The Yamaha SPX2000 is a professional rack-mount multi-effects processor and the flagship of Yamaha’s legendary SPX line, built for both live sound and studio use. It carries on the familiar interface and classic programs of its predecessors the SPX90, SPX900, SPX990, and others, while bringing a new level of quality through 24-bit/96kHz audio processing and Yamaha’s then-new REV-X reverb algorithms, known for their rich, smooth decay.
