6 EUROPOWER PMP1680S/PMP980S/PMP960M User Manual 2. 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 HIGH 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 (32) ). The PMP980S/PMP1680S 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 (32) ). ◊ Please note that the effects processor signal will be inaudible when the FX RETURN control (21) is set fully counter-clockwise. (6) For the mono input channels, the PMP980S/PMP1680S has a PAN(ORAMA) control which determines the position of the channel signal in the stereo main mix. The PMP960M 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 PMP980S/PMP1680S 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 PMP960M 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 (¼" TRS) can be used for line-level 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 (27)). (13) Unbalanced stereo line inputs with ¼" connectors for stereo channels 7 to 10 of the PMP980S/PMP1680S. 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! 2.2 Effects section (14) List of all multi-effects presets. (15) LED level meter of the effects processor. Since the PMP980S/PMP1680S 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 (PMP980S/PMP1680S: two displays) shows the currently selected preset. (17) Turn the PROGRAM control (PMP980S/PMP1680S: 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 (PMP980S/PMP1680S: 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 PMP980S/PMP1680S 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 CD/TAPE IN control adjusts the volume of the 2 Track In signal (see (35) ). (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 PMP980S/PMP1680S 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) +48 V 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 PMP980S/PMP1680S 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 PMP960M 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 (Locking cable, pins 1+/2+). With the normal pin connections (Locking 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 (44) and (45) as well as chapter 4.4 "Loudspeaker connectors".

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  
(32)
). The PMP980S/PMP1680S has two FX controls (FX 1 and FX 2),
so that you can use two effects simulteneously. Accordingly, it also provides

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 PMP980S/PMP1680S 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
CD/TAPE IN
control adjusts the volume of the 2 Track In signal (see
(35)
).
(23)
The
MONITOR MASTER
control adjusts the monitor output volume.
(24)

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 PMP980S/PMP1680S 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)

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 PMP980S/PMP1680S 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 PMP960M 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 (Locking cable, pins 1+/2+). With the
normal pin connections (Locking 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.
