EURORACK UB1002FX/UB1202FX
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 counterclockwise 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:
s Signal processing:
Preamplification
Microphones convert sound waves into voltage that has
to be amplified several-fold; then, this voltage is turned into
sound that is reproduced in a loudspeaker. Because micro-
phone capsules are very delicate in their construction,
output voltage is very low and therefore susceptible to
interference. Therefore, mic signal voltage is amplified
directly at the mixer input to a higher signal level that is less
prone to interference. This higher, interference-safe signal
level has to be achieved through amplification using an
amplifier of the highest quality in order to amplify the signal
and add as little noise to it as possible. The IMP Invisible
Mic Preamp performs this role beautifully, leaving no traces
of noise or sound coloration. Interference that could take
place at the preamplification level could affect signal quality
and purity, and would then be passed on to all other
devices, resulting in inaccurate sounding program during
recording or playback.
Level-setting
Signals fed into the mixer using a DI-box (Direct Injection) or
the output of a sound card or a keyboard, often have to be
adjusted to the operating level of your mixing console.
Frequency response correction
Using the equalizers found in each channel strip, you can
simply, quickly and effectively adjust the way a signal
sounds.
s Signal distribution:
Individual, processed signals from the channel strips are
compiled on busses and are fed into the main section for
further processing. Connections for recording equipment,
power amplifiers, headphones as well as CD/tape
connectors are available here. The mix is sent to the internal
FX processors or external effects processors via aux
sends and returns. Similarly, a mix can be created for the
musicians on the stage (monitor mix).
s Mix:
All other mixing console functions fall under this vital
category. Creating a mix means primarily adjusting the
volume levels of individual instruments and voices to one
another as well as giving them the appropriate weight within
the overall frequency spectrum. Likewise, youll have to
sensibly spread individual voices across the stereo image
of a signal. At the end of this process, adjusting the level of
the entire mix to other equipment in the signal path is required
(e. g. recorder/crossover/amplifier).
The interface of BEHRINGER mixing consoles is optimized for
these tasks, enabling you to easily keep track of the signal path.
1. INTRODUCTION
1.2 The users manual
The users 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. If
you need to know more about specific issues, please visit our
website at http://www.behringer.com. Additional information and
explanations about various music industry/audio technology
terminology can be found on individual product pages as well as
in the glossary area of www.behringer.com.
+ 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.
For the moment, just try and trace the signal path from the
microphone input to the FX SEND connector. Dont be put off by
the huge range of possibilities; its easier than you think! If you
look at the overview of the controls at the same time, youll be
able to quickly familiarize yourself with your mixing console and
youll soon be making the most of all its many possibilities.
1.3 Before you get started
1.3.1 Shipment
Your mixing console was carefully packed in the factory to
guarantee safe transport. Nevertheless, we recommend that
you carefully examine the packaging and its contents for any
signs of physical damage that may have occurred during transit.
+ If the unit is damaged, please do NOT return it to us,
but notify your dealer and the shipping company
immediately, otherwise claims for damage or
replacement may not be granted.
+ To assure optimal protection of your EURORACK
during use or transport, we recommend utilizing a
carrying case.
+ Please always use the original packaging to avoid
damage due to storage or shipping.
+ Never let unsupervised children play with the
EURORACK or with its packaging.
+ Please dispose of all packaging materials in an
environmentally-friendly fashion.
1.3.2 Initial operation
Be sure that there is enough space around the unit for cooling
purposes and to avoid overheating please do not place your
mixing console on high-temperature equipment such as radiators
or power amps.
+ Never connect the EURORACK to the power supply
unit when the latter is connected to the mains!
First connect the power supply unit to the console,
then connect the power supply unit to the mains.
+ Please make sure that all units have a proper
ground connection. For your own safety, never
remove or disable the ground conductor from the
unit or on the AC power cord. The unit should always
be connected to a mains socket outlet with a
protective earthing connection.
+ When installing the product, ensure the appliance
coupler or power cord is easily accessible for
disconnecting the unit from mains.
