-PRO
This way, what once used to be a labor-intensive search for
feedback frequencies is now an activity that even a child could
master.
IMP “INVISIBLE” MIC PREAMP
The microphone channels are fitted with BEHRINGER’s brand
new high-end IMP INVISIBLE MIC PREAMPs that boast the
following features:
s 130 dB dynamic range for an incredible amount of headroom,
s a bandwidth ranging from below 10 Hz to over 200 kHz for
crystal-clear reproduction of even the finest nuances,
s the extremely low-noise and distortionless circuitry gua-
rantees absolutely natural and transparent signal repro-
duction,
s they are perfectly matched to every conceivable micro-
phone with up to 60 dB gain and +48 volt phantom power
supply and
s they enable full utilisation of the greatly extended dynamic
range of your 24-bit/192 kHz HD recorder, thereby main-
taining optimal audio quality.
In addition, the BEHRINGER UB1222FX-PRO offers an effects
processor equipped with 24-bit A/D and D/A converters. The
processor is fitted with the effect algorithms from our tried and
tested 19" multi-effects device, the VIRTUALIZER PRO DSP2024P.
99 presets are available providing first-class room simulations,
delay and modulation effects, as well as compression, tube
distortion and many other effects, all with stunning audio quality.
The mixing consoles of the PRO series feature a state of the
art, integrated switch-mode power supply. One of the great
advantages is that (compared to conventional circuits) a switch-
mode power supply adapts to mains voltages between 100 and
240 volts automatically. Furthermore, due to its much greater
efficiency, it consumes much less energy than a conventional
power supply unit.
CAUTION!
+
We would 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 faders and the PHIONES control in the main
section fully down before you switch on the unit.
Always be careful to set the appropriate volume.
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 ( D irect I njection) 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.
Effects mixing
In addition to the effects processor contained in your mixer,
using the insert connectors on the mono channels and
both aux busses lets you insert additional signal processors
into your signal path.
s Signal distribution :
Individual signals adjusted at each channel strip are laid
out at the aux sends and returns, and are either fed into
external effects processors or fed back to the internal
effects processor. Then, the signals are brought back into
the main mix either via the aux return connectors or via
direct internal wiring. The mix for the on-stage musicians is
also created using the aux sends (monitor mix). Similarly,
for example, signals for recording equipment, power ampli-
fiers, headphones and 2-track outputs can also be taken.
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, you’ll 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.
1.2 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. 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 in the ULTRANET 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 MON SEND connector. Don’t be put off
by the huge range of possibilities; it’s easier than you think! If you
look at the overview of the controls at the same time, you’ll be
able to quickly familiarize yourself with your mixing console and
you’ll 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, which 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.
