OVERVIEW
Congratulations on your choice of new amplifier… cool isn’t it? We are certainly very proud of it. We
believe in giving you products with the features and performance you want at a price you can afford and the
KXR Amplifier range is living proof of our commitment to meeting that goal. We know you’re itching to get it
fired up but bear with us and we’ll run through a few things you should know that will help you get the best
from your new amplifier and ensure that it lasts as long as you want it to.
There are six models in the KXR Amplifier range
KXR150
150W RMS amplifier
KXR300
300W RMS amplifier
KXR600
600W RMS amplifier
KXR1000
1000W RMS amplifier
KXR1500
1500W RMS amplifier
KXR2000
2000W RMS amplifier
Although there are six different models in the range and some of them do vary slightly in input
configuration, the main difference between each model is their maximum power output. This means that
the basic principles of amplifier connection and usage are true for all six models. Below we outline basic
operation procedures and tell you about any differences that are particular to specific models.
SAFETY NOTE
ALWAYS
turn off the mains power before making any connections to KXR amplifiers. Large PA amplifiers
are capable of sending potentially lethal amounts of electricity to their outputs so you should always
ensure that any amplifier has its power turned off (and preferably disconnected) before making
connections.
NEVER
attempt to connect a microphone to the speaker outputs of an amplifier.
CONNECTING SPEAKERS…
WHICH SPEAKERS ARE RIGHT FOR YOUR AMPLIFIER?
Passive only
Your KXR Amplifier is designed to be used in conjunction with a set of passive speakers. This means that
they’re good for use with most (providing you follow the rating and connection procedures below) speaker
types that don’t have built in amplification; in the context of the Kam equipment range this means your
KXR amplifier is ideal for use with our IMS Pro10, IMS Pro12 & IMS Pro15 speakers (or our standard
IMS or Z Series speakers) but it is not needed with our IMS Pro12A or IMS Pro15A ‘active’ speakers
because they already have built in amplification.
Power & Impedance
It is important to ensure that you match the power that your speakers can handle with the power that
your amplifier can produce.
Speaker Rating
A set of speakers has two stated ratings.
They should have a maximum power handling capacity that is measured in Watts (EG 300W). This tells
you how much power the speaker can handle from the amplifier before the sound distorts and damage
begins to occur.
A speaker will also have what we call an ‘Impedance’ rating. Impedance is a term we use to define the
amount of resistance your speaker presents to your amplifier and it is measured in ‘Ohms’. Most
speakers have an Impedance rating of 8 Ohms but ratings of 4 Ohms are not uncommon and sometimes
