EURORACK UB1622FX-PRO/UB1832FX-PRO/UB2222FX-PRO/UB2442FX-PRO FOREWORD
Dear Customer, Im sure youre one of those people who have devoted themselves body and soul to your chosen area and no doubt this has transformed you into an expert in your field! Well, for over 30 years, my passion has been music and electronics. This not only led me to establish BEHRINGER, but also enabled me to convey and share my enthusiasm with my employees. During all the years Ive been involved with studio technology and end users, I have developed a feel for the things that really count, such as sound quality, reliability and ease of use. Whats more, I have always had the desire to push the boundaries of technical possibilities to the extreme. It was precisely this motivation that prompted me to start work on a new series of mixing consoles. Since our EURORACKs had already set new standards world-wide, I knew the development objectives behind the products bearing my initials had to be especially ambitious. Thus, the concept and design of the new UB mixing consoles bear my signature. The design work, the entire circuit diagram and PCB development, and even the mechanical concepts are my own work. I carefully selected each individual component with the aim of pushing the mixing consoles analog and digital technologies to their limits. My vision was to enable you, the user, to give free rein to your true potential and creativity. The result is incredibly powerful mixing consoles that offer intuitive operation. They cannot fail to impress with their extremely flexible routing possibilities plus fantastic wealth of functions. Innovative technologies, such as the completely new IMP Invisible Mic Preamps, guarantee optimum sound quality. And extraordinarily high-quality components provide unrivalled reliability, even under extreme loads. Your new UB mixing console is of high quality yet is simple to use; youll soon appreciate that I, both personally and in my capacity as musician and sound engineer, put you, the end user, first and that these products were only possible because of the passion and the attention to detail that went into them. Thank you for the confidence you have placed in us by purchasing the UB mixing console. I should also like to thank all those who, with their personal commitment and passion, have helped me realize this impressive series of mixing consoles.

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 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. 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 amplifiers, 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, youll 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 control surface of BEHRINGER mixing consoles is optimized in such a way that these functions become easy to fulfil while the signal path remains simple to follow.

Multi-effects processor Additionally, your EURORACK 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. FBQ Feedback Detection System The FBQ Feedback Detection System integrated into the graphic EQ of your UB1832FX-PRO is one of this mixers most outstanding features. 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. Voice Canceller We have added another useful feature to the EURORACK UB1832FX-PRO: the Voice Canceller. The Voice Canceller is a filter circuitry that filters out vocal portions from a track. Therefore, this mixing console is ideally suited for use as a karaoke machine. This feature is also an optimal solution for singers who need accompanying music for their rehearsals.

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

Please remember that you can use either the microphone input or the line input of a channel, but not both at the same time!
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. Detailed information on using insert points can be found in chapter 5.3.
Unlike the UB2442FX-PRO, the UB1622FX-PRO, UB1832FX-PRO and UB2222FX-PRO have their insert points located on the rear of the console.
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 dB) refers to the line input and shows its sensitivity. The settings for equipment with st andard 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 +4dBu, turn up TRIM slightly, for -10 dBV a bit more. Fine-tuning of a signal being fed in is done using the level meter. To route the channel signal to the level meter, you have to press the SOLO switch and set the MODE switch in the main section to PFL (LEVEL SET). Using the TRIM control, drive the signal to the 0-dB mark. This way you have a vast amount of drive headroom for use with very dynamic signals. The CLIP display should light up only rarely, preferably never. While fine-tuning, the equalizer should be set to neutral. LOW CUT Additionally, the mono channels of the mixing consoles have a high-slope LOW CUT filter for eliminating unwanted, lowfrequency signal components (75 Hz, 18 dB/octave). routed, for example, to an active monitor speaker or external effects device. In the latter case, the effects return can then be brought back into the console via the aux return connectors. All monitor and effects busses are mono, are tapped into post EQ and offer amplification of up to +15 dB. Pre-fader/post-fader When using effects on a channel signal, it is usual to have the aux send post fader so that the balance between effect and dry signal stays constant even when the channel fader is altered. If this were not the case, the effects signal of the channel would remain audible even when the channel fader is turned all the way down. For monitoring, the aux sends are generally pre-fader, i.e. they operate independently of the position of the channel fader. PRE When the PRE switch is pressed down, the associated aux send is taken pre-fader. FX The aux send marked FX offers a direct route to the built-in effects processor and is therefore post-fader and post-mute. Please refer to chapter 4 DIGITAL EFFECTS PROCESSOR for detailed information.

2.1.2 Equalizer

All mono input channels have a 3-band equalizer with semiparametric mid bands. All bands provide boost or cut of up to 15 dB. In the central position, the equalizer is off (flat).
If you are using the built-in effects processor, make sure that STEREO AUX RETURN 3 has nothing plugged into it (UB2442FX-PRO and UB2222FX-PRO), otherwise the internal effects return will be muted. This is not relevant if you use the FX OUT jack to drive an external effects device. UB1622FX-PRO and UB1832FX-PRO: On these consoles, the above note refers to the STEREO AUX RETURN 2 jacks as these models do not have a dedicated effect output.
2.1.4 Routing switch, PAN, SOLO and channel fader
Fig. 2.2: Equalizer of the input channels The upper (HIGH) and the lower (LOW) bands 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 bands are 12 kHz and 80Hz respectively. For the mid range, the console features a semi-parametric equalizer with a filter quality (Q) of 1 octave, tunable from 100 Hz to 8 kHz. Use the MID control to set the amount of boost or cut, and the FREQ control to determine the central frequency.
2.1.3 Monitor and effects busses (Aux sends)
Fig. 2.4: The panorama and routing controls and the channel fader PAN The PAN control determines the position of the channel signal within the stereo image. When working with subgroups, you can use the PAN control to assign the signal to just one output, which gives you additional flexibility in recording situations. For example, when routing to subgroups 3 and 4, panning hard left will route the signal to group output 3 only, and panning hard right will route to group output 4 only. MUTE The MUTE switch breaks the signal path pre-channel fader, hence muting that channel in the main mix. The aux sends which are set to post-fader are likewise muted for that channel, while
Fig. 2.3: Aux Send control MON and FX in the channel strips Monitor and effects busses (AUX sends) source their 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 (for monitoring applications: MON OUT) and then

the pre-fader monitor paths remain active irrespective of whether the channel is muted or not. MUTE LED The MUTE LED indicates a muted channel. CLIP-LED The CLIP-LED lights up when the input signal is driven too high. If this happens, back off the TRIM control and, if necessary, check the setting of the channel EQ. SOLO The SOLO switch is used to route the channel signal to the solo bus (Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to listen to a channel signal without affecting the main output signal. The signal you hear is taken either before the pan control (PFL, mono) or after the pan and channel fader (Solo, stereo) (cf. chap. 2.3.10 Level meters and monitoring). SUB (1-2 and 3-4) The SUB switch routes the signal to the corresponding subgroups. The UB2442FX-PRO has 4 subgroups (1-2 and 3-4). MAIN The MAIN switch routes the signal to the main mix bus. The channel fader determines the channels volume in the main mix (or submix). Fig. 2.6: Balance control and mute switch BAL The BAL(ANCE) control has a similar function to the PAN control in the mono channels. The balance control determines the levels of the left and right input signals relative to each other before both signals are routed to the left/right main mix bus (or odd/even subgroup). The remaining control elements in the stereo channels perform the same functions as their counterparts in the mono channels (MUTE switch, MUTE and CLIP LEDs, SOLO switch, SUB and MAIN switches and channel fader).
2.2.2 Equalizer stereo channels
The stereo channels contain a stereo EQ section. The cut-off frequencies of the high and low bands are 12 kHz and 80 Hz respectively, while the center frequencies of the high-mid and low-mid bands are 3 kHz and 500 Hz respectively. The HIGH and LOW controls have the same characteristics as the EQ in the mono channels. Both mid range bands are of the peak filter type. A stereo EQ is superior to two mono EQs on a stereo signal as two separate EQs will usually result in a discrepancy between left and right channels.
2.2.3 Aux sends stereo channels
In principle, the aux sends of the stereo channels function the same way as those of the mono channels. As the aux sends are mono, the send from a stereo channel is first summed to mono before it reaches the aux bus.
2.2.4 Routing switch, solo and channel fader

2.2 Stereo channels

2.2.1 Channel inputs
2.3 Interface panel and main section
Where 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 the same point on each of the channel strips and then routed to the main section all together.
2.3.1 MON control, aux sends 1, 2 and 3 (FX)

You can also use these jacks as additional line inputs.
If you want to monitor the signal of just one AUX bus, none of the other SOLO SWITCHES should be pressed and the MODE switch should be in the SOLO position (not depressed).
All stereo aux returns are balanced, but can of course also be used with unbalanced connectors. If you use an aux send for monitoring, the associated unused stereo aux returns are available for other line level signals (e.g. keyboards).

2.3.2 Aux send jacks

A signal fed into the stereo return jacks can be output via an aux send jack. More information on this can be found in chapter 2.3.5 STEREO AUX RETURN 1/2 (TO AUX SEND).
STEREO AUX RETURN FX The STEREO AUX RETURN FX jacks accept the effects mix return (created using the channel FX sends). If these jacks are already in use as additional inputs, you can route the effects signal back into the console via a different channel. The advantage of this is that you can now use that channels EQ on the effects return signal. Fig. 2.8: Aux send jacks AUX SEND jacks The AUX SEND jack should be used when hooking up a monitor power amp or active monitor speaker system. The relevant aux path should be set pre-fader.
In this instance, the FX control of the channel being used as an effects return should be turned fully counterclockwise, otherwise feedback problems could occur! If you wish to use the internal effects processor, do not plug any connectors into the STEREO AUX RETURN FX jacks, unless you want to tap the processed signal via the FX OUT (UB2222FX-PRO and UB2442FX-PRO only).
On the UB2222FX-PRO, aux send 1 is hard wired as pre-fader and hence called MON. Model UB1832FX-PRO has a dedicated monitor output (MON OUT jack), cf. chapter 2.3.4.
As already mentioned, the aux sends in the channelsif set post-fadercan be used to connect to external effects devices. AUX SEND (FX) The AUX SEND (FX) jack carries the master aux mix (from the channels FX controls). You can connect this to an external effects device to process the FX bus. The processed signal can then be brought from the effects device back into the STEREO AUX RETURN jacks.
2.3.4 The monitor section of the UB1832FX-PRO
One of the ways that the UB1832FX-PRO differs from the other models of this series is that it has a separate monitor output.
Fig. 2.10: Monitor output of the UB1832FX-PRO The first aux send (MON) on this console is used to set up the monitor mix from the channels and route it to the MON SEND fader.
Using the STEREO AUX RETURN (TO AUX SEND) control, the effect signal can now be blended into the monitor mix. You can easily use the headphones distribution amplifier BEHRINGER POWERPLAY PRO HA4700/HA8000 to provide four (HA8000: eight) stereo headphone mixes for your studio. The following table shows which jacks on the console can be used for this purpose.

SOLO RETURNS Additionally, this model allows you to route the aux returns together to the solo bus and the PFL bus. The LED lights up when Solo is on. STEREO AUX RETURN 4 (UB2442FX-PRO only) This control behaves the same way as the other stereo aux returns. Additionally, it provides for a simple monitor path using the switch CTRL ROOM & PHONES ONLY. CTRL ROOM & PHONES ONLY Use this switch to route the signal appearing at the AUX RETURN 4 jacks to the control room and headphones outputs.
2.3.6 Supplement to UB1832FX-PRO
The UB1832FX-PRO has a stereo fader for the AUX RETURN FX and offers a variety of routing options: MUTE disables the effect return (but not PFL of course!), SOLO routes it to the Solo or PFL busses, SUB to the subgroups and MAIN to the main mix.
2.3.8 CD/Tape input, CD/tape output
Fig. 2.15: 2-track connectors and lamp socket CD/TAPE INPUT The CD/TAPE INPUT jacks (RCA) are designed to accept a 2-track recorder (e.g. DAT recorder), or they can be used as stereo line input. The output signal of a second EURORACK or the BEHRINGER ULTRALINK PRO MX882 can also be connected here. If you connect the output of a hi-fi amplifier (with a source selection switch) to the CD/TAPE INPUT, you can easily listen to additional sources (e.g. cassette recorder, MDplayer, sound card, etc.). Using the voice canceller function (UB1832FX-PRO only), you can process all signals being brought into your mixing console via these connectors. CD/TAPE OUTPUT These connectors are wired in parallel to the MAIN OUT and carry the main mix signal (unbalanced). Connect this to the inputs of your recording device. The final output level can be adjusted via the high-precision MAIN MIX fader.
Fig. 2.13: The FX/AUX 2 return fader of the UB1832FX-PRO MON The MON switch routes the signals appearing at the AUX RETURN2 jacks to the monitor path, along with the monitor signals from the channels. If you wish to route the effect signal to the monitor mix, you can also switch aux 1 to pre-fader, drive the effect device from the aux 1 output and return the effect signal via AUX RETURN 2 to the monitor signal.
2.3.7 XPQ Surround function (UB1832FX-PRO only)
If you connect a compressor or a noise gate post CD/TAPE OUTPUT, the main mix fader will probably not be able to create a satisfactory fade-out effect.
2.3.9 Lamp socket (UB2442FX-PRO only)
Use this BNC socket to connect a gooseneck lamp (12 V DC, max. 0.5 A).
2.3.10 Level meter and monitoring
Fig. 2.14: Control elements of the surround function The XPQ 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. 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.

While phantom power is switched on, do not connect or disconnect microphones on the mixer (or the stagebox/wallbox). Connect any microphones before switching on phantom power. Additionally, monitor/PA speakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute before adjusting the input gain so that the system has time to stabilize.
Fig. 2.17: PHONES jack PHONES jack You can connect headphones to this 1/4" stereo jack (UB2442FX-PRO: 2 phones jacks). The signal routed to the PHONES connection is the same as that routed to the control room output.
LEVEL METER The high-precision level meters always give you an accurate display of signal level. LEVEL SETTING: When recording to digital recorders, the recorders meter should not go into overload. This is because, unlike analog recordings, it takes only slightly excessive levels to create unpleasant digital distortion. When recording to analog, 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. You should only drive instruments such as a Hi-Hat as far as -10dB. Snaredrums should be driven to approx. 0 dB.
2.3.11 Subgroups and main mix fader
You use the high-precision quality faders to control the output level of the subgroups and the main mix. LEFT/RIGHT switch The switches located above the subgroup faders assign the subgroup signal either to the left or right side of the main bus. Similarly, it can be routed to both sides or none at all. In the latter case, the submix is present only at the corresponding subgroup outputs.
The peak meters of your EURORACK display level almost independent of frequency. A recording level of 0 dB is recommended for all types of signal.
MODE The MODE switch determines whether the channels SOLO switch operates as PFL (Pre Fader Listen) or as solo (Solo In Place). PFL (LEVEL SET) To activate the PFL function, press the MODE switch. The PFL function should, as a rule, be used for level setting (TRIM). The signal is sourced pre-fader and assigned to the mono PFL bus. In PFL mode, only the left side of the peak meter is in operation. A PFLd channel should be driven to the 0 dB mark of the VU meter. SOLO (NORMAL) When the MODE switch is not depressed, the stereo solo bus is active. Solo is actually short for Solo In Place. This is the customary method for listening to an individual signal or to a group of signals. As soon as a solo switch is pressed, all channels not solo selected are muted in th e monitor path (control room and phones). A channels position in the stereo image is maintained. The solo bus carries the output signals of the channel pan controls, the aux sends and the stereo line inputs. On the UB2442FX-PRO all aux returns, and on the UB1832FX-PRO only aux return 2 can be routed to the solo bus. The solo bus is, as a rule, taken post-fader.

Fig. 2.18: Subgroup and main mix faders
The PAN control in the channel strip offers a constant power characteristic. This means that the signal is always at a constant level, irrespective of position in the stereo panorama. If the PAN control
EURORACK UB1622FX-PRO/UB1832FX-PRO/UB2222FX-PRO/UB2442FX-PRO 3. GRAPHIC 9-BAND EQUALIZER (UB1832FX-PRO only)
considerably facilitates use. These effect presets are classical mixing effects. If you move the STEREO AUX RETURN FX control, you mix the channel signal (dry) and the effect signal. You can control the balance between the two signals with the channel fader and the STEREO AUX RETURN FX control. FX OUT Mixing consoles UB2222FX-PRO and UB2442FX-PRO have a separate output for the effects device, which is unbalanced and stereo (tip = left signal; ring = right signal; sleeve = ground/ shielding). Thus, you can record, for example, a vocal track enhanced with reverb in parallel to a dry vocal track; when doing the mix-down later on, you can freely determine the amount of reverb added.
Fig. 3.1: The graphic stereo equalizer of the UB1832FX-PRO The graphic stereo equalizer allows you to tailor the sound to the room acoustics. EQUALIZER Use this switch to activate the graphic equalizer. 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. 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.
+ The UB2442FX-PRO has the effect output on the rear,
UB2222FX-PRO has it located next to the aux sends on the front panel.
FX FOOTSW. Connect a standard foot switch to the foot switch jack and use this to switch the effects processor on and off. A light at the bottom of the display indicates wheater the effects processor has been muted by the foot switch.
In Chapter 6.2 you will find an illustration showing how to connect your foot switch correctly.
LEVEL The LED level meter on the effects module should display a sufficiently high level. Take care to ensure that the clip LED only lights up at peak levels. If it is lit constantly, you are overloading the effects processor and this could cause unpleasant distortion. PROGRAM You can select the effect preset by turning the PROGRAM control. The display flashes with the number of the current preset. To recall the selected preset, press on the button; the flashing stops. You can also recall the selected preset with the foot switch.

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 switch The PHANTOM switch activates the phantom power (necessary to operate condenser microphones) on the XLR sockets of the mono channels. The red +48 V LED illuminates when phantom power is on. As a rule, dynamic microphones can still be used with phantom power, provided that they are wired in a balanced configuration. In case of doubt, contact the microphone manufacturer!
Connect microphones before you switch on the phantom power supply. Please do not connect microphones to the mixer (or the stagebox/ wallbox) while the phantom power supply is switched on. In addition, the monitor/PA loudspeakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute to allow for system stabilization. Caution! Please also note the information given in chapter 6.2.1 Audio connections.
SERIAL NUMBER Please note the important information on the serial number given in chapter 1.3.3.
EURORACK UB1622FX-PRO/UB1832FX-PRO/UB2222FX-PRO/UB2442FX-PRO 6. INSTALLATION

6.1 Rack mounting

The packaging of your mixing console contains two 19" rack mounts for installation on the side panels of the console. Before you can attach the rack mounts to the mixing console, you need to remove the screws holding the left and right side panels. Then, use these screws to fasten the two rack mounts, each specifically to one side. With the rack mounts 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.
