EUROPOWER EP1500/EP2500
4. INSTALLATION
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.
4.1 Connections
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
®
Speakon
®-
-compatible 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 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.
