EUROLIVE SERIES

4.2BI-AMPING operation

sUse the switch on the rear panel of the enclosure to select BI-AMP. Again, you have to remove the frame first (see chapter 4.1).

sAssign the low-frequency signal to pins 1-/1+ and the high frequency signal to pins 2-/2+ by modifying your connection cable(s).

4.3Subwoofer (PASSIVE)

sAssign the full-range signal to input pins 1-/1+. The high-pass signal is present on output pins 1-/1+. Pins 2-/2+ act as a loop-through.

4.4Subwoofer (ACTIVE/BI-AMPING)

sAssign the subwoofer signal to pins 2-/2+ by modifying your connection cable(s).

sUse pins 1-/1+ to loop the high-pass signal through to pins 1-/1+ of the full-range enclosure.

sIn this operating mode, pins 1-/1+ are always looped through to pins 2-/2+.

5. WHAT ELSE SHOULD BE CONSIDERED?

5.1Length and gauge of speaker cables

Low-gauge speaker cables can considerably reduce the performance of your power amps, and thus of your entire system. The longer the cable, the more crucial the gauge. As a consequence, the user tends to turn up the power amp, which in turn can lead to speaker damage. You should use at least 14-gauge cable—12-gauge is ideal. Try to avoid using cables longer than 30 m (100 ft).

5.2Power amp performance

Choosing the right power amp can be difficult. The following rule of thumb may be helpful: the amp should provide about twice as much power as the speakers can handle. A speaker with a continuous power rating of 200 Watts should be driven by power amps with 400 Watts of output power.

5.3Fuses

We do not recommend the use of fuses for audio applications. Speakers can be damaged by high signal peaks or high output power. Fuses can only protect the speaker against one of these, but never against both. In addition, fuses can have nonlinear resistances, which can lead to distortion and unpredictable overdriving of the speakers.

5.3.1 Protecting your system

sExercise caution while setting levels and avoid overdriving your power amps.

sRespect the physical limits of your P.A. system.

sUse a limiter to limit the output level. Insert the limiter between the mixing console output and your power amp. Our proven compressors COMPOSER PRO MDX2200, AUTOCOM PRO MDX1400 and MULTICOM PRO MDX4400, all of which provide limiter functions, are ideal for this application. Used properly, they can eliminate overdriving of your audio signals and effectively suppress dangerous signal peaks.

+Our crossover network SUPER-X PRO CX3400, which features independent limiters on each individual output, can also be used to protect your system.
