INTRODUCTION

Congratulations on your purchase of a Yamaha SPX90II Digital Multi-Effect

Processor. The SPX90II is an amalgam of advanced acoustical research and

digital technology designed to provide musicians and home recording enthusiasts

with a wide range of exciting effects.

The SPX90II Digital Multi-Effect Processor utilizes highly refined LSI (Large

Scale Integration) technology to create natural reverberation. Not only is its

assortment of 30 preset effects comprehensive enough to suit most studio and

performcmce applications, the SPX90II also allows you to create up to 60 ad

ditional effects and store them for instant recall.

Your SPX90II can create effects for beyond mere reverberation, though that

in itself is of a truly superior quality. A variety of echo, delay, and special effects—

each with comprehensive parameter adjustments—can be accessed at the touch

of a switch. And as the SPX90II is MIDI-compatible, it can be programmed

to apply separate reverberation effects to a variety of MIDI-compatible in

struments.

Your SPX90II Digital Multi-Effect Processor will prove extremely useful in a

variety of applications: acoustic electric, PA, MIDI instrument, and home re

cording systems. In order to take advantage of the vast potential of this com

ponent, we urge you to study this manual before connecting the SPX90II to your

system.

We at Yamaha thank you, and wish you years of enjoyment with your

SPX90II.
