USER'S MANUAL
K-array is the new voice that sings aloud, "outside
the chorus", and whose performance is better than
any other products. Born on-the-road, in the PA
world, where you get no discount, you have to give
your best as fast as you can, often with a
"compressed" budget, K-Array systems have been
designed to give precise answers to precise
needs. K-Array systems are driven by new
generation digital engines, with
power/dimension/weight ratios that are ten
times better than any other professional
products; these systems can be remotely
controlled and come with a lot of on-board
software. K-array systems can shape their
performance following your taste and
needs. Inside K-array systems you will
find something that only K-array can
offer: the best in technology, proudly
conceived, designed and produced in
Italy. If they were cars, they would be
Ferrari. Don't agree to pay for a
simple brand, claim performance,
and don't believe those who
maintain that these products are
only for few people, the only truth
is that K-array systems are
unique, but affordable and within
everybody's reach!
