1. INTRODUCTION
The KR systems are integrated, self-powered speaker systems featuring mid-high line array elements
matched to powered subwoofers. All systems feature two channels of Class D amplification housed in
the subwoofer(s). The rear panel provides input for 2 balanced line signals and a digital signal in AES/
EBU protocol. And with the K-dante accessory, the system can be used in a Dante network.
An integrated touch screen provides intuitive managing and editing of powerful DSP controlling: input
and output levels, In/Out routing, subwoofer delay up to 12 ms, Speakon output to the mid-high element
with delay of up to 12 ms, and overall system delay up to 330 ms. All DSP functions, including EQ can
be controlled with remote managing software via USB or RS485, again, conveniently on a standard XLR.
The Mark I version is the newest version of the KR102, KR202 and KR402 systems, featuring new auto
range amplifiers, new codecs that reduce the signal/noise ratio, a 5v dc power connector on the rear
amplifier panel and enhanced functionality for creating presets. The output AES/EBU is now latency-free
(through) and other updates include a larger LCD screen (2.8”), the removal of the e-fun connector and
a new paint job for the mid-high elements. All these features are included in the KR802 as well.
All KR systems are designed by the K-array R&D department and custom made under the K-array quality
control system.

• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
• Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding
prong. The wide blade or the third prong are provided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
• Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with
the apparatus.
• When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from
tip-over.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus

WARNING
• Since the device is a CLASS I apparatus, it must be only connected to an AC three-wire grounding outlet.
If your outlet isn’t grounded, contact a licensed electrician to replace it with a property grounded
outlet.
• To reduce the risk of electric shock, unplug the AC mains connector before installing audio cable.
Reconnect the power cord only after making all signal connections. Do not use the product if the
power cord is broken or frayed. Protect the power cord from being walked upon or pinched.
• To completely disconnect this apparatus from the AC mains, disconnect the power supply cord plug
from the AC receptacle.
• Avoiding hearing damage. Professional loudspeakers are capable of producing extremely high sound
levels and should be used carefully. Never stand close to loudspeakers driven at high volume. Set
the volume to a safe level. You can adapt over time to a higher volume of sound that may sound
normal but can be damaging to your hearing. Hearing loss get worse every time you’re exposed to a
sound level of 90 dB or over for an extended period of time. If you experience ringing in your ears
or muffled speech, stop listening and have your hearing checked. The louder the volume, the less
time is required before your hearing could be affected.
• Voltage requirement. Make sure that the supplied voltage stays within the specified range. Verify that
your mains connection satisfies the power ratings of the device.
• Only connect the power supply to an appropriate power outlet
• Do not install the amplifier in wet or humid locations without using weather protection.
• TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, do not expose this apparatus to rain or moisture
and objects filled with liquids, such as vases, should not be placed on this apparatus.
• The main plug of the power supply cord shall remain readily accessible.
CAUTION
• Choking Hazards. This device contains small parts, which may present a choking hazard to small
children. Keep the device and its accessories away from small children.
• It is important that loudspeaker systems are used in a safe manner.
• Do not make repairs yourself. Caution, risk of electric shock. Do not open the device, it contains
potentially hazardous voltage. Never attempt to disassemble, repair or modify the system yourself.
Disassembling the unit may cause damage that is not covered under the warranty. The device
contains no user-serviceable parts. Repairs should only be performed by factory trained service
personnel. Do not plug the power cord in if you suspect that your device needs service or repair.
• Sound distortion. Do not operate speakers for an extended period of time with sound distortion. This
is an indication of malfunction, which in turn can generate heat and result in a fire.
• Cooling. During the use, it is normal for the device to get warm. The exterior of the device functions
as a cooling surface that transfers heat from inside the unit to the cooler air outside. The device
