4.2BI-AMPING Operation

sUse the selector on the rear to set the unit to BI-AMPING mode.

sAssign the subwoofer signal to PINS 1-/1+ and the tweeter signal to PINS 2-/2+.

4.3Subwoofer

sAssign the subwoofer signal to PINS 2-/2+.

sSignal loop through: PINS 1-/1+ are arranged in parallel, so you can loop through a full range and/or high-pass signal to another full range speaker box. Connect the free connector on the subwoofer to PINS 1-/1+ on the full range speaker.

5. WHAT ELSE SHOULD BE CONSIDERED?

5.1Length and cross-section of speaker cables

Speaker cables with too low a cross-section can considerably reduce the performance of your power amps. The longer the cables, the greater the problem. As a consequence, the user tends to “turn up” the power amp, which in turn can lead to speaker damage. You should never use cables longer than 30 m. For most applications this will not be necessary anyway. The cable cross-section should be at least 1.5 to 2.5 mm².

5.2Power amp performance

Choosing the right power amp can be difficult. Try the following rule of thumb: the amp should provide twice as much power as the speakers can handle. A speaker with a continuous power rating of 200 watts can easily be driven by power amps delivering 400 watts of output power.

5.3Fuses

We do not recommend the use of fuses for audio applications. Speaker damage can be caused by high signal peaks or high output power. However, fuses can only protect the speaker against one of these, but never against both. Additionally, fuses can have nonlinear resistances which can lead to distortion and unexpected overdriving of the speakers.

5.3.1 How to protect your system

sMake sure that your audio signal is always set to correct levels. 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. Please consider our proven compressors BEHRINGER AUTOCOM PRO MDX1400, COMPOSER PRO MDX2200 and MULTICOM PRO MDX4400. All models can also be used as limiters. By eliminating overdriving of your audio signals you can effectively suppress disturbing signal peaks.

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