1.1.2 Initial operation
Be sure that there is enough air space around the unit for cooling
and, to avoid overheating, please do not place the EUROPOWER
near radiators, etc.
Blown fuses must be replaced by fuses of the same
“SPECIFICATIONS” for details.
The mains connection is made using the enclosed power cord
and a standard IEC receptacle. It meets all of the international
safety certification requirements.
Please make sure that all units have proper ground
connection. For your own safety, never remove or
disable the ground conductor from the unit or on
the AC power cord.

Press the FBQ IN switch to activate the FBQ Feedback
Detection System. The frequencies causing feedback are
shown by the brightly lit fader LEDs. Simply lower the level
of the respective frequency range until feedback
disappears and the LED goes out.
2.1 Input channels
The HIGH control in the EQ section governs the highfrequency range of the respective channel.
The LOW control allows you too boost/cut the lowfrequency range.
Turn the FX LEVEL control to add effect to the main mix.
When it is fully counterclockwise, no effect signal is added.
The FX control determines the signal level sent from each
channel to the built-in effects processor.
The 2TR LEVEL control adjusts the volume of the 2 Track

Use this 5-digit LED meter to control the output level of the
main signal. The upper LIM LED illuminates when the internal
amp protection circuit responds to output levels that are
too high.
The LEVEL control adjusts the channel signal level in the
main mix.
The MASTER control is used to adjust the main output
The CLIP LED is very useful to control the input gain. It
should never be constantly illuminated (only with signal
2.3.1 Connectors
The PAD switch reduces the input sensitivity of the channel
by approx. 30 dB, to connect for example line-level signals.
The 2TR IN RCA input allows you to feed in external stereo
signals, e.g. from a CD player, tape deck or other line-level
The balanced LINE IN input (1/4" TRS) can be used for
line-level signal sources, e.g. keyboards.
Each channel has a balanced MIC microphone input with
XLR connectors.
Please remember to use either the microphone or
the line input of a channel at a time, but never both
at the same time!
The REC OUT (RCA) provides line-level signals from the
power mixer to a DAT recorder, for example (two identical
mono signals).
2.2 Effects section
The PMH518M features an AMP INSERT connector for
different applications. You can use just the power stage
of the mixer for connecting a preamp for example. For this
application you can use a 1/4" TS connector where the
signal is sent over the tip of the plug. Additionally you can
use the AMP INSERT as output, so you can use just the
mixer section and connect a separate power amp here.
For this application you have to use a 1/4" TRS connector,
because the signal is send over the ring of the plug.
Be sure that the CLIP LED illuminates for signal peaks only.
If it is illuminated all the time, it is a sign that the effects
processor is overloading and hence producing unpleasant
distortion. The SIG LED below illuminates when the effects
processor receives an input signal.
The EFFECT display shows the currently selected preset.
Turn the PROGRAM control to select an effects preset
(preset number starts flashing). Push the control briefly to
confirm your selection.
Use the POWER switch to put the unit into operation. The
POWER switch should always be in the “Off” position when
you are about to connect the unit to the mains.
Press the FX IN button to activate the effects processor.
2.3 Main section
Your power mixer is equipped with a graphic 7-band
equalizer. Use the EQ to adjust the sound to the room
If the REC OUT signal is connected to a recorder
whose output signal is returned to the 2TR IN,
feedback can occur when you activate the record
function. So, disconnect the 2TR IN from the
recorder, before you start recording!
Please note: The POWER switch does not fully
disconnect the unit from the mains. Unplug the
power cord completely when the unit is not used
for prolonged periods of time.

ensure that the voltage setting matches your local voltage.
Blown fuses should only be replaced by fuses of the same
type and rating. Please also read the information given in
The three PARALLEL SPEAKER OUTPUTs provide the
mono main signal on a Neutrik ® Speakon ®-compatible
connector (pins 1+/1- and 2+/2-) and on two
1/4" TS connectors.
4.1 Mains connection
Blown fuses must be replaced by fuses of the same type and
The mains connection is made using the enclosed power cord
and a standard IEC receptacle. It meets all of the international
safety certification requirements.
The impedance of the loudspeaker connected must
not fall below 4 Ω.
Information on how to properly connect your
speaker with regard to polarity can be found on the
rear of the mixer (PINOUTs).
This is the cooling fan of the unit.
The PMH518M features a built-in digital stereo effects processor.
This effects processor offers a large number of standard effects
such as Hall, Chorus, Flanger, Delay and various combination
effects. Using the FX control, you can feed signals into the
effects processor. The integrated effects module has the
advantage of requiring no wiring. This way, the danger of creating
ground loops or uneven signal levels is eliminated at the outset,
completely simplifying the handling.

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 of the AC power cord.
4.2 Audio connections
The inputs and outputs of the BEHRINGER EUROPOWER are
unbalanced 1/4" TS connectors — except for the balanced mono
line inputs and the balanced XLR inputs. Of course, all inputs and
outputs work with both balanced and unbalanced connectors.
The Tape Ins and Outs are on RCA connectors.
Please ensure that only qualified personnel install
and operate the power mixer. During installation
and operation, the user must have sufficient
electrical contact to earth. Electrostatic charges
might affect the operation of the unit.
Fig. 4.1: 1/4" TS connector
Please be sure to only use commercial Speakon® cables (type
NL4FC) for connecting your loudspeakers to the mixer. Please
check the pin connections of your loudspeakers and cables
depending on the EUROPOWER speaker output you choose.

4.3 Loudspeaker connection
Your EUROPOWER is equipped with high-quality Neutrik ®
Speakon®-compatible loudspeaker connectors, which ensure
safe and trouble-free operation. The Speakon® connector was
especially developed for high-power loudspeakers. Once it is
plugged in, it safely locks into position and cannot be accidentally
disengaged. It prevents the occurrence of electrical shock and
ensures the correct polarity. Each of the connectors carries
only the assigned single signal (see tab. 4.1/fig. 4.5 and the
information on the rear panel of the power mixer).
