Congratulations on your purchase of the K-Array KA10.
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.
Each K-array device is built to the highest standard and thoroughly inspected before leaving the factory.
Carefully inspect the shipping carton before opening it, and then examine and test your new loudspeaker. If
you find any damage immediately notify the shipping company. Only the consignee may institute a claim for
damages incurred in shipping. It is suggested that you retain the original packaging so that the amplifier can
be repacked at a future date if necessary.
Please note that K-array and its distributors cannot accept any responsibility for damage to any returned
product through the use of non-approved packaging.

WARNING !
!
• 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 andAC Power have the same value.

KA 10 operates safely and without audio discontinuity if the AC voltage stays within either of two operating
windows: 95-125 (voltage selector on 115 V) or 195-250 V (voltage selector on 230 V), at 50 or 60 Hz.
115-230
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 , 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.

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
11.1 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.
12. DSP CONTROL AND REMOTE CONTROL
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.

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.
