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 instal­
lation 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 plug or
6 .3 mm plug may be connected to the inputs
CH 1 to CH 3 (25) . Set the input level switches
(24) to the corresponding position . Only actuate
the switches when the amplifier is switched off
or when the corresponding control LEVEL (3) is
set to zero (switching noise) .
MIC for microphones which do not require
phantom power
PHANTOM for phantom­powered microphones
Caution! Do not connect any microphones
with unbalanced output when the phantom
power has been activated . These microphones
may be damaged .
4.2 Units with line output
Up to five units with a line output (e . g . CD
player, cassette recorder, radio) may be con­
nected to the inputs CH 1 to CH 5 (23 and
25) . For background music, it is best to use
the inputs CH 4 and CH 5 . These inputs may
be muted with a separate switch when e . g .
an announcement is made via the input CH 1
(see chapter 4 .4) . The stereo signals fed to the
jacks "L" and "R" of the inputs CH 4 and CH 5
are internally mixed to a mono signal .
When connecting to the inputs CH 1 to
CH 3, set the corresponding input level switch
(24) to the position LINE . Only actuate the
switch with the amplifier switched off (switch­
ing noise) . For connecting a stereo unit to the
inputs CH 1 to CH 3, use one input each for the
right stereo channel and the left stereo channel
or use a stereo mono adapter (e . g . SMC­1 from
MONACOR); otherwise, the signals of the ste­
reo centre will cancel each other out .

4.3 Connection for emergency announce-
For emergency announcements or for con­
nection to a telephone system, the amplifier
is provided with the input TEL PAGING (20) .
TEL. PAGING
T
Feed the signal (line level, 40 mV – 1 .5 V) via
a shielded audio cable to the terminal "R" .
Connect the ground and the shield to the ter­
minal "G" . Connect a switch to the terminals
"T" and "G" . The switch is used to release the
announcement, i . e . the announcement signal
may always be available at the terminal "R",
but it can only be heard when the switch is
closed . When the switch is closed, the signals
of the inputs CH 2 – 5 can be muted at the same
time, see chapter 5 .1
Set the DIP switches ZONE (21) for the
zones where the emergency announcements
are to be heard to the lower position ON . The
volume for these announcements is separately
adjusted with the control VOLUME (22) on the
rear side .
4.4 Switch for muting
The inputs CH 2 to CH 5 can be muted together
with a single switch, e . g . for making an im­
portant announcement via the input CH 1 . For
this purpose, connect a switch to the terminals
PRIORITY (19) .
Note: When an announcement is made via the input
CH 1, the inputs CH 2 to CH 5 will be automatically
muted if priority is given to the input CH 1, see chap­
ter 5 .1 .
4.5 Power amplifiers for the speakers
Connect the power amplifiers for the speakers
in the different PA zones to the balanced out­
puts LINE OUT (26) . If the input of the amplifier
to be connected is unbalanced, only connect
the input to the terminals "+" (signal) and "G"
(ground) . When connecting, the terminals can
be removed from their plug­in connections for
easier handling .

4.6 Monitor speaker and headphones
To be able to monitor the signals of the PA
zones, it is possible to connect an 8 Ω speaker to
the terminals MONITOR (18) and headphones
to the jack PHONES (7) .
4.7 Line output for another amplifier
or a recorder
The line output MIX OUT (17) can be used to
connect another amplifier or a recorder . At this
output, the signal of the PA zone is available
whose button MON (10) is pressed . If multiple
zones are selected at the same time, the corre­
sponding zone controls LEVEL (11) define the
mixing ratio of the zone signals . Use this output:
1 . To connect an amplifier if e . g . multiple mon­
itoring speakers are required .
2 . To connect a recorder for recording the sig­
nals of a single zone or multiple zones .
4.8 Power supply
Finally connect the supplied mains cable to
the mains jack (14) first and then to a socket
(230 V/ 50 Hz) .
To ensure continued operation of the mixer
after a mains failure, connect a 24 V emer­
gency power supply unit (e . g . PA­24ESP from
MONACOR) to the screw terminals 24 V ⎓ (16) .
Note: When the 24 V voltage of the emergency
power supply is available at the screw terminals
24 V ⎓, it will not be possible to switch off the mixer
by means of the POWER switch (13) . The mixer will
automatically switch to emergency power supply in
case of a mains failure or when it is switched off .

Setting into Operation

5.1 Giving priority to the inputs CH 1
and TEL PAGING
In the factory, the inputs CH 1 and TEL PAGING
(20) are adjusted in such a way that their signals
will be mixed with the other input channels .
When the jumper S701 inside the amplifier is
rearranged, the inputs CH 1 and TEL PAGING
will take priority over the inputs CH 2 – 5 . When
an announcement is made via the input CH 1
or TEL PAGING, the signals of CH 2 – 5 will be
automatically muted during the announcement .
WARNING For rearranging the jumper
S 701, the unit must be opened .
Only skilled personnel may
do this; inexpert handling
may result in electric shock .
1) Disconnect the mains plug from the socket .
2) Unscrew the housing cover .
3) Rearrange the jumper S701 from OFF to ON
(figure at the bottom of page 9) .
4) Fasten the housing cover again .
