CONNECTING MIXERS ETC...
Which equipment is right for your amplifier?
All audio input connections on all KXR Amplifiers operate strictly at Line Level. This means that, providing
you have an appropriate cable, you can connect any Line Level audio device to the input connections on the
back of your amp'. For most circumstances this means using a mixer... this can be a DJ mixer or a
mixing console of the type used to combine various instruments when mixing a live band etc. In some
circumstances you might wish to connect a CD, MP3, DAT, Cassette Player etc or any other line level
device directly to the Line Input connections and this should work quite safely... but it is more common to
use a mixer of some sort to enable you to combine several sound sources and to provide additional overall
volume control. Your amplifier IS NOT designed to accept input connections directly from microphones. If
you wish to use a microphone you'll need to connect the microphone to a mixer (so that the mixer can
convert the Mic Level signal to a Line Level signal) and then connect the mixer to your amp'.
Connection types
Balanced XLR. All models of KXR amplifier feature line level balanced XLR audio input sockets. If your
equipment features appropriate balanced XLR audio outputs and you have an appropriate cable we
recommend using this connection type.
Unbalanced Jack. All KXR amplifiers also feature unbalanced Jack input sockets.
Line Level RCA Phono. Two models of KXR amplifier feature line level RCA Phono input connections; the
KXR150 & KXR300. This is simply because these two models of amplifier provide a power output level
that it suited to home use or for performances in bars etc. RCA Phono is a domestic audio connection
type. It is important to note that these are Line Level RCA Phono connections... NOT 'Phono' Level RCA
Phono connections. This means you cannot connect the output from a standard turntable (unless your
turntable has a built in pre-amplifier and specified line level RCA Phono outputs). You must connect a
standard turntable to a DJ mixer (or other appropriate pre-amplifier) so that the mixer can boost the
'Phono Level' turntable output signal to the 'Line Level' that is right for your amplifier.
PROCEDURE
•
Always ensure that the volume controls on your KXR amplifier are turned to zero and that
it's mains power is switched off when making connections.
•
If you look at the output connections on your mixer etc you should see that there are two
sockets, one marked 'left' or 'L' and the other marked 'right' or 'R'.
•
Almost all mixers will also colour code all of the audio input and output connections using
a simple rule; Red = Right, White = Left. If you purchase a commercially produced audio cable you will
often find that the connectors are colour coded to help you follow the rule.
•
Use an appropriate audio cable to connect the left channel of the output from your mixer
to the input marked channel A on your amplifier... and connect the right channel of the output from
your mixer to the input marked B on your amplifier.
•
If you have already connected up your speakers you are ready to move on to turning on
and using your equipment.
ALWAYS TURN ON YOUR EQUIPMENT IN THE FOLLOWING ORDER;
1. Turntables, CD players etc – but don't start playing any music yet
2. DJ mixer (if you use one) – but make sure that the output volume is at zero
3. KXR amplifier
