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.

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.

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
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
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 fine-tuning,
the equalizer should be set to neutral.
LOW CUT
Additionally, the mono channels of the mixing consoles have a high-slope
Additionally, the mono channels of the mixing consoles have a high-slope
LOW CUT filter for eliminating unwanted, low-frequency signal components
(75 Hz, 18 dB/octave).
COMPRESSOR
Each mono channel features a built-in compressor which lowers the dynamic
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 effect. The adjacent LED

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 off (flat).

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 effects. The result are extremely musical equalizers which, unlike simple
equalizers, cause no side effects such as phase shifting or bandwidth limitation,
even with extreme gain settings of ±15 dB.
All Models
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 80 Hz 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. 2.3: 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 - QX1832USB)
and then 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
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
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.

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.

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.
