Behringer EP2500, EUROPOWEREP1500 manual Installation, Connections

The BEHRINGER EUROLIVE SERIES loudspeakers are an outstanding solution for expanding your P.A. system, because each frequency range/application has a speaker type that optimally suits its characteristics.

+Extreme clip limiter settings in bi-amp operating mode can result in balance shifting.

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 EP1500 and EP2500, hot air circulates at the front of the unit to thermally relieve the rack enclosure.

+Fan speed adjusts automatically and assures safe operation. Never block ventilation openings. Should internal temperature reach extreme values, the unit will shut down automatically.

Inputs

Each channel features balanced XLR and 1/4" TRS stereo jack inputs, with input impedances of 20 kΩ (balanced) and 10 kΩ (unbalanced). In general, balanced signals cause less noise than unbalanced signals.

For balanced input signals, use the XLR and 1/4" TRS stereo inputs. For unbalanced input signals, use the unused pin of the XLR connector with grounding. No alteration is necessary on mono jack connectors (see plug type illustrations on page 10).

+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 (GAIN control turned all the way leftward). Otherwise, permanent damage to your speakers may occur.

Outputs

Your EUROPOWER offers several output connection possi- bilities: two Neutrik NL4MD Speakon® connectors and two pairs of touch-safe binding posts. The Speakon® connectors were especially developed for driving high-power speakers. They snap in securely, prevent electric shock and assure correct polarity. The upper Speakon® 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.

+Whenever possible, use thick and short speaker cables to minimize power losses. Never lay out output cables near input cables.
