LINE

OUT

and 

PHONES

jacks.

PHONES

jack.  

5. BAL CONTROL (BALANCE)

control adjusts the difference in level between the 

L

R

inputs

of the channel.  You can double the number of inputs on these channels by plug-
ging in two different 

MONO 

sources to the

BAL-

ANCE

control to bring them to equal levels. 

CHANNEL 3 FEATURES

control adjusts the volume of 

Channel 3

heard in the speaker, at the

LINE OUT

jacks and the

jack.    

10. TONE CONTROL

The 

TONE

control is used to shape the bass or treble sound of the input signal.

Start with the tone control center position where it does not affect the signal.  Then
as needed, turn to the Right to boost 

HIGH

frequencies or to the Left to boost

LOW

frequencies.  

CHANNEL 4 FEATURES

11. XLR MICROPHONE & 1/4” INPUT JACKS

The 

MIC

input is designed for balanced low impedance ( microphone ) input sig-

nals.  The Balanced input will reduce the common noise picked up on the micro-
phone cables.  The XLR connector is wired as per the industry standard; pin 1 is
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.

12. LO, MID, AND HI TONE CONTROLS

The 

LO, MID

and 

HI

tone controls are used to shape the bass, midrange, and

treble sound of the input signal.  It is suggested that the tone control settings
start in their center positions where they do not effect the signal.  Then, as needed,
turn the  turn to the right to boost, or turn to the left to cut.  To add crispness to
your sound, set the 

Lo 

to +10, 

Mid

to -10, 

Hi

to +10.  

13. LEVEL CONTROL

The 

LEVEL

control adjusts the volume of the channel heard in the speaker, at

the

MASTER SECTION FEATURES

LEVEL 

controls. The

MASTER control does not affect the 

LINE OUT

or 

PHONES

levels.

15. LINE OUT CONTROL

The 

LINE OUT

control adjusts the output level of the rear 

LINE OUT

jacks.

16. PHONES LEVEL CONTROL

The 

PHONES LEVEL

control adjusts the volume heard at the 

PHONES

jack.

17. PHONES JACK

The stereo

PHONES

jack is driven by high current headphone amps that will

drive any pair of headphones.

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.
