KXR 100 Owner’s Manual
Congratulations on your purchase of the Fender KXR 100
keyboard amplifier. The Fender KXR 100 is the most recent
effort in state of the art keyboard amplifier technology, and is
a member of the FENDER KXR series. The design execution of
the KXR 100 was carried out with the aid of some of today’s
best musicians, and represents years of thought and
consideration in determining features and specifications.
The KXR 100 is actually much more than a keyboard amp.
With its heavy-duty Fender Special Design speaker and dual
piezo-electric horn, it could actually be classified as a
self-contained portable PA. system, suitable for almost any
musical instrument requiring full-range reinforcement, for
example electronic keyboards, acoustic/electric guitar,
electric violin, and voice. Compact packaging and
medium-level output power make the KXR 100 the perfect
full-range instrument amplifier for rehearsal, studio, or small
club performances.
The preamp section of the KXR 100 features three
independent channels, a 4 band master EQ, and master
reverb and volume controls. Each channel features a single
1/4 inch input jack and volume control. In addition to the
1/4 inch input jack, channel #1 features an XLR input jack for
the connection of a low impedance microphone. The
EFFECTS SEND and EFFECTS RETURN jacks can be used with
a wide variety of effects devices, or as patch points for
slaving multiple amps together. The EFFECTS SEND can also
be used to connect your KXR 100 directly to a recording
console or sound reinforcement mixer.
The HEADPHONE jack automatically mutes the speaker while
driving stereo or mono headphones for private practice
sessions. The HEADPHONE jack can also be used as another
line level output. RECORD OUT RCA jacks are provided to
deliver a line level preamp signal for tape recording
convenience.
The rugged 80 watt power amplifier was designed to give
years of reliable service under all conditions and is equipped
with a unique implementation of our exclusive
DELTACOMP™ adaptive compression system. When
DELTACOMP™ engages, it is practically impossible to cause
the power amplifier to clip (distort). With DELTACOMP™,
apparent compressor release time is kept short, yet waveform
distortion is kept to a minimum at low frequencies.
The selection of a Fender amplifier will reward you with years
of quality music in a wide range of sonic possibilities. This
manual is designed to familiarize you with the features and
functions of your KXR 100 amplifier. Read this manual
carefully so you will benefit from these features as soon as
you start using your new Fender amplifier.
The built-in quality of a Fender amplifier is the result of over
four decades of dedication in the combined skills of the
Fender design team. That’s why we proudly say, FENDER..
The Sound That Creates Legends.
KXR 100 Front Panel Functions
A. Channel 1 Input (XLR)- A high sensitivity, XLR style
connector designed for use with microphones. This balanced
input can handle as much as 1V R.M.S.
B. Channel 1 Input (Phone)- Plug-in connection for
instruments. This balanced input can handle as much as 8V
R.M.S.
C. Channel 1 Volume- This control adjusts the preamplifier
gain of channel 1. It works in conjunction with the Master
Volume control (item 1) to set the overall loudness of the
amplifier for channel 1 only. Being a true “gain” control, it
allows for the use of a variety of microphones, keyboards or
other instruments with differing output signal levels. Lowlevel instruments generally require a higher Channel Volume
setting while “hotter” keyboards will require a lower setting.
D. Channels 2 and 3 - These channels are provided for two
additional instruments. The inputs and volume controls
operate in the same manner as items B and C in Channel 1.
These channels are muted when nothing is plugged into their
inputs, and thus will contribute no additional residual noise
to the amplifier output when left unused. All three channels
may be used simultaneously, however Channel 1 should be
used first if only one input is needed.
E. Equalizer- The equalizer allows precise adjustments of the
tonal characteristics of the amplifier. Each control provides a
12 dB boost or cut to bands of frequencies centered about
100, 338,1588, and 4000 Hz.
F. Reverb control- This control adjusts the amount of reverb to
be mixed with the dry signal. The input to the reverb circuitry
is the sum of channels 1, 2 and 3.
G. Effects Send jack- This jack provides an unbalanced
output signal from the preamp. This output can be used with
the Effects Return jack (item H) as a patch point for mono
effects devices. The Effects Send is connected to the input of
the effect (digital delay or other effects device) and the output
of the effect is connected to the Effects Return jack (item H).
The Effects Send can also be used to provide a signal to a
recording or sound reinforcement mixer. In addition, this
output can be used to drive another KXR 100 as a slave amp.
This is done by connecting a standard guitar cord from the
Effects Send jack of the master amp to the Effects Return jack
of the slave amp.
H. Effects Return jack- This balanced jack inputs signal to the
Master Volume control, which drives the power amp section.
It automatically disconnects the preamp when used. This jack
is useful with the effects loop feature, or when using the KXR
100 as a slave amp.
1. Master Volume control- This control adjusts the level of the
signal coming out of the preamplifier section. This control is
used in conjunction with the Channel Volume controls to set
the overall sound level of the amplifier. In order to maximize
headroom and minimize noise, instruments with low-level
output will require a high Channel Volume setting and a low
Master Volume setting, while other instruments may require a
lower Channel Volume and higher Master Volume setting. It
is recommended that the Master Volume control be set as
high as possible for maximum DELTACOMP’ compressor
range.
J. Record Out jack- Two RCA style jacks provide an
unbalanced, mono signal for recording. This signal is derived
from the preamp and is at line level, similar to that of the
Effects Send jack. The level is not affected by the Master
Volume Control.
K. Headphone jack- This jack allows the use of stereo
headphones for private listening. When this jack is used, the
internal speaker is disconnected. WARNING: BE CAREFUL
WHEN USING HEADPHONES, AS EXCESSIVE VOLUME
WILL DAMAGE YOUR HEARING.
L. Power Indicator- When this LED is illuminated, the KXR
100 is receiving power.
M. Power Switch- This switch turns the KXR 100 or Off.
When the switch is off, the amplifier is completely shut down.
KXR 100 Rear Panel Functions
NOTE: DO NOT BLOCK THE AIR FLOW TO THE REAR PANEL;
FOR EXAMPLE, BY BACKING THE AMPLIFIER UP AGAINST A
WALL. The rear panel is used to keep the output devices from
getting too hot.
POWER CORD - This amplifier is equipped with a grounding
type supply cord to reduce the possibility of shock hazard. Be
sure to connect it to a grounded AC receptacle. The line cord
should be connected to a suitable power source, in
accordance with the voltage and frequency as shown by the
power rating on the rear panel. DO NOT ALTER THE AC
(MAINS) PLUG.
WARNING: THIS EQUIPMENT MUST BE GROUNDED.
COVERING CARE- The exclusive vinyl covering on your
cabinet has been especially designed for years of lasting
beauty. A very light, soapy solution on a sponge may be used
to remove dirt and residue that may accumulate in the
texture. Be careful not to let any liquid come in contact with
the operating surfaces. UNPLUG THE POWER CORD BEFORE
CLEANING.
Troubleshooters Checklist
If the amp is set up but does not function, check the following items:
- Is the amp power cord plugged into an electrical outlet?
- Is there power at the outlet?
- Are all the control knobs turned up?
- Is the volume control on the instrument turned up?
- Is the instrument properly plugged into the amplifier?
(Eliminate any effect pedals and try another guitar cord.)
If, after checking all of the above, the system is still not performing correctly,
consult your FENDER Service Dealer.
