One year after the success of the original Yamaha SPX-90 (released in very late 1985/early 1986), Yamaha introduced the Yamaha SPX-90II. The two processors are identical in terms of specifications and effects on offer, the only difference is the Yamaha SPX-90II has double the memory for delays etc.

The Yamaha 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 Yamaha 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 efects comprehensive enough to suit most studio and performance applications, the SPX90II also allows you to create up to 60 additional effects and store them for instant recall.

The 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 instruments.

Your Yamaha SPX90II Digital Multi-Effect Processor will prove extremely useful in a variety of applications: acoustic electric, PA, MIDI instrument, and home recording systems. In order to take advantage of the vast potential of this component, we urge you to study this manual before connecting the SPX90II to your system.
