EUROPOWER EP4000/EP2000 Controls
Step 2: Controls
Since control elements of both the EP2000 and the
(EN)
EP4000 are identical, we have used the EP2000
as the model represented in the illustrations to
assure simplicity.
(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 unit's power cord from the
power outlet.
(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.
(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
powered up.
(7) These are the balanced XLR inputs
(channels 1 and 2).
(8) These are the stereo ¼" TRS inputs
(channels 1 and 2). They can also be used with
unbalanced plugs.
(9) These are the MODE switches, used to alter the
operating modes as well as to set the limiters
and high-pass filters.
(10) The unit's fan is located here. Fan speed
adjusts automatically to assure
trouble-free operation.
◊
To prevent faulty operation, please assure
that the unit is kept at a distance from
other appliances emanating heat.
These are the speaker outputs (channels 1
(11)
and 2). When running the unit in mono-
bridged mode, please use the channel 1
output exclusively.
(12) These are the output terminals (channels 1
and 2). When running in mono, please make
sure to use both middle connectors to connect
your loudspeaker.
BREAKER (automated fuse). After eliminating
(13)
the cause of faulty operation, simply depress
the BREAKER and power up the unit again.
The BREAKER acts in place of common
discardable fuses.

Caution
◊ Before engaging the BREAKER switch,
you should power down the unit
(POWER switch set to OFF)!
(14) Power is supplied via an IEC connector.
The matching cable is provided with the unit.
(15) SERIAL NUMBER of your EUROPOWER.
(16) Here you can fi nd a detailed overview of the
individual MODE SWITCHES functions ((9)).
When running in mono-bridged mode, the voltage
of both channels is added up and fed into a single
loudspeaker system. There is one input and one
output signal respectively, and only the controls of
channel 1 (and not of channel 2) are used.
◊ However, should the DIP switches 4 and 5
still be in PARALLEL INPUTS position while
in mono-bridged mode, the signal on
the free input (input channel 2) can be
forwarded to an additional amp.
Examples:
• Driving a single 8-Ohm loudspeaker.
• Driving a single 4-Ohm loudspeaker.

◊ When the amp is overdriven for longer
periods of time, the output signal
may occasionally be muted for several
seconds. In certain situations, excessive
overdriving may trigger off the automated
fuse. To avoid overdriving the amp,
please continually make sure that an
appropriate volume level is applied.

◊ 2-Ohm loads should never be applied when
in mono-bridged mode.
◊ 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.
Safety precautions for mono-bridged operation
EUROPOWER EP2000 (Stereo Mode)
◊ 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 of the

safety precautions when connecting your
speakers to avoid the risk of electric shock.
