FOREWORD
Dear Customer,
Welcome to the team of ULTRA-DIPRO users and thank you very much for expressing your confidence in

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 ULTRA-DIPRO
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 what a great feeling it is when everybody who participated
in such a project can be proud of what weve achieved.
It is our philosophy to share our joy with you, because you are the most important member of the BEHRINGER

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 to produce such high-grade devices at such unbelievably low prices.
The answer is quite simple: its you, our customers! Many satisfied customers means large sales volumes
enabling us to get better conditions of purchase for components, etc. Isnt 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 ULTRA-DIPRO 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
