1. INTRoDUCTIoN
The Owl KW8 is a self powered audio moving head including a coaxial 8” transducer and a newly
built-in camera to allow users to accurately direct sound. This feature bridges the gap between AV in
a revolutionary concept. The Owl provides up to 500 W of power, 120 dB of SPL (continuos) and a
frequency range from 60 Hz to 19 kHz.
It is a perfect solution for a range of applications including live on-stage monitoring, theme park
installations, airports, train stations, DJ effects and theatre installations. However, the flexibility of
the Owl will offer an almost limitless number of solutions and, in some cases, reduce the amount of
speakers required for an installation.
The Owl is part of K-array’s portfolio of concert systems but was designed as an alternative solution
for the most ambitious projects. Its dedicated software gives you the ability to control the settings,
movement, sound and video together allowing you to create scenes and setups via DMX, audio balanced
signal and the HD-SDI onboard camera.

WARNING
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, has been exposed to rain or moisture, does not operate
normally, or has been dropped.
• Since the device is a CLASS I apparatus, it must be connected only using an AC three-wire
grouding outlet. If your outlet isn’t grouded, contact a liscensed 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 to a higher volume of sound that over time
may sound normal but can be damaging to your hearing. Hearing loss worsens after exposure 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 power connection satisfies the power ratings of the device.
• Only connect the power supply to an appropriate power outlet.
• Do not install the device in wet or humid locations without using weather protection.

All speakers and the connected audio equipment (mixing consoles, processors, etc.) must be connected
to the AC power distribution in a proper way, preserving AC line polarity and ground connection such
that all grounding points are connected to a single node or common point using the same cable
gauge as the neutral and line(s) cables. Bad grounding connections between speakers and the rest of
the audio system may produce noise, hum and/or serious damage to the input/output stages in the
system’s electronic equipment.
CAUTION. Before applying AC to any K-array self-powered
speaker, be sure that the voltage potential difference between
neutral and ground is less than 5 VAC.
