1 Operating Elements
and Connections
1.1 Front panel
1 POWER switch
2 Power LED
For each of the eight PA zones separate LEDs
and operating elements are available which
allow different configuration of the zones:
3 Display to indicate the signal source selected
with the buttons SOURCE (9):
L1 - L8 = signals of the inputs LINE 1 - 4 (34)
and LINE / MIC 5 - 8 (36)
L = signal of the additional input (22)
or of the wall module connected
(ARM-880WP1, ARM-880WP3)
OF = none of these signals is selected (OFF)
4 LED MIC 1: lights up when a microphone
connected to the jack MICROPHONE 1 (40)
takes priority over other signal sources (auto-
matic talkover); switchable with the button
PRIORITY (10)
5 LED PAGE BUSY: lights up when an
announcement is made via the zone paging
microphone ARM-880RC connected
6 Mixing control MIC 1 for the level of a micro-
phone connected to the jack MICROPHONE 1
(40)
7 Mixing control SOURCE for the level of the
signal source selected with the buttons
SOURCE (9)
8 Control MASTER for the overall volume of
the zone
9 Buttons SOURCE for selection of the signal
source (
item 3)
After selection, press the button ENTER (14)
within 10 seconds to confirm.
10 Button PRIORITY to give priority to a micro-
phone connected to the jack MICROPHONE 1
(40) over other signal sources (automatic
talkover); with the priority function activated,
the LED MIC 1 (4) lights up
The adjustments for monitoring the PA zones via
the integrated speaker are made in the operating
panel MONITOR, in addition to other features:
11 Display to indicate the zone selected with the
button ZONE SELECT (12)
12 Button ZONE SELECT to select the zone to
be monitored
After selection, press the button ENTER (14)
within 10 seconds to confirm.
13 Level LEDs for the output signal of the
selected zone
14 Button ENTER to confirm a selection with the
buttons SOURCE (9), ZONE SELECT (12) or
BGM ALL (17)
15 Button ESC to interrupt a selection started
with the buttons SOURCE (9), ZONE
SELECT (12) or BGM ALL (17)
(to stop the flashing of the displays and to
switch back to the previous adjustment.)
16 Volume control MONITOR for the integrated
speaker
17 Button BGM ALL to select the same signal
source together for all zones
within 10 seconds to confirm.
18 Button PAGE ALL to give priority to a micro-
phone connected to the jack MICROPHONE 1
(40) over other signal sources together for all
zones
1.2 Rear panel
For easier handling when connecting, the green
screw terminals (19, 22, 29, 30, 36) can be
removed from their plug-in connections.
19 Output for the audio signal of the respective
PA zone for connection to a power amplifier
20 Tone controls for the respective zone
21 Connection for a wall module
22 Additional input for an audio signal (line level)
which only arrives at the corresponding zone
23 Control GAIN for adapting the zone output
level to the input sensitivity of the connected
amplifier or to adjust the maximum admissi-
ble zone volume
24 Control PAGE to adjust the volume in each
zone for the signals of the connected zone
paging microphones
[jacks PAGING MIC 1 and 2 (38)]
25 Button REMOTE WALL CTRL
Button pressed: The signal source for the
zone can only be selected via a connected
wall module
Button not pressed: The signal source can
only be selected at the matrix router.
26 Level control for the audio signal of the addi-
tional input (22) and for the audio signal of a
wall module connected to the jack (21)
27 Mains jack for connection to a socket (230 V~/
50 Hz) via the supplied mains cable
The support for the mains fuse is located
below the mains jack. Only replace a blown
fuse by one of the same type.
28 DIP switches to define the master unit and
the slave units when several units ARM-880
are interconnected to obtain additional PA
zones (
chapter 4.6)
IMPORTANT! At the master unit or when one
ARM-880 only is used in the system, the
switch MASTER must be in the lower posi -
tion ON and all other switches in the upper
position. Otherwise the signals of the inputs
LINE 1 - 4 (34) and LINE / MIC 5 - 8 (36) are
not routed to the zone outputs (19).
29 (Fire) alarm inputs
If the contact for one zone is connected to the
contact "G", a (fire) alarm signal sounds in the
zone and the indication AL flashes on the dis-
play (3). The alarm volume can be adjusted
with the control TONE OUTPUT (31).
Additionally or alternatively, a signal present
at the contact EMC IN of the terminal EMER-
GENCY (30) can be routed into the zone. The
signal volume can be adjusted with the con-
trol EMC INPUT (32).
30 Terminal strip EMERGENCY
Contacts BATT SUPPLY + and - for a 24 V
emergency power supply
Contacts COMMON and ALERT connected:
the alarm signal is converted into a pulsating
signal sound
Contacts COMMON and EVAC connected:
the alarm signal is converted into a rising
siren signal
