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.

1.2 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.

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

1. The HI control in the EQ section governs the high-frequency range of the respective channel.

2. Use the MID control to boost or cut the mid-range frequencies.

3. The LOW control allows you too boost/cut the low-frequency range.

4. With the MON control you can adjust the volume of each channel in the monitor mix.

5. 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  simultaneously. 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.

6. 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.

7. The BAL(ANCE) control for the stereo channels of the PMH880S corresponds 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.

8. The LEVEL control adjusts the channel signal level in the main mix.
   2.1.1 Input section

9. The CLIP LED is very useful to control the input gain. It should never be constantly illuminated (only with signal peaks).

10. The PAD switch reduces the input sensitivity of the channel by approx. 30 dB, to connect for example line-level signals.

11. The balanced HI-Z input (1/4″ TRS) can be used for linelevel signal sources, e.g. keyboards, electric guitars and basses.

12. Each channel has a balanced LOW-Z microphone input with XLR connectors, which also supply the +48 V phantom power for condenser microphones (see ).

13. Unbalanced stereo line inputs with 1/4″ connectors for stereo channels 7 to 10 of the PMH880S. They can be used for connecting keyboards with stereo outputs or stereo drum machines.
    Please remember to use either the microphone or the line input of a channel at a time, but never both at the same time!
    When you connect mono line-level signals to channels 7 to 10 of the PMH880S, always use the left input. The mono signal will then be reproduced by both stereo sides. 2.2 Effects section

14. List of all multi-effects presets.

15. LED level meter of the effects processor. Since the PMH880S 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.

16. The EFFECT display (PMH880S: two displays) shows the currently selected preset.

17. Turn the PROGRAM control (PMH880S: 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.

18. Press the FX IN button (PMH880S: FX 1 IN and FX 2 IN) to activate the effects processor.
    2.3 Main and monitor section

19. 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.

20. 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.

21. Turn the FX RET control to add the effect signal to the main mix (lower) or monitor mix (upper). The PMH880S 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 counterclockwise, no effect signal is added.

22. The 2TR IN control adjusts the volume of the 2 Track In signal (see ).

23. The MONITOR MASTER control adjusts the monitor output volume.

24. 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.

25. The MAIN MASTER control is used to adjust the main output volume.

26. Use this 5-digit LED meter to control the output level of the main signal. The PMH880S 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.

27. +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.

28. Use the POWER AMP switch to determine the operating mode of your power mixer.
    The PMH880S 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 PMH660M 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 “Loudspeaker connectors”.
    In BRIDGE mode, always connect only one loudspeaker with an impedance of at least 8 ΩΩΩΩΩ to OUTPUT B (pins 1+/2+)! Please note that OUTPUT A must NEVER be used in BRIDGE mode (with pin connections 1+/2+)!
    In all other operating modes, the minimum impedance of the speaker connected must not fall below 4 Ω.

29. 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.

30. If STANDBY 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 35). There is also no need to move down the faders of muted channels and lose your mix.
    2.3.1 Connectors

31. 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 PMH880S, 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.

32. 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 PMH880S has two FX controls per input signal (see 5) and also two FX OUT connectors (FX OUT 1 and FX OUT 2).
    Please note: When you connect a mono plug to one of the FX OUT jacks, the signal path from the respective FX send to the built-in effects processor is interrupted. For each FX send you can either use the built-in effect or  the corresponding FX OUT jack (for an external effect), but never both at the same time. When you use a stereo plug (tip and ring interconnected) you can use the built-in effects processor and the FX OUT jacks in parallel.

33. 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 PMH660S has only one mono AUX IN connector.

34. The AUX IN control adjusts the volume of the external signal in the main mix.

35. 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.

36. 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.

37. The REC OUT (RCA) provides line-level signals from the power mixer to a DAT recorder, for example. On the PMH880S the REC OUT signal is stereo and on the PMH660M two identical mono signals are provided.
    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!

38. 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 repower stage of the mixer. It is also possible to use only the left  jack of the output. The PMH660M has only one mono output connector.

39. 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.

40. 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 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.
    2.4 Rear panel

41. The mains connection is on a standard IEC receptacle. An appropriate power cord is supplied with the unit.

42. 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”.

43. These are the two cooling fans of the unit.

44. Loudspeaker OUTPUT A.
    PMH880S: 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.
    PMH660M: 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 of the loudspeaker connected must not fall below 4 Ω.
    Please note that the power delivered to the speaker in bridged mono mode is considerably higher than in other operating modes. Please read the information given on the rear panel of the power mixer.

45. Loudspeaker OUTPUT B.
    PMH880S: 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.
    PMH660M: 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 also refer to chapter 4.4 “Loudspeaker connection”.
    In BRIDGE mode, always connect only one loudspeaker with an impedance of at least 8 ΩΩΩΩΩ to OUTPUT B (pins 1+/2+)! Please note that OUTPUT A must NEVER be used in BRIDGE mode (with pin connections 1+/2+)!
    In all other operating modes, the minimum impedance of the speaker 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).

46. SERIAL NUMBER. 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.

DIGITAL EFFECTS PROCESSOR

A special feature of your PMH880S and PMH660M is the built-in multi-effects processor that features the same audio quality as our renowned studio-grade VIRTUALIZER  PRO DSP2024P. The PMH880S even has two effects processors,  each of them with 99 different standard effects such as reverb, chorus, flinger, 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 flinger 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 flinger” or one of the “bright flinger” 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 PMH 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.

INSTALLATION

4.1 Mains connection

Blown fuses must be replaced by fuses of the same type and rating.
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 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. Of course, all inputs and outputs work with both balanced and unbalanced connectors. The Tape  Ins and Outs are on stereo 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.

Please use a dual footswitch for the PMH880S, 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.

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. 4.7 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.

WIRING EXAMPLES

For stereo operation the POWER AMP switch 28 of the PMH880S 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 PMH660M (no stereo operation possible).

Both the PMH880S and the PMH660M can be set-up for dual mono operations. The POWER AMP switch 28 must be set to its lower (PMH660M) or center position (PMH880S). The two loudspeaker outputs provide the main and the  monitor signals independently of each other and to two loudspeakers each, which are wired in parallel.

This illustration shows just one example of how the channels of your power mixer can be used, including the connection of mono and stereo sources, and the tape ins and outs recording the mix signal or playing back external signals.

One example of how to use your power mixer with a subwoofer in bridged mono mode. The illustration shows the PMH880S with a subwoofer connected to OUTPUT B that will receive the full (bridged) output power. A separate stereo  power amp (BEHRINGER EUROPOWER EP1500) for the stereo main P.A. signal is connected to the PRE AMP MAIN outputs. The PRE AMP MONITOR output is wired to active speakers on the stage. This application can also be  realized with the PMH660M, except for the main P.A. signal, which would be mono.
