KX-80 Keyboard Amplifier
OWNER’S MANUAL
Congratulations!
You are now the proud owner of the Crate KX-100 keyboard amplifier. This versatile
and great sounding amp features a 15” Crate Custom woofer and two LeSon dome
tweeters housed in a ported tuned enclosure. Each of the four discrete channels has its
own level and reverb/effect control while one of the channels also has separate low and
high rotary EQ controls, switchable phantom power and a balanced low impedance mic
input jack. The Master section features a 5-band graphic equalizer, a balanced line out
jack with a level control, two effects loops and a jack for headphones.
Like all Crate products, your KX-100 is Musician Made in the U.S.A., using only the
best components. Extensive testing at the hands (and ears) of skilled technicians and
musicians insures you that this amplifier is the absolute best it can be.
In order to get the most out of your new amplifier, we strongly urge you to go over
the information contained in this manual before you begin playing.
And thank you for choosing

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.
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

or signal source causes the LED to flash.
19: Preamp Out jack provides a high impedance unbalanced
5: Reverb/Effects Send controls are used to set the amount of output for connecting the KX-100 to another amplifier or a tape
reverb, as well as the amount of signal sent to the Effects Send recorder. Simply run a cord from this jack to the input of the other
jack (#17) for each channel.
amplifier or the tape deck.
6: Phantom Power applies 15 volts to the Mic input jack (#1) 20: Power Amp In jack is used as a direct input to the power
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).
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.
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.
