SUPER-X PRO CX3400 1. INTRODUCTION Thank you very much for expressing your confidence in BEHRINGER products by purchasing the SUPER-X PRO CX3400. + This manual first describes the terminology used, so that you can fully understand the CX3400 and its functions. Please read the manual carefully and keep it for future reference. 1.1 Multi-way speaker systems Multi-way speaker systems can be found almost everywhere today not only in stereo systems, cinemas, discotheques and concert halls.
SUPER-X PRO CX3400 2.1 Before you begin Your BEHRINGER SUPER-X PRO CX3400 was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit.
SUPER-X PRO CX3400 Fig. 2.2: Proper selection of the two MODE buttons for stereo 2-way operation Subsequently, the LEDs above the active controls on the front panel light up, signaling which controls are active in the operating mode you just selected. The functions of these controls can be seen from the second strip label. In stereo mode, both channels perform the same functions.

SUPER-X PRO CX3400 + 9 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. 12 LOW (LF SUM) OUTPUT connector. Output for the Low band signal. 13 XOVER FREQ. button.
SUPER-X PRO CX3400 6 LOW OUTPUT control. Controls the output level of the Low band from +6 to -6 dB. 7 LOW PHASE INVERT button. This button reverses the polarity of the Low output. 8 LOW MUTE button. Mutes the Low band. 9 LOW-MID OUTPUT control. Controls the output level of the Low-Mid band from +6 to -6 dB. 10 LOW-MID PHASE INVERT button. This button reverses the polarity of the Low-Mid output. 11 LOW-MID MUTE button. Mutes the Low-Mid band. 15 CD HORN button.
SUPER-X PRO CX3400 3. APPLICATION 3.1 Tools The following tools are indispensable for a perfect system alignment. You should by all means try to obtain the speaker specifications from the manufacturer, in order to operate the systems in their proper frequency and level ranges. Use the manufacturers documentation to adjust the operating mode and crossover frequencies. + BEHRINGER does not assume any responsibility for speaker damage caused by improper handling of the SUPER-X PRO. 3.1.
SUPER-X PRO CX3400 3.3.1 Finding drop-outs in the frequency response Check the entire frequency response of the system. Rooms have quite an impact on the frequency response of speaker systems, due to resonance and various reflections. So, you cannot expect to achieve a linear frequency response right from the start. Use an equalizer such as our ULTRA-CURVE PRO DSP8024 or ULTRA-GRAPH GEQ3102.
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. Example: a delay of 2 ms corresponds to a distance of 68.6 cm; when you measure an offset of 30 cm you can calculate the necessary delay as follows: 2 ms x 30 / 68.6 = 0.87 ms.
SUPER-X PRO CX3400 Modern systems often use bass reflex cabinets for their woofer or subwoofer systems. Consequently, when stacking the cabinets, the drivers are usually aligned along the vertical axis of the speaker front, or can at least be aligned using the available control range of the SUPER-X PRO. Here, runtime correction follows the same principle as in midrange/high-midrange/tweeter systems. Problems will be encountered only with unconventional setups (e.g.
SUPER-X PRO CX3400 The limiter threshold can be set from -6 dB to OFF and acts on all six limiters at the same time. Still, each limiter band works independently, with the LIM-LEDs lighting up as soon as the associated limiter is activated. + Please note that the limiters in the SUPER-X PRO are no hard ratio limiters, i.e. signal peaks can surpass the adjusted threshold by as much as 6 dB. Please make sure that your system provides enough headroom. 3.6.
SUPER-X PRO CX3400 4.2 Mains connection Before you connect your SUPER-X PRO to the mains, please make sure that your local voltage matches the voltage required by the unit! 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°.
