1. INTRODUCTION
2. KEY fEaTURES
3. aPPLICaTIONS
The KZ12 is a remarkable, ultra-micro line array designed for discreet use in a variety of situations, such
as restaurants, bars, and museums.
This rugged unit contains a line array of four 0.5” excursion, full-range drivers housed in a sleek case
built around a super strong chassis. The high efficiency drive units have Neodymium magnet structures
and suspensions engineered for maximum linear excursion and minimum residual transducer noise.
This miniature, slim column is a mere 1.2cm deep and delivers true crystal clear audio with an amazing
continuous output of 92dB which is remarkable from such a miniscule enclosure. The KZ12 weighs only
46g and measures 2.1 x 10.0 x 1.2cm (0.8”x 3.9”x 0.5”).
The system delivers long throw and coherent coverage making it ideal for use in space-constrained
situations. Up to four KZ12 units can be integrated with the KU36 sub bass, extending the frequency
range to 35Hz.
All the components are designed inhouse at our Florence-based R&D department. They are custom
manufactured to our exacting standards and quality control.

4. SafETY INfORMaTION
Warning: Failure to follow these safety instructions could result in injury
or damage to the device or other property.
IMPORTANT SAFETY INSTRUCTIONS
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions and keep all warnings.
• 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 tipover.
• 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.
• 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.
• Do not make repairs yourself. Never attempt to disassemble, repair or modify the system yourself.
Disassembling the unit may cause damage that is not covered by the warranty. The device contains
no user-serviceable parts. Repairs should only be performed by factory trained service personnel.
• 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.
• Carrying, handling and installing the device. The device contains sensitive components. Do not
drop, disassemble, open, crush, bend, deform, puncture, shred, incinerate or paint the device nor
insert foreign objects into it. If your device has been dropped or damaged, unplug the power cable
immediately.
• Setup. Set up your device on a stable, horizontal surface. If combined or mechanically connected with
other products, always verify the stability of the resulting system. Install the unit only in a location
that can structurally support the weight of the unit and far away from interference with the stability
of the system. Ensure the wind does not interfere with the system’s stability, using extra securities
such as chains, weights, ropes or any other certified anchoring systems. Otherwise a unit could fall,
causing property damage, personal injury or even death. The system should only be suspended by
qualified personnel following safe rigging practices. Securing fixtures to the building structure are
vital. To clarify any doubts, seek help from architects, structural engineers or other specialists.
