FOREWORD
Dear Customer,
Welcome to the team of
BEHRINGER users, and
thank you very much for
expressing your confidence in us by purchasing the BEHRINGER
ULTRABASS.
Writing this foreword
for you gives me great
pleasure, because it
represents the culmination of many months
of hard work delivered
by our engineering
team to achieve a very
ambitious goal: to
present you with an
outstanding bass
amplifier that is at the
forefront of what is technically possible and that offers you a
vast variety of sound shaping options.
The task of designing our new ULTRABASS 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 highquality 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 ULTRABASS
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.
