ground, pin 2 is positive and pin 3 is negative. The 1/4” jack is designed for key-
board and line level signals. Both of these inputs can be used at the same time.

18. THE 5 BAND GRAPHIC EQUALIZER
The 5 band graphic EQ is an excellent tool to fine tune the overall mix from your
KB100
. To use the 5 band Graphic, set all sliders to their center detent position.
When the sliders are in this position, they do not effect the audio signal. When a
slider is raised or lowered, it boosts and cuts the listed frequency. One setting that
can be used to enhance your sound is to cut the mid range (set 800 Hz slider to -
8) and raise the high and low frequencies as shown. This is a common “smile”
curve that gives a tight punchy sound with plenty of highs to cut through a crowd.
This EQ does not affect the
LINE OUT
or
PHONES
jacks.
19. POWER SWITCH
The power switch is to be utilized as the master ON/OFF switch. If the power
LED does not turn on, check the power cable and make sure it is properly con-
nected at the back of the amp. Also verify there is power at the wall receptacle.
If the amp does not power up after this is verified, contact customer service.
