it is the culmination of
many months of hard
work delivered by our
engineering team to reach
a very ambitious goal:
to present you two
outstanding power
mixers that give you

performance with a unique sound character and broad range of
striking functions.

The task to design the new PMH series certainly meant a great
deal of responsibility, which we assumed by focusing on you,
the discerning user and musician. It also meant a lot of work and
night shifts to accomplish this goal. But it was fun, too. Developing
a product usually brings a lot of people together, and what a

the most important member of the BEHRINGER team. With your
highly competent suggestions for new products youve greatly
contributed to shaping our company and making it successful. In
return, we guarantee you uncompromising quality as well as
excellent technical and audio properties at an extremely
favorable price. All of this will enable you to fully unfold your
creativity without being hampered by budget constraints.

We are often asked how we can make it to produce such
high-grade devices at such unbelievably low prices. The answer
is quite simple: its you, our customers! Many satisfied customers
means large sales volumes enabling us to get better conditions
of purchase for components, etc. Isnt it only fair to pass this
benefit back to you? Because we know that your success is
our success, too!

I would like to thank all people whose help on Project PMH
has made it all possible. Everybody has made very personal

EUROPOWER PMH660M/PMH880S

1. INTRODUCTION

Congratulations! With the PMH660M/PMH880S 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 Voice 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 PMH 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 PMH power mixer.

1.1 Before you get started

1.1.1 Shipment

Your PMH was carefully packed at the factory and the
packaging is designed to protect the unit from rough handling.
Nevertheless, we recommend that you carefully examine the
packaging and its contents for any signs of physical damage
which may have occurred during transit.

+ If the unit is damaged, please do NOT return it to

BEHRINGER, but notify your dealer and the shipping
company immediately. Otherwise, claims for damage
or replacement may not be granted.

+ We recommend that you use a flight case, so as to give

your power mixer optimum protection during use or
transport.

+ Always use the original packing carton to prevent

damage during storage or transport.

+ Make sure that children cannot play unsupervised with

the device or its packaging.

+ Please ensure proper disposal of all packing materials.

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

type and rating! Please refer to the
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.

1.1.3 Warranty

The EUROPOWERs serial number is located on the rear panel.
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 PMH880S 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 note that the effects processor signal will

be inaudible when the FX RETURN control ( ) is
set fully counter-clockwise.

For the mono input channels, the PMH880S has a
PAN(ORAMA) control which determines the position of the
channel signal in the stereo main mix. The PMH660M 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
PMH880S 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 PMH660M has no stereo channels and hence
no BAL control, because it is a dual-mono power mixer.
