TUBE ULTRA-Q T1951

FOREWORD

Dear Customer,
We thank you for expressing your confidence in BEHRINGER products by purchasing the BEHRINGER

TUBE ULTRA-Q. It is one of my most pleasant tasks to write this preface, as our engineering team has made

it possible to enhance the traditional tube circuitry design (particularly for our VINTAGER series of products),

and adapt it to meet the high sound quality and dynamics requirements of modern, pro-level audio technology.

The fact that we are still fascinated by “antique” tube radios and amps as well as the fine and warm tonal

character that we usually associate with them, are the reasons why vacuum tubes have kept their ground even

in state-of-the-art circuit topologies used especially in professional audio technology or high-end devices. We

are particularly proud that we have found an extremely effective symbiosis between solid-state and tube

technologies making them affordable to anybody interested in audio technology. As always, our top-priority

concern when developing this device was the demanding end user, in other words: you. It was our major goal

to meet your demands. Sure, it meant a lot of hard work to develop such a product, but the fun has made it all

worthwhile. The shine in the eyes of the many interested musicians at the Music Fair 1997, when they saw our

VINTAGER models for the first time, was a lasting incentive driving our development efforts.
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 (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!
I would like to thank all people whose help on “Project TUBE ULTRA-Q” 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.

My friends, it’s been worth the trouble!

Thank you very much,

Uli Behringer
