EUROPOWER PMX660M/PMX880S
1. INTRODUCTION
Congratulations! With the PMX660M/PMX880S you have
acquired a state-of-the-art power mixer that sets new standards.
Right from the very start it has been our goal to design a
revolutionary unit that can be used for a wide variety of
applications. And indeed, this overwhelming power mixer gives
you plenty of functionality and a broad range of connection and
expansion options.
Your power mixer features our revolutionary COOLAUDIO
amplifier technology that reduces weight and size of your device
and provides extreme high output power.
Further advantages are the integrated V ice Canceller that
removes vocal tracks from a playback, the FBQ function for
feedback detection and the Speaker Processing function for
adjusting the frequency response of any loudspeakerand
everything with 24-bit/46 kHz resolution.
The mixing consoles of the PMX series feature a state of the
art, integrated switch-mode power supply (SMPS). One of the
great advantages is that (compared to conventional circuits) a
switch-mode power supply adapts to mains voltages between
100 and 240 volts automatically. Furthermore, due to its much
greater efficiency, it consumes much less energy than a
conventional power supply unit.
BEHRINGER is a company with its roots in professional
recording studio technology. For many years we have been
successful in developing products for studio and live use. These
include microphones and 19" units of all types (compressors,
enhancers, noise gates, tube processors, headphone amplifiers,
digital effects, DI boxes, etc.), monitor and P.A. speakers as
well as professional live and recording mixers. Our entire
technical know-how has gone into your PMX power mixer.

Please take the time to fill in and return the warranty card within
14 days after the date of purchase, so as to benefit from our
extended warranty. Or register online at www.behringer.com.
1.2 The manual
This manual is designed to give you both an overview of all
control elements and to provide detail about how to use them. To
provide you with a clear structure, we have grouped the control
elements according to their function. They can easily be found
on the enclosed numbered illustrations. If you need more detailed
information on specific topics, please visit our web site
www.behringer.com. The product-related information pages and
the ULTRANET-based glossary explain the relevant audio
engineering terminology in full detail.
2. CONTROL ELEMENTS
A detailed description of all functions of your power mixer can
be found in the following chapters. Please also refer to the
enclosed sheet with the numbered illustrations to get an overview
of the control layout.
2.1 Mono and stereo channels
The HI control in the EQ section governs the high-frequency
range of the respective channel.
Use the MID control to boost or cut the mid-range
frequencies.
The LOW control allows you too boost/cut the low-frequency
range.
With the MON control you can adjust the volume of each
channel in the monitor mix.
The FX control determines the signal level sent from each
channel to the built-in effects processor this signal is also
present at the FX OUT jack (see ). The PMX880S has
two FX controls (FX 1 and FX 2), so that you can use two
effects simulteneously. Accordingly, it also provides two
effect Aux paths (see ).
+Please n te that the effects pr cess r signal will
be inaudible when the FX RETURN c ntr l ( ) is
set fully c unter-cl ckwise.
For the mono input channels, the PMX880S has a
PAN(ORAMA) control which determines the position of the
channel signal in the stereo main mix. The PMX660M has
no PAN on the input channels, because it is a dual-mono
power mixer.
The BAL(ANCE) control for the stereo channels of the
PMX880S corresonds to the PAN control for the mono
channels. It determines the relative volume of the left and
right input signals before they are routed to the stereo main
output. The PMX660M has no stereo channels and hence
no BAL control, because it is a dual-mono power mixer.

5
EUROPOWER PMX660M/PMX880S
2. CONTROL ELEMENTS
The LEVEL control adjusts the channel signal level in the
main mix.
2.1.1 Input sect on
The CLIP LED is very useful to control the input gain. It
should never be constantly illuminated (only with signal
peaks).
The PAD switch reduces the input sensitivity of the channel
by approx. 30 dB, to connect for example line-level signals.
The balanced HI-Z input (1/4" TRS) can be used for line-
level signal sources, e.g. keyboards, electric guitars and
basses.
Each channel has a balanced LOW-Z microphone input
with XLR connectors, which also supply the +48 V phantom
power for condenser microphones (see ).
Unbalanced stereo line inputs with 1/4" connectors for
stereo channels 7 to 10 of the PMX880S. They can be
used for connecting keyboards with stereo outputs or
stereo drum machines.
+Please remember t use either the micr ph ne r
the line input f a channel at a time, but never b th
at the same time!
+When y u c nnect m n line-level signals t
channels 7 t 10 f the PMX880S, always use the left
input. The m n signal will then be repr duced by
b th stere sides.
2.2 Effects section
List of all multi-effects presets.
LED level meter of the effects processor. Since the
PMX880S allows you to select two effects simultaneously,
it also has two level meters (DUAL FX). 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 EFFECT display (PMX880S: two displays) shows the
currently selected preset.
Turn the PROGRAM control (PMX880S: one control each
for FX 1 and FX 2) to select an effects preset (preset
number starts flashing). Push the control briefly to confirm
your selection.
Press the FX IN button (PMX880S: FX 1 IN and FX 2 IN) to
activate the effects processor.
2.3 Main and monitor section
Your power mixer is equipped with two graphic 7-band
equalizers. The upper one processes the monitor signal,
the lower one the main signal. Use the EQs to adjust the
sound to the room acoustics.
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. Your power mixer offers
this function both for the main and the monitor mix.
Turn the FX RET control to add the effect signal to the main
mix (lower) or monitor mix (upper). The PMX880S allows
you to use two effects at the same time, it also has two FX
controls each for the main and monitor mixes: when the FX
RET 1 and FX RET 2 controls are fully counter-clockwise,
no effect signal is added.
The 2TR IN control adjusts the volume of the
2 Track In signal (see ).
The MONITOR MASTER control adjusts the monitor output
volume.
Use this 5-digit LED meter to control the output level of the
monitor signal. The upper LIM LED illuminates when the
internal amp protection circuit responds to output levels
that are too high.
The MAIN MASTER control is used to adjust the main output
volume.
Use this 5-digit LED meter to control the output level of the
main signal. The PMX880S has two rows of LED meters
(L/R), because the signal is stereo. The upper LIM LED
illuminates when the internal amp protection circuit
responds to output levels that are too high.
+48V phantom power is provided for condenser
microphones. The phantom power supply is activated for
all channels with the PHANTOM switch and the PHANTOM
LED above the switch illuminates.
Use the POWER AMP switch to determine the operating
mode of your power mixer.
The PMX880S has three different operating modes: In MAIN
L/MAIN R mode it functions as a stereo amplifier, i.e. the left
and right main stereo signals are sent to OUTPUT A (L)
and OUTPUT B (R). In MON/MONO mode it functions as a
dual mono amplifier. I. e. OUTPUT A sends the monitor signal,
and OUTPUT B the main signal (mono). In BRIDGE AMP
MODE the output power of outputs A and B are added
and provided at OUTPUT B.
The PMX660M also has three operating modes, since it can
be operated in two modes with the switch in its upper position
(MAIN/MAIN (BRIDGE) mode), depending on the pin
connections of the speaker cables. In MAIN/MAIN (BRIDGE)
mode power of both outputs is added and provided at
OUTPUT B (SPEAKON® cable, pins 1+/2+). With the normal
pin connections (SPEAKON® cable, pins 1+/1-) a main signal
is provided in this mode at OUTPUT A and B (not bridged). In
MON/MAIN mode, the mixer can also be used as a dual
mono amplifier, i.e. OUTPUT A provides the monitor signal,
while the main signal is present at OUTPUT B.
Please refer to and as well as chapter 4.4
Loudspeaker connectors.
+In BRIDGE m de, always c nnect nly ne l udspeaker
with an impedance f at least 8 W t OUTPUT B (pins
1+/2+)! Please n te that OUTPUT A must NEVER be
used in BRIDGE m de (with pin c nnecti ns 1+/2+)!
+In all ther perating m des, the minimum
impedance f the speaker c nnected must n t fall
bel w 4 Ω.
Use the SPEAKER PROCESSING switch to activate a filter
that adapts the mixer to the specifications of your
loudspeakers. If the speakers have a limited frequency
response in the bass range, it allows you to adapt it optimally
to the frequency response of the speakers.

EUROPOWER PMX660M/PMX880S
2. CONTROL ELEMENTS
If STANDB is pressed, all input channels are muted.
During breaks you can thus prevent the microphones from
picking up noise or interference, which would then be
reproduced by the P.A. system. The advantage is that all
faders can be left untouched while you play a CD via the
CD/TAPE inputs (see ). There is also no need to move
down the faders of muted channels and lose your mix.
2.3.1 Connectors
The FOOTSWITCH connector is for a standard
footswitch. You can activate an effect bypass that mutes
the effects processor. Please use a dual footswitch for
the PMX880S, so that you can enable/disable FX1 and FX2
independently of each other. In this case, the tip of the 1/4"
plug controls FX1, and the ring FX2.
The FX OUT connector is used to route the FX SEND signal
from the input channels, for example, to the input of an
external effects processor. The PMX880S has two
FX controls per input signal (see ) and also two
FX OUT connectors (FX OUT 1 and FX OUT 2).
+Please n te: When y u c nnect a m n plug t ne
f the FX OUT jacks, the signal path fr m the
respective FX send t the built-in effects pr cess r
is interrupted. F r each FX send y u can either use
the built-in effect r the c rresp nding FX OUT jack
(f r an external effect), but never b th at the same
time. When y u use a stere plug (tip and ring
interc nnected) y u can use the built-in effects
pr cess r and the FX OUT jacks in parallel.
Use the AUX IN 1/4" inputs to route an external stereo
signal to the main mix. This can be the signal generated by
an external effects processor. Use the left input for mono
signals, which are then reproduced on both stereo sides.
The PMX660S has only one mono AUX IN connector.
The AUX IN control adjusts the volume of the external
signal in the main mix.
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
source.
The VOICE CANCELLER filters vocal-specific frequencies
from the 2TR IN signal. This function can be used
for karaoke, i.e. you can remove the vocals from
a song and then sing along with the music yourself.
The REC OUT (RCA) provides line-level signals from the
power mixer to a DAT recorder, for example. On the
PMX880S the REC OUT signal is stereo and on the
PMX660M two identical mono signals are provided.
+If the REC OUT signal is c nnected t a rec rder
wh se utput signal is returned t the 2TR IN,
feedback can ccur when y u activate the rec rd
functi n. S , disc nnect the 2TR IN fr m the
rec rder, bef re y u start rec rding!
The MAIN 1/4" connectors allow you to send the main
signal to an external amplifier, when you only wish to use
the mixer and effects section. The signal is taken pre-
power stage of the mixer. It is also possible to use only the
left jack of the output. The PMX660M has only one mono
output connector.
Connect your monitor power amps or active monitor
speakers to the mono MONITOR output to monitor the
signal mix created with the MON controls or to route it to
the musicians on stage.
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.
+Please n te: The POWER switch d es n t fully
disc nnect the unit fr m the mains. Unplug the
p wer c rd c mpletely when the unit is n t used
f r pr l nged peri ds f time.
2.4 Rear panel
The mains connection is on a standard IEC receptacle. An
appropriate power cord is supplied with the unit.
FUSE HOLDER. Before connecting the unit to the mains,
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
chapter 6 SPECIFICATIONS.
These are the two cooling fans of the unit.
Loudspeaker OUTPUT A.
PMX880S: Depending on the operating mode selected (see
) either the left main signal or the monitor signal is
provided at OUTPUT A. NEVER use this output in bridged
mono mode.
PMX660M: In MON/MAIN mode, the monitor signal is provided
at OUTPUT A (see ). NEVER use this output in bridged
mono mode, except when you use a cable with the normal
pin connections (SPEAKON® cable: pins 1+/1-). In this case
you can take the mono main signal from this output in
MAIN/MAIN (BRIDGE) mode (not bridged). Please also refer
to chapter 4.4 Loudspeaker connection.
+The impedance f the l udspeaker c nnected must

PMX880S: Depending on the operating mode selected (see
) either the right main signal, the mono main signal or
the bridged mono signal is provided at OUTPUT B.
PMX660M: Either the main or the bridged main mono signal
is provided at OUTPUT B (see ). When you use a cable
with the normal pin connections (SPEAKON® cable: pins
1+/1-), it is possible in MAIN/MAIN (BRIDGE) mode to take
the mono main signal from this output (not bridged). Please

3. D G TAL EFFECTS PROCESSOR
3. DIGITAL EFFECTS PROCESSOR
A special feature of your PMX880S and PMX660M is the built-
in multi-effects processor that features the same audio
quality as our renowned studio-grade VIRTUALIZER
PRO DSP2024P. The PMX880S even has two effects
processors, each of them with 99 different standard
effects such as reverb, chorus, flanger, delay, vocal
distortion as well as various effects combinations.
CATHEDRAL: Simulates the dense, long reverberation of a
large cathedral, which is appropriate for solo instruments or vocals
in slow pieces. Choose between two variations.
PLATE: Simulates the sound of plate reverberations and hence
is a classic for drums (snare) and vocals. The second one
features more high-end sparkle than the first.
CONCERT: Select between a small theater and a large hall.
Although this program is similar to studio (see below) it features
more presence, which adds to its lively character.
STAGE: Is well suited for dissipating the sound of a keyboard
or an acoustic guitar.
ROOM: You can clearly hear the walls of the room. A useful
program for reverb that isnt directly noticeable (rap, hip hop
vocals) or to make dry recordings of instruments sound natural
again.
STUDIO: This simulation of a middle to large-sized room is
also available in two variations. Both variations sound very
natural and can be used as all-purpose effects.
SMALL HALL: Simulates a small, lively (strongly reflecting)
hall and is perfect for processing drums.
AMBIENCE: Reproduces a middle-sized room without late
reflections.
EARLY REFLECTIONS: The initial reflections of this room are
clearly audible. This effect is a classic for dynamic signals (drums,
percussion, slap bass, etc.).
SPRING REVERB: Simulates classic spring reverberation.
GATED REVERB: This effect synthetically cuts off reverberation
after a period of time. It is famous in the song In the Air Tonight
by Phil Collins. The variations differ in the reverb length.
REVERSE REVERB: This is a reverberation in which the
envelope is reversed, i.e. it slowly gets louder.
CHORUS: This effect slightly detunes the original signal. A very
pleasant detune effect is created in connection with the pitch
variation. The chorus effect is used often and quite extensively
used for dispersing signals. The variations available range from
slow to fast chorus effects.
SYMPHONIC: This effect creates the sound of an eight-voice
(!) vocal chorus.
FLANGER: The word flange means tape spool, and this
explains the characteristics of the effect. Originally, the flanger
effect was generated with two tape recorders which ran
synchronously. The same audio signal was recorded on both
machines. If you put a finger on the left spool of one of the
machines, the spool and the playback speed are slowed down.
The generated delay results in phase shifting of the signals.
Please choose either medium flanger or one of the bright
flanger programs, which feature an increase in presence.
PHASER: With the phaser, a second, phase-shifted signal is
added to the original audio signal. The resulting sound is thicker
and above all livelier. This effect is often used for guitar sounds
and keyboards. In the 70s, it was also extensively used for
other instruments like electric pianos. The PMX offers you four
different phaser variations.
ROTARY SPEAKER: The simulation of a classic effect that is
normally generated with a (slow or fast) rotating speaker.
DELAY: A delay of the input signal with various repetitions.
Different tempo settings (ten variations in total) allow interesting
delay effects.
ECHO: Similar to the stereo delay, with the difference being
that the repetitions have less presence. This simulates the
character of the original tape echo that was used before the
digital era and can be thought of as a Vintage Sound.
MULTI TAP: A delay effect with changing stereo positioning
(left, center, right). Four variations are available.
CHORUS & REVERB: This algorithm combines the popular
chorus with a reverb effect. Taking all variations into account, they
differ in the length of reverb time.
FLANGER & REVERB: The combination of flanger and reverb
effects.
PHASER & REVERB: The combination of a classic stereo
phaser and a reverb effect. Here, too, the phaser is combined
with different reverb types.
ROTARY SPEAKER & REVERB: The combination of a rotary
speaker effect and reverb program.
DELAY & REVERB: Delay and reverb is the most common
combination for vocals, solo guitars, etc.
PITCH & REVERB: The pitch shifter slightly detunes the audio
signal, while the reverb adds ambience to the signal.
DELAY & CHORUS: Chorus can contribute to a wideness of
the signal and interesting repetition effects can be adjusted with
the delay. Vocals can be given a distinctive effect without making
the voice sounding blurred.
DELAY & FLANGER: This effect is just right for creating a
modern, slightly spacy vocal sound.
DELAY & PITCH: A repetition of the audio signal, with an
oscillatory effect added by the pitch shifter.
3 VOICE PITCH: The pitch effect can be used to produce a
cartoon-character type voice effect.
LFO BANDPASS: Filters, in general, influence the frequency
response of a signal. A low-pass filter allows low frequencies
to pass and suppresses high frequencies, while a high pass
filter allows high frequencies to pass and suppresses low
frequencies. This LFO bandpass effect is complemented by
modulation from an LFO (Low Frequency Oscillator).
VOCAL DISTORTION: This effect is very hip when used on
vocals and drum loops.
VINYLIZER: This effect adds clicks and noise to your audio
signal, simulating old vinyl records.

SPACE RADIO: Here, the typical sound of scanning an FM
tuner is simulated. This can be a very interesting effect when
sound-tracking radio plays.
TEST TONE: Use this 1-kHz test tone to facilitate P.A. level
setting.

4.3 Loudspea er connection
Your EUROPOWER is equipped with high-quality NEUTRIK
NL4FC SPEAKON® 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 SPEAKON® jacks carries only the
assigned single signal (see tab. 4.1/fig. 4.7 and the information
on the rear panel of the power mixer).

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.

EUROPOWER PMX660M/PMX880S
5. WIRING EXAMPLES
For stereo operation the POWER AMP switch of the
PMX880S must be set to its upper position (MAIN L/MAIN R).
Outputs A and B deliver the stereo main signal to the P.A.
speakers. Two active speakers, wired in parallel, are connected
to the PREAMP MONITOR output. They are used as on-stage
monitor speakers. The effects processors can be switched on
and off with a dual footswitch. This set-up is not possible with
the PMX660M (no stereo operation possible).

(example)
5. W R NG EXAMPLES
Both the PMX880S and the PMX660M can be set-up for dual
mono operations. The POWER AMP switch must be set to its
lower (PMX660M) or center position (PMX880S). The two
SPEAKON® outputs provide the main and the monitor signals
independently of each other and to two loudspeakers each,
which are wired in parallel.
