Introduction

FBQ Feedback Detection System

One of the most outstanding features of this console is the FBQ Feedback Detection System, which is part of the graphic equalizer. This ingenious circuit makes it possible to detect and subsequently eliminate feedback frequencies very quickly. FBQ increases the brightness of the EQ fader LEDs for the frequency bands where feedback is occurring. What used to be a tedious search for feedback frequencies is now mere child's play.

IMP "Invisible" Mic Preamp

The microphone channels are equipped with BEHRINGER's brand-new high-end IMP Invisible Mic Preamps, which offer you:

• 130 dB of dynamic range and hence an unbelievable amount of headroom,
• a bandwidth from below 10 Hz to above 200 kHz for the crystalclear reproduction of even the slightest details,
• extremely noise and distortion-free circuitry for absolutely natural sound and neutral signal reproduction,
• perfect adaptation to any microphone on the market (upto 60 dB gain and +48 V phantom power), and
• the possibility of pushing the dynamic range of your 24-bit/192kHz HD recorder to the max and thus achieving ultimate audio quality.

What is more, the EURODESK comes with two effects processors using 24-bit A/D and D/A converters and the effects algorithms of our renowned 19" multi-effects device VIRTUALIZER PRO DSP2024P.
Each processor offers 99 presets with first-class room simulations, delay and modulation effects as well as compressor, tube distortion and numerous other effects available—all with excellent audio quality!

The mixer is equipped with a state-of-the-art integrated switch-mode power supply. Unlike conventional designs, this supply automatically adapts to supply voltages between 100 and 240 V. With its considerably higher efficiency, it is also more economical in terms of power consumption than standard power supply units.

The manual

This manual is designed to give you an overview of all control elements and at the same time inform you in detail about how to use them. To provide you with a clear structure, we have grouped the control elements according to their function. They can easily be found on the enclosed numbered illustrations. If you need more detailed information on specific topics, please visit our web site at www.behringer.com. The product-related information pages and the ULTRANET-based glossary explain the relevant audio engineering terminology in full detail.

Control elements and connections

This chapter describes the various control elements of your mixing console. All controls and connections are explained in full detail.

Mono input channels

Microphone and line inputs

Connectors and controls of the mic/line inputs

1. Each mono input channel is equipped with a balanced microphone input on an XLR connector, which provides +48 V phantom power for condenser microphones at the touch of a button (see rear panel).

• Be sure to switch off your audio system before you activate the phantom power supply to prevent audible switch-on thumps from reaching your monitor speakers. Please also note the information given in chapter "Rear panel".

2. Each mono input also has a balanced line input on 1/4" TRS connectors. Of course, these inputs can also be used with unbalanced plugs (1/4" TS connector).
3. The INSERT I/O connector is used to process a signal with dynamic processors or equalizers. This insert point isprefader, pre-EQ and pre-aux send.
   Unlike reverb and other effects, which are usually added to the dry signal, dynamic processors process the entire signal. So, aux send buses are not the best solution here. Instead, dynamic processors and equalizers are inserted into the signal path. Once processed, the signal then re-enters the mixing console at the same point where it left. Signal interruption only occurs if a plug is inserted into the corresponding jack (1/4" stereo plug: tip = signal output, ring = input). All mono input channels are equipped with insert points. They can also be used as pre-EQ direct outputs, without signal flow interruption. For this you need a cable with a 1/4" TS connector on the recorder/effects processor end, and a bridged stereo 1/4" TRS connector on the console end (tip and ring interconnected).
4. The TRIM control adjusts the input gain. Be sure to set this control fully counter-clockwise before you connect or disconnect a signal source to or from one of the inputs.
   TRIM has a dual scale: the first scale has a gain from +10 to +60dB for the MIC input.
   The second scale has a gain from +10 to -40dBu for the line input. For devices with a nomal line output level of-10 dBV or +4 dBu the setting is as follows: with TRIM fully counterclockwise connect the external device and adjust the output level recommended by the manufacturer. If available, the output level display of the external device should read 0 dB with signal peaks. For +4 dBu increase TRIM, for -10 dBV increase it further. The fine-tuning can be done with a music signal and the LEVEL SETLED, which will illuminate when the optimum operating level has been set.
5. Mono channels are equipped with a high-slope LOW CUT filter eliminating unwanted low-frequency signals, such as floor rumble (18 dB/oct., -3 dB at 80 Hz).

Equalizer

All mono input channels are equipped with a 3-band equalizer. The maximum boost/cut of the individual bands is 15 dB, in mid position the EQ is set to neutral.

Equalizer section of input channels

6. The HI control in the EQ section controls the high frequency range of the respective channel. It is a shelving-type filter which can boost or cut all frequencies above a fixed frequency (12 kHz).
7. The MID control allows you to raise or lower the mid-range level. It is a semi-parametric peak filter, which boosts or cuts the frequency range around a variable mid-range frequency. Use the FREQ control to select the mid-range frequency from 100 Hz to 8 kHz. Then use the MID control to boost or cut the selected frequency range.
8. The LOW control boosts or cuts the low-frequency range. Like the HI filter it is a shelving-type filter, which raises or lowers the level of all frequencies below a specific frequency (80 Hz).

Aux/FX send buses

Aux sends enable you to take the signals from one or multiple channels and collect them on one bus. This signal is then present at one of the aux send jacks, from where it can be routed to an active monitor speaker or external effects device, for example. The FX returns are subsequently used as a return bus for the processed signal.

AUX/FX send controls in the channel strips

9. On each channel, the AUX 1 and AUX 2 controls allow you to determine the level of the aux signals sent from the channel. The main aux send signal comprising the aux send signals from all channels can then be adjusted with the corresponding master AUX SEND controls , and is present at the AUX SEND outputs . Both aux sends are mono, post-EQ, with a gain of up to +15 dB.
10. Press the PRE switch to set all aux sends to pre-fader. In this case, the volume of the aux signals is no longer dependent on the fader position, so you can create completely independent monitor mixes.

• For most applications when controlling an external effects device from one of the aux buses, the aux sends must be set post-fader, so that the effect volume in a channel depends on the position of the channel fader. Otherwise, the effect signal would still be audible, even if the channel was turned down completely. For this type of application it is advisable to leave the PRE switch out (= not pressed).

11. FX 1 and FX 2 controls provide a direct route to the built-in effects processor. Additionally, they can be used to control an external effects unit, via the FX SEND 1 and 2 outputs (similar to the AUX SEND 1 and 2 jacks). To ensure that the internal effects processor and the FX SEND outputs actually get a signal, the corresponding FX control must not be set fully counter-clockwise (-oo), and the master FX SEND (see ) must be turned up. The FX buses are hard wired post-fader.

• Please also read chapter "Effects section" and3 "DIGITAL EFFECTS PROCESSOR".

Mono channel fader and further control elements

Channel fader, pan control, mute button, etc.

12. The PAN control determines the position of the channel signal in the stereo mix as well as the subgroup to which the channel signal is routed.
13. Use the MUTE switch to mute the channel signal, so it is no longer part of the main mix. At the same time, all aux buses set to post-fader are muted for the respective channel, while the pre-fader monitor buses remain operative. The MUTE LED is illuminated when the channel is muted.
14. The CLIP LED illuminates when the channel overloads. In this case, please reduce the input gain using the TRIM control. This LED also illuminates when you activate the solo function with the SOLO switch below.
15. The SOLO switch routes the channel signal to the solo bus (Solo In Place) or the PFL bus (Pre Fader Listen). Thus, you can monitor a channel signal without affecting the main output signal. The signal to be monitored is taken either pre (PFL, mono) or post-panorama control (Solo, stereo) and post-channel fader (depending on the position of the SOLO/ PFL switch ).
16. The SUB switch routes the signal to the respective subgroups. Your EURODESK features 4 subgroups (1-2 and 3-4). With the PAN control on the input channel (see ) you can determine to which of the two groups the signal is routed (hard left: sub 1 or 3, hard right: sub 2 or 4).
17. The MAIN switch routes the signal to the main mix.
18. The channel fader governs the level of the channel signal as part of the main mix (or submix).

Stereo channels

Channel inputs

Stereo channel inputs

19. Each stereo channel is equipped with two balanced line-level inputs on 1/4" TRS connectors for the left and right channels. The channels can also process mono signal, as long as you use the "LEFT" jack only.
20. All stereo channel strips have a TRIM control for gain adjustment. Its scale ranges from +20 to -20 dB and allows you to adapt the input level to the line inputs.

Stereo channel equalizer

Stereo channel equalizer

The stereo channels are equipped with a stereo equalizer. The filter types and cutoff frequencies for HIGH and LOW filters are the same as on the mono channels. Instead of one semi-paramtric midrange band, the stereo channels have two separate midrange bands ( HIGH MID and LOW MID) with fixed mid-frequencies (3 kHz and 400 Hz). Stereo EQs are preferable for processing the frequency response of stereo signals. With two mono equalizers you might encounter problems with different settings between the left and right channels.

Stereo channel aux/FX send buses

Basically, the aux and FX buses on the stereo channels are the same as on the mono channels. Since aux buses are always mono, the signal from a stereo channel is first mixed to mono before it is routed to the aux bus.

Stereo channel fader and other control elements

Channel fader, balance control, mute switch, etc.

22. The BAL(ANCE) control has the same function as the PAN control on the mono channels. It determines the relative volume of the left and right input signals before they are routed to the stereo main mix bus (or to two subgroups).

All other control elements of the stereo channels work in the same ways as their counterparts on the mono channels (faders, MUTE switches, etc.).

• Please note: When you route a stereo channel to the subgroups using the SUB switches, please be sure to set the BAL control to its mid position, so that the signal is sent to two subgroups and remains stereo.

Stereo channels 21 - 24 (SL2442FX-PRO) or 29 - 32 (SL3242FX-PRO)

Auxiliary stereo channels

Your EURODESK has two stereo channels with an aux send section ( AUX 1 and AUX 2) and one LEVEL control . For these channels, the aux buses are hard-wired to pre-fader and are therefore particularly useful for monitoring. They have no routing switches and are always sent to the main mix. Like the normal stereo channels they have two line-level inputs on1/4" TRS connectors for the left and right channels, and a SOLO switch.

Similar to the CD/TAPE inputs (see ) the auxiliary stereo channels can be connected to CD players, tape decks, etc., for example, to feed in playback material.

Subgroups 1 - 4

Subgroups 1 - 4

The EURODESK has 4 subgroups enabling you to create mono or stereo mixes from multiple input signals. Subgroups are controlled from one (mono) or two (stereo) subgroup faders. Additionally, it is possible to connect the subgroup outputs as tape sends to a multi-track recorder.

25. The subgroup faders determine the volume of the subgroup signal at the subgroup output . Depending on the position of the routing switch you can thus control the subgroup volume in the main mix.
26. The SOLO switch routes the subgroup signal to the solo bus (Solo In Place) or PFL bus (Pre Fader Listen), so that you can monitor the subgroup signal without affecting the main or sub output signals. The signal to be monitored is taken either pre (PFL, mono) or post-subgroup fader(Solo, stereo), depending on the position of theSOLO/PFL switch ). The SOLO LED illuminates when the SOLO switch is pressed.
27. Use the routing switches for the subgroups to send the subgroup signal to the main mix. You can route it to the left stereo side (=LEFT pressed), to the right stereo side (=RIGHT pressed) or to both (=LEFT and RIGHT pressed).
    For example, when you have created a stereo submix using subgroups 1 and 2, be sure to route group 1 to the left and group 2 to the right side to maintain proper stereo positioning. If it is a mono submix with just one subgroup, route it to the left and right sides of the main mix to make the signal audible on both sides.
    
    Subgroup outputs 1 - 4
28. These four SUBGROUP OUT (puts) carry the signals of the individual subgroups. For multi-tracking connect the outputs to the inputs of a multi-track recorder (see chapter "Studio set-up").

Mono out section for subwoofer applications

Using this auxiliary mono output you can route the main mix signal to a separate power amp. The tunable low-pass filter allows you to limit the signal content to the low-frequency range to get a perfect subwoofer signal. This signal is mono because very low frequencies disperse quickly, so there would be no benefit to position this signal in the stereo mix.

Mono out fader and low-pass filter

29. The MONO fader controls the volume of the signal present at the MONO OUT (see ).
30. The FREQ control adjusts the cut-off frequency of the lowpass filter (30 to 200 Hz). Frequencies above cut-off are filtered out when activated.
31. Use the LOW PASS FILTER switch to activate the filter function (LED illuminates).
    
    Fig. 2.12: Mono out connector
32. The MONO OUT connector provides the line-level mono signal for connection to the inputs of a power amp or active speaker. You can also use this output as a monitor bus, e.g. to connect a headphone amplifier. In this case, the signal should of course not be limited by the low-pass filter.

Main out section

Main out fader

33. Use this high-precision MAIN fader to control the output level of the main mix.
    
    XLR main out connectors
34. The MAIN OUT(puts) are balanced XLR connectors with a nominal operating level of +4 dBu and provide the main mix signal.
    
    Main out connectors and main insert
35. The MAIN OUT 1/4" TRS connectors outputs also provide the main mix signal.
36. Like the channel inserts, the MAIN INSERT connectors can be used to connect a dynamics processor or equalizer for further processing of the mix signal. The MAIN INSERT refers to the Main Outs (XLR and 1/4" TRS connectors), the MONO OUT (see ) and, if the MAIN switch in the PHONES/CONTROL ROOM section is pressed, also to the PHONES/CTRL ROOM output (see ).
    
    Level meter
37. The red "+48 V" LED illuminates when phantom power is on. Phantom power is required for the operation of condenser microphones, and can be switched on with the corresponding switch on the rear of the console.
38. The POWER LED is illuminated when the console is switched on.
39. The high-precision level meter accurately indicates the output signal level. For example, when you press the SOLO switch on one of the input channels, its signal level will be displayed here, either pre-fader (PFL) or post-fader (SOLO), depending on the position of the SOLO/PFL switch (see ). In PFL mode only the left display is active, because the PFL signals are mono.
40. The SOLO/PFL switch determines whether the monitored signal is pre (PFL) or post-fader (SOLO) after pressing the SOLO/PFL switch (the LED illuminates). The level meter indicates the corresponding signal (see ). When you adjust a signal with the TRIM control, it is advisable to select PFL mode, so that the level shown is independent of the channel fader position.

Talkback

The talkback function of the EURODESK allows you to communicate with the musicians in the recording room or on the stage. The talkback signal is present at the AUX SEND outputs, which are particularly useful for monitor/headphone mixes.

Talkback section

41. The LEVEL control determines the volume of the talkback signal at the AUX 1/2 outputs.
42. Use the TALK TO AUX 1/2 switch to activate the built-in talkback microphone. Its signal is sent to the AUX SEND jacks 1 and 2. Keep the switch pressed while you're speaking.
43. This is the built-in talkback microphone.

Phones & control room

Phones/control room section

44. The PHONES/CTRL R control adjusts the volume of the headphones connected to the PHONES/CTRL ROOM OUT jack (see ). If you have an active monitor speaker or power amp connected here, you can also control the monitor volume.
45. These switches select the signal sent to the PHONES/CTRL ROOM jack. Available sources are: MAIN, CD/TAPE, AUX 1/2 and subgroups 1 - 2 and 3 - 4.
    
    Phones/control room output
46. Connect your headphones or monitor speaker to the PHONES/CTRL ROOM OUT 1/4" TRS connector.

• 
  High volume levels may damage your hearing and/or your headphones/loudspeakers. To avoid switch-on/off thumps from the console and any downstream devices, always make sure that the power amp(s) or active speaker(s) are the last components that are switched on and the first to be switched off. Always make sure that the appropriate volume is set.

CD/tape

CD/tape

47. TO MAIN controls the volume of, for example, a CD player connected to the CD/tape input connectors (see ).
48. When the STANDBY switch is pressed, all input channels are muted. Only the CD/tape signal will be routed to the main mix. In this way, you can prevent the microphones from pickung up unwanted sounds or noise that would interfere with CD playback during a break. The main mix and channel faders can remain in their normal positions while playing back music from CD (using the CD/TAPE INPUTs ), so you don't lose your mix.
    
    CD/tape connectors
49. The CD/TAPE INPUT RCA connectors are for the connection of CD players, tape decks or other line-level sources. The signal volume is adjusted with the TO MAIN control.
50. The CD/TAPE OUTPUT RCA connectors provide the stereo main mix signal to a tape deck or DAT recorder to record your mix. The signal is taken pre-fader, so that it will not be influenced by the fader positions.

Master aux send 1 and 2

Master aux sends

51. These are the master AUX SEND controls 1 and 2 for adjusting the volume level sent to the corresponding aux send connectors (see ). This way, you can control the mix of all AUX 1 or AUX 2 signals of the input channels. The AUX SEND section also has a SOLO switch.
    
    Master aux send outputs
52. Use the AUX SEND outputs 1 and 2 to take the masterAUX SEND signals and route them to an external effects device or your monitor speakers. Subsequently, you can return the effect signal, e.g. via the STEREO FX RETURN inputs (see ) or specific input channels.

Graphic 9-band stereo equalizer

The graphic stereo equalizer

53. Your EURODESK is equipped with a graphic 9-band stereo equalizer processing either the main or the AUX 1 signal. Use the EQ to adapt the sound to the room acoustics.
54. Use the EQ IN switch to switch the equalizer on. In this case, the fader LEDs illuminate.
55. With the MAIN/AUX 1 switch you can determine the signal to be processed, either main or AUX 1.
56. Press the FBQ IN switch to activate the FBQ Feedback Detection System. The frequencies causing feedback are indicated by the brightly lit fader LEDs, while all other LEDs are darker. Simply lower the level of the brightly lit faders until feedback disappears. +

• When the switch is in the "AUX 1" position (see ) the EQ fader LEDs show both the MAIN and the AUX 1 signal simultaneously. However, if feedback occurs in one of the signals, those signals without feedback will be faded out to enable clear identification of where feedback is occurring. If the MAIN signal happens to be the one carrying feedback, put the switch to "MAIN" and then use the 9-band EQ to remove the feedback.

Effects section

The digital effects processor

57. Here you will find a list of all multi-effects presets (see also chapter "DIGITAL EFFECTS PROCESSOR").
58. The FX LED level meters show the effects processor's input signal. Be sure that the clip LED only illuminates with signal peaks. If it is lit all the time, the effects processor is overloading and hence producing unpleasant distortion.
59. The EffeCt displays show the currently selected presets.
60. This is the master FX 1 (or 2) SEND control for adjusting the volume of all FX send signals at the corresponding FX send jacks (see ) and at the inputs of the built-in effects processor. Use it to control the master signal of all FX 1/FX 2 signals from the input channels. When neither of the FX SEND controls is turned up, the effects processor will not receive a signal.
61. Turn the FX 1 (or FX 2) control to select an effects preset.
    Then, push it briefly to confirm your selection and activate the new effect.
62. The FX 1 (or 2) TO AUX 1 controls allow you to add the effect signal from the built-in effects processor (FX1 or FX2) to the AUX 1 monitor signal. Naturally, the effects processor must be provided with an input signal (i.e. the FX controls in the channel strips plus the FX SEND controls and the channel faders must be turned up).
63. This is the FX 1 (or 2) TO AUX 2 control adding the effect signal from the effects processor to the AUX 2 monitor signal. See for further details.
64. The FX 1 (or 2) TO MAIN control routes the effect signal either to the main mix or the subgroups 1 and 2 (or 3 and 4), depending on the position of the selector switch (see ). When it is hard left, no effect signal will be audible. Here, too, the FX controls in the channel strips plus the FX SEND controls and the channel faders must be turned up.
65. These selector switches route the effect signal to the main mix or to the subgroups 1-2 or 3-4. If the MAIN/SUB switch is not pressed, the effect signal is sent to the main mix and the SUB 1/2 / SUB 3/4 switch below is inoperative. If the upper switch is pressed (SUB), however, the lower switch determines whether the effect signal is routed to subgroups 1 and 2 (SUB 1/2) or 3 and 4 (SUB 3/4).
    
    FX send and return connectors
66. The FX SEND 1 and 2 connectors also provide the master FX send signals, for example, to connect them to the inputs of an external effects device. However, these are "dry" signals only with no "effect signals" from the built-in effects processor!
67. The Stereo FX RETURN inputs 1 and 2 return the effect signals from external effects processors and add them to the main mix.
    
    Footswitch connectors
68. The FOOTSW(ITCH) connector allows you to connect a standard dual footswitch to separately enable/disableFX 1 or FX 2. The tip of the 1/4" plug controls FX 1, the ring controls FX 2.

Rear panel

The rear panel of the EURODESK

69. Use the POWER switch to put the mixer into operation. This switch should always be in the "Off" position when you connect your unit to the mains.

• Please note: The POWER switch does not fully disconnect the unit from the mains. To disconnect the unit from the mains, pull out the main cord plug or appliance coupler. When installing the product, ensure the plug or appliance coupler is readily operable. Unplug the power cord when the unit is not used for prolonged periods of time.

70. With the PHANTOM switch you can activate the phantom power supply for the XLR connectors of the mono channels for condenser microphones. The +48 V-LED illuminates when phantom power is on. In most cases, dynamic microphones can still be used as long as they are connected in a balanced configuration. If in doubt, please contact the manufacturer of your microphone!
71. The mains connection is a standard IEC receptacle. An appropriate power cord is supplied with the unit.
72. FUSE HOLDER. Before connecting the unit to the mains, ensure that the voltage setting matches your local voltage. Blown fuses should only be replaced by fuses of the same type and rating. Please also read the information given in chapter "SPECIFICATIONS".
73. SERIAL NUMBER.

Digital effects processor

List of all effects presets

99 FIRST-CLASS PRESETS

Here is the list of all multi-effects presets. The built-in effects processor offers you various standard effects such as reverb, chorus, flanger, delay and a variety of combination effects from our renowned studio effects processor VIRTUALIZER PRO DSP2024P.
Use theFX control on the channels and the FX SEND control to supply the effects processor with signals. A built-in digital stereo effects processor has the benefit of no external wiring, thus reducing the risk of ground loops or level differences. Handling is therefore much easier.

PARALLEL FX

The effects presets 1 to 70 provide classic "add-to-mix" effects. So, when you turn up the FX 1 (or 2) TO MAIN control, you create a mix of the (dry) channel signal and the effect signal. The balance between the two signals can be set with the FX send and FX 1/2 TO MAIN controls.

This also applies to adding effect signals to the AUX 1 (or 2) monitor mix, with the exception that the mix here is adjusted with the AUX 1 (or 2) control in the channel strip and the FX TO AUX 1 (or potentiometer. Of course, the effects processor must receive a signal from the channel using the FX 1 (or 2) control. Make sure that the PRE switch in the corresponding channel strip(s) is pressed. Otherwise, the AUX buses will be set post-fader making the volume of the AUX monitor signal dependent on the position of the channel fader(s).

INSERT FX (channel is muted)

Effects presets #71 and higher process the entire signal, unlike the "add-to-mix" effects. When you use an insert preset, be sure to separate the respective channel from all buses (SUB button and MAIN button not pressed) and only route the effect signal to the main mix (FX 1/2 control, FX SEND 1/2 control and FX TO MAIN 1/2 control).

• The channel fader of the corresponding channel remains active and governs (in combination with the FX controls) the signal level sent to the built-in effects processors.

Wiring examples

Studio set-up

The following wiring example shows a studio set-up for 4-track-recording: the drums are mixed down to two subgroups and then routed via the subgroup outputs to two tracks of the multi-track recorder. The remaining two subgroups are used to record the guitar, keyboard (stereo channel) and two vocal signals on the remaining two tracks. The four return paths from the recorder are connected to four separate mono input channels on the EURODESK. The built-in compressor is used only for the bass, which is why this input channel is separate from all buses (SUB and MAIN switch not pressed). The bass signal is directly routed from the built-in effects processor to the respective subgroups (FX TO MAIN control). The MAIN/SUB switch in the FX1 section is pressed, but NOT the SUB 1/2 SUB 3/4 button.

Wiring the console for studio operation

• Please make sure that none of the subgroup routing switches (1-2 and 3-4) is pressed in the channels connected to the recorder returns. Otherwise, a feedback loop will be created as soon as you start recording. Only press the MAIN switch on these input channels, so that the tape return signals are routed to the main outs and Phones/CTRL room outputs of the console.

Live set-up

Wiring the console for live operation

This example shows a classic live set-up. As in the studio example, four drum microphones, bass, keyboard (stereo channel), guitar and two vocal microphones are connected. The four drum channels (kick drum, snare, overhead L, overhead R) are mixed down to two subgroups and then routed to the main mix. This way, it is possible to conveniently control the volume of the entire drums in the main mix with the two subgroup faders. The built-in compressor insert effect is used for the bass. The corresponding input channel is separate from all buses and the bass signal is routed directly from the internal effects processor to the main mix bus. The MAIN/SUB switch must not be pressed in this case and the position of the SUB 1/2 SUB 3/4 switch is irrelevant.

Audio connectors

The inputs and outputs of the BEHRINGER EURODESK are designed as unbalanced 1/4" TS connectors—except for the balanced line inputs of the mono and stereo channels and the main out connectors. Of course, all inputs and outputs work with both balanced and unbalanced connectors. The tape ins and outs are stereo RCA connectors.

• Please ensure that only qualified personnel install and operate the EURODESK. During installation and operation, the user must have sufficient electrical contact to earth. Electrostatic charges might affect the operation of the unit.
