1 Overview
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)
To connect a microphone or another audio
source with unbalanced signal to the cor-
responding jack, switch off the phantom
power (position OFF) so that the audio
source will not be damaged .
To prevent loud switching noise, only actu-
ate 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
preamplifier continues to operate even after
switching-off)

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
17 RCA jacks REC for a recorder
white jack LEFT = mixed signal 1
red jack RIGHT = mixed signal 2
6
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)
22 Screw terminals for a momentary pushbut-
ton 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 . In-
expert handling or modification
of the unit may result in electric
shock .
•
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) .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses, on the unit .
•
The heat generated in the unit must be carried
off by air circulation . Therefore, do not cover
the air vents of the housing .
•
Do not set the unit into operation, and dis-
connect 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 .
•
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug .
•
For cleaning only use a dry, soft cloth, never
use chemicals or water .
•
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 UK 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.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful 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-pow-
ered microphones) . To the inputs 2 to 6, audio
units with line output can alternatively be con-
nected . 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 out-
puts 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
announcements . 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 tab-
letop 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 any 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
available 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 INPUT
(19) and MIC / LINE INPUT (20) . Disengage the cor-
responding 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
switch to position OFF . To prevent loud switching
noise, only actuate the switch when the unit is
switched off or the volume is turned down .
* Caution! With the phantom power switched on
[switch PH . PWR (7)], never connect any microphones
or other audio sources with unbalanced signals to the
jack; they may be damaged .
