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 dB—higher 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!

Tab. 4.1: PIN assignments
4.1 FULL-RANGE operation
sUse the switch on the rear panel of the enclosure to select FULL-RANGE. To do this, you must first remove the frame surrounding the switch. (The frame is intended to prevent accidental switching.) Please remember to replace the frame after changing the operating mode.
sAssign the input signal to pins 1-/1+. In this mode, pins 2-/2+ act as a loop-through.
