MIC
Each mono input channel oers 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.
Please mute your monitor system before you switch on phantom ◊
power. Otherwise potentially damaging thumps will be sent to
your speakers. Please also note the instructions in chapter 5.5
“Voltage supply, phantom power and fuse”.
LINE IN
Each mono input also has a balanced line input on a ¼" jack. You can also connect
unbalanced devices using mono jacks 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.
Unlike the X2442USB, the X1622USB, X1832USB and X2222USB have ◊
their insert points located on the rear of the console.
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 dierent value ranges: the rst value range (+10 to +60 dB)
refers to the MIC input and shows the amplication 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 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).
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 eect. The adjacent LED
with light when the eect is engaged.
Equalizer2.1.2
All mono input channels have a 3-band equalizer with semi-parametric mid
bands. All bands provide boost or cut of up to15 dB. In the central position,
the equalizer is o (at).
The circuitry of the British EQs is based on the technology used in the best-known
top-of-the-line consoles and providing a warm sound without any unwanted side
eects. The result are extremely musical equalizers which, unlike simple
equalizers, cause no side eects such as phase shifting or bandwidth limitation,
even with extreme gain settings of ±15 dB.
Equalizer of the input channelsFig. 2.2:
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.
