Delivers deep, dynamic, lush soundscapes to live performances.
The Motion Sound KP-408S Stereo Combo Keyboard Amplifier meets this challenge head on. The KP-408S 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-408S, with its 200 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-408S – 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 Ultra-light MDF to keep the bulk to a minimum.
Three Dimensional Sound
The KP-408S 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.
