SUPER-X PRO CX2310 User Manual

1. Introduction

If you want to operate a loudspeaker system, which consists of several
loudspeakers covering different frequency bands, then you naturally have
to work with suitably differentiated input signals for each loudspeaker.
To do this you need a frequency crossover which can split the input signal
into several frequency bands. A difference should be noted between passive
crossovers which are wired between amplifier and speaker, and active systems
which are placed before the amplifiers 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 amplifiers,
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.

2. Control Elements

Since the SUPER-X PRO offers 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.
