The Behringer SUPER-X PRO CX3400 is a high-precision stereo 2-way/3-way and mono 4-way crossover designed to split audio signals into separate frequency bands so each loudspeaker driver receives only the frequencies it handles best. It is a proven workhorse for live sound rigs, installed PA systems and studios. The CX3400 uses world-class Linkwitz-Riley filters with 24 dB/octave slopes for a flat summed amplitude response with zero phase difference. Crossover frequencies are continuously adjustable over two ranges (44 Hz to 930 Hz and 440 Hz to 9.3 kHz), and independent limiters on every output protect your drivers from overload. Each band also gets its own gain control, mute switch and phase invert switch for precise system tuning. Additional tools include adjustable time delay on the low output for driver alignment, CD horn correction above 3.5 kHz, and a selectable 25 Hz low-cut filter to remove infrasonic rumble. For sound engineers running multi-amp PA systems for churches, events and venues across Kenya, the CX3400 delivers reliable speaker management at an accessible price.
