The KDA50 might be the smallest member of the KDA family, but don’t let the compact size fool you. This is a full-bodied monitor with plenty of volume. This model possesses a custom designed 10" speaker that kicks out tremendous lows. With dual volume knobs, controlling the drum volume and aux input volume is a breeze. The amp's EQ features Low, Mid, and High configuration to give you the power to set your tone. The Line In (aux) jack allows you to plug in an MP3 player to play along with your favorite tracks and the Headphone jack lets you play on your own timetable.
