    A variety of echo, delay, and special effects—each with comprehensive parameter adjustments—can be access- ed at the touch of a switch. And as the SPX90 is MIDI-compatible, it can be programmed to apply separate reverberation effects to a variety of MIDI-compatible instruments.

    PRECAUTIONS NOTE: It is vital to read this section before using your SPX90 Digital Multi-Effect Processor. This unit utilizes state-of-the-art digital technology which, although designed to provide years of trouble-free use, requires careful handling.

    NOTE: If you attempt to store a program in one of the read-only preset locations (1 through 30), the SPX90 will display the “# 1 ~ # 30 READ ONLY” error message. : SPX90 has an Edit Title Function, so you can which allows you to provide your own titles for edited programs.

  • Page 11: Description Of Programs And Parameters

    DESCRIPTION OF PROGRAMS AND PARAMETERS The preset programs in the SPX90 fall into the following types: REV (Reverb), ER1 and ER2 (Early Reflections), DELAY, ECHO, MOD (Modulation), GATE, PITCH, FREEZE, PAN, VIBRATO and PEQ (parametric equalizer). Each of these program types has a specific selection of programmable parameters.

    Assuming the console used has independent effects or auxilliary send level controls on each input channel, it is possible to add the required amount of SPX90 effect to each input. It is also possible to use two SPX90 units for full stereo reverb and effects in a larger system.
  • Page 23 In a recording system it is most desirable to have the SPX90 input and outputs available at a patch bay where they may accessed and patched into virtually any part of the system. In some cases it might be best to have the SPX90 connected directly in line between the source and the mixing console inputs, while in other situations—final mixdown, for example—the SPX90 should be patched into the mixing console’s effects...
