ULTRA-Q PRO PEQ2200

FOREWORD

Dear Customer,

Welcome to the team of ULTRA-Q PRO users and thank you very much for expressing your confidence in

BEHRINGER products by purchasing this unit.
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

better still. The ULTRA-Q PRO has for quite a long time been a standard tool used by numerous studios and

PA rental companies. The task to improve one of our best-selling products 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 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 to produce such high-grade devices at such unbelievably low prices.

The answer is quite simple: it’s you, our customers! Many satisfied customers means large sales volumes

enabling us to get better conditions of purchase for components, etc. 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 ULTRA-Q 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
