When running in mono-bridged mode, the voltage of both channels is added up and fed into a single loudspeaker system. There is one input and one output signal respectively, and only the controls of channel 1 (and not of channel 2) are used.

+However, should the DIP switches 4 and 5 still be in PARALLEL INPUTS position while in mono- bridged mode, the signal on the free input (input channel 2) can be forwarded to an additional amp.

Examples:

sDriving a single 8-Ohm loudspeaker.

sDriving a single 4-Ohm loudspeaker.

+When the amp is overdriven for longer periods of time, the output signal may occasionally be muted for several seconds. In certain situations, excessive overdriving may trigger off the automated fuse. To avoid overdriving the amp, please continually make sure that an appropriate volume level is applied. CAUTION: 2-Ohm loads should never be applied when in mono-bridged mode.

+When connecting a balanced input signal, please make sure to exclusively use balanced cables for passing the signal further on. Otherwise, a single unbalanced cable can turn the entire signal unbalanced.

Safety precautions for mono-bridged

operation

Running your amp in mono-bridged mode can quickly result in excessive overdriving and premature shutting down of the unit itself. In the worst-case scenario, your loudspeakers may be damaged permanently. Therefore, you should always make sure that the speakers you use can indeed handle the power load fed into them.

A voltage of up to 100 V RMS is present between the output connectors of the EP2500. Always implement appropriate safety precautions when connecting your speakers to avoid the risk of electric shock.

3.2 Bi-amping

By using an active crossover, you can divide up the frequency range into several bands. For example, in doing so you can split a mono signal into upper-frequency and lower-frequency ranges. These two signals can then be hooked up to the inputs of your amp, so that channel 1 amplifies the lows and channel 2 amplifies the highs (2-channel operation). The outputs are connected to a 2-way speaker, whereby the output signal 1 drives the woofer and output signal 2 runs the drivers. Of course, you can use two separate speakers instead of a single 2-way speaker.

A stereo signal can also be split up analogous to the example described above. However, to do that you need two 2-way speakers or 4 separate speakers, two EUROPOWER amps and an active 2-way stereo crossover. The BEHRINGER SUPER-X PRO CX2310 is optimally suited for this task and offers additionally a single mono-subwoofer output. By deploying a third EP1500 amp (preferably in mono-bridged mode) and a subwoofer, you have a perfect setup that adds a low-frequency system to the stereo bi-amp application (see fig. 3.4). The amp’s input filters for the high/mid-frequency ranges should in this case be engaged and set at 50 Hz. To remove low, disturbing frequencies from the signal, the input filter for the subwoofer signal should be set at 30 Hz.

They feature XLR and TRS inputs for greater flexibility in connecting to mixing consoles or other audio sources. The outputs include Speakon and binding posts, allowing for compatibility with a wide array of speaker systems.

These amplifiers also incorporate advanced technologies such as a low-noise input stage, which ensures a clean signal path and minimizes distortion. Furthermore, built-in limiters protect the speakers from damage by preventing clipping during high output levels, a crucial feature for maintaining audio fidelity and system integrity.

Another important characteristic of the EUROPOWER series is its reliability. They are designed to handle both low and high frequencies efficiently, ensuring that the sound remains balanced across the entire spectrum. This is particularly beneficial in live sound situations where clarity and punch are essential.

In summary, the Behringer EUROPOWER EP1500 and EP2500 are formidable power amplifiers equipped with high output capabilities, efficient cooling systems, and rugged durability. Their diverse connectivity options and advanced technologies make them suitable for a wide range of audio applications, providing professionals with the reliability and performance needed to achieve outstanding sound reinforcement.
