3. OPERATING MODES
Except for the PA SUBWOOFER all speaker systems from the EUROLIVE SERIES can be operated in two
different modes: FULL RANGE and BI-AMPING. In both modes, the speakers are connected using the high-
quality inputs.
+
Never change the operating mode, while an audio signal is active on the EUROLIVE.
3.1 FULL RANGE operation
Except for the subwoofer all EUROLIVE models are equipped with a built-in passive crossover network, which
ensures a smooth transition between the individual frequency range in FULL RANGE mode. This mode is
particularly suitable for small clubs and speech applications in churches and schools as well as for all applications
that require only a small-scale setup.
3.2 BI-AMPING operation
3.2.1 Advantages
BI-AMPING gives you a number of basic advantages: low distortion, greater flexibility of signal transmission
and an improved overall system performance.
3.2.2 Selecting the crossover frequency
When you use an external crossover network such as our BEHRINGER SUPER-X PRO CX3400, please note
chapter 6 “Specifications”, where you find some information on recommended crossover frequencies. We
recommend a slope of at least 12 dB, with higher values providing for improved performance. A slope of 24 dB
is ideal.
3.3 Looping through subwoofer signals
All subwoofers from the EUROLIVE SERIES are equipped with two parallel high-quality connectors.
PINS 2-/2+ are connected to the speaker. PINS 1-/1+ can be used to loop through signals both in FULL
RANGE and BI-AMPING modes. Please follow the instructions given in chapter 4.
