5EURORACK PRO RX1202FX User Manual

1.Introduction

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 flexibility through worldwide independence of any mains connection. Additionally, it offers an absolutely noiseless audio signal as well as an outstanding transient response by minimal power consumption. With first-class “Invisible“ Mic Preamps, the ultra-low noise circuitry, the 24-bit effects 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 first choice for demanding fixed installations and mobile use.

IMP “INVISIBLE” MIC PREAMP

The microphone channels are fitted 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 finest nuances

•The extremely low-noise and distortion-free circuitry guarantees­ absolutely natural and transparent signal reproduction­

•They are perfectly matched to every conceivable microphone­ 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 maintaining­ optimal audio quality.

MULTI-EFFECTS PROCESSOR

In addition, the RX1202FX offers an effects processor equipped with 24-bit A/D and D/A converters. The FX processor puts at your disposal 100 presets with first-class room simulations, delay and modulation effects, and many multi-effects 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.

1.1 General mixing console functions

A mixing console fulfils three main functions:

•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 microphone­ 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.

•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).

•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.
