FOREWORD

Dear Customer,
Welcome to the team of EURORACK 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: To produce a compact mixer,
which fully satisfies your and our expectations and delivers a superior sound quality, easy operation and
technical specifications. In addition to that the mixer is affordable for almost every musician. The task to design
the EURORACK MX802A certainly meant a great deal of responsibility, which we assumed by focosing 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

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!
