1 Operating Elements
and Connections

1.1 Front panel

1 Volume control for the chime
2 Sliding switch for switching the chime to the
output 1, 1 + 2 or 2
3 Button for activating the chime
4 Volume control, for each input 1 to 10
5 Sliding switch, for each input 1 to 10, for
switching the input to the output 1, 1 + 2 or 2
6 Signal indication SIG, for each input 1 to 10,
lights up when the input signal is applied,
independently of the corresponding control
LEVEL (4)
7 Switch PH. PWR, for each microphone input
2 to 10, to switch on the 15 V phantom power
(position ON)
For connecting a microphone or another
audio source with unbalanced signal to the
corresponding jack, switch off the phantom
power (position OFF) so that the audio
source will not be damaged.
To prevent loud switching noise, only actuate
the switch when the unit is switched off or the
volume is turned down.
8 Input level switch MIC / LINE for each input 2
to 10
Button disengaged:
for microphones
Button engaged:
for audio units with line output
(MP3 / CD player, tuner, mixer etc.)
For channels 7 to 10, the unit is switched over
between the corresponding XLR MIC input
jack (19) and RCA LINE input jack (18) at the
same time.
9 Priority switch for the inputs 2 and 3; when
the corresponding switch is in the lower posi-
tion (ON) and the input signal is applied, the
signals of channels 4 to 10 are muted for the
outputs to which channel 2 or 3 is switched
10 Level indication, for each output 1 and 2; in
case of overload the corresponding red LED
lights up
11 Tone controls BASS and TREBLE, for each
output 1 and 2
12 Volume control LEVEL, for each output 1
and 2
13 POWER switch with power LED (if a 24 V
emergency supply voltage is applied, the pre-
amplifier continues to operate even after
switching-off)

1.2 Rear panel

14 Mains cable for connection to a socket
(230 V~/50 Hz)
15 Screw terminals for an emergency supply
voltage of 24 V
16 Outputs 1 and 2 via balanced XLR jacks for
connection to the power amplifiers
6
17 RCA jacks REC for a recorder
white jack LEFT = mixed signal 1
red jack RIGHT = mixed signal 2
The level is independent of the volume con-
trols (12) of the outputs 1 and 2.
18 RCA inputs of channels 7 to 10 for audio units
with line output (CD player, tape deck, tuner
etc.)
19 XLR inputs* of channels 7 to 10 for micro-
phones
20 XLR inputs* of channels 2 to 6 for micro-
phones or for audio units with line output [to
be selected with switch MIC / LINE (8)]
21 RJ45 jack for connecting a PA PTT micro-
phone (e. g. PA-4000PTT from MONACOR)
22 Screw terminals for a momentary pushbutton
to activate the chime remotely
2 Safety Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit uses dangerous mains
voltage. Leave servicing to skilled
personnel only and do not insert
anything into the air vents. Inexpert
handling or modification of the unit
may result in electric shock.
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
The heat generated in the unit must be carried
off by air circulation. Therefore, do not cover
the air vents of the housing.
G
Do not set the unit into operation, and discon-
nect it from the power supply if:
1. there is visible damage to the unit or to the
mains cable,
2. a defect might have occurred after the unit
was dropped or suffered a similar accident,
3. malfunctions occur.
In any case, the unit must 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
for other purposes than originally intended, if it
is not correctly connected or operated, or not
repaired in an expert way.

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 yellow
must be connected to the terminal in the
plug which is marked with the letter E or by
the earth symbol
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.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment.
3 Applications
This mixing preamplifier is specially designed for
application in PA systems. It is connected ahead
of the PA power amplifier and allows connection
of up to 10 microphones (also phantom-powered
microphones). To the inputs 2 to 6, audio units
with line output can alternatively be connected.
To the inputs 7 to 10, audio units with line output
.
can additionally be connected; it is possible to
switch over to these units via input selector
switches. All inputs can separately be switched
to output 1, output 2 or to both outputs at the
same time.
A selectable priority circuit for the inputs 1 to
3 mutes the signals of the other channel so that
it is easier to understand important announce-
ments. In addition, a chime tone can be selected
to precede an announcement.
4 Setting-up
The unit is provided for insertion into a rack
(482 mm / 19"), but it can also be used as a table-
top unit. Air must always be able to circulate
without obstruction through all vents so that no
heat accumulation occurs inside the unit. For
installation into a rack, 1 rack space is required
(= 44.45 mm).
5 Connections
Prior to connecting units or changing the con-
nections, switch off the PA-1414MX and the
entire PA system.
5.1 Inputs
When connecting the microphones and the
audio units to the individual channels, take into
consideration that channels 1 to 3 can take pri-
ority over channels 4 to 10.
Channel 1: With activated priority circuit [switch
PRIORITY at the microphone in position ON],
the channels 4 to 10 are muted when the talk
button on the microphone is pressed.
Channels 2 and 3: With activated priority circuit
[switch PRI-2, PRI-3 (9)], as long as a signal is
present here, the signals of the channels 4 to 10
are muted for the outputs to which channel 2 or 3
is switched.
5.1.1 Microphones
Connect microphones to the jacks MIC IN -
PUT (19) and MIC / LINE INPUT (20). Disen-
gage the corresponding button MIC / LINE (8)
[position MIC].
If a microphone requires phantom power, set
the switch PH. PWR (7) to position ON.* Thus, a
phantom power of 15 V is applied to the corre-
sponding jack. To switch off the voltage, set the
*Caution! With the phantom power switched on [switch
PH. PWR (7)] do not connect any microphones or other
audio sources with unbalanced signals to the jack;
they may be damaged.
