Since control elements of both the EP2000 and the EP4000 are identical, we have used the EP2000 as the model represented in the illustrations to assure simplicity.
[3] The CLIP LED lights up when the signal is distorted. Should distortion occur, reduce the input level, so that the CLIP LED stops lighting up. [4] The SIGNAL LED lights up as long as a signal is present at the input. [5] The Gain control (channels 1 and 2) is used for setting up the input gain. [6] The POWER LED lights up as soon as the unit is poweredup.
[1] The main switch is used to power up the amp.
Merely switching the unit off does not mean that it is fully
disconnected from the mains. When not using the unit for prolonged periods of time, please unplug the units power cord from the poweroutlet.
[2] Ventilation openings are located at the front of the unit, so that hot air is prevented from being trapped inside the unit, thus causing faulty operation or even damage.

[11] These are the speaker outputs (channels 1 and 2). When running the unit in mono-bridged mode (see chapter 2.3.5), please use the channel 1 output exclusively. For further information on the connectors please refer to chapter4.1. [12] These are the output terminals (channels 1 and 2). When running in mono, please make sure to use both middle connectors to connect yourloudspeaker. [13] BREAKER (automated fuse). After eliminating the cause of faulty operation, simply depress the BREAKER and power up the unit again. The BREAKER acts in place of common discardable fuses.

2.3.1 Clip limiter When the input signal connected to your amp is too high, you end up with a distorted output signal. To prevent this, both channels of your EUROPOWER feature a clip limiter that can be engaged or disengaged selectively. The limiters automatically recognize distortion and lower amplification until distortion is reduced to a tolerable level. To preserve the dynamic characteristics of the signal when low distortion levels are occurring, the clip limiters function with moderate suppression. Use switches 1 (ch. 1) and 10 (ch. 2) to activate the clip limiters. When using broadband loudspeaker systems, the clip limiter reduces high frequency distortions which occur when an amplifier is overloaded. The drivers are thus protected from being damaged. 2.3.2 Input filter The LF (high-pass) filter removes frequencies below 30 and 50Hz respectively. The reproduction of the signals bass portion is thus optimized, since ultra-low, distracting frequencies are eliminated, and more power is available for the reproduction of the wanted segment of the signal. Engaging and disengaging the filters is done by using the switches 3 (ch. 1) and 8 (ch. 2). Switches 2 (ch. 1) and 9 (ch. 2) determine the cut-off frequency. As long as the filter is disengaged, frequencies below 5 Hz are cut to prevent damage. You should set up the filters so they best suit the frequency response of your speakers, since some speakers (e.g. bass reflex speakers) are particularly sensitive to over-excursion below the listed frequency range.

Caution

Before engaging the BREAKER switch, you should power down the unit
(POWER switch set to OFF)!

The 50 Hz filter should be engaged when using broadband speakers because the filter provides a moderate amplification in the 100-Hz range, resulting in a fuller sound. The 30 Hz filter is ideally suited for subwoofer operation as well as for broadband cabinets. The Off setting should be used only for special applications (e.g. studio applications), in which recognizing and subsequently removing infra-sound is important. 2.3.3 2-channel mode (stereo) Both channels of your amp function independently from one another in this operating mode, and each has its own input signal. Two independent speakers are connected at the outputs. To activate this operating mode, please set the MODE SWITCHES 4 and 5 to STEREO.
When running the unit in two-channel mode, the switches for

3. Applications

Running EUROPOWER amplifiers in conjunction with 8-Ohm speakers
with a power rating of at least 2 x 400 Watts (EP2000) and 2 x 750 Watts (EP4000) is recommended to assure optimal operation.
3.1 Differences between 2-channel, paralleland mono-bridged operating modes
2-channel mode is the most common operating mode of amplifiers. Bothchannels operate fully independently from one another. There is always aseparate input signal as well as a separate output signal. 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
mono-bridged mode must be disengaged (dip switches 6and 7 in leftposition). 2.3.4 Parallel mode Running in parallel mode enables you to feed a signal via one of the inputs into both outputs. Each channel drives its own loudspeaker with independent amplification, filter and limit characteristics. To link the inputs, set the MODESWITCHES 4and 5 to PARALLEL INPUTS.
Mono-bridged mode switches must be disengaged when running in
frequencies on channel 2 (see chapter 3.2 Bi-amping).
parallelmode. With inputs set to parallel, you can use the remaining input connectors to feed the signal into additional amplifiers. This means that the channel 2 inputs function as outputs. The parallel mode is well-suited for applications in which driving two speakers with the same signal but with separate amplification, filter and limiter settings is desired. 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 mono-bridged 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 BRIDGEMODEON. To use the binding posts as your output, you MUST use the two middle postsonly.

The mono-bridged mode puts added demands on amplifier and

speakers. Excessive distortion may occasionally completely mute the amps outputs as well as cause permanent damage to the speakers. Please assure that your speakers (minimal impedance 4 Ohms) as well as the cables used can handle the extra power generated in this mode.

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. are independently controlled. Examples:
A mono signal is fed into both channels, whereby amplification of each

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.

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
EUROLIVE B1520 Full range loudspeaker EUROPOWER EP2000 (Stereo Mode)
of the EP4000. 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 2amplifies 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-wayspeaker. 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 EP2000 amp (preferablyin 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. 3.7). The amps 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.

4. Installation

Your EUROPOWER can be installed into a 19" rack and requires two rack units. Please use four attaching screws and washers for installation. Reinforce the back end, especially for on-the-road use. Please assure that enough cool air reaches the rack, especially when other rack equipment emanates a lot of heat. In the case of the EUROPOWER EP2000 and EP4000, hot air circulates at the front of the unit to thermally relieve the rack enclosure.
Fan speed adjusts automatically and assures safe operation.
4.1.1 Using the binding posts To connect the loudspeakers to the amplifiers binding posts, please do thefollowing: 1) Switch off the amp and disconnect it from the mains (unplug mains connector). 2) Remove the protective plastic covers shielding the binding posts by loosening the two screws on the right-hand side of the connections and lift the plastic cover upwards. 3) Attach the terminal of your loudspeaker cable to the corresponding bindingpost. 4) Place the protective plastic covers into its original upright position on each binding post and replace the two screws.
Never operate the device without the protective plastic covers in place!
Neverblock ventilation openings. Should internal temperature reach extreme values, the unit will shut down automatically.

4.1 Connections

Inputs Each channel features balanced XLR and " TRS stereo jack inputs, withinput impedances of 20 k (balanced) and 10 k (unbalanced). In general, balancedsignals cause less noise than unbalanced signals. For balanced input signals, use the XLR and " TRS stereo inputs. For unbalanced input signals, use the unused pin of the XLR connector with grounding. Noalteration is necessary on mono jack connectors.
Should you register distractive signals such as noise or hissing,
we recommend separating the amp input from the signal source. This way, you can quickly determine if the noise originates in the equipment connected to the amp. Always make sure to completely lower amplification of both channels before powering up the amp (GAINcontrol turned all the way leftward). Otherwise,permanentdamage to your speakers may occur. Outputs Your EUROPOWER offers several output connection possibilities: two professional speaker connectors and two pairs of touch-safe binding posts. The professional speaker connectors were especially developed for driving high-power speakers. They snap in securely, prevent electric shock and assure correct polarity. Theupper connector drives either one or both channels, and is therefore well-suited for mono-bridged operation (1+/2+). The lower connector carries the signals from channel 2 only.
