ULTRA-DI PRO DI800

FOREWORD

Dear Customer,

welcome to the team of BEHRINGER users, and thank you very much for expressing your confi- dence in us by pur- chasing the DI800.

Writing this foreword for you gives me great pleasure, because it represents the culmi- nation of many months of hard work delivered by our engineering team to achieve a very am- bitious goal: to develop an outstanding piece of equipment, whose flexi- bility makes it ideally suited for use in studios

as well as in P.A. systems. The task of designing our new ULTRA-DI PRO certainly meant a great deal of responsibility, which we assumed by focusing on you, the discerning user and musician. Meeting your expectations also meant a lot of work and night shifts. But it was fun, too. Developing a product usually brings a lot of people together, and what a great feeling it is when all who participated in such a project can be proud of what they’ve achieved.

It is our philosophy to share our enjoyment with you, because you are the most important member of the BEHRINGER team. With your highly competent suggestions for new products you’ve made a significant contribution 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 reasonable price. All of this will enable you to give free rein to your creativity without being hampered by budget constraints.

We are often asked how we manage to produce such high- quality 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 purchasing terms for components, etc. Isn’t it only fair to pass this benefit on to you? Because we know that your success is our success too!

I would like to thank all of you who have made the ULTRA-DI PRO possible. You have all made your own personal contributions, from the developers to the many other employees at this company, and to you, the BEHRINGER user.

My friends, it’s been worth the effort!

Thank you very much,

Uli Behringer

1. INTRODUCTION

Thank you for showing confidence in BEHRINGER products by purchasing the DI800.

Be it on-stage or in the studio, musicians often look for ways to connect certain signal sources directly to the mixing console. Even though this approach has obvious advantages, there are still some technical hurdles obstructing its implementation. For example, keyboards seldom feature balanced outputs, and guitars can not be directly connected to mixing consoles because of the high impedance of guitar signals.

ADI-box lets you directly tap into a high-impedance, unbalanced signal—for example, the signal between a guitar and a guitar amp. From there on, you can feed the signal directly to a mixing console.

There are active and passive DI-boxes. A passive DI-box is more affordable, but its performance is highly dependent on the impedance of the equipment to which it is connected. When the impedance on the mixing console’s end changes, so does the impedance at the DI-box’s input. A passive DI-box only functions correctly when the impedance of the connected equipment is exactly specified (high at the input, low at the output).

On the other hand, active DI-boxes, such as the DI800, are not bound by these limitations, since the signal located at the input is “buffered” by an amplifier. The input impedance of the DI800 is extremely high. It does not influence the sound source and has absolutely no effect on the signal flow though the DI-box. The output impedance is balanced and is very low, and the signal is far less susceptible to picking up noise. The ULTRA-DI PRO always transmits signals optimally, independent of the impedance of the connected equipment.

In addition to being powered by a mains connection, the ULTRA-DI PRO DI800 can also run on phantom power provided by your mixing console.

+To avoid damaging your loudspeakers, always first connect the DI-box and only then open up the respective channel strip.
