5 EURORACK PRO RX1202FX User Manual
Introduction1.
With 8 phantom-powered microphone inputs as well as 4 high-headroom line
inputs, the RX1202FX comprises a total of 12 channels. All channels come with
60-mm faders and the extremely musical 2-band EQ, the clip LEDs, as well
as the 2 aux sends enable an uncompromising functionality of the console.
An integrated power supply guarantees optimal exibility through worldwide
independence of any mains connection. Additionally, it oers an absolutely
noiseless audio signal as well as an outstanding transient response by minimal
power consumption. With rst-class “Invisible“ Mic Preamps, the ultra-low
noise circuitry, the 24-bit eects processor as well as the separate control room,
headphones and CD/tape outputs, the RX1202FX has all the features that also
distinguish our UB mixers.
As sub-mixer, monitor mixer or as line mixer for audio/video installations,
the RX1202FX is the rst choice for demanding xed installations and mobile use.
IMP “INVISIBLE” MIC PREAMP
The microphone channels are tted with BEHRINGER’s premium quality
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 nest nuances
The extremely low-noise and distortion-free 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
They enable full utilization of the greatly extended dynamic range of your •
24-bit/192 kHz HD recorder, thereby main taining optimal audio quality.
MULTI-EFFECTS PROCESSOR
In addition, the RX1202FX oers an eects processor equipped with 24-bit
A/D and D/A converters. The FX processor puts at your disposal 100 presets
with rst-class room simulations, delay and modulation eects, and many
multi-eects in outstanding audio quality.
Caution!
We would like to inform you that high volume can damage your ◊
hearing and/or the headphones or loudspeakers. Before turning on
the device, please move the MAIN MIX fader of the main section all
the way down. Always take care to keep an appropriate volume level.
General mixing console functions 1.1
A mixing console fulls three main functions:
Signal processing: •
Preamplication
Microphones convert sound waves into voltage that has to be amplied
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 amplied 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 amplication
using an amplier 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 preamplication level could aect
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 eectively adjust the way a signal sounds.
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 ampliers, headphones as well as CD/tape
connectors are available here. The mix is sent to the internal FX processors or
external eects processors via aux sends and returns. Similarly, a mix can be
created for the musicians on the stage (monitor mix).
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/amplier).
The interface of BEHRINGER mixing consoles is optimized for these tasks,
enabling you to easily keep track of the signal path.
