The Perfect Partner for Live Performance

Today’s modern keyboard sounds – whether hardware or software based – offer a wonderful richness and depth of sound that has never before been available. The challenge for performing musicians is to be able to properly bring all that wonderful sound to life in a live performance situation without having to haul around a ton of sound reinforcement equipment.


The Motion Sound KP-500S Stereo Combo Keyboard Amplifier meets this challenge head on. The KP-500S delivers the same deep, dynamic, lush soundscape to live performances that can be heard through a good set of studio monitors or headphones.


Powerful and Portable, Clean and Compact

The KP-500S, with its 250 watts (RMS) of clean power per channel, is designed to reproduce any modern keyboard sound with the level of clarity and punch needed to bring inspiration out of the studio and into every live performance.  In addition, the KP-500S – with its compact all-in-one combo design – makes setup quick, easy and convenient. It has plenty of inputs and outputs to satisfy the requirements for any professional performance situation, and the cabinet is built out of lightweight MDF to keep the bulk to a minimum.


Three Dimensional Sound

The KP-500S has a V-shaped angled cabinet design that dramatically widens the stereo image far beyond what you’d expect from such a compact cabinet. Plus, the stereo field can be further enhanced by taking advantage of Motion Sound's proprietary 3D Expander to turn the stereo sound into a real 3D image, bringing all sorts of motion and magic to your live sound.
