1. INTRODUCTION
Lets be honest: as a keyboard p ayer youre one of those musicians who carry around so much equipment
that you never know how to get things connected proper y, arent you? And probab y the other guys in your
band do keep comp aining about your a one using ha f of the channe s on the mixing conso e, dont they?
We knew that. And thats why we designed the KX1200. Not on y is this a -purpose amp ifier the idea too to
amp ify your keyboards, but it a so forms a perfect base for bui ding a sma -sca e P.A. system. But first things
first
BEHRINGER is an audio engineering company that has been successfu y deve oping professiona products
for studio and ive app ications for many years now. Our range of products inc udes microphones and a variety
of 19" devices (compressors, enhancers, gates, tube processors, headphone amps, digita effects devices, DI
boxes, etc.) as we as monitoring and P.A. speakers p us professiona ive and recording conso es. We have
bund ed our entire technica know-how and experience in your KX1200.
What are the features that a keyboard amp ifier shou d have? We , ets take a ook at your gear. You sure y
have a coup e of keyboard instruments and expanders, which youd ike to connect to one and the same amp
 at the same time. No prob em with the KX1200. After a , it features four separate channe s. Probab y, you
a so have an effects device to give that be oved organ sound the finishing touch. Here, too, your KX1200 is we
equipped in that it features a separate effects path, i.e. each of the four channe s can have its own effect
intensity.
What about your voice? Wou dnt you ike to sing at east some of the songs you composed? We knew you
wou d. Thats why we equipped the KX1200 with an input for your microphone.
We , and fina y your drum computer and CD p ayer oaded with samp ing CDs: simp y connect them to the
tape input. And your headphones? We , no need to ask
Now weve come fu circ e: ast time you rehearsed with your band, you occupied six channe s p us effect path
on the conso e; now you on y need one amp occupying just one conso e channe . Your co-musicians wi be
gratefu for that! And by the way: basica y, the guitar or bass p ayer in your band cou d a so use your KX1200,
as ong as you dont need a four channe s for your keyboards equipment.
No ater than now it becomes c ear that your KX1200 is anything but a conventiona  keyboard amp, doesnt it?

or other machine providing audio p aybacks.
18 Connect the FX RETURN to the output of an externa effects device.
+The FX RETURN can also be used to feed in the output signal from an external amplifier.
19 Connect the FX/MON OUT to the input of an externa 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) a ows you to connect a microphone.

2. WIRING EXAMPLES
2.1 Standard keyboard set-up with external drum computer and effects device
The standard set-up a ows you to connect your entire keyboard equipment. Instead of the drum computer you
cou d a so use some sort of p ayback provided, for examp e, by a tape deck or CD p ayer.
Fig. 2.1: Standard set-up
2.2 xpanded P.A. set-up with four instruments, microphone and connection to a
recording console
For sma gigs or rehearsa s with a band we recommend using the wiring scheme be ow, 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 ish to connect an electric guitar, e recommend that you process the signal
before ith a guitar preamp that features a speaker simulation circuit. Other ise, the guitar
sound ill suffer from excess presence in the treble range. The outputs of guitar preamps are
usually equipped ith a speaker simulation circuit.
