FOREWORD
Dear Customer,
welcome to the team of
BEHRINGER users, and
thank you very much for
expressing your confi-
dence in us by purchasing
the POWERPLAY PRO.
Writing this foreword for
you gives me great
pleasure, because it re-
presents the culmination
of many months of hard
work delivered by our
engineering team to
achieve a very ambitious
goal: to present two out-
standing pieces of
equipment, whose flexi-
bility lets them find use
in both studios and
P.A. situations.
The task of designing our new POWERPLAY 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 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 (manufactured under ISO9000 certified management
system) 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
POWERPLAY 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, its been worth the effort!
Thank you very much,
Uli Behringer
1. INTRODUCTION
Congratulations! With the BEHRINGER POWERPLAY PRO,
you have acquired a high-end headphone amplifier. Both
POWERPLAY PRO units were developed with the most de-
manding applications in mind: professional recording, radio and
television studios, as well as CD/digital sound production. They
were developed as benchmark units for judging mixdown quality
as well as distribution amplifiers for flexible playback appli-
cations in studio environments.
Balanced inputs and outputs
Both BEHRINGER POWERPLAY PROs feature electronically
servo-balanced inputs and outputs. The servo function auto-
matically recognizes when unbalanced pins are assigned. It
internally modifies the nominal signal level, thus preventing any
occurence of signal level difference between inputs and outputs
(6 dB correction).
+ 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 at a safe place for future
reference.
1.1 Before you get started
The POWERPLAY PRO was carefully packed at the assembly
plant to assure secure transport. Should the condition of the
cardboard box suggest that damage may have taken place, please
inspect the unit immediately and look for physical indications of
damage.
+ Damaged units should NEVER be sent directly to us.
Please inform the dealer from whom you acquired the
unit immediately as well as the transportation company
from which you took delivery of the unit. Otherwise, all
claims for replacement/repair may be rendered invalid.
