6.  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). 

7.   Next, experiment with the KM60 or KM100's graphic 
equalizer.  Begin by setting each of the seven sliders to their 
flat “0” center detented position.  Finally, move each slider 
in turn as you play your Keyboard.  For more information, 
see the “About Equalization” section on pages 9-10 of this 
manual.  Again, when you get a graphic equalization setting 
that complements your instrument and playing style, it’s a 
good idea to write it down for future use.

If you have followed all the steps above and are still experi-
encing difficulties, call Samson Technical Support (516-932-
1062) between 9 AM and 5 PM EST.

Setting Up and Using Your Hartke KM60 and 

KM100 Keyboard Amplifier

8. Your KM series amplifier features a AUX/CD input which you 
can use with a portable CD player, cassette, mini disk or MP3 
player to jam with pre-recorded tracks or learn a riff from a 
favorite tune. In fact, you can plug any line level signal into 
the AUX input including the signal from a keyboard or drum 
machine. Connect the CD player or other Line level device to 
the AUX Input using standard RCA cable. You will want to use 
the volume control on the CD player or other Line level device 
to set the balance between the track and your keyboard.  So, 
start with the volume control all the way down and slowly 
raise it until you reach a good balance with your keyboard

9. Test the headphone output by turning the Volume control 
to its  minimum (fully counterclockwise) position and then 
connect a standard stereo headphone to the rear panel 
Phones jack.  While playing your keyboard, 

slowly

 turn the 

Volume control up—you should hear sound from the head-
phones and none from the connected speaker.
