Yamaha SPX 900 Multi-FX

The Yamaha SPX-900 multi-effects unit features 50 preset effects programmes and 49 User memory locations. Editing is simple using the front panel buttons.
The SPX900 provides simultaneous processing of up to 5 effects at one time. With a sampling frequency of 44.1 kHz, it delivers a full frequency response from 20 Hz to 20 kHz.
Each program has a range of “main” parameters that tailor the effect to a specific application. Individual two-band EQ and dynamic filter parameters are also provided for each effect program. In addition, the SPX900 offers a group of internal parameters that provide custom control over each effect. Finally, level parameters balance between direct sound, and set overall output level.
As well as a rich selection of reverb simulations, the multi-effect programs combine compressor, distortion, equalizer/dynamic filter, reverb, echo, chorus, symphonic or Aural Exciter effects with programmable parameters for each effect.
