FOREWORD

Dear Customer, Welcome to the team of ULTRACOUSTIC users, and thank you very much for expressing your confidence in

BEHRINGER products by purchasing the ACX1000. 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 present you with an excellent 2-channel acoustic guitar amplifier which features authentic sound quality and an integrated digital multi-effects device, not to forget the professional design.

The task to design the ULTRACOUSTIC 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.

We designed the ULTRACOUSTIC to meet the precise requirements of guitarists and vocalists alike. Our many years of experience in studio and live applications enabled us to equip the ULTRACOUSTIC with a wealth of useful features that will make your work much easier, both during recording sessions and on stage.

We designed and manufactured your ULTRACOUSTIC with great care and attention to detail, attaching particular importance to a user interface that can be operated intuitively, simply to give you fun using the ACX1000 and help you focus on your guitar work.

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 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 manage 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 the following people, whose help on “Project ULTRACOUSTIC ACX1000” has made it all possible:

▲ The existing users of BEHRINGER equipment (whose comments and suggestions have made them the

most important members of the BEHRINGER design team),

▲ Jörg for the great, new effects algorithms, ▲ Mathew and C.W. for the mechanical design, ▲ Thorsten who once again wrote an excellent manual, ▲ Uli and Stefan from STRINX acoustic duet for providing us with useful hints from practice, ▲ and all the others, who have made very personal contributions.

My friends, it’s been worth the trouble!

Thank you very much,

Uli Behringer
