1. INTRODUCTION
1. INTRODUCTION
Congratulations! By purchasing the TRUTH B2092A, you have
obtained a powerful active subwoofer that effectively expands
the transmission range of your stereo or surround system. You
now own a tool that lets you reproduce the deepest bass
frequencies with outstanding clarity.
The TRUTH B2092A is a compact subwoofer capable of
reproducing bass frequencies down to 32 Hz. The band pass
enclosure design with two long-stroke 8" loudspeakers
guarantees the highest signal level with the lowest non-linear
distortion possible. The integrated electronics include active
crossovers, an overload-protection circuit and a powerful
360-Watt amplifier that delivers clearly defined bass even at
high volumes. The B2092A features 3 signal inputs and outputs
(left/center/right) as well as a separate subwoofer input. They
assure flexible connectivity options for existing monitoring
systems, regardless of whether they are in stereo or surround
sound. The input sensitivity can be adjusted; and you can optimally
adjust the B2092A to the main speakers and the acoustic
surroundings by using the multistage room and phase
compensation.
+The following users manual is intended to
familiarize you with the units control elements,
so that you can master all the functions. After having
thoroughly read the users manual, store it in a safe
place for future reference.
ATTENTION!
+The B2092A is capable of producing extreme
volumes. Please bear in mind that high sound
pressures do not only temporarily damage your
hearing, but can also cause permanent damage.
Always make sure to select an appropriate volume.
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 this studio
subwoofer.
Writing this foreword for
you gives me great
pleasure, because it
represents the cul-
mination of many months
of hard work delivered
by our engineering team
to achieve a very
ambitious goal: to
present a compact
subwoofer that perfectly
complements every loud-
speaker system with its enormous acoustic pressure and well-
defined reproduction of the lowest frequencies. The task of
designing our new TRUTH B2092A 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 theyve 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 youve
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: its you, our customers! Many satisfied customers
mean large sales volumes enabling us to get better purchasing
terms for components, etc. Isnt 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 TRUTH 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, its been worth the effort!
Thank you very much,
Uli Behringer
