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

Read these instructions - Keep these instructions - Heed all warnings
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.
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.

6. UNPACKI NG

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.
