7 Operation
7.1 Adjusting volume and sound
To increase or reduce the volume for a zone,
turn the corresponding control ZONE (8) up
or down . To readjust the sound for a zone,
use the corresponding controls (5): HIGH for
the high frequencies, LOW for the low fre-
quencies .
If the volume of an input signal is too high
or low in relation to the volume of other input
signals, readjust the volume by means of the
corresponding control CH . . (2) . The sound of
an input signal in the channels CH 1 – 4 can
be adjusted by means of the controls HIGH,
MID and LOW (1) .
Important:
The settings for an input signal
will apply to all zones to which the input
signal has been switched .
7.2 Changing input signals for
the zones
If other signals than the ones currently se-
lected are to be audible in the zone:
1) In all input channels, disengage the corre-
sponding zone button Z . . (4) for the zone
(e . g . to change the selection for zone 2,
disengage the buttons Z 2) . Thus, all sig-
nals for the zone are deselected for the
time being .
2) Press the zone buttons Z . . in the input
channels whose signals are to be audible
in the zone .
3) If required, readjust the volume for the
zone by means of the corresponding con-
trol ZONE (8) .
7.3 Muting zones
If a zone is not to be provided with sound
(e . g . during intervals or at the end of an
event), the sound can be muted by means of
the corresponding button MUTE (7) .
Muting the sound of a zone can also be
useful when input signals are being selected:
Even when the sound of a zone is muted,
the sound can be monitored via the monitor
speaker (12), see chapter 7 .4 . Thus it is pos-
sible to make tests by switching input signals
to a zone without them being audible there .
7.4 Monitoring zone signals
A monitor speaker (12) is available so that
zone signals can be directly monitored at the
amplifier:
1) Use the switch PFL/AFL (9) to make the
appropriate selection:
PFL = The zone signals will be audible via
the monitor speaker even when the button
MUTE (7) is pressed or when the volume
control ZONE (8) is set to minimum .
AFL = The signals will be audible according
to the zone volume adjusted .
2) Engage the zone button Z . . (10) of the
zone to be monitored . Disengage the
other zone buttons (10) .
3) Use the control MONITOR (11) to adjust
the volume for the monitor speaker .
7.5 Zone paging microphone
PA-M4RC
Connect the microphone to the amplifier and
then, to make the basic settings, turn the
control (32) on the rear of the microphone to
mid-position and set the sliding switch (34) to
the position UNLOCK . As soon as the ampli-
fier is switched on, the LED indicator POWER
(36) will light up .
1) First use the zone buttons 1 … 4 (39) to
select the zones in which the announce-
ment shall be audible . To select all zones,
press the button ALL (38); to deselect a
zone, press a button again .
Note:
Please note the different lettering of the
microphone for the zones: the digits 1 and 2
to the left of the buttons apply to the amplifier
PA-M224, the digits 1 – 4 to the right of the
buttons apply to the amplifier PA-M412 .
2) Press the button CHIME (40) if the an-
nouncement is to be preceded by a chime
tone .
3) To make an announcement, keep the but-
ton TALK (41) pressed, wait for the chime
tone (if applicable) and then speak into
the microphone . The LED indicator CLIP
(35) should only light up briefly . If it lights
up more frequently, turn the control (32)
counter-clockwise accordingly, speak at a
lower volume or increase the distance to
the microphone .
If the volume of the announcement is
too low, turn the control clockwise accord-
ingly, speak at a higher volume or reduce
the distance to the microphone .
4) After the announcement, release the
button TALK; the zone selection will be
deleted; the zones must be selected again
for the next announcement .
Note:
Announcements made via the zone paging
microphone will take priority over other signals and
will interrupt them .
7.5.1 Saving a zone selection for
further announcements
1) Select the zones by means of the buttons
(38, 39) .
2) Set the sliding switch (34) to the position
LOCK . It will not be possible to change the
zone selection .
3) To make an announcement, keep the but-
ton TALK (41) pressed . When the button
TALK is released, the zone selection will
remain saved, the corresponding zone but-
tons will remain illuminated . The selection
will also remain saved when the amplifier
is switched off .
To change a zone selection saved:
1) Set the sliding switch (34) to the position
UNLOCK .
2) Use the buttons (38, 39) to select and de-
select zones .
3) To save a zone selection changed, set the
sliding switch (34) to the position LOCK
again .
7.6 Wall module PA-M1WP
As soon as the module is connected to the
amplifier and the amplifier is switched on,
the LED indicator ACTIVE of the module will
light up .
1) Use the button (28) of the module to make
the appropriate selection:
− The signals of a microphone or audio
unit (CD player, radio, etc .) connected
to the module are to be audible in the
zone: Engage the button; the LED in-
dicator ACTIVE will light up in yellow .
− The signals selected at the amplifier by
means of the buttons Z . . (4) are to be
audible in the zone: Disengage the but-
ton; the LED indicator ACTIVE will light
up in green .
2) Use the control VOL (30) to adjust the
volume for the zone . If it is not possible
to adjust a sufficiently high volume, turn
up the corresponding control ZONE (8) at
the amplifier which defines the maximum
volume possible .
7.7 Malfunctions
If the amplifier stage of a zone is overheated
or overloaded, the protective circuit will inter-
rupt the signal path to the speaker terminal
SPEAKER (20) in this zone . In this case, no
signal will be audible in the zone and the
corresponding LED indicator PROT (6) will
light up .
Use the corresponding control ZONE (8)
to reduce the zone volume . If the LED indica-
tor PROT fails to extinguish after the amplifier
stage has cooled down, ask skilled personnel
to find and eliminate the fault .
