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 weve achieved.
It is our philosophy to share our joy with you, because you are the most important member of the BEHRINGER

1. INTRODUCTION
Lets be honest: as a keyboard player youre one of those musicians who carry around so much equipment
that you never know how to get things connected properly, arent you? And probably the other guys in your
band do keep complaining about your alone using half of the channels on the mixing console, dont they?
We knew that. And thats why we designed the KX1200. Not only is this all-purpose amplifier the ideal tool to
amplify your keyboards, but it also forms a perfect base for building a small-scale P.A. system. But first things
firstꢀ
BEHRINGER is an audio engineering company that has been successfully developing professional products
for studio and live applications for many years now. Our range of products includes microphones and a variety
of 19" devices (compressors, enhancers, gates, tube processors, headphone amps, digital effects devices, DI
boxes, etc.) as well as monitoring and P.A. speakers plus professional live and recording consoles. We have
bundled our entire technical know-how and experience in your KX1200.
What are the features that a keyboard amplifier should have? Well, lets take a look at your gear. You surely
have a couple of keyboard instruments and expanders, which youd like to connect to one and the same amp
at the same time. No problem with the KX1200. After all, it features four separate channels. Probably, you
also have an effects device to give that beloved organ sound the finishing touch. Here, too, your KX1200 is well
equipped in that it features a separate effects path, i.e. each of the four channels can have its own effect
intensity.
What about your voice? Wouldnt you like to sing at least some of the songs you composed? We knew you
would. Thats why we equipped the KX1200 with an input for your microphone.
Well, and finally your drum computer and CD player loaded with sampling CDs: simply connect them to the
tape input. And your headphones? Well, no need to askꢀ
Now weve come full circle: last time you rehearsed with your band, you occupied six channels plus effect path
on the console; now you only need one amp occupying just one console channel. Your co-musicians will be
grateful for that! And by the way: basically, the guitar or bass player in your band could also use your KX1200,
as long as you dont need all four channels for your keyboards equipment.
No later than now it becomes clear that your KX1200 is anything but a conventional keyboard amp, doesnt it?

KEYBOARDAMP/PASYSTEM KX1200
1.1 Before you begin
Your KX1200 was carefully packed in the factory and the packaging is 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, which may have occurred during transit.
+
If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the
shipping company immediately, otherwise claims for damage or replacement may not be
granted. Shipping claims must be made by the consignee.
Be sure that there is enough air space around the unit for cooling and please do not place the KX1200 on
high-temperature devices such as power amps or radiators, etc. to avoid overheating.
+
Before you connect the KX1200 to the mains, please make sure that your local voltage matches
the voltage required by the unit:
The fuse holder on the female mains connector has 3 triangular markings, with two of these triangles opposing
each other. The KX1200 is set to the operating voltage printed next to these markers and can be set to another
voltage by turning the fuse holder by 180°. CAUTION: This instruction does not apply to export models
exclusively designed, e.g. for 115-V operation!
Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable
safety standards.
+
Please note that all units must be grounded properly. For your own safety, you should never
remove any ground connectors from electrical devices or power cords or render them
inoperative.
+
Please note that extreme output volumes can lead to permanent hearing damage. Turn down
the VOLUME control before you switch on the unit. Be sure to use appropriate volume levels.
1.2 Control elements
1.2.1 Front panel
Your BEHRINGER KX1200 has four identical channels, and each of these channels has two controls. Since all
channels are identical, the following descriptions refer to one of them only.
Fig. 1.1: KX1200 front panel
1
2
Use the VOLUME control to adjust the channel volume.
The FX/MON control determines the channels effect intensity or monitor volume.
+
Basically, the VOLUME controls of channels 1 through 4 work like a gain control, i.e. you can
use these channels to connect any type of conventional keyboard or string instrument, and
adapt the input sensitivity with the VOLUME controls.
3
4
5
The BASS control allows you to boost/cut the bass frequencies.
The LOW MID control governs the low midrange frequencies.
Use the HIGH MID control to adjust the upper midrange frequencies.
6

The HIGH control allows you to boost/cut the treble frequency range.
Use the MASTER control to determine the KX1200s overall volume level.
The stereo 1/4" HEADPHONES jack allows you to monitor the amps audio signal with a pair of
commercially available headphones. Connecting the headphones will mute the built-in speakers.
9
Use the POWER switch to switch your KX1200 on or off. The POWER LED located between the HIGH
and MASTER controls lights up when the unit is switched on.

FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the voltage
indicated on the unit, before you attempt to connect and operate the KX1200. Blown fuses may only be
replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder in two
different positions, in order to switch over from 230-V to 115-V operation, and vice versa. Please note
that for 115-V operation outside Europe, you need to use a fuse of a higher rating.
11
12
Use the enclosed power cord to connect the unit to the mains.
SERIAL NUMBER. Please take the time to fill out and return the warranty card within 14 days after the
date of purchase, so as to be entitled to benefit from our extended warranty. Or use our online registration
13
The MAIN OUT allows you to connect the KX1200 to an external amplifier.
+
Use the MAIN OUT to connect the KX1200 to a mixing console, unless the console has balanced
inputs. In this case, you should always use the D.I. output of your KX1200.
14
15
16
LINE 1 - 4: These 1/4" TRS inputs are used to connect line-level instruments.
The balanced D.I. OUT (XLR) allows you to connect the KX1200 to the input of a mixing console.
The TAPE OUT connector (RCA) supplies the audio signal of your KX1200, for example to send it to a
recording machine.
17
The TAPE IN connector (RCA) allows you to connect an external signal source such as a drum computer
or other machine providing audio playbacks.
18
Connect the FX RETURN to the output of an external effects device.
+
19
The FX RETURN can also be used to feed in the output signal from an external amplifier.
Connect the FX/MON OUT to the input of an external effects device.
+
The FX/MON OUT can also be used as a monitor output. Use the FX/MON controls 1 through 4
to adjust the volume levels of the connected instruments as part of the monitor mix.
20
The MIC 1 input (XLR) allows you to connect a microphone.
+
Use channel 1 to connect either a microphone or a line-level signal, but never both at the
same time!

2. WIRING EXAMPLES
2.1 Standard keyboard set-up with external drum computer and effects device
The standard set-up allows you to connect your entire keyboard equipment. Instead of the drum computer you
could also use some sort of playback provided, for example, by a tape deck or CD player.
Fig. 2.1: Standard set-up
2.2 Expanded P.A. set-up with four instruments, microphone and connection to a
recording console
For small gigs or rehearsals with a band we recommend using the wiring scheme below, which expands the
standard set-up described above.
+
+
Please remember to connect either a microphone or a line-level signal to channel 1, but never
both at the same time!
When you wish to connect an electric guitar, we recommend that you process the signal
before with a guitar preamp that features a speaker simulation circuit. Otherwise, the guitar
sound will suffer from excess presence in the treble range. The outputs of guitar preamps are
usually equipped with a speaker simulation circuit.

3. AUDIO CONNECTIONS
The 1/4" jack inputs/outputs of your BEHRINGER KX1200 are on balanced mono jacks except for the
LINE IN-connectors (TRS) and the stereo headphones connector. The DIRECT OUT and microphone input are
on balanced XLR connectors. The tape inputs/outputs are on cinch connectors.
+
Please ensure that only qualified personnel install and operate the KX1200. During installation
and operation the user must have sufficient electrical contact to earth, otherwise electrostatic
charges might affect the operation of the unit.
