Kurzweil KSP8 Multi-Bus Signal Processor

Winner of the EM Editors Choice award for Best Effects unit over $1,000.

The Kurzweil KSP8 multi-bus signal processor is an 8-channel effects system designed for the professional engineer, producer, or musician who requires high-performance effects, excellent sound quality, and unparalleled realtime control. It has over twice the processing power of KDFX, the world-class effects system found in Kurzweil's award-winning K2600 synthesizer. The KSP8 extends the arsenal of effect algorithms from KDFX, adding newly-developed surround reverbs and many more stereo and mono algorithms. The architecture has enough flexibility and power to process up to 8 channels of audio simultaneously, in mono, stereo, and surround combinations. Unlike other high-end effects systems whose DSP resources are fixed to a small number of processing engines, the 16 available processing units in the KSP8 may be freely shared among up to 8 effect buses. The sonic quality of the KSP8 is stunning; it has the best analog audio specifications in the industry, featuring unique output circuitry (patent-pending). The power, flexibility, and sound of the KSP8 truly make it a must-have for professional and semi-pro studios, as well as for sound designers in search of exciting new timbres.
