EUROPOWER PMH660M/PMH880S

The LEVEL control adjusts the channel signal level in the main mix.

2.1.1 Input section

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-Zinput (1/4" TRS) can be used for line- level signal sources, e.g. keyboards, electric guitars and basses.

Each channel has a balanced LOW-Zmicrophone 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 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

List of all multi-effects presets.

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.

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

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.

Press the FX IN button (PMH880S: 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 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 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 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.

+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 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 4.4 “Loudspeaker connectors”.

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 .

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.
