Mono Channels; Control Elements And Connectors - Behringer XENYX 1622FX User Manual

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.
• 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 ampli fiers, headphones and 2-track outputs can
also be taken.
• 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/amplifier).
The control surface of BEHRINGER mixing consoles is
opti-mized in such a way that these functions become easy
to fulfil 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 specific
issues, please visit our website at http://www.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.
◊ The block diagram supplied with the mixing console
gives you an overview of the connections between the
inputs and outputs, as well as the associated switches
and controls.

1.3 Before you get started
1.3.1 Shipment
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.
◊
If the unit is damaged, please do NOT return it to us,
but notify your dealer and the shipping company
immediately, otherwise claims for damage or
replacement may not be granted.
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.
1.3.3 Online registration
Please do remember to register your new BEHRINGER
equipment right after your purchase by visiting
www.behringer.com (alternatively www.behringer.de) and
kindly read the terms and conditions of our warranty carefully.
Should your BEHRINGER product malfunction, our goal
is to have it repaired as quickly as possible. To arrange for
warranty service, please contact the retailer from whom the
equipment was purchased. Should your BEHRINGER dealer
not be located in your vicinity, you may directly contact
one of our subsidiaries. Corresponding contact information
is included in the original equipment packaging (Global
Contact Information/European Contact Information). Should
your country not be listed, please contact the distributor
nearest you. A list of distributors can be found in the support
area of our website (www.behringer.com).
Registering your purchase and equipment with us helps us
process your repair claims quicker and more efficiently.
Thank you for your cooperation!

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
XENYX2222FX XENYX2442FX
Fig. 2.1: Connectors and controls of mic/line inputs
MIC
Each mono input channel offers 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 2442FX, the 1622FX, 1832FX and 2222FX
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 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 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 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, low-
frequency signal components (75 Hz, 18 dB/octave).
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
to15 dB. In the central position, the equalizer is off (flat).
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 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.
