5.7 Amplifiers

Connect the power amplifiers for the four PA
zones to the XLR jacks OUT (16) . At these jacks,
the mixed signals for the respective zone are
available as balanced signals with line level .

5.8 Pushbutton for the chime

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 availa-
ble for selection ( ☞ chapter 5 .8 .1) . To trigger
the chime tone, connect a pushbutton to the
respective contact of the plug-in screw terminals
CHIME INPUT 1/ 2 / 3 / 4 (25) and the common
contact G, for example:
⑨ 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 .
WARNING The mixer must be opened for
this operation; therefore, it must
be performed by skilled person-
nel only! Prior to opening the
mixer, disconnect the mains plug from the
socket; otherwise, there will be risk of electric
shock!
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:
⑩ 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
failure, connect a 24 V emergency power supply
unit (e . g . PA-24ESP) 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 indi-
cator (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 .

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 ampli-
fiers connected to the PA-6040MPX .
After operation, switch off the power
amplifiers 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
control GAIN (23) located above the respec-
tive 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
control LEVEL of the respective input channel
to "0" .
6) Use the output controls Z1 – Z4 (9) to ad-
just the volume desired for the respective
PA zone .
CAUTION Never adjust a very high
speaker volume . Permanent
high volumes may damage
your hearing! Your ear will get
accustomed to high volumes which do not
seem to be that high any more after some
time . Therefore, 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 .
The LEDs −13, −8, −3, 0 dB and CLIP (3) in-
dicate the level of the respective output . The
LED CLIP will light up when the output is
overloaded . In this case, turn back the con-
trol (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 Chime

To activate a chime, e . g . to precede an an-
nouncement 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) .
Like announcement made via the inputs
CH1 – CH4, the input signals of the input chan-
nels of lower priority (CH5 and CH6) will be
muted during the chime .

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 is to be heard . Engage the
switches for the zones desired; disengage
the other switches .
2) Prior to the first announcement, turn the
volume 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 prior-
ity 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, be-
cause the priority of this microphone is de-
fined 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
sound first when the button TALK (31) is
pressed; the tone of the chime will be same
as the chime tone that is triggered by a push-
button connected to the mixer; the tone can
be selected in the mixer ( ☞
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 mi-
crophone 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
microphone .
