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 par

ticular amplifier will deliver gr

eater power to a pair of 4 Ohm speakers

than it would to a pair of 8 Ohm speakers.

NOTE Connecting multiple speakers to a single amplifier alters the impedance rating of the
speakers. For guidance on this visit www.kam.co.uk/tuition.

KXT amplifiers require speakers with a minimum Impedance rating of 4 Ohm.
They will work just as well with speakers rated at 8 Ohm but the volume achieved from
your speakers will be different for 4 and 8 Ohm speakers. The chart below tells you the
power output ratings for KXT amplifiers at 4 and 8 Ohms.

FRONT PANEL CONTROLS

[1] Mains Power switch - use this to switch the mains power on/off.
[2] Power LED - when the power is on the blue power LED will light.
[3] Volume controls - used to adjust overall volume for each channel.
[4] Signal Indicator LEDs - each channel has a single green Signal Indicator LED which

lights whenever a signal is present.
[5] Clip Indicator LED - each channel has a single red Clip Indicator LED which only
illuminates when an excessive signal is present.

An optimum operating level is one where the Signal Indicator LED lights to show that the
amplifier is working and the Clip indicator LED lights very occasionally.

[6] Protect LED - these amber LEDs illuminate when one of the following 'Protection'
mechanisms has engaged;
