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!
What's a Crossover
Chances are if you're reading this, you already know what a crossover is - and you know that you need one. But if you are new to multi-way PA systems, here's a brief overview. Loudspeakers (which we call transducers) convert electrical signals into sound waves. And no matter how well a transducer is designed or made, it simply cannot reproduce the entire audio spectrum all by itself.
Low-frequency sounds tend to push a transducer to the maximum, making it impossible for that same transducer to reproduce the treble content with the sound quality it deserves. (Try singing high falsetto next time you're bench-pressing your limit!) That's why high-quality sound systems use multiple speakers (woofers and tweeters) to spread out the work. While the woofer (usually the larger transducer) does all the heavy lifting, the tweeter can easily handle the high-frequency content. Three and four-way systems distribute the work even more, allowing the individual transducers to reproduce the frequency range for which they were designed. It is the crossover's function to divide these tasks between the various amplifiers and transducers.
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.
