easier handling.
2 Safety Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with .
It is essential to observe the following items:
G
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity, and heat (admissible ambi-
ent temperature range 0 – 40 °C).
G
Do not place any vessels filled with liquid, e. g.
drinking glasses, on the unit.
G
Do not set the unit into operation, and imme-
diately disconnect the mains plug from the
mains socket if
1. there is visible damage to the unit or to the
mains cable,
2. a defect might have occurred after a drop or
similar accident,
3. malfunctions occur.
The unit must in any case be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug.
G
For cleaning only use a dry, soft cloth, never
use chemicals or water.
G
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used

Important for U. K. Customers!
The wires in this mains lead are coloured in
accordance with the following code:
green/yellow = earth
blue = neutral
brown = live
As the colours of the wires in the mains lead of
this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
1. The wire which is coloured green and yel-
low must be connected to the terminal in the
plug which is marked with the letter E or by
the earth symbol , or coloured green or
green and yellow.
2. The wire which is coloured blue must be
connected to the terminal which is marked
with the letter N or coloured black.
3. The wire which is coloured brown must be
connected to the terminal which is marked
with the letter L or coloured red.
Warning – This appliance must be earthed.
3 Applications
The mixer PA-4040MPX has especially been
designed for application in PA systems. It is pos-
sible to connect microphones (CH 1 to 3) or units
with line level output (CH 1 to 5) to the five
inputs. All inputs may be assigned to four PA
zones independent of each other. A headphone
output and a speaker output are provided to
monitor the zone output signals.
An additional line level input is provided for
emergency announcements or other important
announcements. A separate switch allows to
switch to this input.
4 Placing and
Connecting the Mixer
The mixer is provided for installation into a rack
for units with a width of 482 mm (19″) but it can
also be used as a tabletop unit. For installation
into a rack, 3 rs (rack spaces) = 133 mm are
required.
Prior to connecting units or changing exist-
ing connections switch off the mixer and the
units to be connected.
4.1 Microphones
Up to three microphones with XLR or 6.3 mm
plug may be connected to the inputs CH 1 to
CH 3 (25). Set the input level switches (20) to
the corresponding position. Only actuate the
switches with the mixer switched off or when the
corresponding control LEVEL (6) is set to zero
(switching noise).
MIC for microphones which do not require phan-
tom power.
PHANTOM for phantom-powered microphones
4.2 Units with line output
Up to five units with a line output (e. g. CD player,
cassette recorder, radio) may be connected to
the inputs CH 1 to CH 5 (24 and 25). The stereo
signals fed to the jacks “L” and “R” of the inputs
CH 4 and CH 5 are internally combined to a
mono signal.
When connecting to the inputs CH 1 to 3, set
the corresponding input level switch (20) to posi-
tion LINE. Only actuate the switch with the ampli-
fier switched off (switching noise). For connect-
ing a stereo unit to the inputs CH 1 to 3, use one
input each for the right stereo channel and the
Caution! With the 15 V phantom voltage
switched on, do not connect any microphones
with unbalanced output, as they may be dam-
aged.
WARNING The unit is supplied with haz-
ardous mains voltage. Leave ser -
vicing to skilled personnel only.
Inexpert handling of the unit may
cause an electric shock hazard.
Caution! Only actuate the switch when the
mixer is switched off or the corresponding
control LEVEL (6) is set to zero (switching
noise).
With the phantom voltage switched on, do
not connect any microphone with unbal-
anced output. The microphone may be dam-
aged.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which will not be
harmful to the environment.
