Tune your sound system with the precision it deserves. The Behringer CX3400 Super-X Pro is a high-precision stereo crossover that lets you split your signal into perfectly aligned frequency bands so every driver in your rig does exactly what it was built to do. Whether you run a stereo 2-way, stereo 3-way, or mono 4-way setup, the CX3400 routes the right energy to the right speaker, every time.

Why engineers reach for the CX3400

• State-of-the-art Linkwitz-Riley filters at 24 dB/octave for flat summed response and zero phase difference between bands.
• Built-in limiters on every output protect your loudspeakers from overdrive damage so you can push the system with confidence.
• Adjustable time delays per band keep drivers phase-aligned for tight, focused imaging across the room.
• CD horn correction compensates for constant-directivity horn roll-off so highs stay open and natural.
• Low Sum function sums lows to a dedicated mono output, ready for your subwoofer.
• Independent Gain, Mute, and Phase reverse on every band for fast tuning under pressure.
• 25 Hz low-cut protects your low-end drivers from subsonic energy you can't hear but they can feel.
• Servo-balanced, gold-plated XLR ins and outs, shielded toroidal transformer, and illuminated switches built for the rigors of touring.

From club installs to festival mains, the CX3400 brings the kind of clean band-splitting that used to cost a fortune. Plug it in, dial in your crossover points, and let every speaker do its job.
