EUROLIVE speakers are not designed to be suspended!EUROLIVE SERIES enclosures are designed exclusively for floor-mounted use. Although the enclosures will withstand rough handling over many years, they are not designed to be suspended. [. . . ] OPTIMUM PERFORMANCE The EUROLIVE SERIES was designed for use in a variety of applications. Naturally, the sound of your speaker enclosures largely depends on the acoustic properties of the environment in which it is used. The following points should help you get the most out of your EUROLIVE speaker system. 2. 1 HF driver High frequencies are a crucial part of the audio spectrum, which ensures clear sound and speech intelligibility. Whereas these frequencies are the most easily located, they are also the first to be acoustically blocked. In both modes, the speakers are connected using the Speakon® inputs. + 3. 1 Never change the operating mode while an audio signal is present. FULL-RANGE operation All EUROLIVE models are equipped with a built-in passive crossover network, which ensures a smooth transition between the individual frequency ranges in FULL-RANGE mode. This mode is particularly suitable for applications that require only a small-scale setup, such as speech applications in churches and schools, sound reinforcement in small clubs etc. 3. OPERATING MODES 7 EUROLIVE SERIES 3. 2 BI-AMPING operation 3. 2. 1 Advantages BI-AMPING gives you a number of important advantages: lower distortion, greater flexibility of signal transmission and improved overall system performance. 3. 2. 2 Selecting the crossover frequency For operation with an external crossover network such as our BEHRINGER SUPER-X PRO CX2310, please refer to chapter 6 SPECIFICATIONS for recommended crossover frequencies. We recommend using a slope of at least 12 dBhigher values will improve performance. A slope of 24 dB is ideal. 3. 3 ACTIVE (BI-AMPING)/PASSIVE subwoofer operation EUROLIVE SERIES subwoofers also feature an integrated crossover. Driven in passive mode, the B1500X subwoofer perfectly complements our multi-way system B1020, resulting in a compact, well-balanced and sonically accurate system. If you wish to operate your subwoofer in active mode (switch to BI-AMPING), it can be combined with virtually any of the remaining EUROLIVE multi-way systems. + To ensure optimal performance in combination with the B1020, the polarity of the B1500X subwoofer has been reversed (180°) in the factory. For operation with any other EUROLIVE multi-way enclosure, the loudspeaker polarity must be reversed by qualified service personnel. We designed the B1800X as the perfect subwoofer for the EUROLIVE multi-way enclosures B1220 and B1520. Of course, the B1800X can also be operated either in passive or active mode. The foregoing recommendations are only intended to demonstrate the interaction of various EUROLIVE enclosures. You may, of course, combine enclosures as you like, depending on your personal preferences and applications. 3. 4 Looping through subwoofer signals All EUROLIVE SERIES subwoofers are equipped with two parallel Speakon® connectors. Pins 2-/2+ are directly connected to the loudspeaker. Pins 1-/1+ can be used to loop signals through, while the high-pass signal is present on pins 1-/1+ (output). Please refer to the instructions in chapter 4. + Please note that switching the EUROLIVE subwoofers to BI-AMPING mode moves the input signal of the loudspeakers to pins 2-/2+. In this case, pins 1-/1+ act as a loop-through! 4.
