Dear Customer,

Welcome to the team of EUROPOWER users and thank you very much for expressing your confidence in BEHRINGER products by purchasing this power mixer.

It is one of my most pleasant tasks to write this letter to you, because 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 maximum flexibility and

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 great feeling it is when everybody who participated in such a project can be proud of what we’ve achieved.

It is our philosophy to share our joy with you, because you are 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 contributions, starting from the designers of the unit to the many staff members in our company and finally to you, the user of BEHRINGER products.

My friends, it’s been worth the trouble!

Thank you very much,





h is ymbol imshhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh




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

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 The product-related information pages and the ULTRANET-based glossary explain the relevant audio engineering terminology in full detail.


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.
