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. 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 off er Mute and Phase Invert switches, making troubleshooting even a large system – virtually effortless! 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.
