BEHRINGER SUPER-X PRO CX3400 CROSSOVER The CX3400 is a new, high-precision active frequency crossover enabling 2 or 3-way stereo or even 4-way mono operation. If the drivers in a multi-way system aren`t set up in a vertical line, you often get phase errors and cancellations. CX3400 to the rescue! It enables you to delay the low-frequency bands up to 2 msec., which correlates to moving the speaker backwards up to app. 70 cm. Adjustable crossover frequencies and an additional POLARITY button per output allow perfect runtime and phase problem compensation for various types of speakers and horns. Our special FREQUENCY knobs with 41 detents allow precise setting of both channels` crossover frequencies. Frequency adjustment ranges from 44 to 930 Hz and from 440 Hz to 9.3 kHz (x 10) assure perfect adaptation to any speaker system. Each band features an integrated Interactive Gain Control limiter, which effectively protects your system and speakers against overloading. The threshold for all six limiters is variable between -6 and +18 dB, whereas each limiter operates individually on its particular frequency band. Precise LED displays monitor the status of the limiters and inform you immediately when a limiter becomes active. The lowest frequency band can be merged to a mono signal and separated from the mix, leaving the rest in stereo. Combining the bass cabinets to form a single cluster enables optimal efficiency and notably increased sound pressure level. Additional features include the fact that units can be linked for unlimited frequency bands, 24 dB/octave, state-variable Linkwitz-Riley filters for precise frequency separation, Completely linear, phase-compensated amplitude response when summing signals, MUTE button, phase reverse switch and adjustable output level per band for easy system adaptation, switchable 25 Hz subsonic filter per input (12 dB/octave), switchable equalisation for constant-directivity horns.
