1. Introduction

XENYX Mic Preamp
The microphone channels feature high-end XENYX Mic Preamps that compare well with costly outboard preamps in terms of sound quality and dynamics and 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 you to use the greatly extended dynamic range of your
24-bit/192-kHz HD recorder to the full, thereby maintaining optimal audio quality
“British EQ”
The equalizers used for the XENYX Series are based on the legendary circuitry of top-notch consoles made in Britain, which are renowned throughout the world for their incredibly warm and musical sound character. Even with extreme gain settings these equalizers ensure outstanding audio properties.
KLARK TEKNIK Eects Processor
Additionally, your XENYX mixing console has an eects processor designed by KLARK TEKNIK that has 24-bit A/D and D/A converters included, which gives you 32presets producing rst-class reverb, delay and modulation eects plus numerous multi-eects in
excellent audio quality.
CAUTION!
We should like to draw your attention to the fac t that extreme volumes
may damage your hearing and/or your headphones or loudspeakers. Turn the MAIN MIX faders and phones control in the main sec tion 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 fulls three main functions:
• Signal processing:
Preamplication
Microphones convert sound waves into voltage that has to be amplied 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 amplied 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 amplication using an amplier of the highest quality in order to amplify the signal and add as little noise to it as possible. The XENYX Mic Preamp performs this role beautifully, leaving no traces of noise or sound coloration. Interference that could take place at the preamplication level could aect 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.
The XENYX mixing consoles are equipped with a state-of-the-art switched-mode power supply (SMPS). Unlike conventional circuitry an
SMPS provides an optimum supply current regardless of the input voltage. And thanks to its considerably higher eciency a switched-mode power supply uses less energy than conventional power supplies.
FBQ Feedback Detection System
The FBQ Feedback Detection System integrated into the graphic EQ of your QX1832USB is one of this mixer’s 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 XENYX QX1832USB: theVoice Canceller.
The Voice Canceller is a lter circuitry that lters 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.
Frequency response correction
Using the equalizers found in each channel strip, you can simply, quickly and eectively adjust the way a signal sounds.
Eects mixing
In addition to the eec ts 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 eects processors or fed back to the internal eects 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 ers, headphones and 2-track outputs can also be taken.
5 XENYX QX2442USB/QX2222USB/QX1832USB/QX1622USB User Manual
• 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/amplier).
The control surface of BEHRINGER mixing consoles is optimized in such a way that these functions become easy to fulll while the signal path remains simple to follow.

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 specic 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.

1.3 Before you get started

1.3.1 Shipment

2. Control Elements and Connectors

This chapter describes the various control elements of your mixing console. Allcontrols, switches and connectors will be discussed in detail.

2.1 Mono channels

2.1.1 Microphone and line inputs
Your mixing console was carefully packed in the factory to guarantee safe transport. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit.
1.3.2 Initial operation
Be sure that there is enough space around the unit for cooling purposes and to avoid over-heating please do not place your mixing console on high-temperature devices such as radiators or power amps. The console is connected to the mains via the supplied cable. The console meets the required safety standards. Blownfuses must only be replaced by fuses of the same type and rating.
Please note that all units must be properly grounded. For your own
safety, you should never remove any ground connectors from electrical devices or power cables, or render them in operative.
Please ensure that only qualified people install and operate the
mixing console. During installation and operation, the user must have sufficient electrical contact to earth, otherwise electrostatic discharges might affect the operation of the unit.
QX2222USB
Fig. 2.1: Connector s and controls of mic /line inputs
MIC
Each mono input channel oers a balanced microphone input via the XLR connector and also features switchable +48 V phantom power supply for condenser microphones. The XENYX preamps provide undistorted and noise-free gain as is typically known only from costly outboard preamps.
LINE IN
Each mono input also has a balanced line input on a ¼" jack. You can also connect unbalanced devices using mono cables to these inputs.
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.
QX2442USB
Unlike the QX2442USB, the QX1622USB, QX1832USB and QX2222USB
have their insert points located on the rear of the console.
6 XENYX QX2442USB/QX2222USB/QX1832USB/QX1622USB User Manual
WIRELESS INPUT
This connector accepts a USB receiver for use with BEHRINGER ULM wireless microphones. Note that only one source may be used per channel, either the wireless connection, XLR input, or the ¼" input.
GAIN
Use the GAIN 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 dierent value ranges: the rst value range (+10 to +60 dB) refers to the MIC input and shows the amplication 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 GAIN control is turned all the way down, connect your equipment. Set the GAIN 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 GAIN 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 GAIN 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 ne-tuning, theequalizer should be set to neutral.
LOW CUT
Additionally, the mono channels of the mixing consoles have a high-slope LOWCUT lter for eliminating unwanted, low-frequency signal components (75Hz, 18 dB/octave).
The upper (HIGH) and the lower (LOW) bands are shelving lters that increase or decrease all frequencies above or below their cut-o frequency. The cut-o frequencies of the upper and lower bands are 12 kHz and 80Hz respectively. Forthe mid range, the console features a semi-parametric equalizer with a lter 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 eects busses (Aux Sends)
QX1622USB
Fig. 2.3: Aux Sen d control MON and FX in t he channel strip s
QX2442USB
Monitor and eects 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 - QX1832USB) and then routed, for example, to an active monitor speaker or external eects device. Inthe latter case, the eects return can then be brought back into the console via the aux return connectors.
COMPRESSOR
Each mono channel features a built-in compressor which lowers the dynamic range of the signal and increases its perceived loudness. The loud peaks are squashed down and the quiet sections are boosted.
Turn the COMP knob clockwise to add more compression eect. The adjacent LED with light when the eect is engaged.
2.1.2 Equalizer
All mono input channels have a 3-band equalizer with semi-parametric mid bands. All bands provide boost or cut of up to 15 dB. In the central position, theequalizer is o (at).
The circuitry of the British EQ is based on the technology used in the best-known top-of-the-line consoles and providing a warm sound without any unwanted side eects. The result are extremely musical equalizers which, unlike simple equalizers, cause no side eects such as phase shifting or bandwidth limitation, even with extreme gain settings of ±15 dB.
All monitor and eects busses are mono, are tapped into post EQ and oer amplication of up to +15 dB.
Pre-fader/post-fader
When using eects on a channel signal, it is usual to have the aux send post fader so that the balance between eect and dry signal stays constant even when the channel fader is altered. If this were not the case, the eects 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 oers a direct route to the built-in eects processor and is therefore post-fader and post-mute. Please refer to chapter 4 “Digital Eects Processor” for detailed information.
If you are using the built-in effects processor, make sure that
STEREO AUX RETURN 3 has nothing plugged into it (QX2442USB and QX2222USB), 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.
QX1622USB and QX1832USB: 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
QX2442USB
Fig. 2.4: The pano rama and routing co ntrols and the chann el 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 exibility in recording situations. For example, when routing to subgroups 3 and 4, panning hard lef t will route the signal to group output 3 only, and panning hard right will route to group output 4 only.
MUTE
MAIN
The MAIN switch routes the signal to the main mix bus.
The channel fader determines the channel’s volume in the main mix (or submix).

2.2 Stereo channels

2.2.1 Channel inputs
QX2222USB QX2442USB QX2442USB
Fig. 2.5: The various stereo channel inputs
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 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 o the GAIN 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 aecting 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 QX2442USB has 4 subgroups (1-2 and 3-4).
Each stereo channel has two balanced line level inputs on jacks for left and right channels. Channels 9/10 and 11/12 on the QX2442USB feature an additional XLR microphone jack with phantom power. If only the left jack (marked “L”) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals, and, depending on model, have a level switch (+4 dBu or -10dBV) and/or a line GAIN control. Both jack inputs will also accept unbalancedconnectors.
LOW CUT and MIC GAIN
These two control elements operate on the XLR connectors of the QX2442USB, and are used to lter out frequencies below 75 Hz (LOW CUT) and to adjust microphone levels (MIC GAIN).
LINE GAIN
Use this control to adjust the line signal levels on channels 13-16 (QX2442USB only).
LEVEL
For level matching, the stereo inputs on the QX1622USB, QX1832USB and QX2222USB have a LEVEL switch to select between +4dBu and -10dBV. At-10dBV (homerecording level), the input is more sensitive than at +4dBu (studio level).
8 XENYX QX2442USB/QX2222USB/QX1832USB/QX1622USB User Manual
2.2.2 Equalizer stereo channels
The stereo channels contain a stereo EQ section. The cut-o 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 lter type. A stereo EQ is superior to two mono EQs on a stereo signal as two separate EQs will usually result in a discrepanc y 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 rst summed to mono before it reaches the aux bus.
2.2.4 Routing switch, solo and channel fader
Fig. 2.6: Balan ce control and mute s witch
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).

2.3 Interface panel and main section

AUX SEND 1, 2 and 4
The AUX SEND 1 control governs the master send level of the mix created by the individual channel AUX 1 sends.
Likewise, the AUX SEND 2 control is the master control for the aux 2 bus, and AUX SEND 4 controls the AUX 4 bus.
QX2442USB
Fig. 2.7: The AUX SEND cont rols of the main sec tion
AUX SEND 3 (FX)
The FX control determines the signal level for eects processing, i.e. regulates the level to an external (or the internal) eects device.
QX1622USB and QX1832USB: On these consoles, this func tion is performed by the AUX SEND 2 control (FX).
SOLO
You can use the SOLO switch to separately monitor the aux sends via the CONTROL ROOM/PHONES outputs and check these with the level meters.
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).
Where it was useful to trace the signal ow 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)
Turning up the AUX 1 control in a channel routes the signal to the aux send bus 1.
As the QX1832USB is equipped with an additional monitor path, its first
aux control in the channel strips is named MON. The console also has a dedicated master fader (MON SEND) for this aux path.
2.3.2 Aux send jacks
QX2442USB
Fig. 2.8: Aux se nd jacks
QX1832USB
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.
On the QX2222USB, aux send 1 is hard wired as pre-fader and hence
called MON. Model QX1832USB has a dedicated monitor output (MON OUT jack), cf. chapter 2.3.4.
As already mentioned, the aux sends in the channels— if set post-fader— canbe used to connect to external eects devices.
