1. Introduction

If you want to operate a loudspeaker system, which consists of several

loudspeakers covering dierent frequency bands, then you naturally have

to work with suitably dierentiated input signals for each loudspeaker.

To do this you need a frequency crossover which can split the input signal

into several frequency bands. A dierence should be noted between passive

crossovers which are wired between amplier and speaker, and active systems

which are placed before the ampliers 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.

◊ This manual first describes the terminology used, so that you can fully

understand the SUPER-X PRO and its functions. Please read the manual

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 ampliers,

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!

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.

1.2 Online registration

2. Control Elements

Since the SUPER-X PRO oers 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 functions 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

conguration. 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 dierent size and quality

characteristics. These strongly inuence the sound response, since resonances

and reections in the dierent 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 Tools

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.

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 oer a gain or loss of up to 12 dB. Normally, the output level on the

mixing console and the input sensitivity of the ampliers are identical, i.e. 0 dB

at the mixing console corresponds with 0 dB at the ampliers. This means that

there is full control over the ampliers. In this case the SUPER-X PRO should

have no eect 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 ampliers 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.

3.3 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 reections, so you cannot expect to achieve a linear frequency 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 frequency 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 eect”). 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 reex cabinets etc.) still give rise to run time dierences,

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 dierences 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.

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’

specications 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 diering long paths can also have a negative eect

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 eect. 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 eectively suppressed. The automatic servo-function

recognizes the presence of unbalanced connectors and adjusts the nominal level

internally to avoid level dierences 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.
