Page 6: Introduction
1.2 SUPER-X PRO: the high-end frequency crossover The BEHRINGER SUPER-X PRO CX3400 is a high-quality active crossover network that can be used for 2, 3 or even 4-way sound reinforcement systems. Whether you need to set up a system for small clubs or large halls, improve an on-stage monitoring system or enhance your studio monitors with an additional subwoofer: your SUPER-X PRO is the ideal choice for all of these applications. -
Page 7: Before You Begin
Your BEHRINGER SUPER-X PRO requires 1 height unit of rack space (1 HU). Please allow for an additional 10 cm of rack depth for the rear-panel connectors. Be sure that there is enough space around the unit for cooling and please do not place the CX3400 on high-temperature devices such as radiators etc. to avoid overheating. - Page 8 THRESHOLD control. This control determines the limiter threshold. LIMITER button. This button activates all limiters. Whenever the signal surpasses the limiter threshold, the LIM-LEDs above the Gain control light up, signaling that the CX3400 cuts back the output level. 2. THE DESIGN CONCEPT...

FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the voltage indicated on the unit, before you attempt to connect and operate the CX3400. Blown fuses may only be replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder in two different positions, in order to switch over from 230 V to 115 V operation, and vice versa. - Page 10 LIMITER button. This button activates all limiters. Whenever the signal surpasses the limiter threshold, the LIM-LEDs above the Gain control light up, signaling that the CX3400 cuts back the output level.

All manuals and user guides at all-guides.com SUPER-X PRO CX3400 Always switch off the entire system before you press this button, as it produces heavy interference noise that could damage your speakers and/or other equipment. LOW SUM button. In stereo mode, the two Low paths can be summed with the LOW SUM button and routed to the Low output of channel 1, which is particularly useful in systems using additional subwoofers. - Page 12 LIMITER button. This button activates all limiters. Whenever the signal surpasses the limiter threshold, the LIM-LEDs above the Gain control light up, signaling that the CX3400 cuts back the output level.

Page 13: Application
For making measurements you need a high-grade microphone with a frequency response that should be as linear as possible over the entire frequency range (e.g. BEHRINGER measuring microphone ECM8000), or at least between 90 Hz and 15 kHz. Place the microphone about 5 m in front of the speaker system to be measured, in a height where it is on axis with the drivers of the two frequency bands you wish to measure. -
Page 14: Finding “Drop-Outs” In The Frequency Response
Thus, you have a wide range of setting options available that even more expensive crossover networks hardly give you. The CX3400 works in two specific frequency ranges: 44 though 930 Hz and 440 Hz through 9.3 kHz. The Linkwitz-Riley filters employed in the SUPER-X PRO feature a slope of 24 dB/octave. High-grade components such as 1%-tolerance metal-film resistors ensure a perfect phase and amplitude response at all crossover frequencies. -
Page 15: Basics Of Electronic Runtime Correction
All manuals and user guides at all-guides.com SUPER-X PRO CX3400 3.5.2 Basics of electronic runtime correction It is important to know how the dimensions of time and space are connected with each other, e.g. by using a tape measure and a pocket calculator. -
Page 16: The Limiters Of The Super-X Pro
When the speaker offset is greater than 68.6 cm you can only move the speaker cabinets. Runtime correction is not the same as the signal delay applied to offset groups of speakers. Here, the entire signal must be delayed by a much greater amount (a suitable delay circuit is included, for example, in the BEHRINGER ULTRA-CURVE DSP8024). -

4" depth for the connectors on the back panel. Be sure that there is enough air space around the unit for cooling and please do not place the CX3400 on high-temperature devices such as power amps, etc. to avoid overheating. -
Page 18: Mains Connection
The fuse holder on the female mains connector has 3 triangular markers, with two of these triangles opposing each other. Your CX3400 is set to the operating voltage printed next to these markers, and can be set to another voltage by turning the fuse holder by 180°.
