EURORACK UB1222FX-PRO User Manual

1. Introduction

Congratulations! In purchasing the BEHRINGER EURORACK you have acquired a mixer whose small size belies its incredible versatility and audio performance.

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.

FBQ Feedback Detection System

The FBQ Feedback Detection System, integrated into the graphic equalizer, is one of the most outstanding characteristics of this mixing console. This ingenious circuitry lets you immediately recognize and eliminate feedback frequencies.

The FBQ Feedback Detection System uses the LEDs in the frequency band faders of the graphic EQ to indicate the critical frequencies. 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:

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 switchmode 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:

• 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.

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.

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.

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://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 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.

MIC

Each mono input channel offers a balanced microphone input via the XLR connector and also features a switchable +48 V phantom power supply for condenser microphones (see rear panel).

◊

Please mute your playback system before you activate the phantom power supply to prevent switch-on thumps being directed to your loud speakers. Please also note the instructions in chapter 2.5

“Rear view of UB1222FX-PRO”.

LINE IN

Each mono input also features a balanced line input on a 1/4" connector.

Unbalanced devices (mono jacks) can also be connected to these inputs.

◊

Please remember that you can only use either the microphone or the line input of a channel at any one time. You can never use both simultaneously!

INSERT

Insert points enable the processing of a signal with dynamic processors or equalizers. They are sourced pre-fader, pre-EQ and pre-aux send. Unlike reverb or other effects devices, whose signals are usually added to the dry signal, dynamic processors are most effective on the complete signal. In this case, aux send paths are a less-than-perfect solution. It is better to interrupt the signal path and insert a dynamic processor and/or equalizer. After processing, the signal is routed back to the console at precisely the same point it left.

However, the channel signal path is interrupted only if a plug is inserted into the corresponding jack (stereo phone plug: tip = signal output; ring = return input).

All mono input channels are equipped with inserts.

Inserts can also be used as pre-EQ direct outputs, without interrupting the signal path. To this end, you will need a cable fitted with mono phone plugs on the tape machine or effects device end, and a bridged stereo phone plug on the console side (tip and ring connected).

7

EURORACK UB1222FX-PRO User Manual

LOW CUT

The mono channels of the mixing consoles have a high-slope LOW CUT filter for eliminating unwanted, low-frequency signal components (80 Hz, 18 dB/octave).

TRIM

Use the TRIM control to adjust the input gain. This control should always be turned fully counter-clockwise whenever you connect or disconnect a signal source to one of the inputs.

The scale has 2 different value ranges: the first value range (+10 to +60 dB) refers to the MIC input and shows the amplification for the signals fed in there.

The second value range (+10 to -40 dBu) refers to the line input and shows its

sensitivity. The settings for equipment with standard line-level signals (-10 dBV or +4 dBu) look like this: While the TRIM control is turned all the way down, connect your equipment. Set the TRIM control to the external devices’ standard output level. If that unit has an output signal level display, it should show 0 dB during signal peaks. For +4 dBu, turn up TRIM slightly, for -10 dBV a bit more.

Tweaking is done using the LEVEL SET LED.

LEVEL SET

This LED lights up when the optimum operating signal level is achieved.

During normal use, this LED should only light up during signal peaks.

2.1.2 Equalizer

All mono input channels include a 3-band equalizer. All bands provide boost or cut of up to 15 dB. In the central position, the equalizer is inactive.

For situations that require effects processing, the aux sends are usually switched post-fader so that the effects volume in a channel corresponds to the position of the channel fader. If this were not the case, the effects signal of the channel would remain audible even when the fader is turned to zero.

When setting up a monitor mix, the aux sends are generally switched to pre-fader; i.e. they operate independently of the position of the channel fader.

Both aux sends are mono, are sourced after the equalizer and offer up to

+15 dB gain.

◊

If you press the MUTE switch of the respective channel, aux sends and returns (MON and FX) are not being muted.

MON

In the UB1222FX-PRO, aux send 1 (MON) is wired pre-fader and is thus particularly suitable for setting up monitor mixes.

FX

The aux send labeled FX is for feeding external effects devices and is thus set up to be post-fader.

In the UB1222FX-PRO, the FX send is routed directly to the built-in effects processor. To make sure that the effects processor receives an input signal, you shouldn’t turn this control all the way to the left (-∞). Don’t have the

FX MUTE switch pressed, and you should also not have the FX SEND fader pulled down.

2.1.4 Pan, mute switch and channel fader

Fig. 2.2: The equalizer of the input channels

The upper (HIGH) and the lower band (LOW) are shelving filters that increase or decrease all frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower band are 12 kHz and 80 Hz respectively.

The mid band is configured as a peak filter with a center frequency of 2.5 kHz.

Unlike shelving filters, the peak filter processes a frequency range that extends upwards and downwards around its middle frequency.

2.1.3 Aux sends (MON and FX)

Fig. 2.4: Channel fader and additional control elements

Fig. 2.3: The AUX SEND controls in the channel strips

Aux sends take signals via a control from one or more channels and sum these signals to a so-called bus. This bus signal is sent to an aux send connector and then routed, for example, to an active monitor speaker or an external effects device. The return from an external effects device can then be brought back into the console via the aux return connectors.

PAN

The PAN control determines the position of the channel signal within the stereo image. This control features a constant-power characteristic, which means the signal is always maintained at a constant level, irrespective of position in the stereo panorama.

MUTE

Use the MUTE switch to mute the channel. This means that the channel signal is no longer present in the main mix. However, the aux sends (MON and FX) remain active.

8

EURORACK UB1222FX-PRO User Manual

MUTE LED

The MUTE LED indicates that the relevant channel is muted.

CLIP LED

The CLIP LED lights up when the input signal is driven too high. In this case, lower apparent frequency increase on the channel EQ to avoid distortion.

For example, lower the mids and the highs somewhat to emphasize the bass.

If you don’t wish to change the EQ settings under any circumstances, try lowering the TRIM control somewhat (counterclockwise).

If you inserted an external effects processor via the insert connector

(e. g. a dynamic processor), then you should also control its output signal level.

It should not be higher than its input signal level (0 dB).

The channel fader determines the level of the channel signal in the main mix.

◊ Attention: Since the aux path for the effect processor is connected post-fader, the channel fader has to be turned up in order to get this channel’s signal to the effects processor!

2.2 Stereo channels

2.2.1 Channel inputs

2.2.3 Aux sends stereo channels

In principle, the aux sends of the stereo channels function in just the same way as those of the mono channels. As aux send paths are always mono, the signal on a stereo channel is first summed to mono before it reaches the aux bus.

2.2.4 Balance, mute switch and channel fader

BAL

The function of the BAL(ANCE) control corresponds to the PAN control in the mono channels.

The balance control determines the relative proportion between the left and right input signals before both signals are routed to the main stereo mix bus.

The MUTE switch, MUTE LED, CLIP LED and channel fader function in the same way as the mono channels.

2.3 Connector panel and main section

Whereas it was useful to trace the signal flow from top to bottom in order to gain an understanding of the channel strips, we now look at the mixing console from left to right. The signals are, so to speak, collected from one point on each of the channel strips and then routed to the main section all together.

Each stereo channel features two line-level inputs on 1/4" connectors for left and right channels. Channels 9/10 and 11/12 can also be used in mono if you only use the connector labeled “L.”

Both channels 5/6 and 7/8 feature an additional balanced XLR input for microphones with available +48 V phantom power.

All stereo channel strips have a TRIM control for level setting. In those channels in which a mic input is present in the channel, the TRIM control has two scales: just like in the mono channels, there is a 0 to +40 dB scale that shows the preamplification of the mic signal; the +20 to -20 dB scale shows the sensitivity for the corresponding input level that is applied to the line input.

Both inputs can also be used with balanced or unbalanced connectors.

2.2.2 Equalizer stereo channels

The equalizer of the stereo channels is, of course, stereo. The filter characteristics and crossover frequencies are the same as those of the mono channels. A stereo equalizer is always preferable to two mono equalizers if frequency correction of a stereo signal is needed. There is often a discrepancy between the settings of the left and the right channels when using separate equalizers.

MON SEND FX SEND

Fig. 2.6: Aux send controls of the main section

A channel signal is routed to the MON(ITOR) send bus if the MON control is turned up on the corresponding channel.

MON SEND

The aux send control MON SEND acts as master control for the monitor bus and determines the level of the summed signal that is taken from the mixer via the MON SEND connector and that can for example be fed to an amplifier for monitor purposes.

Using the audio signal from this output, you can also feed a subwoofer if you don’t require stage monitors. To this end, you should implement a crossover in your signal path pre-subwoofer and pre-amplifier, so that only low frequencies are fed into the subwoofer. You can achieve the same effect by using the built-in graphical equalizer. Lower all frequencies above 160 Hz and assign the equalizer to “Monitor”.

9

EURORACK UB1222FX-PRO User Manual

◊

When you use the MAIN MIX fader to reduce the overall volume, keep in mind that the subwoofer is still receiving a signal!

FX TO MON

You can use this control to insert an effects signal from the built-in effects processor to your monitor mix. Of course, to do this, your effects processor must first receive a signal, i.e. the FX controls in the channel strips must be turned up, and the FX SEND fader (see fig. 2.6) hast to be open.

MON MUTE

If the MON MUTE switch is pressed, the monitor bus is muted, i.e. there is no signal at the MON SEND connector.

FX SEND

The FX SEND fader determines the overall level of the effects bus. Both external effects processors (via the FX SEND connector) and the built-in processor only receive an input signal if this control is open.

FX TO MAIN

Use the FX TO MAIN control to feed the effects signal into the main mix. If the control is turned all the way to the left, no effects signal can be heard.

FX MUTE

If the FX MUTE switch is pressed, the effects channel is muted, i.e. no signal is present at the FX SEND connector and the effects processor no longer receives an input signal.

AUX RETURN 1

The AUX RETURN 1 connectors generally serve as the return path for the effects mix generated using the FX send. This is where you connect the output signal of the external effects device. If only the left connector is used, the aux return

1 automatically operates in mono.

◊ You can also use these connectors as additional line inputs.

AUX RETURN 2

The AUX RETURN 2 connectors are used exactly the same way as the AUX RETURN

1 connectors. If these connectors already function as additional inputs, you can route the effects signal back into the console via a different stereo channel, with the added benefit that the channel EQ can be used to adjust the frequency response of the effects return signal.

◊

In this instance, the FX control of the channel being used as an effects return should be turned fully counter-clockwise, otherwise feedback problems can occur!

SEND

Fig. 2.7: Aux send connectors MON and FX

MON SEND

Connect the input of your monitor power amp or an active monitor system here to make the monitor mix audible to the musicians on the stage. The signal mix is created using the channels’ MON controls.

FX SEND

The FX SEND connector outputs the signal you picked up from the individual channels using the FX controls. You can connect this to the input of an external effects device in order to process the FX bus’ master signal. Once an effects mix is created, the processed signal can then be routed from the effects device outputs back into the AUX RETURN connectors.

◊

◊

If the connected effects processor receives no input signal, the FX MUTE switch is probably pressed and/or the FX SEND control is too low. This also goes for the built-in effects processor.

Adjust your external effects processor to 100% wet (effects signal only), because the effects signal is added to the main mix along with the “dry” channel signals.

Fig. 2.9: 2-Track return channel

This channel, intended especially for connecting stereo signal sources

(CD players, DAT recorders or even sound cards) features a particularly practical feature: the VOICE CANCELLER.

VOICE CANCELLER

Here, you have a filter circuitry that lets you almost entirely remove the vocal portion of a recording. The filter is constructed in such a way that voice frequencies are targeted without majorly affecting the rest of the signal.

Additionally, the filter seizes only the middle of the stereo image, exactly there where the vocals are typically located.

10

EURORACK UB1222FX-PRO User Manual

Possible applications for the Voice Canceller are obvious: you can very simply stage background music for Karaoke events. Of course, you can also do this at home or at your rehearsal room before you hit the stage. Singers with their own band can practice singing difficult parts using a complete playback from a tape player or a CD, thus minimizing rehearsal time.

STANDBY

If the STANDBY switch is pressed, all input channels with a mic connector

(XLR connector) are muted. During breaks or stage conversion, you can prevent noise from entering the sound system via the microphones. Such noise can in the worst-case scenario even irreparably damage loudspeaker membranes. The cool thing about this is that the main mix faders can remain open, so that you can play music from a CD at the same time. Similarly, the faders for the muted channels can also remain in their position.

To bring in other sound sources, you can use the 2-track inputs, stereo input channels 9 to 12 and the aux return inputs.

2-TRACK MUTE

Using this switch, the input signal from the 2-track inputs is muted.

2-TRACK INPUT

The 2-TRACK INPUT RCA connectors are provided for connecting a 2-track machine (e.g. DAT recorder) or also a CD player. They can also be used as stereo line input. Alternatively, the output signal of a second EURORACK or BEHRINGER

ULTRALINK PRO MX882 can also be connected. If you connect a hi-fi amplifier with a source selection switch to the 2-TRACK INPUT, you can easily switch between additional sources (e.g. cassette recorder, MD player, sound card etc.).

Using the voice canceller function, you can process all signals being brought into your mixing console via these connectors.

2-TRACK OUTPUT

These connectors are wired pre graphic EQ and pre XPQ surround function.

They carry the main mix signal (unbalanced), effects mix included. Connect the

2-TRACK OUTPUT to the inputs of your recording device. If you wish to use your mixer solely for recording purposes, the main outputs are also an alternative.

Fig. 2.12: Main out connectors

MAIN OUT

The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors with a nominal level of +4 dBu. Depending on how you wish to use your mixer and which gear you own, you can connect the following equipment:

Live PA systems:

A stereo dynamics processor (optional), stereo equalizer (optional) and the stereo power amplifier for full-range loud-speakers with passive crossovers.

If you wish to use multi-way loudspeaker systems without an integrated crossover, you have to use an active crossover and several power amplifiers.

Often, limiters are already built into active crossovers (e.g. BEHRINGER SUPER-X

PRO CX2310 and ULTRADRIVE PRO DCX2496). Active crossovers are implemented directly before the power amplifier, and they divide the frequency range into several segments that are first amplified in the amplifiers and then passed onto the corresponding loudspeakers.

Recording:

For mastering, using a stereo compressor such as the COMPOSER PRO-XL

MDX2600 can be recommended. Use it to custom-tailor the dynamic characteristics of your signal to the dynamic range of the recording equipment you are using. The signal is in this case passed on from the compressor into the recorder.

PHONES

The PHONES control adjusts the volume of the headphones connected to the

PHONES/CTRL connector. If you connect active monitors or an amplifier, use this connector to adjust the output signal level.

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 PHONES control in the main section fully down before you switch on the unit. Always be careful to set the appropriate volume.

LEVEL METER/CLIP

The high-precision level meter accurately displays the appropriate signal level.

LEVEL SETTING:

When recording to a digital device, the recorder’s peak meter should not exceed

0 dB. This is because, unlike analog recordings, slightly excessive levels can create unpleasant digital distortion.

When recording to an analog device, the VU meters of the recording machine should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to their inertia VU meters tend to display too low a signal level at frequencies above

1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10 dB.

Snare drums should be driven to approx. 0 dB.

◊

The peak meters of your EURORACK display the level virtually independent of frequency. A recording level of 0 dB is recommended for all signal types.

2.4 Graphic 7-band equalizer

PHONES/CTRL connector

You can connect headphones to this 1/4" TRS connector. The connector can also be used for feeding active monitor loudspeakers (or an amplifier) in your control room. For this purpose, the signal is taken directly before it is passed on to the main mix faders.

FBQ FEEDBACK DETECTION

The switch turns on the FBQ Feedback Detection System. It uses the LEDs in the frequency band faders to indicate the critical frequencies. On a per-need basis, lower the frequency range in question somewhat in order to avoid feedback.

The graphic stereo equalizer has to be turned on in order to use this function.

◊

Logically, at least one (ideally several) microphone channels have to be open for feedback to occur at all!

Feedback is particularly common when stage monitors (“wedges”) are concerned, because monitors project sound in the direction of microphones.

Therefore, you can also use the FBQ Feedback Detection for monitors by placing the equalizer in the monitor bus (see MAIN MIX/MONITOR).

EQ IN

Use this switch to activate the graphic equalizer. When activated, the fader LEDs will illuminate.

MAIN MIX/MONITOR

This toggles the graphic equalizer between the main mix and the monitor mix.

With the switch up (not depressed), the equalizer is active in stereo on the main mix, and inactive on the monitor mix.

When the switch is depressed the equalizer is active in mono on the monitor mix, and inactive on the main mix.

FUSE HOLDER/IEC MAINS RECEPTACLE

The console is connected to the mains via the cable supplied, which meets the required safety standards. Blown fuses must only be replaced by fuses of the same type and rating. The mains connection is made via a cable with IEC mains connector. An appropriate mains cable is supplied with the equipment.

POWER

Use the POWER switch to power up the mixing console. The POWER switch should always be in the “Off” position when you are about to connect your unit to the mains.

To disconnect the unit from the mains, pull out the main cord plug.

When installing the product, ensure that the plug is easily accessible. If mounting in a rack, ensure that the mains can be easily disconnected by a plug pull or by an all-pole disconnect switch on or near the rack.

◊

Attention: The POWER switch does not fully disconnect the unit from the mains. Unplug the power cord completely when the unit is not used for prolonged periods of time.

PHANTOM

The PHANTOM switch activates the phantom power supply for the XLR microphone inputs, which is required to operate condenser microphones.

The red +48 V LED lights up when phantom power is on. As a rule, dynamic microphones can still be used with phantom power switched on, provided that they are wired in a balanced configuration. In case of doubt, contact the microphone manufacturer!

24-BIT MULTI-EFFECTS PROCESSOR

Here you can find a list of all presets stored in the multi-effects processor.

This built-in effects module produces high-grade standard effects such as reverb, chorus, flanger, delay and various combination effects. The integrated effects module has the advantage of requiring no wiring. This way, the danger of creating ground loops or uneven signal levels is eliminated at the outset, completely simplifying the handling.

These effect presets are designed to be added to dry signals. If you move the

FX TO MAIN control, you mix the channel signal (dry) and the effect signal.

This also goes for mixing effects signals with the monitor mix. The main difference is that the mix ratio is adjusted using the FX TO MON control. Of course, a signal has to be fed into the effects processor via the FX control in the channel strip for both applications.

◊

Turn down the FX controls in those channel strips whose signals you don’t wish to process.

The surround function can be enabled/disabled with the XPQ TO MAIN switch.

This is a built-in effect that widens the stereo width, thus making the sound more lively and transparent. Use the SURROUND control to determine the intensity of this effect.

4.2.1 Audio connections

Please use commercial RCA cables to wire the 2-track inputs and outputs.

You can, of course, also connect unbalanced devices to the balanced input/outputs. Use either mono plugs, or ensure that ring and sleeve are bridged inside the stereo plug (or pins 1 & 3 in the case of XLR connectors).

4. Installation

4.1 Rack mounting

The packaging of your mixing console contains two 19" rack mount brackets which can be installed on the side panels of the console.

Before you can attach the rack mount brackets to the mixing console, you need to remove the screws holding the left and right side panels. Use these screws to fasten the two brackets onto the console, being careful to note that each bracket fits a specific side. With the rack mount brackets installed, you can mount the mixing console in a commercially available 19" rack. Be sure to allow for proper air flow around the unit, and do not place the mixing console close to radiators or power amps, so as to avoid overheating.

◊

Only use the screws holding the mixing console side panels to fasten the 19" rack mounts.

4.2 Cable connections

You will need a large number of cables for the various connections to and from the console. The following illustrations show the wiring of these cables. Be sure to use only high-grade cables.
