Behringer SUPER-X PRO CX3400

The CX-3400 V2 Super-X Pro Crossover from Behringer is a stereo 2-way/3-way and mono 4-way crossover that features limiters, time delay, high-frequency horn equalization, and a mono “Low Sum” output, which is ideal for subwoofer applications. It can be used to provide high-precision audio frequency separation in multiple speaker setups for sound reinforcement systems.

The CX3400 V2 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. The front panel is equipped with an easy to read LED matrix, so you can see at a glance which modes have been selected and which controls are active.

Furthermore, the CX3400 V2 includes a switchable pre-EQ for CD horns that ensures a flat-frequency response before equalization is applied. This raises the signal gain by 3 dB at 3.5 kHz, increases a 6 dB/octave up to 22.5 kHz, and provides consistent dispersion over the entire CD horn frequency range.

In stereo mode, the CX3400 V2 can be switched to “mono bass” mode. The LF signals in the left and right channels are summed together and then routed to the channel 1 low-output connector. This connector can be used to drive your active subwoofers, passive subwoofer power amplifiers, or lighting controllers. The low-sum output is presented in mono, since people perceive extremely low-bass frequencies as being omnidirectional.
