KX-100 Keyboard Amplifier
1: Mic input jack will accept a low impedance balanced input,
such as a microphone, and may be used in conjunction with the
Line Input (#2).
2: Line input also provides Channel 1 with a 0dB balanced
input jack. It is suitable for a signal source from synthesizers.
3: Level controls set the gain for each channel independently.
4: Peak Indicator LEDs light when the corresponding input
stages of the each channel are within 10dB of clipping. Adjust
each Level control (#3) until a strong signal from the instrument
or signal source causes the LED to flash.
5: Reverb/Effects Send controls are used to set the amount of
reverb, as well as the amount of signal sent to the Effects Send
jack (#17) for each channel.
6: Phantom Power applies 15 volts to the Mic input jack (#1)
when this switch is pressed in.
7: Low control increases or decreases the bass response of
channel 1.
8: High control increases or decreases the treble response for
channel 1.
9: Input jacks for Channels 2, 3 and 4 accept standard 1/4"
phone jacks, and are suitable for a line level source such as a
signal from synthesizers.
10: Master EQ has five bands and enables you to shape the
tonality of the KX-100 to suit room acoustics. Frequencies from
100Hz to 10kHz may be boosted by moving the sliders up or cut
by moving them down.
11: Reverb Return acts as the reverb master level control and
works with each channel's Reverb/Effects Send control (#5).
12: Master Level controls the total output level of the KX-100.
13: Effects Return control is a master volume for the Effects
Loop (#17 and 18) with which you can increase or decrease the
amount of effect desired. This control works with each channel's
Reverb/Effects Send control (#5).
14: Balanced Line Out/Headphones Level adjusts the level
for both the Balanced Line Out and Headphones jack and is
independent of the Master volume.
15: Power Indicator LED will be lit when the unit is turned on.
16: Power Switch turns the AC power on and off.
17: Effects Loop Send jack, when used in conjunction with the
Return jack (#18), provides a pre-EQ effects loop. The pre-EQ
circuitry reduces the unwanted noise associated with most
external effects devices. This output can be connected to the line
input of your external effects device.
18: Effects Loop Return jack can be connected to the line out-
put of your external effects device.
19: Preamp Out jack provides a high impedance unbalanced
output for connecting the KX-100 to another amplifier or a tape
recorder. Simply run a cord from this jack to the input of the other
amplifier or the tape deck.
20: Power Amp In jack is used as a direct input to the power
amp. Plugging into this jack disconnects the direct (normal) con-
nection between the preamp and the power amp. This jack may
be used with the Preamp Out jack (#19) as an effects loop.
21: Balanced Line Out jack is a low impedance balanced out-
put for connection to an external amplifier or mixer with balanced
inputs.
22: Headphones jack allows the use of stereo headphones.
Connecting headphones here does not disconnect the internal
speakers. For private listening, turn down the Master level con-
trol (#12).
23: Power Cord (rear panel, not shown): Your KX-100 is
equipped with a heavy-duty grounded three-wire power cord. Be
sure this cord is properly plugged into a safely wired grounded
120 volt, 60Hz AC power outlet before use. (If your KX-100 was
purchased outside the United States, refer to the rear panel for
power ratings.) For your safety, never attempt to defeat the
ground connection on this cord.
