EUROPOWER PMH660M/PMH880S

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 ). 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 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.

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 ) 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.

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.

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 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!

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 PMH660M 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 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

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.

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.

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 Ω 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).
