OVERVIEW
Your KXT Amplifier is a high quality, high power professional PA amplifier with an
additional 3rd channel. It is ideal for powering a 2.1 system comprising a single Sub Bass
speaker and a pair of passive satellite speakers. 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 two models in the KXT Amplifier range
KXT 22350
2 x 300W RMS + 500W RMS @ 4 Ohms
2 x 200W RMS + 350W RMS @ 8 Ohms
KXT 23600
2 x 450W RMS + 900W RMS @ 4 Ohms
2 x 300W RMS + 600W RMS @ 8 Ohms
SAFETY NOTE
ALWAYS
turn off the mains power before making any connections to KX Pro 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.
WHICH SPEAKERS ARE RIGHT FOR YOUR AMPLIFIER?
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. A set of speakers has two stated ratings.
They should have a
'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. This is often stated as two different ratings;
'RMS' which means how much power can be handled constantly… and 'Peak' which as
the name suggests means an amount of power it can handle for a short period of time.
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 you may encounter 16 Ohm or even 2 Ohm.
A speaker that is rated at 8 Ohm presents a larger amount of resistance to the
amplifier than one that is rated at 4 Ohm. As you can see from the chart below this
means that a particular amplifier will deliver greater power to a pair of 4 Ohm speakers
than it would to a pair of 8 Ohm speakers.
