1. INTRODUCTION

Congratulations! In purchasing our EURORACK UB502/UB802/
UB1002/UB1202 you have acquired a mixing console whose
small size belies its incredible versatility and audio performance.
The range of inputs and outputs comprises microphone inputs
(with +48 V phantom power supply, except UB502), line inputs,
possibilities for connecting effects devices, connectors for a 2-
track master machine (e.g. DAT recorder) and a monitor system
consisting of monitor loudspeaker(s) and power amplifier (except
for UB502).
IMP INVISIBLE MIC PREAMP
The microphone channels are fitted with BEHRINGERs brand
new premium quality IMP INVISIBLE MIC PREAMPs that boast the
following features:
s130 dB dynamic range for an incredible amount of headroom
sA bandwidth ranging from below 10 Hz to over 200 kHz for
crystal-clear reproduction of even the finest nuances
sThe extremely low-noise and distortionfree circuitry gua-
rantees absolutely natural and transparent signal repro-
duction
sThey are perfectly matched to every conceivable micro-
phone with up to 60 dB gain and +48 volt phantom power
supply (UB502: no phantom power)
sThey enable full utilisation of the greatly extended dynamic
range of your 24-bit/192 kHz HD recorder, thereby main-
taining optimal audio quality

CAUTION!

+We should like to draw your attention to the fact
that extreme volumes may damage your hearing
and/or your headphones or loudspeakers. Turn the
MAIN MIX control and PHONES control in the main
section fully counter-clockwise before you switch
on the unit. Always be careful to set appropriate
volume levels.

1.1 General mixing console functions

A mixing console fulfils three main functions:
sSignal processing: Preamplification, level adjustment,
mixing of effects, frequency equalization.
sSignal distribution: Summing of signals to the aux sends
for effects processing and monitor mix, distribution to one
or several recording tracks, power amp(s), control room
and 2-track outputs.
sMix: Setting the volume level, frequency distribution and
positioning of the individual signals in the stereo field, level
control of the total mix to match the recording devices/
crossover/power amplifier(s). All other mixer functions can
be included in this main function.
The interface of BEHRINGER mixing consoles is optimized for
these tasks enabling you to easily keep track of the signal path.

1.2 The users manual

The users manual is designed to give you both an overview of
the controls, as well as detailed information on how to use them.
In order to help you understand the links between the controls,
we have arranged them in groups according to their function.
The illustrations at the beginning of each chapter show the
controls described in each respective chapter.
+The block diagram supplied with the mixing console
gives you an overview of the connections between
the inputs and outputs, as well as the associated
switches and controls.

FOREWORD

Dear Customer,
Im sure youre one of
those people who have
devoted themselves body
and soul to your chosen
area and no doubt this has
transformed you into an
expert in your field!
Well, for over 30 years,
my passion has been
music and electronics.
This not only led me to
establish BEHRINGER,
but also enabled me to
convey and share my
enthusiasm with my
employees.
During all the years Ive
been involved with
studio technology and
end users, I have developed a feel for the things that really
count, such as sound quality, reliability and ease of use. Whats
more, I have always had the desire to push the boundaries of
technical possibilities to the extreme.
It was precisely this motivation that prompted me to start work
on a new series of mixing consoles. Since our EURORACKs had
already set new standards world-wide, I knew the development
objectives behind the products bearing my initials had to be
especially ambitious.
Thus, the concept and design of the new UB mixing consoles
bear my signature. The design work, the entire circuit diagram
and PCB development, and even the mechanical concepts are
my own work. I carefully selected each individual component
with the aim of pushing the mixing consoles analog and digital
technologies to their limits.
My vision was to enable you, the user, to give free rein to your
true potential and creativity. The result is incredibly powerful mixing
consoles that offer intuitive operation. They cannot fail to impress
with their extremely flexible routing possibilities plus fantastic wealth
of functions. Innovative technologies, such as the completely new
IMP Invisible Mic Preamps, guarantee optimum sound quality.
And extraordinarily high-quality components provide unrivalled
reliability, even under extreme loads.
Your new UB mixing console is of high quality yet is simple to
use; youll soon appreciate that I, both personally and in my
capacity as musician and sound engineer, put you, the end user,
first and that these products were only possible because of the
passion and the attention to detail that went into them.
Thank you for the confidence you have placed in us by
purchasing the UB mixing console. I should also like to thank all
those who, with their personal commitment and passion, have
helped me realize this impressive series of mixing consoles.
Kindest regards,
Uli Behringer
