SYMBOLS
• 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.
• 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
2. INTRODUCTION
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 (except
in model “N”) 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
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.
3. 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 , 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..
