5.8 Pushbutton for chime triggering
A normally open contact can be used to add a
chime tone to the signals of each of the inputs
CH1 to CH4. Three different tones are available
for selection (
chapter 5.8.1). To trigger the
chime tone, connect a pushbutton to the respec-
tive contact of the plug-in screw terminals
CHIME INPUT 1/ 2/ 3/ 4 (25) and the common
contact G, for example:
Connection of the chime pushbutton
5.8.1 Selecting the chime tone
The chime tone can be set inside the mixer. A
2-tone sequence, a 4-tone sequence and a siren
tone are available. The siren tone is an emer-
gency tone according to DIN 33 404/ EN 457.
1) Remove the housing cover from the mixer.
2) In the rear section, parallel to the rear side of
the unit, a circuit board with jumpers is
located near the inputs for CH1 and PAGING.
Rearrange the jumper to the position of the
tone desired:
Selection of the chime tone
3) Close the housing again.
5.9 Power supply and
emergency power supply
To ensure continued operation after a mains fail-
ure, connect a 24 V emergency power supply
unit (e. g. PA-24ESP from MONACOR) to the
terminals 24 V (15). Finally, use the mains
cable provided to connect the mains jack (13) to
a socket (230 V~ /50 Hz).
Note: When a voltage of 24 V is available, the mixer will
immediately be in operation and the power indicator
(11) will light up. The mixer cannot be switched off with
the switch POWER (12). This switch can only be used
to switch from mains power supply to emergency power
supply.
6 Operation
1) To prevent an excessive volume, turn the
output controls Z1 – Z4 (9) to “0” prior to
switching on the mixer for the first time.
2) First, switch on the audio sources connected
and, with the switch POWER (12), the PA-
6040MPX. The power indicator (11) will light
up. Finally, switch on the power amplifiers
connected to the PA-6040MPX.
After operation, switch off the power ampli-
fiers first.
3) For the basic settings, set the controls for the
inputs LEVEL (8) and the tone controls (1) to
mid-position for the time being.
4) Turn the controls for the outputs used Z1 – Z4
(9) clockwise so that the subsequent settings
can be easily heard via the speakers.
5) Use the switches Z1 – Z4 (2) to define for
each input to which outputs (i.e. PA zones) its
signal shall be routed. The LED SIG (7) will
light up when a signal is available. If the LED
does not light up, increase the output level of
the audio sources or readjust the input gain
for the channels CH1 to CH4, using the con-
trol GAIN (23) located above the respective
input jack.
Use the respective volume controls
LEVEL (8) to mix the input signals or to mute
or unmute them as required.
If an audio source is not used, set the con-
trol LEVEL of the respective input channel to
“0”.
6) Use the output controls Z1 – Z4 (9) to adjust
the volume desired for the respective PA
zone.
The LEDs −13, −8, −3, 0 dB and CLIP (3)
indicate the level of the respective output.
The LED CLIP will light up when the output is
overloaded. In this case, turn back the control
(9) of the output accordingly or reduce the
volume of the respective input signal with the
control LEVEL (8).
7) Adjust the tone with the controls (1) TREBLE
for the high frequencies and BASS for the low
frequencies. Then readjust the volume, if
required.
6.1 Checking the outputs
The signals of the outputs can be checked by
means of a monitoring system connected to the
jack MONITOR (20).
1) Use the rotary switch REC /MONITOR (5) to
select the output to be checked. In the posi-
tion OFF, no output is selected.
2) Use the control LEVEL (6) to adjust the vol-
ume desired.
Note: The output jacks REC (19) will receive the same
signal as the jack MONITOR (20).
6.2 Triggering the chime
To activate a chime, e. g. to precede an
announcement to be made via one of the chan-
nels CH1 – CH4, briefly press the respective
pushbutton connected to the terminals (25)
(
chapter 5.8). The chime tone will be added
to the input signal; its volume, however, does not
depend on the control LEVEL (8) of the input
channel but only on the volume adjustment of
the output (9).
As with an announcement made via the
inputs CH1 – CH4, the input signals of the input
channels of lower priority (CH5 and CH6) will be
muted.
6.3 Desktop microphone PA-4000PTT
For announcements with this desktop micro-
phone:
1) Use the switches PAGING / PTT Z1 – Z4 (4) at
the mixer to select the PA zones where the
announcement shall be audible. Engage the
switches for the zones desired; disengage
the other switches.
2) Prior to the first announcement, turn the vol-
ume control PAGING / PTT LEVEL (10) at the
mixer approx. to mid-position.
3) Keep the talk button TALK (31) on the micro-
phone pressed and speak into the micro-
phone cartridge (29). The LED indicator (30)
will light up. If a specific speech volume is
exceeded, the input signals of lower priority
at the mixer will automatically be muted
(
table fig. 5 in chapter 3).
4) If required, use the control LEVEL-PAGING /
PTT to readjust the volume of the announce-
ment. The volume controls for the outputs (9)
will have no effect here.
6.3.1 Settings at the PA-4000PTT
Two small switches are located on the rear side
of the desktop microphone:
PRIORITY – for usage at the PA-6040MPX,
leave this switch in the upper position,
because the priority of this microphone is
defined in the mixer (when an announcement
is made or a chime sounds, the other input
signals will be muted so that the announce-
ment is easier to understand)
CHIME – in the position ON, a chime will first
sound when the button TALK (31) is pressed;
the tone of the chime will be same as the
chime tone that is triggered by a pushbutton
connected to the mixer; the tone can be
selected in the mixer (
chapter 5.8.1)
6.4 Announcement via the input
PAGING
For announcements via a unit connected to the
input PAGING (26) (e. g. microphone with pre-
amplifier or the line level output of a telephone
system), proceed as described in chapter 6.3.
The settings will apply both to the desktop micro-
phone PA-4000PTT and to the input PAGING. A
signal at the input PAGING will also mute the
input signals of lower priority; if an announce-
ment via the desktop microphone is made at the
same time, the signal at the input PAGING will
be mixed with the signal of the desktop micro-
phone.
6.5
Zone paging microphone PA-4000RC
For announcements with a PA-4000RC:
1) Prior to the first announcement, turn the vol-
ume control AUDIO LEVEL (44) on the rear
side of the zone paging microphone approx.
to mid-position.
2) Use the buttons beneath Z1 to Z4 (41) to pre-
select the PA zones in which the announce-
ment shall be audible. For the zones
selected, the LED BUSY next to the respec-
tive button will light up.
To deselect a zone, press the respective
button again so that the LED BUSY will extin-
guish. To select or deselect all zones, press
the button ALL CALL (42).
CAUTION Never adjust the speakers to a
very high volume. Permanent
high volumes may damage
your hearing! Your ear will get
accustomed to high volumes
which do not seem to be that
high after some time. There-
fore, do not further increase a
high volume after getting used
to it.
To prevent feedback noise, do not hold a
microphone towards a speaker or too close
to it. Likewise, feedback noise may occur
when the volume adjustment of the speak-
ers is too high. In this case, attenuate the
microphone volume, using the respective
control LEVEL.
WARNING The mixer must be opened for this
operation; therefore, it must be
performed by skilled personnel
only! Prior to opening the mixer,
disconnect the mains plug from
the socket; otherwise, there will
be risk of electric shock!
