[. . . ] User Manual EUROPOWER EP2000/EP4000 Professional 2, 000-Watt and 4, 000-Watt Stereo Power Amplifier with ATR (Accelerated Transient Response) Technology Thank you Thank you for choosing a BEHRINGER EUROPOWER amplifier. This piece of high-end gear was developed for professional use in live applications, and its many features make it a useful and dependable part of your sound system. The EUROPOWER amps feature an input filter for each channel, enabling you to remove the low-frequency portion of the signal, if desired. Additionally, there is a limiter that protects your loudspeakers. [. . . ] Both channels operate fully independently from one another. There is always a separate input signal as well as a separate output signal. 2. 3. 5 Mono-bridged mode This operating mode enables you to add up the respective voltage of both channels and use it to drive a single loudspeaker. The voltage is therefore doubled, the peak power is quadrupled, and program power is roughly three times as high as that of the individual channels. The input, output, gain, filter and limiter controls belonging to channel 1 are used when running in monobridged mode. The controls belonging to channel 2 are not used. To prevent signal cancellation due to internal phase inversion, the GAIN control belonging to channel 2 must be turned to its left-most position. Use this operating mode to route the power from both channels to a single 8-Ohm or 4-Ohm load. To do so, set up the switches 6 and 7 to "BRIDGE MODE ON". To use the binding posts as your output, you MUST use the two middle posts only. EUROPOWER EP2000/EP4000 User Manual Examples: · 2-channel (stereo) playback · Two independent mono signals, e. g. instrument signal and monitor mix · Bi-amp operation, whereby bass frequencies are run on channel 1, and high frequencies on channel 2 (see chapter 3. 2 "Bi-amping"). Parallel mode is identical to 2-channel mode, except for the inputs of both channels are internally connected in parallel. One input signal routes parallel both channels, while their filters etc. Examples: · A mono signal is fed into both channels, whereby amplification of each channel is controlled separately. · Parallel mode (as described above) with connection of an additional amp via the remaining free input connector. The input signal is present there and may be connected to further equipment. 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.

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: · Driving a single 8-Ohm loudspeaker. [. . . ] Damage/defects caused by the following conditions are not covered by this § 3 Warranty [1].
