Setting Up and Using the KM200
WARNING: Hartke amplifiers can deliver very high power levels. Driven to full
power, they can damage connected loudspeakers, regardless of brand, size, or
configuration. Care should be taken not to strain connected loudspeakers as this
can cause permanent damage and will degrade the performance of the entire
system. If you see connected loudspeakers moving excessively, turn your sys
-
tem down immediately or use the equalization and/or compression controls to
reduce the amount of sub harmonic (extremely low frequency) signal.
KM200 Basic Operation
Setting up your Hartke KM200 Keyboard amplifier is a simple procedure which takes
only a few minutes:
1. Remove all packing materials (save them in case of need for future service) and
decide where the amplifier is to be physically placed. To avoid potential overheating
problems, be sure that the rear panel is unobstructed and that there is good ventila
-
tion around the entire unit.
2. Locate the included casters, which are packed separately in the shipping carton,
and follow the installation instructions outlined in Appendix A on page 15 of this
manual.
3. Next, connect the 3-pin AC plug into any grounded AC socket. Don’t turn the
amplifier on just yet, though.
4. Use standard music instrument cables to connect your keyboards and/or drum
machine s to the appropriate Input jack, or jacks, on the top panel. If you are using a
mono signal be sure to connect to the Left (Mono) input jack. If you want to connect
a microphone, connect a low impedance mic to the Channel 1 XLR mix input.
5. On the front panel of the KM200, set the main Volume control to “0” (fully coun-
terclockwise and set channel volume knobs to “5” (the twelve o’clock position). Set
channel 1 Bass and Treble knobs to their center “0” position. Finally, set the graphic
equalizer sliders to the middle 0dB position.
6. Press the front panel Power switch in order to turn on the amplifier.
7. Set the output of your keyboard to about 3/4’s the way up and then, while playing,
slowly turn the main Volume control up until the desired level is achieved. If you hear
distortion even at low amplifier Master volume settings, back off the output of your
Keyboard (or check for a faulty cable). The main Volume control also includes a con
-
venient ON/OFF for muting the KM200's internal amplifier.
