Welcome to the team of ULTRABASS PRO users and thank you very much for expressing your confidence in BEHRINGER products by purchasing the EX1200.

The task to design the ULTRABASS PRO 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 it’s a great feeling, 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.

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 possible to produce such high-grade devices at such unbelievably low prices. The answer is quite simple: it’s you, our customers! Many satisfied customers mean large sales volumes, enabling us to get better conditions of purchase for components. 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 ULTRABASS 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.
