FOREWORD
Dear Customer,
Welcome to the team of POWERPLAY 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 POWERPLAY has for quite a long time been a standard tool used by numerous studios and
P.A. 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 weve achieved.
It is our philosophy to share our joy with you, because you are the most important member of the BEHRINGER

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: 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 POWERPLAY PRO has made it all possible. Everybody has made very personal contributions, starting from the designers of the unit via the many staff members
