FOREWORD
TABLE OF CONTENTS
Dear musician,
Congratulations and
thank you very much for
purchasing the KT108
BEHRINGER keyboard
amplifier.
The ULTRATONE KT108
is a truly versatile
keyboard amp that will be
loads of fun to use.
Had anybody told you a
few years ago that one
day you’d be able to buy
a keyboard amp with
authentic tube sound
simulation at such an
unbeatable price, you
would have probably
called him nuts.

But I wanted this amp to become reality, and now we’ve actually
made it! With our ULTRATONE KT108 you can now follow in the
footsteps of all the big keyboard legends. Simply unpack it, plug
it in and you’re ready to go! The ULTRATONE KT108 gives you
everything your heart desires.
What we really wanted was to give you a truly high-quality
keyboard amp. Believe me: With all those years of experience
under our belt, we know what an amp needs to put up with. No
matter how often you practice or how many sessions you have
with your friends: when it comes to quality and sound, your
ULTRATONE KT108 will give you years and years of pure
enjoyment.
Now, just in case you’re wondering how we can offer such a
high-quality keyboard amp at such an unbelievably low price...
the answer is totally simple: it’s thanks to you! Many satisfied
customers means large volumes of units sold. Many units sold
means better purchase prices for components, and so on. So, we
just passed this price advantage on to you. It‘s only fair, isn’t it?
Enough talk now. One day, when you‘re one of those legendary
keyboard players yourself, we hope you‘ll say that your first
real keyboard amp was a BEHRINGER. In that case, you have
made a dream come true for us, too.
We wish you lots of success!
Thank you very much,
1. INTRODUCTION
Congratulations! By purchasing the KT108, you have obtained
a first-class keyboard amplifier that offers you the authentic
tube sound simulation in an amazingly compact housing. The
two instrument inputs and the additional CD player input make
the ULTRATONE KT108 a truly flexible practice amp that will be
tons of fun to use, no matter where or when you use it.
VTC Virtual Tube Circuitry
The VTC Virtual Tube Circuitry was specially developed to
lend the keyboard sound the unique character of classic tube
amps.
Jam it up!
With its CD player input, your KT108 is the ultimate practice
amp, because it couldn’t be easier to play along to your favorite
music. If you don’t want anybody listening to what you’re playing,
or simply wish to avoid disturbing the neighbors, just use your
headphones. The BEHRINGER HPS3000 is ideal just for that.
A companion for life!
The electronic components in your ULTRATONE KT108 have
been built into a robust metal enclosure for maximum protection.
The cabinet is made of high-grade wood covered with durable
vinyl. The KT108 will never let you down, even when the going
gets tough.
+
Please read the manual carefully and keep it around
for future reference.

ATTENTION!

High volume levels can damage your hearing or your
headphones. Please turn 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.
1. INTRODUCTION
ULTRATONE KT108
1.1 Before you get started
1.1.1 Shipment
Your KT108 was carefully packed at the factory, and the
packaging was designed to protect the unit from rough handling.
Nevertheless, we recommend that you carefully examine the
packaging and its contents for any signs of physical damage
that may have occurred during transit.
+
+
+
+
If the unit is damaged, please do NOT return it to
BEHRINGER. Instead, notify your dealer and the
shipping company immediately. Otherwise, claims
for damage or replacement may not be honored.
Always use the original packing carton to prevent
damage during storage or transport.
Make sure that no children are left unsupervised
with the KT108 or its packaging.
Please ensure proper disposal of all packing
materials.
1.1.2 Initial operation
Be sure that there is enough space around the unit for cooling.
To avoid overheating, please do not place the ULTRATONE near
radiators and other equipment emanating heat.
+
Please keep in mind that all the equipment has to
be grounded at all times. For your own protection,
never change or disable the grounding on your
equipment or on the cables! The unit shall always
be connected to the mains socket outlet with a
protective earthing connection.
Fig. 2.1: Example of a setup using the ULTRATONE KT108
Fig. 2.2 shows a recommended setup for amplifying the vintage
sound of your KT108 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.

2. WIRING TIPS
Figures 2.1 and 2.2 show you how to connect your keyboard
to the amplifier.
If you want to use an effects unit (for example, the BEHRINGER
X V-AMP) to experiment with some out-of-the-ordinary sounds,
you can connect your keyboard directly to the input of the effects
processor. Then, connect a second cable from the effects output
to the input on your keyboard amp.
+
The built-in loudspeaker is disabled automatically
when you plug in the headphones
.

3. CONTROL ELEMENTS
Fig. 3.1: Control elements on the front panel
Connect your keyboard to the INST. 1 INPUT connector,
using a standard instrument cable equipped with 1/4" TS
connectors.
The second instrument input (INST. 2 INPUT) can of course
be used to connect a second keyboard or a drum computer.
+
Please note: The POWER switch does not disconnect
the unit from the mains. Unplug the power cord
when you don’t want to use the unit for some time.
SERIAL NUMBER.
The volume of both instrument channels can be adjusted
using the INST. 1 VOL and INST. 2 VOL control.
Use the CD INPUT 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.
This connector is a 1/4" TRS jack. If your CD player is
equipped with cinch outputs, you’ll need an adapter cable,
which you can buy at your local music shop. Illustration 4.3
in chapter 4. “AUDIO CONNECTIONS” shows you what
kind of adapter to buy. You can also use a mono cable (fig.
4.4). This will not damage your CD player or keyboard amp.
Fig.: 3.2 Rear panel: serial number
The LOW control allows you to boost or cut the lowfrequency range.
With the MID control you can boost or cut the mid-range
frequencies.
The HIGH control adjusts the high-frequency range.
+
+
+
With all the settings the following applies: Adjusting
the tone settings on your KT108 lets you refine the
sound of your keyboard; for example, you can add
more depth to a bass sound, or you can bring out
the strings upfront by increasing the mids.
Sometimes more neutral settings are desired in
order to preserve the character of the original
sound.
The HEADPHONES jack is for headphones. When you
plug in your headphones, the built-in loudspeaker is muted.
The headphone signal can also be routed to a mixing
console or sound reinforcement system. Connect
the headphones output on your KT108 to the line
input (LINE IN) on the console (for example,
BEHRINGER EURORACK UB1222FX-PRO). Please use a
mono cable for this application.
Some headphones produce distortion if the volume
level is too high. Please cut back the volume control
until the distortion disappears.
Use the POWER switch to switch on your KT108. The
POWER switch should be set to “Off” before you connect
your keyboard amp to the mains.
