Congratulations on purchasing the Hartke KM200 stereo mixing Keyboard Amplifier! The KM200 is the
perfect solution for just about any keyboard player who needs a flexible mix /monitor system to handle
a sophisticated instrument rig, and who demands a high quality amplifier that faithfully reproduces the
sound, nuances, and soul, of their performance. The KM200 achieved this superior goal by delivering a
solid 200 watts of power, driving a classic Hartke 15” aluminum cone low frequency drive unit, working
with a 1” titanium compression driver, enclosed in an innovative kickback cabinet, giving you a powerful
full-range 2-way professional monitoring system. For players with multiple keyboards and sound modules,
an additional mixer isn’t needed because the KM200 has one built-in. The mixer features a stereo input with
2-band EQ and Mic input, as well as three additional stereo inputs, giving you a total of 4-stereo channels,
plus a stereo Aux in, advanced signal routing and special headphone monitoring capabilities. In fact, you’ll
have independent control of Local, PA, and headphone monitor mixes. The KM200 also features a powerful
7-band Graphic Equalizer allowing you to set a customized frequency response contour that’s perfect for
your sound and helps you hear yourself better on stage. The convenient casters make the KM200 easy to
transport and the solid construction makes it a reliable performer from night-to-night and venue-to-venue.
