KX-50 Keyboard Amplifier
Congratulations!
You are now the proud owner of the Crate KX-50 keyboard amplifier. This compact
powerhouse features a 12” Crate Custom woofer and Piezo tweeter housed in a ported
tuned enclosure. Each of its two input jacks has its own level control so you can mix your
keyboard with another instrument, a tape deck or a Hi-Z vocal mic. The amplifier features
three rotary EQ controls and a Master Reverb and Volume control. The Insert/Line Out
jack allows you to connect external effects the amp or to run a signal to a recorder, mix-
ing board or house PA. A Headphone jack allows for private practice sessions.
Like all Crate products, your KX-50 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
OWNER’S MANUAL
KX-50 Keyboard Amplifier
1: INST. 1 INPUT JACK: Plug any low to line level signal (key-
board, synthesizer/sampler, drum machine, tape deck, etc.) here.
Use the Mixer Level 1 control (#3) to adjust the signal strength at this
input.
2: INST. 2 INPUT JACK: Plug any low to line level signal (key-
board, synthesizer/sampler, drum machine, tape deck, etc.) here.
Use the Mixer Level 2 control (#4) to adjust the signal strength at this
input.
3: MIXER LEVEL 1 CONTROL: Adjust the level of the Instrument
1 signal with this control. Low output instruments may need a setting
in the 5-10 range while instruments with “hotter” outputs may need a
setting between 0 and 5. The best setting will cause the peak indi-
cator (#5) to flash occasionally while playing. Too low a setting may
increase background noise while too high a setting may cause
harshness or distortion.
4: MIXER LEVEL 2 CONTROL: Adjust the level of the Instrument
2 signal with this control. Low output instruments may need a setting
in the 5-10 range while instruments with “hotter” outputs may need a
setting between 0 and 5. The best setting will cause the peak indi-
cator (#5) to flash occasionally while playing. Too low a setting may
increase background noise while too high a setting may cause
harshness or distortion.
5: PEAK INDICATOR LED: This LED will light when the input lev-
els are high enough to cause undesirable clipping and distortion.
When levels are too high this LED may stay on continuously. If this
happens, reduce the Level controls until the LED flashes occasion-
ally at peak signals.
6: LOW CONTROL: Adjust the output level of the low tones with
this control. The center position is “flat” (no boost or cut). Turning the
control to the left reduces the output level of the low tones, turning it
to the right boosts their level. This control allows a 26dB range of
boost or cut at 100Hz.
7: MID CONTROL: Adjust the output level of the midrange tones
with this control. The center position is “flat” (no boost or cut). Turning
the control to the left reduces the output level of the midrange tones,
turning it to the right boosts their level. This control allows a 24dB
range of boost or cut at 700Hz.
8: HIGH CONTROL: Adjust the output level of the high tones with
this control. The center position is “flat” (no boost or cut). Turning the
control to the left reduces the output level of the high tones, turning it
to the right boosts their level. This control allows a 26dB range of
boost or cut at 8kHz.
9: REVERB CONTROL: Adjust the amount of reverberation effect
with this control. At the extreme left (0) position the signal is “dry” - no
reverb effect is added. As the control is rotated to the right the
amount of reverb increases, giving a “concert hall” fullness to the
sound. The reverb control affects both input channels.
10: MASTER VOLUME CONTROL: Use this control to adjust the
output level of the amplifier, as well as the signal level at the Line Out
and Headphone jacks (#12 and 13). At the extreme left (0) position
there will be no output; rotating the control to the right increases the
output power.
11: LIMIT: When a power amplifier reaches maximum output levels
it may begin to “clip” its output signal which generates potentially
speaker-damaging distortion. The KX-50 has a special APM
(Automatic Power Maximizer) limiting circuit which helps minimize
this problem by monitoring the power amplifier’s output signal, keep-
ing it below clipping. This feature insures you that the sound from
your amplifier remains clean and pure even at full power. The APM
indicator will only light when the amplifier is near clipping: flashing at
peak playing levels is acceptable, however if the light remains on
constantly, reduce the Master Volume until the light flashes.
12: INSERT/LINE OUT JACK: This jack provides you with an
effects loop into the KX-50’s power amp. The jack requires a 1/4”
stereo phone plug with two shielded cables in a “Y” type configura-
tion. The ring is “LINE OUT,” the tip is “LINE IN” and the sleeve is a
common ground. This jack can also be used as a “line out” tap by
inserting a 1/4” mono phone plug half way into the jack. This does not
interrupt the signal going to the power amp.
13: HEADPHONES JACK: For private practice sessions plug a pair
of stereo headphones into this jack. The KX-50’s internal speaker is
disconnected when the headphone jack is used.
14: ON INDICATOR:This indicator will be lit when the amplifier is on.
15: POWER SWITCH: This switch turns the amplifier on in the right
position and off in the left position.
16: POWER CORD: (Rear panel, not shown) This heavy-duty
grounded three-wire power cord. is to be plugged into ONLY a safe-
ly-wired, grounded 120 volt, 60 cycle AC power outlet. DO NOT
attempt to defeat the ground connection on this cord. If your KX-50
was purchased outside of the United States, refer to the rear panel
its power requirements and follow the above guidelines.
The KX-50 is covered with a durable black Tolex material: wipe it clean with a lint-free cloth. Never spray
cleaning agents onto the cabinet. Avoid abrasive cleansers which would damage the finish.
El KX-50 esta cubierto con un material durable Tolex: limpielo con una toalla seca. Nunca rocie el gabinete con sustancias
limpiadoras. Evite usar materiales abrasivos con los cuales pueda danar el acabado.
Le KX-50 est couvert avec «Tolex» un recêtement noir et durable. Essuyez cette matière avec une toile propre et sans charpie. Ne
pulvérisez jamais les agents de nettoyage sur l'appareil. Evitez les nettoyeurs abrasifs qui peuvent endommager le «Tolex.»
