Advanced Hardware for Superior Sound
20-bit analog-to-digital and digital-to-analog conversion technology- sampling at 44.1kHz. Frequency response extends all the way from 20 Hz to 20 kHz; dynamic range is an extraordinary 106dB; noise and distortion are neglible.

Stereo Configuration with Balanced Inputs and Outputs
A true 2-in/2-out stereo configuration that allows stereo sources to be processed without disrupting the original stereo image. Stereo inputs and outputs are all electronically balanced, with XLR and TRS phone jack connectors.

Preset, Internal, and Card Memory
180 memory locations "on board". 80 of these are read-only memory. The remaining 100 are writable memory locations. Plug-in memory cards hold an extra 100 effect programs each.

Three-stage Effect Configuration
In addition to the main effects, the SPX990 provides programmable pre and post effects that can be used to refine and polish your sound.

In-depth Programming Power
The SPX990 has 4 programmable pre effects, 36 programmable main effects, and 3 programmable post effects.

Tempo-based Delay Time Programming
Delay time parameters can be programmed in terms of tempo or note length. Delay time can also be entered via a footswitch or MIDI clock data.

Superior Pitch Precision
The SPX990 achieves faultless pitch tracking through a new dynamic waveform analysis technique. In addition to the simple parallel pitch tracking the SPX990's "intelligent" pitch change creates appropriate harmony based on a specified key and scale type.

External Parameter Control
The SPX990 allows two selected parameters from each program to be assigned to two external MIDI controllers.

MIDI Control
The SPX990 allows MIDI selection of all programs, and real-time control of up to two selected effect parameters at the same time.
