 Lexicon Studio 12T System User Guide for Macintosh and PC Reference As Shape is raised further, the buildup and sustain remain similar, but now a secondary sustain appears in the envelope, at a lower level than the first. This secondary plateau simulates a very diffused reflection off the back wall of a hall, and is effective in creating a sense of size and space.
  • Page 81 Reference Lexicon Next use Mid Rt to fine-tune the amount of time the reverberation takes to die away at the end of musical phrases. Actual halls vary a great deal in their Mid Rt values. The setting of Bass Mult is also critical in matching the sound of an existing hall.

  • Page 83 Appendix A Lexicon PC-90 Cascade Routing PC-90 routing allows you to daisy-chain the PC-90 reverb engines to make a dual-engine reverb. This is useful for creating your own “super-reverbs”, for example, using Machine 1 for early reflections and Machine 2 for the main reverb. In the early days of digital reverberation, creating your own reverbs was essential to get great-sounding reverb.
