KA line
K-array is the new voice that sings
aloud, "outside the choir", and
whose performance is better than
any other products.
Born on-the-road, in the PA world,
where you get no discount, you have
to give your best as fast as you can,
often with a "compressed" budget, K-
Array systems have been designed to
give precise answers to precise
needs.
Driven by new generation digital
engine, with power/dimension/weight
ratios that are ten times better than
any other professional products, K-
arrays can deliver the full spectrum of
musical styles with clarity, power,
punch, intelligibility and evenness
across both volume levels and the
frequency spectrum. These systems
can be remotely controlled and come
w i t h a s o p h i s t i c a t e d o n - b o a r d
software, allowing the user to shape
their performance to taste and needs.
Inside K-array systems you will find
something that only we can offer: the
b e s t i n t e c h n o l o g y, p r o u d l y
conceived, designed and produced in
Italy. If they were cars, they would be
Ferrari. Don't agree to pay for a
simple brand, claim performance,
and don't believe those who maintain
that these products are only for few
people, the only truth is that K-array
systems are unique, but affordable
and within everybody's reach!

USER'S MANUAL P. 2
CAUTION !
!
1. SAFETY INSTRUCTIONS
• To reduce the risk of electric shock, disconnect the amplifier from the AC mains before installing audio
cable. Reconnect the power cord only after making all signal connections.
• Connect the amplifier to a two-pole, three wire grounding mains receptacle. The receptacle must be
connected to a fuse or circuit breaker. Connection to any other type of receptacle poses a shock hazard and
may violate local electrical codes.
• Do not install the amplifier in wet or humid locations without using weather protection.
• Do not allow water or any foreign object to get inside the amplifier. Do not put objects containing liquid on,
or near, the unit.
• To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight. Do not install the unit
near heat emitting appliances, such as a room heater or stove.
• No naked flame sources such like lighted candles should be placed on the device.
• The amplifier should be placed so that its location does not interfere with its proper ventilation. For
example, the appliance should not be situated on a bed, carpet, or similar surface that may create an
obstacle for the ventilation openings.
• CAUTION, RISK OF ELECTRIC SHOCK, DO NOT OPEN. This amplifier contains potentially hazardous
voltages. Do not attempt to disassemble the unit. The unit contains no user serviceable parts. Repairs should
be performed only by factory trained service personnel.
• Be sure that both voltage set by the selector on the device and AC Power have the same value.

USER'S MANUAL
KA 10 operates safely and without audio discontinuity if the AC voltage stays within either of two operating windows: 9 5 - 1 2 5
(voltage selector on 115 V) or 195-250 V (voltage selector on 230 V), at 50 or 60 Hz.
5. VOLTAGE REQUIREMENTS
115-230
Connecting a 115V system on a 230V AC Power causes heavy
damages to the device and serious risk for users .
CAUTION
!
The device is default set to be connected to 230 V AC Power. To use the device on a 115 V AC Power you need, before connecting it,
to move the voltage selector's cover, just loosening the two screws, and to choose the correct use voltage by the red switch. Be
sure that both voltage set on the selector and AC Power have the same value . Always close the voltage selector's cover before
connecting the device to AC Power. Change the label that points out the correct voltage in use..
KA10-10
The KA professional rack amplifier line has been designed to give
answers to all the needs of touring and installation applications
in which a large amount of power is needed together with the
maximum flexibility, over low sizes and weight. The sophisticate
electronics on-board allow to reach outstanding output power
levels with over-high efficiency. DSP on-board can provide
perfect signal processing for all K-array products, providing safe
working conditions and a large choice of dedicated presets to
solve the most parts of the needs of high-end applications. A
dedicated remote control ensures a constant connection with all
the units, allows the total management of the presets installed
and the possibility of the download of new ones.

A powerful DSP manages all the functions of the speakers. Each system can store on board 16 preset that can be recalled pushing
the PRESET button. Once the preset will appear on the lower line of the display it will become automatically available after few
seconds. If you desire to set a preset as “default” you just need, once selected it, to keep pressed for five seconds the PRESET
button. After that, this preset will automatically be recall each time you will switch on your module. It is also possible to remote each
module by an RS485 serial port. In order to remote your system, you need to set each module on a different address, so that, in your
chain, no one module will have the same address. Two rotary encoders allow you to set the desired address number that will appear
on the top line of the display. Using the remote control software it is possible to mute each system, select a desired preset loaded on-
board or download a new preset pack.
For remote control operation please refer to REMOTE CONTROLAND SOFTWARE MANUAL in the next pages.
8. DSP CONTROL & REMOTE CONTROL
8.1 Cloner function & preset systems
It is possible to clone the entire presets bank from Speaker to Speaker without any PC connected. We will call
SpeakerA the one with the presets bank that you want clone, and SpeakerB the one that will be upgraded.
Set the SpeakerA on ID 99, will appear CLONER on the display
Keep SpeakerB on any ID number between 10 and 90.
Turn off both the speakers and connect by a RJ45 8 poles cable
Turn on the SpeakerB and after the SpeakerA
SpeakerA will start to clone, on the display will appear a cont down (00/15, 01/15, etc)
Wait till 20 seconds after 15/15
Change the ID of the SpeakerA to any other ID and turn off both Speakers
Turning on the SpeakerA check that it is on mode 16x16 and NOT 4x4.
If SpeakerA is in mode 4x4, just turn off the speaker and keep press the Preset button during the turning on
The preset are cloned to the SpeakerB.

9. REMOTE CONTROL SOFTWARE
1 . To connect the K-array modules to a PC, it is needed a RS485-USB adapter, we recommend the K-USB adapter (pic.1).
2 . Install the K array control software from installer in the CD-ROM
2.1 Start the Karray_manager_V2 from Windows - Start - Software - Karray_manager_V2
2.2 Click on NO when ask for demo mode start
2.3 Click on System - Settings to configure which COM port use, the COM port of K-USB, usually is the higher number.
If you don't find, you can check it on windows-control panel-system-hardware-COM Port
Connect the K-usb to a PC and install the drivers required included in the CD-ROM.

Module status panel
This frame describes the state of all the loudspeakers on the net.
The colour of the little rectangles into this frame represents the
status of the loudspeakers. Each loudspeaker has three rectangles.
Here there is the meaning of the rectangle's colour.
Two rectangles on top:
Both rectangles grey: the loudspeaker is not present on the net.
Temperature rectangle red: one module inside that loudspeaker is
over-temperature.
Temperature rectangle green: all modules inside that loudspeaker
have a good temperature.
Protection/Fail rectangle red: at least one module inside that
loudspeaker is in protection.
Temperature rectangle green: all modules inside that loudspeaker
are working properly.
Temperature rectangle black: if this rectangle is black it means that
the loudspeaker is not responding.
The main causes of this malfunction are
loss of power supply and loss of serial
connection between the hub and the
loudspeaker. Check the hardware. If
this rectangle is black will be black also
the Protection/Fail.
Protection/Fail rectangle black: see
above.
The remaining rectangle: Is related to
the mute function; if red, the related
loudspeaker is in "mute" status.
