KB100 FRONT PANEL FEATURES
CHANNEL 1&2 FEATURES
1. L (M0NO) & R INPUT JACKS
These 1/4"INPUT jacks are designed for keyboards but will work with most any
inputs. Plug the stereo outputs from your keyboard into these jacks. Plugging
into the L(MONO) jack only will send that input to both Left and Right at the LINE
OUT and PHONES jacks.
2. CH 1 RCA INPUT JACKS
The Left and Right RCA inputs on Channel 1 are for connecting disc players,
MP3 players, tape decks, as well as keyboards with RCA connectors.
3. +12DB GAIN SWITCHES
For inputs with low level signals on CH1 and CH2, press "IN" the +12dB switches
to raise the level.
4. LEVEL CONTROL
The LEVEL controls adjust the volume of each channel heard through the speaker
at the LINE OUT jacks and the PHONES jack.
5. BAL CONTROL (BALANCE)
The BALANCE control adjusts the difference in level between the L and 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 L and R inputs and adjusting the BAL-
ANCE control to bring them to equal levels.
CHANNEL 3 FEATURES
6. CH 3 INPUT JACK
The CH 3 input jack is a high-impedance input designed for keyboard, line level,
an unbalanced mic and instruments such as a guitar or bass.
7. INST (INSTRUMENT LEVEL) SWITCH
The INST switch increases the level.
8. MID SWITCH
The MID switch provides additional tone shaping for instruments by cutting mid
frequencies in the 500Hz range.
9. LEVEL CONTROL
The LEVEL control adjusts the volume of Channel 3 heard in the speaker, at the
LINE OUT jacks and the PHONES 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 LINE OUT jacks and the PHONES jack.
MASTER SECTION FEATURES
14. MASTER VOLUME
The overall speaker volume is controlled by the MASTER control. Turn up the
volume here before increasing the individual channel 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.
