5 EURORACK UB1204FX-PRO/UB1204-PRO User Manual
1. Introduction
The BEHRINGER EURORACK mixing console offers you premium-quality
microphone preamplifiers with optional phantom power supply, balanced line
inputs and the ability to connect external effects devices. Because of its extensive
and carefully thought-out routing possibilities, your EURORACK lends itself
equally to both live and studio use.
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:
• 130 dB dynamic range for an incredible amount of headroom
• A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear
reproduction of even the finest nuances
• The extremely low-noise and distortionless circuitry gua rantees absolutely
natural and transparent signal repro duction
• They are perfectly matched to every conceivable micro phone with up to
60 dB gain and +48 volt phantom power supply and
• They enable full utilisation of the greatly extended dynamic range of your
24-bit/192 kHz HD recorder, thereby main taining optimal audio quality
Additionally, your UB mixing console has an effects processor with 24-bit A/D
and D/A converters included, which gives you 100 presets producing first-class
reverb, delay and modulation effects plus numerous multi-effects in excellent
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 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 faders and phones 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:
• Signal processing: Preamplification, level adjustment, mixing of effects,
frequency equalization
• Signal 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
• Mix: 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, wehave arranged them in groups
according to their function. If you need to know more about specific issues,
please visit our website at http://behringer.com, where you’ll find explanations
of e.g. effects and dynamics applications.
◊ 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 aux send 1 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.
