Power Amplifier; Power Supply And Emergency Power Supply - Monacor PA-1414MX Mode D'emploi

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.
5.1.2 PA PTT microphone
Connect a PA PTT microphone (e. g. the desk
microphone PA-4000PTT from MONACOR) to
channel 1 via the RJ45 jack PA-4000PTT (21).
The maximum length of the connection cable
may be 30 m.
5.1.3 Audio units
Connect units with line output level (CD player,
tape deck, tuner, mixer etc.) and balanced output
signals to the XLR jacks MIC / LINE INPUT (20),
and engage the corresponding button MIC / LINE
(8) [position LINE]. For stereo signals, connect
each stereo channel to an individual input.
Connect units with unbalanced output sig-
nals to the RCA jacks LINE INPUT CH 7 to
CH 10 (18). Stereo signals at the respective
jacks LEFT and RIGHT are mixed in the unit to a
mono sum. With the corresponding selector
switch MIC/ LINE (8), it is possible to switch over
between the units connected to the RCA jacks
and the microphones connected to the XLR
jacks MIC INPUT (19).
Audio sources with unbalanced output sig-
nals may also be connected to the XLR jacks
(20) of channels CH 2 to CH 6 if an adapter with
the XLR contacts 1 and 3 bridged is used. In
order not to damage the audio source, the phan-
tom power must be deactivated for this jack in
any case [switch PH. PWR (7) = OFF]!
5.2 Momentary pushbutton
for remote control of the chime
To activate the chime at a distance from the
preamplifier, connections for a momentary push-
button are available. Connect the momentary
pushbutton to the screw terminals CHIME RE -
MOTE* (22).

5.3 Power amplifier

Connect a two-channel power amplifier or two
one-channel power amplifiers to the XLR jacks
OUTPUT 1 and 2 (16).
If only one PA zone is required, connect a
one-channel power amplifier to the jack OUT-
PUT 1, and set all sliding switches OUTPUT
(2, 5) to position "1".
5.4 Recorder
An audio recorder may be connected to the jacks
REC (17). The recording level is independent of
the adjustment of the controls LEVEL (12) for the
two outputs. The signal of output 1 is applied to
the white jack LEFT and the signal of output 2 to
the red jack RIGHT.
5.5 Power supply and
emergency power supply
For continuous operation of the amplifier in case
of power failure, connect a 24 V emergency power
supply (e. g. PA-24ESP from MONACOR) to the
screw terminals 24 V * (15).
Note: If the 24 V voltage of the emergency power sup-
ply is present at the connections 24 V , the PA-1414MX
cannot be switched off with the button POWER (13). In
case of a mains failure or when the button POWER is
actuated for switching off, the unit is automatically
switched over to emergency power supply.
Finally connect the plug of the mains cable (14)
to a socket (230 V~ / 50 Hz).
* To make connection easier, the screw terminals can
be disconnected from their plug-in connections.
6 Operation
To prevent howling and switching noise, leave
the PA-1414MX switched off up to operating
step 5).
1) Set all volume controls LEVEL (4) and the two
output controls LEVEL (12) to position "0".
2) For the channels 1 to 3 select the priority:
channel 1: on the connected PTT micro-
phone (PRIORITY = ON),
channels 2 and 3: with the switches PRI-2 /
PRI-3 (9). In the lower position ON, the prior-
ity is switched on.
3) With the sliding switch OUTPUT (5) select
separately for each channel to which output,
i. e. to which PA zone the respective channel
is to be switched:
output 1, 1 + 2 or 2.
4) For the channels CH 2 to CH 10, use the but-
ton MIC / LINE (8) to define the unit con-
nected:
Button disengaged:
for microphones
Button engaged:
for audio units with line output
(MP3 / CD player, tuner, mixer etc.)
For the channels CH 7 to CH 10, the button
MIC / LINE can also be used to switch be -
tween a microphone connected to the XLR
input (19) and a unit connected to the RCA
jacks (18).
5) Switch on the PA-1414MX with the POWER
switch (13). The power LED next to the but-
ton lights up. Switch on the PA system com-
pletely.
If an emergency power supply is con-
nected, the PA-1414MX is automatically
switched over to emergency power supply in
case of power failure.
6) Set the two output controls LEVEL (12) to
2
approx. ⁄ . Adjust the volume of the con-
3
nected microphones and audio units with the
respective controls LEVEL (4). Leave the
controls in position "0" for all channels not
used.
7) Adjust the sound for the two outputs sepa-
rately with the controls (11) BASS for the
bass frequencies and TREBLE for the high
frequencies.
8) Finally adjust the desired overall volume for
the outputs with the two controls LEVEL (12).
The green LED "0" of the level indication (10)
should only light up with music peaks. In case
of overload the red LED "+3" lights up. In this
case reduce the volume with the correspon-
ding control.
6.1 Chime
1) Set the chime with the sliding switch OUT-
PUT (2) to the output 1, 1 + 2 or 2.
2) Prior to an announcement the chime can be
activated with the button
additional momentary pushbutton connected
to the terminal CHIME REMOTE (22). While
the chime is activated, the channels 4 to 10
are muted for the outputs to which the chime
is applied.
3) Adjust the chime volume with the control
CHIME (1).

6.1.1 Selecting the chime tone and switching
on filters for the microphone inputs
The tone of the chime can be adjusted with the
jumper CHIME SEL (
position "2T":
position "4T":
position "SIR": siren
The jumper HPF can be used to switch on a low
cut filter (200 Hz high pass filter) for each micro-
phone input CH 2 to CH 10 in order to suppress
impact sound and other low-frequency noise
(position ON).
WARNING For adjusting the chime tone, the
6.2 PA PTT microphone PA-4000PTT
(available as a separate accessory)
The operating elements mentioned here are
located on the desk microphone PA-4000PTT.
1) For the chime to sound prior to an announce-
ment when activating the TALK button, set
the switch CHIME on the rear side to position
ON (lower position).
2) For the microphone to take priority over chan-
nels 4 to 10, set the switch PRIORITY to posi-
tion ON.
3) For an announcement, keep the TALK button
pressed and wait for the chime, if necessary.
