EUROPOWER PMH660M/PMH880S
2. CONTROL ELEMENTS
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 W 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).
