3 Applications

The ARM-880 is an audio signal matrix router which allows to route eight different audio sources (microphones, MP3 / CD player, tuner, PC, etc.) to eight PA zones as desired. By interconnecting four ARM-880 units the system can be extended to 32 zones. A power amplifier for the speakers is required for each zone.

Numerous connections are available for further functions:

• 2 inputs for the zone paging microphones ARM-880RC which allow to make announcements only to certain zones or to all zones
• 1 connection for each zone for a wall module ARM-880WP... for remote control of the zone and /or for feeding an audio signal to the zone
• 1 additional input for each zone for an audio signal routed to the corresponding zone only
• 1 microphone input whose signal can be routed to all zones, with priority function to be activated
• 1 input, e. g. for an emergency signal that is routed to all zones and interrupts other signals
• 1 alarm input for each zone to trigger an alarm signal in the zone
• Connections for a 24 V emergency power supply unit

4 Setting Up and Connecting the Matrix Router

The ARM-880 is designed for insertion into a rack for units with a width of 482 mm (19"), but it can also be used as a table-top unit. For installation into a rack 3 RS (rack spaces) = 133 mm are required.

Prior to connecting units or changing existing connections switch off the matrix router and the units to be connected. All connections should only be made by qualified personnel.

For easier handling when connecting, the green screw terminals (19, 22, 29, 30, 36) can be removed from their plug-in connections.

4.1 Audio units with line output

To be able to route signals of audio units with line output (e. g. radio, MP3 / CD player, tape deck, PC) to the PA zones as desired, use the inputs LINE 1 – 4 (34) and LINE/ MIC 5 – 8 (36). RCA jacks are available for the inputs LINE 1 – 4 and screw terminals for the inputs LINE / MIC 5 – 8. When connecting an audio unit to the screw terminals, set the corresponding switch (37) to position LINE.

For routing the signals of an audio unit exclusively to a certain zone, the additional screw terminal input (22) can also be used which is available for each zone.

The screw terminals are designed for balanced signals. For an unbalanced connection feed the signal to the contact + and connect the contacts - and GND to the signal ground.

4.2 Microphones

When connecting several microphones, these microphones may receive a different priority, i. e. an announcement made via a microphone of high priority may automatically interrupt an announcement made via a microphone of lower priority.

Highest priority is given to the zone paging microphones ARM-880RC which allow to make announcements in certain zones only or in all zones. Two zone paging microphones may be connected to the jacks PAGING MIC 1 and 2 (38). For this purpose, a network cable (e.g. Cat 5 cable) with RJ45 plugs is required. For power supply connect the power supply unit provided to the jack 24 V= (47) and to a mains socket (230V/50Hz).

Medium priority is given to a microphone connected to the jack MICROPHONE 1 (40). The microphone signal can be routed into the zones and volume-adjusted by the controls MIC 1 (6). For priority of this microphone signal over the signals of the inputs LINE 1 – 4 (34) and LINE / MIC 5 – 8 (36), after switching on the matrix router, press the buttons PRIORITY (10) of the corresponding zones. The function can also be activated and deactivated together for all zones with the button PAGE ALL (18).

Note: The priority adjustment is not stored when switching off the matrix router and must be made again, if required, after switching on the matrix router again.

Lowest priority is given to microphones connected to the screw terminals of the inputs LINE/MIC 5–8(36).

The screw terminals are designed for balanced signals. For an unbalanced connection feed the signal to the contact + and connect the contacts - and GND to the signal ground.

If the microphone requires a phantom power (46 V), set the corresponding switch (37) to position PHANTOM. For microphones which do not require any phantom power, set the switch to position MIC.

4.3 Alarm inputs

For each zone, a contact (1 – 8) for alarm triggering is available at the screw terminal FIRE ALARM (29). If this contact is connected to the contact "G" via a corresponding switch, a (fire) alarm signal sounds in the zone and the indication "AL" flashes on the display (3). If the wall module ARM-880WP1 or ARM-880WP2 is connected, "Er" is indicated there. Adjust the alarm volume for all zones with the control TONE OUTPUT (31). The alarm signal has highest priority and interrupts all other signals in the zone.

Instead of the fire alarm signal a pulsating signal sound or a rising siren signal may sound. Connect the contacts ALERT and COMMON of the terminal EMERGENCY (30) for a pulsating signal sound or the contacts EVAC and COMMON for a rising siren signal.

4.4 Audio signal for all zones

If an (emergency) signal with line level is to be routed to all zones, feed the signal to the contacts EMC IN and GND of the terminal EMERGENCY (30). As soon as the signal is present at these contacts, it will be routed to all zones. Other signals will be interrupted and the indication "AL" will flash on the displays (3). The signal volume for all zones can be adjusted with the control EMC INPUT (32).

4.5 Wall modules

Each PA zone can be remote-controlled by connection of the wall module ARM-880WP1 or ARM-880WP2. For remote feed-in of an audio signal into a zone the wall module ARM-880WP1 or ARM-880WP3 can be used.

Connect the RJ45 jack "Net Interface" on the rear side of the module via a network cable (e. g. Cat 5 cable) with RJ45 plugs to the jack REMOTE WALL CTRL (21) of the corresponding zone. The power supply of the wall modules is made via the matrix router. However, for cable lengths exceeding 50 m use a power supply unit (= 24 V, current rating of 500 mA) to be connected to the contacts 24 V- and GND of the screw terminal on the rear side of the module.

Press down the button REMOTE WALL CTRL (25) for zones a wall module is connected to. Otherwise the zone cannot be remote-controlled with the module. For models ARM-880WP1 and ARM-880WP2, "OF" will be indicated on the display (63).

4.6 Power amplifier or active system

A balanced output signal for each zone is present at the screw terminals OUTPUT (19). In each case connect the input of a power amplifier for the speakers to this terminal. If the amplifier is provided with an unbalanced input only, connect it to the contacts + (signal) and GND (ground) only. Alternatively, active speaker systems may be connected to the zone outputs.

4.7 Extension of the system to up to 32 zones

If eight PA zones are not sufficient, the system can be extended to 16, 24 or 32 zones by using up to three further matrix routers ARM-880.

Note: Thus, the number of inputs capable of routing is not increased. Only the signals of the inputs LINE 1 – 4 (34) and LINE / MIC 5 – 8 (36) of the master unit can be routed as desired to all zones available. However, the additional inputs (22) for each zone and the alarm inputs (29) at each ARM-880 can be used. A wall module may be connected to each further zone.

1) Connect the terminal EXTENSION LINK OUT (33) of the master unit (at which all signals to be distributed as desired are present) to the terminal EXTENSION LINK IN of an additional matrix router ARM-880 (= slave unit) via the supplied cable.

2) The DIP switch MASTER (28) at the master unit must be set to the lower position ON. All other DIP switches must be in the upper position.

3) Set the DIP switch SLAVE 1 at the (first) slave unit to the lower position ON. All other DIP switches must be in the upper position.

4) A second slave unit may be connected to the first in the same way and a third to the second slave unit. Set the DIP switch SLAVE 2 at the second slave unit and the DIP switch SLAVE 3 at the third slave unit to the lower position. All other DIP switches must be in the upper position.

5) If the zone paging microphones ARM-880RC are used in the system, these microphones have to be completed with the extension module ARM-880RCE for each slave unit so that also the additional zones can individually be selected. Connect the cable (49) of the zone paging microphone to the jack on the lower side of the extension module. If re quired, connect the plug (58) of the extension module to the next extension module.

Address each extension module with its DIP switches (50):

Module	For the zones	Set DIP switch No. x to position ON
1	9-161
2	17-242
3	25-323

4.8 Power supply and emergency power supply

Finally connect the supplied mains cable to the mains jack (27) first and then to a socket (230 V/50 Hz).

For continuous operation of the matrix router in case of mains failure, connect a 24 V emergency power supply unit (e. g. PA-24ESP from MONACOR) to the contacts BATT SUPPLY + and - of the screw terminal EMERGENCY (30).

5 Basic Settings

Make the following basic settings at the matrix router for setting it into operation. Do not yet switch on the unit for the time being.

1) The DIP switches (28) must be set as follows:

Unit	For the zones	Set switch DIP ... to position ON
master unit	1 - 8	MASTER
slave unit 1	9-16	SLAVE 1
slave unit 2	17-24	SLAVE 2
slave unit 3	25-32	SLAVE 3

Notes: The switches must be actuated with the unit switched off. When the unit is switched on, there is no change of function. If the master unit is set in the wrong way, the signals of the inputs LINE 1 - 4 (34) and LINE / MIC 5 - 8 (36) cannot be routed to the zone outputs (19).

2) Press down the button REMOTE WALL CTRL (25) of the zones to which a wall module is connected.
3) Set the sliding switches (37) of the inputs LINE / MIC 5 - 8 to the corresponding position:
LINE = for an audio unit with line output
MIC = for a microphone
PHANTOM = for a microphone requiring a phantom power (46 V)

The next steps merely serve as an aid, however, other ways of proceeding are possible as well.

4) Set all controls (20, 23, 24, 26, 31, 32, 35, 39, 41, 42) on the rear side to mid-position, however, turn the controls GAIN of the inputs which are not used to the left stop to position “—”.

5) For the time being, set the controls MIC 1 (6) and SOURCE (7) of each zone to mid-position and the control MASTER (8) to position "0".

6) First switch on the audio sources connected and the matrix router, then the power amplifiers or active speaker systems connected to the zone outputs (19).

7) In each zone select the input of the inputs 1–8 to be heard at highest volume: Press the button SOURCE ▲ or ▼ (9) repeatedly until the display (3) shows the number of the input (L1 ... L8). Then confirm the selection with the button ENTER (14) within 10 seconds. Adjust the desired volume with the control MASTER (8) and with the volume control of the power amplifier or the active speaker system.

Note: Select the signal input of the zones to which the wall module ARM-880WP1 or ARM-880WP2 is connected with the button BGM ALL (17) or directly at the module with the buttons SOURCE (64).

8) The controls GAIN (35) of the inputs LINE 1 - 4 allow to adapt the input sensitivity to the output level of the units connected and to equalize differences in volume occurring when switching over the inputs.

9) The controls GAIN (23) allow to adapt the output level to the input sensitivity of the connected power amplifier or active speaker system for each zone. However, the controls also allow to limit the output level so that an excessive volume cannot be adjusted by mistake with the controls MASTER.

10) Adjust the sound separately for each zone with the controls (20). The control HF is intended for the high frequencies and the control LF for the low frequencies.

11) If a microphone has been connected to the jack MICROPHONE 1 (40), make an announcement via this microphone. Adjust the input sensitivity with the control GAIN (41) and the desired volume for the announcements with the controls MIC 1 (6) separately for each zone. The sound for the announcements can be adjusted with the controls LF and HF (42).

12) If a zone paging microphone ARM-880RC is connected;

a) Set the controls CHIME (44) and MIC (45) at the microphone to mid-position for the time being.

b) Select with the switch CHIME (43) if a chime is to sound prior to an announcement when pressing the button TALK (52), and if so, which type:

2-TONE = 2-tone chime

OFF = no chime

4-TONE = 4-tone chime

c) Press the button ALL CALL (53) so that an announcement can be heard in all zones.

d) Keep the button TALK pressed, possibly wait for a chime and make an announcement via the microphone. Adjust the volume of the announcement separately for each zone with the controls PAGE (24) at the matrix router.

e) If required, change the volume ratio of chime and announcement with the controls CHIME (44) and MIC (45).

f) If two zone paging microphones have been connected, adjust the volume ratio of the microphones with the controls GAIN (39).

g) To mark the zone buttons (57), a label (56) is provided which can be removed and replaced, if required. The same label is also available at the extension modules ARM-880RCE.

13) Feed an audio signal to the wall module ( chapter 6.3) or to the additional input of the zones where the wall module ARM-880WP1 or ARM-880WP3 is connected or the additional audio input (22) is used. In each case select the input with the buttons SOURCE (9, 64) (shown on the display by an "L") and adjust the volume with the control REM. SOURCE ... GAIN (26).

14) If the alarm inputs of the screw terminal FIRE ALARM (29) are used, trigger an alarm for each zone (bridge the contact for one zone and the contact G). Adjust the volume of the alarm signal for all zones of a matrix router with the control TONE OUTPUT (31).

15) When the input EMC IN of the terminal EMERGENCY (30) is used, feed an (emergency) signal to the input and adjust the volume for all zones with the control EMC INPUT (32).

6 Operation

6.1 Matrix router ARM-880

Switch on the unit with the POWER switch (1). The power indication (2) lights up. The zone displays (3) show the selected signal source for each zone. The monitor display (11) shows the zone selected for monitoring via the integrated speaker.

6.1.1 Selecting the signal sources for the zones

For the zones to which the wall module ARM-880WP1 or ARM-880WP2 is connected, the signal source can only directly be selected with the buttons SOURCE (64) at the module. The corresponding buttons SOURCE (9) at the matrix router have no function.

1) Press the button SOURCE ▲ or ▼ (9) repeatedly or keep it pressed to select the signal source. The display (3) shows the source:

$$ \begin{array}{l} \text { L 1 - L 8 } = \text { signals of the inputs LINE 1 - 4 } \ \text {(34) and LINE / MIC 5 - 8 (36)} \end{array} $$

$$ \begin{array}{l} \text { L } = \text { signal of the additional input(22) } \ \text { or of the wall module connected(ARM- } \ \text { 880WP1,ARM - 880WP3) } \end{array} $$

$$ \begin{array}{l} \text { OF } = \text { none of these signals has been } \ \text { selected(OFF) } \end{array} $$

2) After the selection the number on the display flashes for 10 seconds. Press the button ENTER (14) during this time to confirm the selection. Otherwise the previous selection is kept. A procedure of selection can be stopped at any time with the button ESC (15).
3) For selection of the same signal for all zones (even those to which a wall module is connected), this can be made conveniently with the button BGM ALL (17). After selection press the button ENTER.
4) If required, readjust the volume of the selected signal source separately for each zone with the control SOURCE.
5) Adjust the overall volume of the mixed signal of signal source and announcements via MIC 1 (Chapter 6.1.4) separately for each zone with the control MASTER (16).

Hint: When the signals of the inputs 1 - 8 cannot be heard in any zone, check the position of the DIP switches (28) [ chapter 5, step 1].

6.1.2 Announcements via MIC 1

If a microphone has been connected to the jack MICROPHONE 1 (40), announcements for certain zones or for all zones can be made via this microphone.

1) Adjust the volume for the announcements separately in each zone with the control MIC 1 (6). Set the controls of the zones to "0" where the announcements are not to be heard.
2) The microphone signal can be added to the signal source selected for each zone or it can interrupt the signal of the source (automatic talkover). Press the button PRIORITY (10) for the zones where the signal of the source is to be interrupted for an announcement. The LED MIC 1 (4)

lights up. Press the button PAGE ALL (18) to activate the automatic talkover function for all zones.

Note: After switching the matrix router off and on again, the automatic talkover function is deactivated. If required, reactivate the function.

6.1.3 Monitoring the zones via the speaker

To check the zones or to select a signal source for one zone, each of the eight zones can be monitored via the integrated speaker. This speaker exactly reproduces the signals presently heard in the selected zone.

1) Press the button ZONE SELECT (12) repeatedly or keep it pressed to select the zone. The display (11) shows the zone number.
2) After selection, the number flashes on the display for 10 seconds. Press the button ENTER (14) during this time to confirm the selection. Otherwise the previous selection is maintained. A procedure of selection can be stopped at any time with the button ESC (15).
3) Adjust the monitoring volume with the control MONITOR (16). The LED chain OUTPUT LEVEL (13) shows the signal level of the selected zone output (19).

6.2 Zone paging microphone ARM-880RC

1) Switch on the microphone with the POWER switch (48). The POWER indication (55) lights up.
2) First select the PA zones in which the announcement is to be heard with the buttons SPEAKER ZONES (57), if necessary use the buttons of the extension modules ARM-880RCE. To select all zones, press the button ALL CALL (53). The selected zones are in each case indicated by an LED showing blue and can also be deselected with the corresponding button or the button ALL CALL.

If an announcement is made from a second zone paging microphone, the LEDs of the zones where the announcement can be heard show orange. Then these zones cannot be selected.

3) Keep the button TALK (52) pressed for an announcement, possibly wait for the chime, and then speak. If the LED of the button TALK flashes, no zone has been selected.
4) The microphone signal is shown by the LED chain OUTPUT LEVEL (54). The red LED should only shortly light up. If it lights up for a longer time, speak at a lower volume, increase the distance to the microphone or turn the control MIC (45) counter-clockwise accordingly.

If the volume of the announcement is too low, turn the control clockwise accordingly, speak at a higher volume or move closer to the microphone.

Note: The announcements from a zone paging microphone take priority over other signal sources and interrupt their signals in the selected zones. Only alarm signals take an even higher priority ( chapter 4.3).

6.3 Wall modules

6.3.1 ARM-880WP1 and ARM-880WP2

As soon as the matrix router is switched on, the power LED (65) of the module lights up and the display (63) shows the selected signal source:

L 1-L 8 = signals of the inputs LINE 1 - 4 (34) and LINE / MIC 5 - 8 (36)

L = signal of the additional input (22) or wall module (step 3)

OF = none of these signals is selected (OFF)

1) To switch on another signal source, press the button SOURCE ▲ or ▼ (64) repeatedly or keep it pressed.
2) Adjust the desired volume with the control SOURCE LEVEL (66). If the volume cannot be adjusted to a sufficiently higher volume, turn up the corresponding control SOURCE (7) and/or MASTER (8) at the matrix router accordingly.
3) A microphone* may be connected to the jack MIC INPUT (60) of the module ARM-880WP1 and a unit with line output to the RCA jacks LINE INPUT (59) to be able to hear their signals in the corresponding zone.

a) Use the button SOURCE ▲ or ▼ to switch the display indication to "L". Thus, the jacks LINE INPUT and MIC INPUT are selected.
b) Set the control SOURCE LEVEL to mid-position approximately and turn up the control LINE LEVEL (61) for the connected audio unit and/or the control MIC LEVEL (62) for the microphone so that the signals can be heard well. If an input is not connected, set the corresponding control to "0".
c) Adjust the definitive volume with the control SOURCE LEVEL.

6.3.2 ARM-880WP3

As soon as the matrix router is switched on, the power indication (71) at the module lights up.

1) Connect two microphones* to the jacks MIC INPUT (67) to be able to hear their signals in the corresponding zone.
2) Adjust the volume for the microphones with the controls MIC LEVEL (69). When a microphone input has not been connected, set the corresponding control to "0".
3) When a signal source has been selected at the matrix router for the corresponding zone, the microphone signals can be added to the signal source. The signal source can also be muted with the button LINE MUTE (70) so that only the microphone signals can be heard.
4) The sound can be adjusted separately for each microphone with the controls (68). The controls HF are intended for the high frequencies and the controls LF for the low frequencies.

* It is also possible to use microphones requiring a 15 V phantom power. However, no microphone with unbalanced connection must be used; it may be damaged by the present phantom power.
