Overview
1.0 OVERVIEW
1.1 INTRODUCTION
Designed to meet the demands of todays complex installations, this unit is a very versatile cost effective public address/
background music control system.
In total there are 16 inputs:
• 1 emergency paging input
• 1 alert/evac input
• 6 auxiliary inputs and 2 auxiliary/line inputs
• 2 zone paging inputs
• 1 priority input
• 8 local inputs
Operation is as follows:
Emergency Paging mutes all other inputs, including alert/evac signals and transmits to all zones. Note: the emergency
paging input will accept either a low level balanced mic signal (3mV) or a high level balanced signal (700mV). This enables
sources other than a microphone to be used. For example, the output of a building occupancy warning system could feed
into this input and transmit either verbal messages from the microphone or the alert & evacuation tones. All on an “all
call” basis.
Alert/Evac signals mutes all other inputs, except emergency paging and transmits to all zones.
Zone Paging (via optional A 4481 paging station) mutes auxiliary signals and transmits to selected zones. Zone paging
may be prohibited for each zone from the front panel on the mic console.
Priority Input mutes auxiliary signals and transmits to selected zones. This input has the same priority as the A 4481
paging stations and works on a “rst in best dressed” basis. This input is enabled via a trigger input or vox enabled dual
RCA input.
Local Inputs (1-8 via optional A 4478 wall plate) mutes any auxiliary source selected to that zone. Local inputs can be
congured for either balanced mic or line operation.
Aux inputs (1-8) can be switched to any zone or combination of zones.
Each of the eight auxiliary inputs have tamper proof volume, treble and bass controls, plus a signal presence indicator.
Volume controls are provided for each zone output.
A programmable LCD indicates which input is selected to which outputs.
Tamper proof volume controls and signal presence indicators are provided for local microphone paging and emergency
microphone paging.
Remote selection wallplate (A 4490) may be connected via Cat5e cable to each zone. This wallplate enables selection of
any auxiliary input source, volume adjustment of that zone plus the option to connect a local input source (mic or line) via
the optional A 4478 wallplate.
Memory presets are programmable to provide easy recall of certain system congurations including a default setting, last
memory setting and 4 memory presets. This is selected from the front panel, or remotely via the optional A 4476 preset
selector wallplate (see 5.4, page 28).
System lockout feature to prevent unauthorised adjustment of system settings.
WARNING
System components are connected using standard “pin to pin”
conguration RJ45 data cabling. When installing ensure all connections
are veried before switching any system component on.
Failure to follow the correct wiring conguration may result in damage to
system components.
For the correct wiring conguration, see section 6.0 “Troubleshooting”.

Setup Guide
2.1 SETUP GUIDE
This is intended to be a quick setup for a minimal install. Section 3.0 will build on the initial setup and cover the installa-
tion of peripheral connections and more in depth detail on programming the unit. In this basic conguration we will use
a setup in a bar as an example. The install requires 2 audio sources, a tuner and a dvd player. This audio will be fed to 4
different zones, the main bar, the beer garden, the restaurant, and the kitchen. All adjustments will be made from the
front panel of the A 4480.
A programming template in PDF format is available to download from the Altronics website. This allows you to map your
inputs, outputs, zone names, source names and presets before you commence programming. A printed copy is located at
the end of operating manual (see section 9.0).
2.2 CONNECTING AUDIO SOURCES
Begin by connecting the audio sources. (see Fig 2.2A).
1 - Use a dual RCA lead to connect the INPUT 1 on the A 4480 to the audio output sockets of the source eg: tuner.
2 - Use a dual RCA lead to connect the INPUT 2 on the A 4480 to the audio output sockets of the source eg: DVD player.
If more audio sources are required, connect them to inputs 3 -8 on the A 4480.

230V AC EARTHED MAINS LEAD
24V DC 2A POWER SUPPLY
(BACKUP SUPPLY)
Setup Guide
2.4 CONNECTING POWER
Next, connect power to the unit. (see Fig 2.4A)
The A 4480 can be powered from either a 24V DC rated source or mains rated 220-240V AC @ 50Hz.
24V DC can be supplied via a 2 way pluggable terminal. The supply would need to be able to deliver a continuous 24V DC
@ 2A. It is not recommended that the unit is continually powered in this manner. Rather the unit should be run of 220-
240V AC via the supplied 3 pin mains lead. The 24V DC input should be connected to a backup supply which switches on
in the event of mains power failure.
Fig 2.4A
2.5 CONFIGURING THE INPUTS TO OUTPUTS/ZONES
Once the unit is switched on the title screen with the software version will momentarily appear. The unit will then go into
a self check mode and search for any externally connected wall plates & paging consoles. Once the check is complete, the
main screen appears. Before commencing any programming, ensure the A 4480 is unlocked. To unlock, press “conrm”
and “cancel” buttons at the same time. The main screen is shown below in Fig 2.5A. The left side of the screen shows the
output zones 1-8, while the input sources are displayed on the top of the screen.
There is also a local audio and paging console option shown which will not be discussed in this quick setup section. This
will be covered in section 3.
Zone 1 refers to the zone 1 output which in our example was the main bar. Zone 2 refers to the beer garden and so on.
To make these easier to remember the zone names can be labelled via the use of a keyboard. However this will not be
covered here. Please refer to section 4.2 for more details.
The inputs work in the same manner. Input 1 in our example was the tuner and input 2 was the DVD player. Once again
these can also be labelled.

Zone Selection Buttons
2.5.1 Routing audio to a zone
In our example we have 2 input sources and 4 zones. Selecting which zone receives which audio is very simple. The but-
tons on the left side of the LCD are the zone selection buttons.(see Fig 2.5B)
Fig 2.5B
For each zone there are 8 possible inputs to select and the off position which is the default. Each time one of these zone
selection buttons is pressed the next input source is routed to that particular zone. This is displayed on the screen by an
“*”. For instance in our example we want to route the DVD player (input 2) to the main bar (zone 1). Pressing zone se-
lection button 1 twice will move the “*” 2 positions from the off position to input 2, thus routing the DVD player to zone
1. Continuing to press the zone 1 button will move the “*” through all the inputs and then to the off position where the
“*” will no longer be visible.
By pressing the zone 2 selection button twice we can also route the DVD player to zone 2 and so on.
In the example below in Fig 2.5C (input 2) is routed to the main bar (zone 1), the beer garden (zone 2) and the restaurant
(zone 3). While the tuner (input 1) is routed to the kitchen (zone 4).

Setup Guide
2.6 ADJUSTING THE BASS, TREBLE AND INPUT VOLUMES
The system is now setup and ready to run.
The eight audio inputs all have separate bass, treble and volume controls, which are accessible on the front panel as
shown in Fig 2.6A. These tamper proof controls need to be adjusted with a screwdriver and set to your desired levels. A
signal present LED on each input provides instant feedback on the presence of audio from the input sources.
A perspex cover is provided which can be screwed on to the front panel which covers these bass,treble and input volume
pots to prevent tampering.
Fig 2.6A
Fig 2.7A
3.0 LOCAL AUDIO & PAGING CONSOLE OPTIONS
3.1 LOCAL AUDIO CONFIGURATION
The local audio conguration on the LCD indicates zones that have a local audio source connected via the A 4478 local
audio wall plate and the A 4490 zone wall plate (see section 5.2 and 5.4 for connection details).
If a local audio source is detected on a zone wall plate it is displayed on the LCD via an asterisk (*) in the local section. For
example, if zone 1 had an A 4478 tted with a live audio source connected, the system would detect the presence and
display an “*” in zone 1 as shown in g 3.1A. This automatically overrides any input source selected via the front panel.
2.7 ADJUSTING THE PAGING CONSOLE AND EMERGENCY INPUT VOLUMES
The emergency microphone and paging microphone controls are also shown in Fig 2.6a. The signal present leds indicate
when a signal is present and the volume adjusts the audio level from these two microphones.
2.8 ADJUSTING THE ZONE VOLUMES
The 8 zones also each have volume controls which can be set to the desired levels on the front of the unit (see Fig 2.7A)

Setup Guide
3.2 PAGING CONSOLE CONFIGURATION
The paging console conguration on the LCD is used to display which zones are currently accessible by the paging con-
soles. All output zones can be programmed to be “locked out” from paging. If a zone is locked out, general paging will
not be routed to that zone. However emergency paging will override locked out zones and page all output zones. An
example may be an output zone such as a carpark. General paging may not be required but emergency paging would still
be required.
3.3 CONFIGURING THE PAGING CONSOLE LOCKOUT ON THE LCD
To congure a zone to be locked out from general paging return to the main screen, if not already there. Press the PA on/
off button. The screen shown below in g 3.1B should appear.
Fig 3.1A
Fig 3.1B
To lock a zone out from the general paging, use the buttons labelled 1-8 left of the LCD. Pressing button 1 will toggle
zone 1 ON or OFF depending on its current status. Pressing button 2 will toggle zone 2 ON or OFF etc. If the zone is left in
the OFF state, paging to this zone will now be locked out. Note: this lock out will be overriden by emergency paging.
3.4 CONFIGURING THE PROGRAM ISOLATE ON THE LCD
The A 4480 can be setup to isolate selected input sources from a zone, so these inputs are isolated or BLOCKED for that
zone. Examples might include music being isolated or blocked to the “car park” or common areas.
To isolate an input from a zone, press the isolate button on the front of the A 4480. The screen shown in Fig3.1C will ap-
pear. In this example input 1 is isolated from zone1 as indicated by the letter “I”. To isolate the inputs use the buttons 1-8
on the left of the screen to select the zone and then continue to press the selected number to scroll through the inputs. A
circle on the screen indicates the cursor position. Once in position, press the isolate button and the cursor will change to
an “I”. The corresponding input is now isolated from that zone. Pressing the isolate button again will turn off the isolate.

Setup Guide
4.0 EMERGENCY OVERRIDES & PRIORITIES
4.1 PRIORITIES
There are 5 levels of priority in the A 4480.
Level 1 The emergency microphone is a hard wired microphone which connects to the 3 pin XLR connection as shown
in the full connection diagram. This has top priority and will override all other inputs. The gain of this microphone
is set by the screwdriver adjust controls on the front of the A 4480. A signal presence LED indicates signal being
received from the microphone.
Level 2 The A 4481 paging console (optional) has an emergency paging function which will override all other inputs
except the emergency microphone. See section 5.1 for details. The gain of this microphone is set by the screw
driver adjust controls on the front of the A 4480. A signal presence LED indicates signal being received from the
microphone.
The priority input operates on the same priority level as the A 4481 paging consoles. (See section 5.2 for details)
The priority input and the paging consoles work on a First In Best Dressed basis.
Level 3 The alert/evacuation tones provide the next level of priority and will override all inputs except the emergency
paging microphone, the paging consoles (if tted) when used in emergency paging mode and the priority input.
Level 4 The A 4481 paging console when operating in standard paging mode has the next level or priority and will over
ride all local zone inputs and line inputs.
Level 5 The A 4478 local input wallplate (optional) will override audio routed to the same zone the A 4478 is connected
to.
Input audio sources 1-8 have the lowest priority and will not override anything.
4.2 PRIORITY INPUT
The priority input can be triggered via a closing contact or a vox operated audio input. This makes it useful for applications
such as telephone paging or the playing of the ODE in RSL clubs when used in conjunction with a timer.
