1. INTRODUCTION
K-Array technology delivers what others cannot; the latest innovation from K-Array is the
Kobra KK50vb.A revolutionary variable beam line array that marks a milestone in PA
technology.
The KK50vb is a high technology 3D line array speaker system that can produce extremely
high sound pressure levels with unprecedented quality.
This symbol alerts the user to the presence
of recommendations about product's use
and maintenance.
K-Array are masters in the art of producing stylish compact systems that deliver far more than
seems plausible from such tiny enclosures. Now the KK50vb moves the goal post even further
from the competition with its patented (pending) variable beam engineering.
All Kobra systems have the ability to be mounted in the traditional vertical manner or
horizontally making them all but invisible in situations such as TV studios, places of worship,
etc. The KK50vb has another advantage: it can change the coverage from the usual 7° to an
amazing 120° at the mere flick of a switch. This ability coupled with its diminutive size and
weight make this an unparalleled line array system that is perfect for almost any venue from
small clubs to large outdoor events.
The KK50vb's rugged military spec enclosure is built to stand the rigours of heavy touring, but
not at the expense of weight and size. It contains a line array of 8 1" high efficiency drive units
with neodymium magnet structures and suspensions engineered for maximum linear
excursion and minimum residual transducer noise.
This tiny slim column is a mere 5,6 cm deep and weighs in at an extremely modest 2 Kg, yet it
delivers true crystal clear audio with an output of 114dB continuous.
