Behringer : SUPER-X PRO CX3400 Behringer

High-Precision Stereo 2-Way/3-Way/Mono 4-Way Crossover with Limiters, Adjustable Time Delays and CD Horn Correction

The CX3400 stereo 2-way/3-way/ mono 4-way crossover provides the ultimate in high-precision audio frequency separation, thanks to its state-of-the-art circuitry, superior-grade components, ultra low-noise op amps and balanced I/O connectivity. CX3400 features include: Limiters on all crossover outputs for optimal loudspeaker protection; an adjustable Time Delay for proper phase-alignment of the drivers; High-Frequency (HF) horn equalization for constant-directivity compensation; and a mono “Low Sum” Output (stereo modes only), which is ideal for your subwoofer applications.

Sound Quality

When a sound system is properly tuned, it becomes powerful, balanced and efficient. Bass content is punchy and tight, with vocals and instruments that are rich, crisp and well defined. The CX3400 crossover’s accurate signal processing protects critical loudspeaker components and improves overall system efficiency. All Input and Output connections are balanced/unbalanced XLR and feature 25 Hz Low Cut filters for low-frequency driver protection – plus offer Mute and Phase Invert switches, making troubleshooting even a large system – virtually effortless!

Divide and Conquer

The CX3400 provides three modes of operation: 2-way stereo, for Left and Right Lows (woofers) and Highs (tweeters); and 3-way stereo, for Left and Right Lows, Mids and Highs; and 4-way mono, for Lows, Low-Mids, High-Mids and Highs. For your convenience, the CX3400’s front panel features an elegant and easy-to-read LED matrix, so you can see at a glance which operating mode has been selected – and which controls are currently active.

CD Horn Compensation

When a driver radiates into open space via a horn, its efficiency increases. Over the past few years, constant-directivity horns have gained widespread popularity, since they are designed to produce consistent dispersion over their entire frequency range – however, the higher the frequency, the lower the efficiency. To compensate for this, the CX3400 includes a switchable pre-EQ for CD horns that ensures a flat frequency response, even before equalization is applied. This pre-EQ raises the signal gain by 3 dB at 3.5 kHz, which then increases by 6 dB/oct. up to 22.5 kHz.

Low Sum Output

In stereo mode, the CX3400 can be switched to “Mono Bass” mode by pressing the Low Sum button. When this feature is activated, the LF signals in the Left and Right channels are summed together and then routed to the Channel 1 Low Output, where it can be used to drive your active subwoofers, passive subwoofer power amplifiers, or lighting controllers, etc. The Low Sum Output is presented in mono, since people perceive extremely-low bass frequencies as being omnidirectional.
