2.1 Before you begin

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.

+If the unit is damaged, please do not return it to BEHRINGER, 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.

Your BEHRINGER SUPER-X PRO requires 1 height unit of rack space (1 HU). Please allow for an additional 10 cm of rack depth for the rear-panel connectors.

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.

+Before you connect your SUPER-X PRO to the mains, please make sure that your local voltage matches the voltage required by the unit!

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.

+Please make sure that all units have a proper ground connection. For your own safety, never remove or disable the ground conductor of the unit or of the AC power cable.

As a standard, the BEHRINGER SUPER-X PRO is equipped with electronically servo-balanced inputs and outputs. The circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation, even at high operating levels. Externally induced mains hum, etc. will be effectively suppressed. The automatic servo-function recognizes the presence of unbalanced connectors and adjusts the nominal level internally to avoid level differences between the input and output signals (6-dB correction).

Further information can be found in chapter 4 “INSTALLATION”.

2.2 Control elements

Since the SUPER-X PRO boasts a variety of features, we highlighted the active control elements in the following illustrations. On the unit itself, these active elements are equipped with light-emitting diodes, helping you to keep track of your settings even under poor lighting conditions. Additionally, all buttons on the front panel are backlit when activated. Above the control elements there are two labels in the form of strips which refers to mono 4-way (upper) or stereo 2/3-way (lower) configuration. The LEDs below these strips show which controls are active in the respective operating mode.

+On the rear panel, labels above/below the connectors refer to the various crossover modes available. Please make sure that the two MODE switches and corresponding connectors are configured properly; otherwise, you could damage your speakers.

CX3400 specifications

The Behringer CX3400 is a versatile and highly regarded crossover that has become a staple in professional audio setups. This unit is designed to ensure optimal sound quality by efficiently distributing frequencies to appropriate loudspeakers, making it an essential component in sound reinforcement systems, PA setups, and live performances.

One of the standout features of the CX3400 is its three-way or four-way crossover topology, which allows the user to manage sound frequencies with precision. It’s equipped with independent adjustable output controls for each of its outputs, enabling users to tailor the audio experience to fit the specific requirements of any venue or application. The ability to adjust the crossover frequency range from 50 Hz to 6 kHz makes it suitable for various configurations, whether for subwoofers or high-frequency drivers.

Another significant aspect of the CX3400 is its built-in low-pass and high-pass filters. This functionality ensures that low frequencies are directed to subwoofers while high frequencies are sent to tweeters, thus maximizing the efficiency and clarity of each speaker in the system. The filters operate at a steep 24 dB per octave slope, which aids in maintaining the integrity of sound reproduction and minimizes overlap that can lead to distortion.

In terms of technology, the CX3400 features independent audio signal processing capabilities, allowing for more refined control over the audio output. The unit includes a high-quality 24-bit A/D converter and a 24-bit D/A converter, which significantly contribute to the overall audio fidelity and dynamic range. The CX3400 also features balanced XLR inputs and outputs, ensuring that the audio signal is transmitted with minimal interference and noise.

The build quality of the Behringer CX3400 is also noteworthy. It’s designed to withstand the rigors of live performance environments, with a durable chassis that ensures reliability. The user interface is straightforward, with clear, intuitive controls that make it easy to set the desired parameters quickly.

In summary, the Behringer CX3400 crossover is a powerful tool for audio professionals, offering precise frequency distribution, advanced filtering technologies, and solid construction. Its combination of versatility, performance, and user-friendly design makes it an excellent choice for those looking to enhance their sound systems, whether in live settings or recorded applications. The CX3400 continues to be a trusted device for audio engineers, ensuring that every musical element reaches its full potential.
