FOREWORD
Dear Customer,
welcome to the team
of EUROLIVE users,
and thank you very
much for expressing
your confidence in us by
purchasing these PA
loudspeakers.
Writing this foreword
for you gives me great
pleasure, because it
represents the cul-
mination of many months
of hard work delivered
by our engineering team
to achieve a very
ambitious goal: to
develop an outstanding
PA system that offers a
maximum in flexibility and
performance through its impressive sound character and
outstanding 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. Developing
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 significant 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 satisfied customers
mean large sales volumes enabling us to get better purchasing
terms for components, etc. Isn’t it only fair to pass this benefit 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
