Operation; Specifications - Monacor PA-1414MX Bedienungsanleitung

5.1.2 PA PTT microphone
Connect a PA PTT microphone (e . g . the desk mi-
crophone PA-4000PTT) 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 out-
put 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
signals 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 be-
tween 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 phantom
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
pushbutton are available . Connect the momen-
tary pushbutton to the screw terminals CHIME
REMOTE* (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) to the screw ter-
minals 24 V⎓* (15) .
Note: If the 24 V voltage of the emergency power
supply is available 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 pri-
ority 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
button MIC / LINE (8) to define the unit con-
nected:
Bu tton disengaged:
for microphones
Bu tton 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 between
a microphone connected to the XLR in-
put (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
button lights up . Switch on the PA system
completely .
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
approx . ⁄ . Adjust the volume of the con-
2
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 sep-
arately 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
corresponding control .
6.1 Chime
1) Set the chime with the sliding switch OUTPUT
(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 sounds, 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": 2-tone chime
position "4T": 4-tone chime
position "SIR": siren
The jumper HPF can be used to switch on a
low cut filter (200 Hz high pass filter) for each
microphone 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
connect the mains plug from the socket before
opening the unit; otherwise, you will risk an
electric shock .
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
channels 4 to 10, set the switch PRIORITY
to position ON .
3) For an announcement, keep the TALK button
pressed and wait for the chime, if necessary .
