1. Introduction
If you want to operate a loudspeaker system, which consists of several
loudspeakers covering dierent frequency bands, then you naturally have
to work with suitably dierentiated input signals for each loudspeaker.
To do this you need a frequency crossover which can split the input signal
into several frequency bands. A dierence should be noted between passive
crossovers which are wired between amplier and speaker, and active systems
which are placed before the ampliers in the signal chain. Multi-way speaker
systems can be found almost everywhere today—and not only in stereo
systems, but in cinemas, discotheques and concert halls. As customers have
become more demanding they can even be found now in such “simple”
products as TV sets. Why?
With the same sound pressure, low-frequency sound waves have a much
greater amplitude (oscillation range) than high-frequency waves. When a single
loudspeaker tries to produce bass and treble frequencies at the same time,
a so-called intermodulation distortion will occur. This means that, when the
speaker diaphragm is displaced by low frequencies, the treble frequencies seem
to be raised in loudness, or lowered when the diaphragm reverses its direction.
We cannot therefore expect a single loudspeaker to reproduce signals,
spanning the whole audible frequency spectrum at the same level of quality.
If, using a frequency crossover, a loudspeaker only has to reproduce a limited
part of the frequency spectrum and it will do so at a greatly increased level
of quality— thus producing a more regular frequency response
and dispersion pattern.
Connection to the mains is made by means of a mains cable with
an IEC receptacle which complies with the appropriate safety regulations.
◊ Please note that all units must be grounded properly. For your own
safety, you should never remove any ground connectors from electrical
devices or power cords or render them inoperative.

carefully and keep it for future reference.
1.1 Before you begin
The BEHRINGER SUPER-X PRO CX2310 was carefully packed in the factory,
in order to ensure safe transport. Nevertheless, should the box show signs
of damage please check the equipment itself immediately for any signs
of external damage.
◊ 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. Shipping claims must
be made by the consignee.
Be sure that there is enough space around the unit for cooling and please do not
place the SUPER-X PRO on high-temperature devices such as power ampliers,
etc. to avoid overheating.
◊ Before connecting the SUPER-X PRO to the mains, please carefully
check that your equipment is set to the correct supply voltage!
The fuse holder on the female mains connector has 3 triangular markings.
Two of these triangles are opposite each other. The CX2310 is set to the operating
voltage shown next to these markings. It can be set to another voltage by turning
the fuse holder through 180°.
CAUTION: this does not apply to export models, which were designed
e.g. only for a mains voltage of 115 V!
2. Control Elements
Since the SUPER-X PRO oers a variety of features, we have provided the active
controls with suitable light-emitting diodes. These displays help you to keep
track of what is happening even in dark stage environments. Additionally, all the
switches on the front panel are illuminated and can thus show which functions
are presently active. There are two labels in the form of strips, located above
the controls. The text of the upper label indicates mono 3-way, and the lower
label indicates stereo 2-way mode. The LED’s set below these labels show which
controls are active in the respective mode of operation.
◊ On the rear panel, labels above/below the connectors refer to the
various crossover modes available. Please make sure that the
MODE switch and corresponding connectors are configured
properly; otherwise, you could damage your speakers.
2.1 Stereo 2-way operation with separate
subwoofer signal
First, activate the 2-way mode using the MODE switch on the rear panel
(switch depressed). The STEREO LED on the front panel above the LOW CUT
switch in the second channel lights up.
The LED’s above the active control on the front panel then light up. They show
you which controls are active for the mode of operation, which you have selected.
The functions of these controls can be seen from the second strip label. In stereo
operation the func tions of both channels are identical, so that the numbers
on the overview are shown for only one channel.

3. Applications
You will need some tools to help set up the SUPER-X PRO to its optimal
conguration. To set up the crossover frequency you need to know which
frequency range a loudspeaker stack covers, over which range the sound
energy is linearly transmitted, and where reductions or increases in the
frequency response occur. In addition, every room has dierent size and quality
characteristics. These strongly inuence the sound response, since resonances
and reections in the dierent frequency ranges can also lead to reductions
or increases in the sound picture. You will need suitable equipment in order
to be able to recognize and compensate for these features.
3.1 Too ls
You will need a high-grade microphone for making measurements.
This should have a frequency response that should be as linear as possible
(e.g. the BEHRINGER measurement microphone ECM8000) and at least linear
over the range from 90 Hz and 15 kHz. Place the microphone about 5 m. in front
of the speaker system and between the diaphragms of the two frequency bands
you wish to measure. When using a measuring microphone to set the levels for
the individual frequency bands and the crossover frequencies, you should only
operate one loudspeaker stack. For optimal settings you will usually need
to reposition the microphone between two successive measurements.
When used in combination with a measuring microphone and a generator
producing pink noise via an input into the P.A. mixing console, an analyzer
will show the sound energy distribution over the individual frequency bands
(usually in 1/3 of an octave). The BEHRINGER ULTRA-CURVE PRO DSP8024
equalizer/analyzer is the ideal tool for this application.
3.3 Correcting problems
Check the entire frequency response of the system. Rooms have quite
an impact on the frequency response of speaker systems, due to resonance and
various reections, so you cannot expect to achieve a linear frequenc y response
right from the start. To achieve this, you need an equalizer such as the
ULTRA-CURVE PRO DSP8024 or the ULTRA-GRAPH GEQ3102. Look for drop-outs
around the crossover frequencies! If the frequency response is very irregular,
then it can make sense to grade adjust it using the frequenc y crossover,
before using an equalizer (EQ). The errors in the crossover frequency must then
be as far as possible corrected using the EQ.
If the loudspeaker diaphragms in a multi-way system are not exactly aligned
along a vertical axis, the varying distances between the sound source and
the listener result in phase errors and cancellations (also known as the
“comb lter eect”). Particularly in the higher frequencies it is important,
due to the shorter wavelengths, to position the diaphragms above each other
and not next to each other. The various types of construction used in individual
systems (horns, bass reex cabinets etc.) still give rise to run time dierences,
even where the front sides of all systems are aligned vertically above each other.
In this case a run time correction must be made by electronic means. This can
be done by using a delay function. Run time dierences can be compensated
by delaying the frequency bands over a range of milliseconds. This helps avoid
loss of sound quality, particularly in the high tone ranges.
◊ Runtime correction is not the same as phase correction. If a speaker
system has the same run times then it also has the same phases
(unless the polarity of a cable has been reversed). However the
opposite is not necessarily true.
When listening to the overall sound of your system, you should walk around
in the audience area and try to detect resonance frequencies or cancellations.
The sound should be optimized for the position where most of the audience
will be gathered, without however neglecting other areas. This often means
that the system must be operated in mono. Whenever you use technical aids
such as analyzers, measuring microphones, etc., you should check the desired
results with your own ears.
◊ BEHRINGER accepts no responsibility for any damage or destruction
of loudspeakers arising from improper or incorrect use of the
SUPER-X PRO and in particular from actions which are in contravention
with the clearly stated procedures given in this manual.
3.2 Setting the input and output levels
Both inputs oer a gain or loss of up to 12 dB. Normally, the output level on the
mixing console and the input sensitivity of the ampliers are identical, i.e. 0 dB
at the mixing console corresponds with 0 dB at the ampliers. This means that
there is full control over the ampliers. In this case the SUPER-X PRO should
have no eect on the system level and all input and output level settings should
be set at 0 dB. Where e.g. a home recording or disco console is being used with
an operating level of -10 dBV but the ampliers need +4 dBu for complete
control, then an additional gain of 12 dB must be provided between them.
In this case the INPUT control of the SUPER-X PRO should be set to the maximum.
The output levels of the single bands can be raised/lowered by as much as 6 dB.
To achieve a linear frequency response in the system, all output levels should
be adjusted with the help of an analyzer. To check the crossover frequencies and
levels, mute all outputs except for one, and play back pink noise over the system
at an appropriate volume level. When you now switch on the adjacent band,
the level measured around the crossover frequency should go up by 3 dB.
Repeat this process for all crossover frequencies.
3.4 Setting the crossover frequencies
The frequency range from which the crossover frequencies can be selected,
can be one of two ranges—from 44 to 930 Hz and from 440 Hz to 9.3 kHz.
To set the crossover frequencies, please rst read the manufacturers’
specications for the individual loudspeaker components. To use the capacity
of your system at its best you should set up the crossover frequencies in
accordance with the frequency diagrams on the individual loudspeaker boxes.
Further, the crossovers should not lie on peaks or drop-outs. Look for a range
with the attest possible curve. If folded bass horns are being used, then the
length of the horn path must also be taken into account, since the run time
displacements arising from diering long paths can also have a negative eect
on the frequency development (see chapter 3.3).
◊ Never operate loudspeakers or horn drivers below the limiting
frequency specified by the manufacturer!
3.5 SUBWOOFER output
To achieve a very loud and deep bass playback the SUPER-X PRO has an additional
mono subwoofer output for 2-way and 3-way operation. In this sense the
CX2310 is a stereo 2-way + mono 1-way or mono 4-way frequency crossover.
The subwoofer signal is mono, since people cannot sense the location of lower
frequencies. Another reason is that combining all bass signals into a single signal
produces an excellent eect. This is because two bass speaker boxes combined
together produce 3 dB more sound pressure than if they were separated from
each other by a small distance. The increased pressure is due to the speakers
producing a single wave front. With four loudspeaker boxes the increase is 6 dB.
The reason here is the spherical shape of the expanding low-frequency sound
waves. Bass boxes which are separate from each other can mutually disrupt each
other where their sound waves meet (what happens here can be easily imagined
if you throw two stones into water—rst separately and then stuck together).

4. Audio Connections
As a standard, the BEHRINGER SUPER-X PRO CX2310 is equipped with
electronically servo-balanced inputs and outputs. The circuit design features
automatic hum suppression for balanced signals and so ensures trouble-free
operation, even at the highest operating levels. Externally induced mains hum,
etc. can therefore be eectively suppressed. The automatic servo-function
recognizes the presence of unbalanced connectors and adjusts the nominal level
internally to avoid level dierences between the input and output signals
(6-dB correction).
◊ Please ensure that only qualified persons install and operate the
SUPER-X PRO. During installation and operation the user must have
sufficient electrical contact to earth. Electrostatic charges might affect
the operation of the unit.
