Dear Customer,
Welcome to the team of
ULTRATONE users and
thank you very much for
expressing your confidence in BEHRINGER
products by purchasing
this keyboard amp.
It is one of my most
pleasant tasks to write
this letter to you, because it is the culmination of many months
of hard work delivered
by our engineering team
to reach a very ambitious
goal: to present you with
a series of outstanding
keyboard amplifiers that
give you maximum flexibility and performance with their unique sound character and
broad range of functions.
The task to design the new ULTRATONE series certainly meant
a great deal of responsibility, which we assumed by focusing
on you, the discerning user and musician. It also meant a lot of
work and night shifts to accomplish this goal. But it was fun, too.
Developing a product usually brings a lot of people together, and
what a great feeling it is when everybody who participated in
such a project can be proud of what we’ve achieved.
It is our philosophy to share our joy with you, because you are
the most important member of the BEHRINGER team. With your
highly competent suggestions for new products you’ve greatly
contributed to shaping our company and making it successful. In
return, we guarantee you uncompromising quality as well as
excellent technical and audio properties at an extremely
favorable price. All of this will enable you to fully unfold your
creativity without being hampered by budget constraints.
We are often asked how we can produce such high-grade
devices at such unbelievably low prices. The answer is quite
simple: it’s you, our customers! Many satisfied customers means
large sales volumes enabling us to get better conditions of
purchase for components, etc. Isn’t it only fair to pass this benefit
back to you? Because we know that your success is our
success, too!
I would like to thank all people whose help on “Project
ULTRATONE” has made it all possible. Everybody has made
very personal contributions, starting from the designers of the

and please do not place the ULTRATONE on high temperature
devices such as radiators etc. to avoid overheating.
Uli Behringer
Blown fuses must be replaced by fuses of the same
“SPECIFICATIONS” for details.
The mains connection of the ULTRATONE is made by using the
enclosed mains cable and a standard IEC receptacle. It meets all
of the international safety certification requirements.
Please make sure that all units have a proper
ground connection. For your own safety, never
remove or disable the ground conductor from the
unit or of the AC power cord.
Pressing the SHAPE button will add the Shape effect to
the main signal. The Shape function on your ULTRATONE
provides a revolutionary type of filter that you can use to
modify your keyboard sound (K3000FX and K1800FX only).
1.1.3 Online registration
Please do remember to register your new BEHRINGER equipment
right after your purchase by visiting

Registering your purchase and equipment with us helps us
process your repair claims quicker and more efficiently.
Use the POWER switch to switch the ULTRATONE on or
off. You should always make sure that the POWER switch
is in the “Off” position when initially connecting the unit to
the mains.
To disconnect the unit from the mains, pull out the main
cord plug. When installing the product, ensure that the plug
is easily accessible.
Thank you for your cooperation!
MAINS CONNECTION. Use the power cord supplied with
the unit to connect it to the mains.
High volume levels can damage your hearing or your
headphones. Please turn down the VOLUME control
to zero (all the way to the left) before you power up
the amp. Always make sure you use appropriate
volume levels.
connecting the unit to the mains, make sure that the voltage
setting matches your local voltage. A blown fuse should
only be replaced by a fuse of the same type and rating. On
some units, the fuse holder can be switched to one of two
positions, i.e. 230 V and 120 V. When operating the unit
outside Europe at 120 V, a higher fuse rating is required.
The LEVEL controls adjust the signal level of channels 1 - 4
(K900FX and K450FX: channels 1 - 3).
The GROUND LIFT switch disconnects (switch pressed)
the ground connection at the LINE OUT output to effectively
eliminate hum noise resulting from ground loops (K3000FX
and K1800FX only).
The four FX controls adjust the channel 1 - 4 signal level at
the input of the integrated effects processor (K900FX and
K450FX: three controls for channels 1 - 3).
The channel 4 signal (K3000FX and K1800FX only) is
normally routed just to the PHONES output without effects.
This way you can practice without being heard, or you
can connect a metronome that you need on headphones
but not on speakers. By pressing the TO MAIN button the
signal will be additionally routed to the speakers without
By pressing the TO LINE OUT button the channel 4 signal
will be additionally routed to the LINE OUT output without
effects (K3000FX and K1800FX only).
If you press both the TO MAIN and TO LINE button,
channel 4 will be equal to channels 1 - 3. The signal
will be routed to the speakers and the LINE OUT
output including effects.
The ULTRATONE is equipped with a 7-band graphic
equalizer (K900FX and K450FX: 5-band graphic equalizer).
Use the EQ to adapt the sound to the room acoustics.
Press the FBQ switch to activate the FBQ Feedback
Detection System. The frequencies causing feedback are
shown by the brightly lit fader LEDs. Simply lower the level
of the respective frequency range until feedback
disappears and the LED goes out.
The FX display shows the currently selected preset. The SIG
LED lights up when the effects processor receives an input
signal. When the CLIP LED lights up please reduce the effects
input signal by using the respective FX control(s)
Turn the FX control to select an effects preset (preset
number starts flashing). Push the control briefly to confirm
your selection.
The LEVEL control in the master section is used to adjust
the main output volume.
Please note: Merely switching the unit off does not
mean that it is fully disconnected from the mains.
When not using the unit for prolonged periods of
time, please unplug the unit’s power cord from the
power outlet.
Use the balanced LINE OUT XLR connectors to feed the audio
signal from your ULTRATONE to a mixing console (K3000FX
and K1800FX only). The LINE OUT signal is post-EQ.
These are the LINE OUT outputs on 1/4" TS connectors
(K900FX and K450FX: one 1/4" TS connector).
Both XLR and 1/4" TS LINE OUT connectors can be
used simultaneously.
For stereo operation the ULTRATONE features a STEREO
LINK facility. You can connect the OUT of the ULTRATONE
to the LINK IN of another keyboard amp that serves as
slave to achieve true stereo sound. When using the
ULTRATONE as slave, connect the LINK OUT of the master
amp to the IN (K3000FX and K1800FX only).
The SUB OUT connector provides the line-level mono
subwoofer signal for connection to the input of a power
amp or active subwoofer.
Connect your footswitch to the FOOT SW jack, so as to
activate/deactivate the effects processor.
Use the CD IN (K900FX and K450FX: AUX IN) connectors
to connect the output of your CD player, tape deck, CD or
MD walkman. This way you can play along to music or
keyboard tutorial CDs.
These are the LINE inputs for channels 1 - 4 on 1/4" TS
connectors. For mono input signals please use the
L (MONO) connector.
Channel 1 is equipped with an additional XLR MIC input. Due
to internal +15 V phantom power you can even use condenser
microphones. Both XLR and 1/4" TS connectors can be used
simultaneously. In this case the LEVEL control of channel 1
adjusts both the level of the LINE and MIC signal.
Turn the FX RET control to add the effect signal to the main

Fig. 3.1 shows how to connect your keyboard, a drum machine and
a microphone to the ULTRATONE. Additionally a CD player is connected
to the AUX IN input to feed in a playback. With the footswitch you can
activate/deactivate the internal effects processor.
Fig. 3.2 shows a recommended setup for amplifying the sound
of your ULTRATONE using a sound reinforcement system of
any size. This way, you can also use your amp for playing live or
for rehearsals with your band.
The ULTRATONE features 1/4" connectors on inputs and outputs
plus additional balanced XLR connectors for channel 1 input and
Line Out outputs (K3000FX and K1800FX). More detailed
