FOREWORD
Dear Customer,
Welcome to the team of ULTRABASS PRO users and thank you very much for expressing your confidence in
BEHRINGER products by purchasing the EX1200.
It is one of my most pleasant tasks to write this letter to you, because it is the culmination of many months of
hard work delivered by our engineering team to reach a very ambitious goal: making an outstanding device that
will become a standard tool used by studios and PA companies. The task to design the
ULTRABASS PRO certainly meant a great deal of responsibility, which we assumed by focusing on you, the
discerning user and musician. It also meant a lot of work and night shifts to accomplish this goal. But it was
fun, too. Developing a product usually brings a lot of people together, and it’s a great feeling, when everybody
who participated in such a project can be proud of what we’ve achieved.
It is our philosophy to share our joy with you, because you are the most important member of the BEHRINGER
family. With your highly competent suggestions for new products you’ve greatly contributed to shaping our
company and making it successful. In return, we guarantee you uncompromising quality (manufactured under
ISO9000 certified management system) as well as excellent technical and audio properties at an extremely
favorable price. All of this will enable you to fully unfold your creativity without being hampered by budget
constraints.
We are often asked how we can make it possible to produce such high-grade 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 conditions of purchase for components. Isn’t it only fair to pass this benefit
back to you? Because we know that your success is our success too!
I would like to thank all people whose help on “Project ULTRABASS PRO” has made it all possible. Everybody
has made very personal contributions, starting from the designers of the unit via the many staff members in our
company to you, the user of BEHRINGER products.
My friends, it’s been worth the trouble!
Thank you very much,
Uli Behringer
