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.
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 ampli-
cation 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 possibilities:
two Neutrik Speakon-compatible connectors and two pairs of
touch-safe binding posts. The Speakon connectors were espe-
cially 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 there-
fore 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.
