7 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.
8 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.
9 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.
10 Fig. 2.4: Active control element s on the rear panel of the SUPER-X PRO 1 Use the enclosed power cord to connect the unit to the mains. 2 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.
11 Fig. 2.6: Active control elements on the front panel of the SUPER-X PRO 1 and 16 INPUT control . This control adjusts the input gain from +12 to -12 dB. 2 LOW CUT button . This button activates the 25-Hz high-pass filter protecting the woofers against low- frequency signals.
12 + 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.
13 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.
14 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.
15 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.
16 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.
17 Modern systems often use bass reflex cabinets for their woofer or sub-woofer 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.
18 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.
19 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.
