EUROLIVE PROFESSIONAL SERIES

Foreword
Dear Customer,
welcome to the team of
EUROLIVE users, and
thank you very much for
expressing your confi-
dence in us by purchasing
these PA loudspeakers.
Writing this foreword for
you gives me great ple-
asure, because it repre-
sents the culmination of
many months of hard work
delivered by our enginee-
ring team to achieve a very
ambitious goal: to develop
an outstanding PA system
that offers a maximum in
exibility and performance
through its impressive
sound character and out-
standing features. The
task of designing our new
EUROLIVE PROFESSIONAL SERIES certainly meant a great
deal of responsibility, which we assumed by focusing on you, the
discerning user and musician. Meeting your expectations also
meant a lot of work and night shifts. But it was fun, too. Develo-
ping a product usually brings a lot of people together, and what a
great feeling it is when all who participated in such a project can
be proud of what they’ve achieved.
It is our philosophy to share our enjoyment with you, because you
are the most important member of the BEHRINGER team. With
your highly competent suggestions for new products you’ve made
a signicant contribution to shaping our company and making it
successful. In return, we guarantee you uncompromising quality
as well as excellent technical and audio properties at an extremely
reasonable price. All of this will enable you to give free rein to your
creativity without being hampered by budget constraints.
We are often asked how we manage to produce such high-quality
devices at such unbelievably low prices. The answer is quite
simple: it’s you, our customers! Many satised customers mean
large sales volumes enabling us to get better purchasing terms
for components, etc. Isn’t it only fair to pass this benet on to you?
Because we know that your success is our success too!
I would like to thank all of you who have made the EUROLIVE
PROFESSIONAL SERIES possible. You have all made your own
personal contributions, from the developers to the many other
employees at this company, and to you, the BEHRINGER user.
My friends, it’s been worth the effort!
Thank you very much,
Uli Behringer
