1. INTRODUCTION
The Tornado series is a miniature sound source designed for high-quality distributed systems. Housed
in a compact aluminium enclosure, the Tornado is suitable for space sensitive and architectural design
installations.
The Tornados are a turn-key loudspeaker solution; designed as passive speakers, they can be easily
converted into self-powered devices by inserting the KA1-T2H, 12V/24V amplifier module.
All Tornado models are also available in a 70V version that can be powered with up to 100 units by a
single KA84 amplifier channel and up to 50 units by two bridged KA24 amplifier channels.
Tornados have a proprietary 2” high efficiency drive unit with a neodymium magnet structure and a
suspension engineered for maximum linear excursion and minimum residual transducer interference. The
cone transducer delivers an impressive maximum peak SPL of 107dB, and has a wide operating frequency
range from 150 Hz to 18 kHz with very low distortion.
In addition to the standard features of the Tornado loudspeakers, the KTL2 and KTL2C have 7 integrated
RGB LEDs that can be controlled thanks the wide range of K-array accessories via DMX or by remote. With
its ability to effortlessly reproduce speech, music and lighting, it is an excellent choice for fixed applications
such as theatres, museum displays, restaurants, portable systems for corporate AV presentations,
department stores, and in hidden locations such as chancel steps in houses of worship.
The KT2 and KTL2 come with a wall bracket for fixed installations or surface applications. The KT2C and
KTL2C come with ceiling brackets for ceiling mounts.
All Tornado components are designed by the K-array R&D department and custom made under the
K-array quality control system.

5. SAFETY INFORMATION
WARNING
• Install the speaker only in a location that can structurally support the weight of the unit. Doing
otherwise may result in the unit falling down and causing personal injury and property damage.
• Professional loudspeakers are capable of producing extremely high sound levels and should be used
with care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for
an extended period.
• Do not operate the speaker for an extended period of time with the sound distorting. This is an
indication of malfunction, which in turn can cause heat to generate and result in a fire.
• Never stand close to loudspeakers driven at high level.
• Suspending the system should only be done by qualified personnel following safe rigging practices.
Secure fixings to the building structure are vital. If in any doubt, seek help from architects, structural
engineers or other specialists.
• No naked flame sources such as lighted candles should be placed near the device.
• Do not attempt to disassemble the unit. The unit contains no user serviceable parts.Repairs should be
performed only by factory trained service personnel.
6. UNPACKING
Each K-array amplifier is built to the highest standard and thoroughly inspected before leaving the factory.
Upon arrival, carefully inspect the shipping carton, then examine and test your new amplifier. If you
find any damage, immediately notify the shipping company. Only the consignee may institute a claim
procedure regarding the system’s electronic equipment.
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. 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.
