Behringer Stereo System CX3400 Manuale Utente

SUPER-X PRO CX3400 User Manual

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

understand the CX3400 and its functions. Please read the manual carefully 

and keep it for future reference.

Multi-way speaker systems can be found almost everywhere today – not only in 

stereo systems, cinemas, discotheques and concert halls. As “customers” become 

more and more demanding, even such “simple” products as TV sets have them 

installed. Why?
With the same sound pressure level, low-frequency sound waves have a much 

greater amplitude than high-frequency signals. When a single loudspeaker is to 

produce both bass and treble frequencies, so-called intermodulation distortion 

will occur.
Don’t worry about unfamiliar terminology! Everybody knows the effect 

that the sound of a fire engine’s siren seems to become lower in frequency, 

once it has passed you. So, the perceived frequency is affected by the motion 

of the sound source or the listener. This phenomenon is called Doppler effect 

(thanks to Mr. Doppler who discovered it) and can also be found in loudspeakers: 

as 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. Quite similar in sound to a vibrato, it is precisely this effect 

that we call intermodulation distortion.
As a consequence, we cannot expect a single loudspeaker to reproduce signals 

with the same quality over the entire audio spectrum. Therefore, 2, 3 or 4-way 

systems have become the standard today. Speakers that need to reproduce only 

a limited range of the audio spectrum can accomplish this task with much 

greater accuracy, i.e. they produce a more regular frequency response and 

dispersion pattern.
To operate a speaker system that consists of several loudspeakers for the various 

frequency ranges, you have to provide a variety of input signals for the single 

speakers. For this purpose, crossover networks split up the input signal into 

several frequency bands. You can use passive crossovers wired between amplifier 

and speaker, or active systems placed before the amplifier in the signal chain. 

Passive crossovers are usually employed in hi-fi speaker boxes.

The BEHRINGER SUPER-X PRO CX3400 is a high-quality active crossover network 

that can be used for 2, 3 or even 4-way sound reinforcement systems.
Whether you need to set up a system for small clubs or large halls, improve an 

on-stage monitoring system or enhance your studio monitors with an additional 

subwoofer: your SUPER-X PRO is the ideal choice for all of these applications.

The philosophy behind BEHRINGER products guarantees a no-compromise circuit 

design and employs the best choice of components. The operational amplifiers 

NJM4580 which are used in the SUPER-X PRO, are exceptional. They boast 

extreme linearity and very low distortion characteristics. To complement this 

design the choice of components includes low-tolerance resistors and capacitors, 

high-quality potentiometers and several other stringently selected elements.
The CX3400 uses SMD technology (Surface Mounted Device). These subminiature 

components adapted from aerospace technology allow for an extreme packing 

density to further improve the overall reliability. Additionally, the unit is 

manufactured in compliance with the ISO9000 certified management system.

Your BEHRINGER SUPER-X PRO CX3400 was carefully packed in the factory 

and the packaging is designed to protect the unit from rough handling. 

Nevertheless, we recommend that you carefully examine the packaging 

and its contents for any signs of physical damage, which may have occurred 

during transit.

Be sure that there is enough space around the unit for cooling and please do 

not place the CX3400 on high-temperature devices such as radiators etc. 

to avoid overheating.

The mains connection of the CX3400 is made by using the enclosed mains 

cable and a standard IEC receptacle. It meets all of the international safety 

certification requirements.
