8.7 Zone paging microphone
PA-2400RC
To make announcements via a PA-2400RC:
1) Prior to the first announcement, use a
small screwdriver to turn the volume con-
trol MIC (50) located on the rear side of
the zone paging microphone approx . to
mid-position . Also set the volume control
(2) for the input 2 to mid-position for the
time being .
2) Use the buttons Z1– Z10 / Z 20 (54) to pre-
select the PA zones where the announce-
ment shall be audible . When a zone is se-
lected, the LED above the corresponding
button will light up .
To deselect a zone, press the appro-
priate button again; the corresponding
LED will extinguish . To select or deselect
all zones of a row, press the button ALL
CALL in the respective row . To reset a row
to its previous zone selection, press the
button ALL CALL again .
When the LED BUSY (55) flashes, an
announcement is being made via a differ-
ent zone paging microphone or via a desk
microphone PA-4300PTT . It is not possible
to make announcements via multiple zone
paging microphones at the same time . A
zone paging microphone of higher pri-
ority, however, will be able to interrupt
an announcement (for setting priorities
☞
chapter 8 .7 .3, "PRIORITY") .
3) Keep the button TALK (52) pressed, wait
for the chime to sound, if applicable
(
☞
chapter 8 .7 .3, setting "CHIME") and
then speak into the microphone cartridge
(51) . The LED indicator above the button
will light up; as long as the button TALK
is pressed, the amplifier will switch over
to the zone output selection made at the
zone paging microphone . The LED SIGNAL
(55) will light up when the chime or the
announcement is started . The input signals
at the amplifier that have a lower priority
will automatically be muted (
figure 5, chapter 3) .
4) If required, readjust the volume of the
announcement using the control of the
input CH 2 . When multiple zone paging
microphones are used, their volume can
be separately adjusted by means of the
controls MIC (50) . Use the control MASTER
(11) to adjust the total volume as desired .
Note: For the PA-2410Z, the functions described of
the input control CH 2 and of the control MASTER
as well as muting of other signals will only apply
when more than two zones have been selected (
chapter 8 .7 .1) .

8.7.1 Additional amplifier
in the PA-2410Z
An additional 60 W amplifier in the PA-2410Z
facilitates independent announcements via
the zone paging microphone PA-2400RC
provided that not more than two zones are
selected . Instead of the mixed signal from
the main amplifier, these announcements are
sent to the outputs of the zones selected .
Thus, it is possible to make an announce-
ment in one or two zones, whereas music,
for example, continues to be reproduced in
the other zones .
The following applies to these announce-
ments:
– The gain only depends on the setting of
the control REMOTE (33) and of the control
MIC (50) on the respective zone paging
microphone . The volume control (2) for the
input CH 2 and the control MASTER will not
affect the gain .
– It is not possible to adjust the tone .
– The signal will not be routed via the inser-
tion point PRE OUT / AMP IN (26) .
– The announcements will not be routed to
the outputs HIGH IMP (22), LOW IMP (21)
and REC (27) .
– An emergency message triggered via the
switching contact E / M MESSAGE CON-
TROL (25) will take priority .
– An announcement via a desk microphone
PA-4300PTT will take priority when its
switch PRIORITY has been set to ON .
– When a message stored in the PA-1120DMT
is called up at a PA-2400RC, it will always
be reproduced via the main amplifier .
When three or more zones have been select-
ed, the announcement will automatically be
routed via the volume and tone controls of
the input CH 2, the control MASTER and the
main amplifier .
8.7.2 Zone output group
In each PA-2400RC, any selection of zone
outputs can be saved and called up as a
☞
table in
group:
1) Use the buttons Z1– Z10 / Z 20 (54) to select
the zones that are to be included in the
group .
2) Keep the button RECALL (53) pressed; the
LED ON (55) starts flashing . Release the
button when the LED stops flashing . The
group is now saved .
3) To call up the saved group, briefly press
the button RECALL .
4) To return to the selection that was valid
before the group was called up, briefly
☞
press the button RECALL again .
8.7.3 Additional settings
at the PA-2400RC
The DIP switch block (48) at the rear of the
zone paging microphone provides the fol-
lowing options (ON = lower switch position):
PRIORITY – When the switch is in the posi-
tion ON, the PA-2400RC will take priority
over the other PA-2400RC for which this
function has not been activated and can
interrupt their announcements .
COMPRESSION – When the switch is in the
position ON, the dynamics of the micro-
phone signal will be attenuated to reduce
distortions when announcements at a high
volume are being made .
CHIME – When the switch is in the position
ON, a chime will sound when the button
TALK (52) is pressed; the chime melody is
selected by means of the following two
switches .
4 TONE – When the switch is in the position
ON, the 4-tone chime will sound .
2 TONE – When the switch is in the position
ON, the 2-tone chime will sound provided
that the switch "4 TONE" is in the upper
position .
To adjust the volume of the chime, turn the
control CHIME (49), using a small screwdriver .
9 Protective Circuits and
Fault Indication
The power amplifier of the PA-2410Z and
PA-2420Z is equipped with a protective circuit
against overload and overheating to prevent
damage to the speakers and the amplifier .
When the LED PROTECT (10) lights up, the
protective circuit has been activated and a
fault has occurred . In this case, switch off the
amplifier and eliminate the source of error .
For the zone paging microphone PA-2400RC,
microphone failures will be indicated by the
LED MIC FAULT (55) .
