Dear Customer,

Welcome to the team of POWERPLAY PRO users and many thanks for the confidence that you have shown in us by purchasing the HA4600. It is one of my most pleasant tasks to write this letter to you, because after many months of hard work our engineers have achieved a very ambitious goal: the presentation of an outstanding piece of equipment, which thanks to its flexibility can be used both in studios and by in live sound applications. The task of developing our new POWERPLAY PRO has meant a great deal of responsibility. As we continued to develop it further, you—the discerning end-user and musician—were always at the forefront of our thoughts. Meeting this responsibility also involved us in considerable effort and late-night working, but it was fun, too. This type of development always brings together a large number of people, and it is a great feeling when all those involved can be proud of the results of their work.

Our philosophy is that you should also share in this satisfaction. You are the most important member of our team. With your highly competent encouragement and suggestions for new products, you have greatly contributed to shaping our company and to making it successful. In return we guarantee you an uncompromising level of quality (manufactured under ISO9000 certified management system), excellent technical and audio characteristics and an extremely favorable price. All this makes it possible for you to develop your fullest potential, without being hampered by budget constraints.

We are often asked how we manage to manufacture equipment of this quality at such unbelievably low prices. The answer is very simple: You make it possible! Many satisfied customers means large sales volumes. Large sales volumes means we can get better purchase prices for components etc. Isn’t it only fair for us to pass this benefit back to you? After all, we know that your success is our success, too!

I would like to thank everyone who has helped make the POWERPLAY PRO possible. All have made their own personal contribution, beginning with the developers, through the many employees of our company and up to you, the user of BEHRINGER products.

My friends, it’s been worth the trouble!

Thank you very much,

Uli Behringer
