Overview
The Motion Sound KP-500SN is a stereo keyboard amplifier with two 250-Watt channels, each one having dedicated speakers that are directed at an angle to provide an enhanced stereo image.
The speakers include two 12″ Eminence Beta-12A woofers, and two 3.5″ ferro-cooled horns.
If the stereo image brought about by its angled form factor is not enough, the KP-500S comes with an onboard 3D expander for even wider stereo sounds.
It has multiple inputs including stereo and mic input, and it has DI out for plugging into a PA system.
