User Manual

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. Various operating modes, such as parallel or mono-bridged mode, open up various possibilities for effective

implementation with the rest of your audio equipment for almost any application.

This manual first describes the controls and connection points so that you fully understand the EUROPOWER amplifier and its functions. Then it delves into the various applications where the EUROPOWER amp can be used, and finishes with more details on installing and making the connections to the amplifier.

Have fun with your new amplifier.

Important Safety Instruction

* Caution

This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure - voltage that may be sufficient to constitute a risk of shock.

!!Caution

This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.

!!Caution

◊To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside.

Refer servicing to qualified personnel.

◊To reduce the risk of fire or electric shock, do not expose this appliance to rain and moisture. The apparatus shall not be exposed to dripping or splashing liquids and no objects filled with liquids, such as vases, shall be placed on the apparatus.

◊These service instructions are for use by qualified service personnel only. To reduce the risk of electric shock do not perform any servicing other than that contained in the operation instructions. Repairs have to be performed by qualified service personnel.

◊We would like to bring your attention to the fact that extremely loud sound levels may damage your hearing as well as your loudspeakers. Please lower both GAIN controls leftwards before powering up the unit. Be sure to keep the volume at an appropriate level.

◊Ventilation: The appliance should be situated so that its location or position does not interfere with its proper ven- tilation. For example, the appliance should not be situated on a bed, sofa rug, or similar surface that may block the ventilation openings: or placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.

!!Caution

{1}. Read these instructions. {2}. Keep these instructions. {3}. Heed all warnings.

{4}. Follow all instructions.

{5}. Do not use this apparatus near water. {6}. Clean only with dry cloth.

{7}. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

{8}. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

{9}. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A groundingtype plug has two blades and a third grounding prong.The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

[10].Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

1. Introduction

Honestly, who really likes to read manuals? We know you want to get started right away, but please read this manual carefully and keep it for future reference. It is only after reading these instructions that you will fully understand and be able to use all the features your EUROPOWER amplifier has to offer.

1.1 Before you get started

1.1.1 Shipment

Your EUROPOWER was carefully packed at the factory, and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit.

◊If the unit is damaged, please do NOT return it to BEHRINGER, but notify your dealer and the shipping company immediately. Otherwise, claims for damage or replacement may not be granted.

1.1.2 Initial operation

Please make sure the unit is provided with sufficient ventilation, and never place your EUROPOWER amp on top of other heatemanating equipment or in the vicinity of a heater to avoid the risk of overheating.

The mains connection is made via the enclosed power cord and a standard IEC receptacle. It meets all international safety certification requirements.

◊Please make sure that all units have a proper ground connection. For your own safety, never remove or disable the ground conductor from the unit or the AC power cord.

◊The sound quality may diminish within the range of powerful broadcasting stations and high-frequency sources. Increase the distance between the transmitter and the device and use shielded cables for all connections.

2.3.2 Input filter

The LF (high-pass) filter removes frequencies below 30 and

50 Hz respectively. The reproduction of the signal’s 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.

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.

2.3.1 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 automati- cally 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.
