6.6.1 Status LEDs at the PA-4000RC
In addition to the LEDs BUSY and TALK described
above, the zone-paging microphone is equipped
with the following status LEDs:
POWER / CPU ERROR (40) – lights up as soon as
the supply voltage is available; it flashes in
case of a malfunction of the microprocessor
in the PA-4000RC
MIC FAULT / LOW VOLTAGE (41) – lights up
with a failure of the microphone, it flashes
if the supply voltage is too low; in case the
supply voltage is too low, the connection of
an additional power supply unit may help
( ☞ chapter 5 .5 .2, item 3)
SIGNAL (42) – lights up when a microphone
signal is available
EMER . (50) – (one for each PA zone)
light up when an emergency microphone
unit PA-4000FMP signals an emergency sit-
uation for the corresponding zone
6.6.2 Adjustments at the PA-4000RC
The DIP switch block (45) with the three switches
on the rear side of the desk microphone offers
the following functions:
CHIME – in position ON, a chime sounds first
when the TALK button (52) is pressed; the
sound of the chime is the same as if activated
via a momentary pushbutton connected to
the amplifier . It can be selected in the ampli-

fier ( chapter 5 .8 .1)
PRIORITY – in position ON, the PA-4000RC takes
priority over others without this function
activated and it is able to interrupt their
announcements
COMPRESSION – in position ON, the dynamic
power of the microphone signal is attenu-
ated and thus distortions are reduced when
talking at high volume
7 Protective Circuits and
Fault Indication
The output amplifiers of the PA-40120 are
equipped with protective circuits against over-
load and overheating to prevent damage to the
speakers and the amplifier . In case an output
amplifier fails in this way, a relay will switch the
100 V speakers to a connected reserve amplifier
☞
( chapter 5 .10) . The Protect LED (3) of the
output concerned lights up and a warning signal
sounds via the internal speaker (7) . In addition,
the relay FAULT (18) responds and is therefore
able e . g . to control an external warning facility .
Short lighting-up of all PROTECT LEDs when
switching on the amplifier is usual and does not
indicate any defect .
If a fault occurs at a connected emergency
microphone unit PA-4000FMP (e . g . at the hand-
held microphone of the microphone system),
likewise a warning signal sounds via the internal
speaker (7) and the relay FAULT (18) responds .
In addition, the LED EMER . FAULT (3) of the PA
zone the emergency microphone unit is assigned
to lights up .
In order to be able to hear the warning sig-
nal via the internal speaker (7), the speaker must
be switched on [switch SPEAKER (5) engaged] .
The control LEVEL (6) has no effect on the vol-
ume of the warning signal .
