OVERVIEW
The A 4488 paging microphone is a simple to use and elegant desk top design which provides up to 4 zones of paging. It
allows the operator to manually select any zone or any combination of zones. Also included is an All Call & Cancel button.
A pre-announcement chime is available at the paging console and through the PA system. Both of these are set by DIP
switches on the rear of the unit. Provision has also been made on the rear of the unit for a 3.5mm BGM input for
background music.
A maximum of two paging consoles can be connected to the A 4489 Audio Switcher at the same time. These work in a
“rst in, best dressed” arrangement. Each unit must be assigned an ID number through DIP switch settings on the rear of
the unit.
The A 4489 Audio Switcher provides a Microphone level or Line level output which can be connected directly to the inputs
of up to four ampliers to provide up to four zones of audio. Connection between the A 4488 and A 4489 is via a Cat5e
cable which carries power and the balanced audio output from the microphone.

Connecting the Paging Console/s and Audio Switcher
The Paging console/s and Audio Switcher are connected by a CAT5e cables with a maximum run distance of 300 metres.
This CAT5e cable can be connected to either of the two RJ45 ports provided on the rear of the microphone. A 24V DC
power supply rated at a minimum of 1A is required to power the system. Power connection must be made by connecting
power to the Audio Switcher via a 2.1mm DC Jack. Power is then fed through the CAT5e cables to supply power to the
paging consoles. We recommend tting the power supply with the Altronics P 0602 2.1mm DC Plug with collar which can
be screwed onto the DC socket to prevent accidental disconnection of power.
The balanced audio output from the microphone is transmitted down the CAT5e cable to the Audio Switcher which splits
and converts the signal to microphone and line level outputs. These are provided as screw terminal connections.
Volume controls for the microphone volume and chime volume are located on the rear of the microphone.
Connection Congurations
There are three basic different congurations for switching the audio output from the A 4489 Audio Switcher to the
output zones.
Option 1 : Individual Zone Ampliers using Microphone Level Signals
The audio from the paging console/s is fed down the Cat5e cable to the A 4489 audio switcher. Take the low level
balanced signal from the “Mic Out” terminals on the rear of the A 4489 and feed them back into the “Audio In”
terminals on the rear of the A 4489 as shown in Fig 3.
The audio from the “Zone 1” to “Zone 4” terminals are then fed into individual amplifers to provide the audio for the
four zones. The audio from these output terminals are switched internaly by relays and are not present unless the zone is
activated by the paging console/s.
Use this method if using ampliers with low level balanced inputs. If the ampliers used have line level inputs use the
conguration outlined in option 2.

Option 2 : Individual Zone Ampliers using Line Level Signals
The audio from the paging console/s is fed down the Cat5e cable to the A 4489 audio switcher. Take the line level
(1V balanced signal) from the “Line Out” terminals on the rear of the A 4489 and feed them back into the “Audio In”
terminals on the rear of the A 4489 as shown in Fig 4.
The audio from the “Zone 1” to “Zone 4” terminals are then fed into individual amplifers to provide the audio for the
four zones. The audio from these output terminals are switched internaly by relays and are not present unless the zone is
activated by the paging console/s.
Use this method if using ampliers with Line level balanced inputs. If the ampliers used have mic level inputs use the
conguration outlined in option 1.
Fig 4
Option 3 : One Zone Amplier using Mic or Line Level Signals and individual speakers for each zone
The audio from the paging console/s is fed down the Cat5e cable to the A 4489 audio switcher. Take the line level
(1V balanced signal) from the “Line Out” terminals or the low level balanced signal from the “Mic Out” on the rear of the
A 4489 and feed them into the audio inputs of the zone amplifer as shown in Fig 5.
The speaker output of the zone amplier is then fed into the “Audio In” terminals of the audio switcher.
The audio from the “Zone 1” to “Zone 4” terminals are then fed directly into the speakers to provide the audio for the
four zones. The audio from these output terminals are switched internaly by relays and are not present unless the zone is
activated by the paging console/s.

General Paging
To page to a zone select the desired zone/s by pressing the buttons 1-4 or by pressing the “All Call” button if all zones are
desired. Make sure the switch is in the centre position before selecting the zones. The selected zones’ LED’s will illuminate
to indicate they have been pressed. Move the “Push to talk” switch down to the “Page” position and speak into the
microphone. Release the PTT switch when nished. The selected zones’ LED’s will ash for a few seconds after paging has
nished. While these LED’s are still ashing paging can be directed to these zones again by simply moving the PTT switch
back to the “Page” position.
If two paging consoles are connected to the system one console will be “Locked Out” when the other is in use.
Fig 6 illustrates an example of two consoles being used together. The rst console is being used to page to zones 1 and 2.
The second console is inactive while the rst console is in use.
NOTE : If both paging consoles are tted then the ID must be set for each. See the Dip switch setting for details.
Paging console 1 has zones 1 & 2
selected and the
“Push to Talk” switch
moved to the“Page” position.
The LED’s on zone 1 and
zone 2 are illuminated.

Connecting the BGM (Background Music)
Backgound music can be supplied to the paging system by connecting an audio source such as a mobile phone, tablet etc.
to the 3.5mm input jack on the rear of the paging microphone. Figure 7 shows the position of this connector.
To activate the background music, rst make sure the Push to Talk (PTT) switch is in the centre position and then select
the zones to receive the background music. The selected zones led indicators will ash to signify they have been selected.
Next move the PTT switch to the up position which is lablelled “Lock On”. While the switch is in this position and only this
position will the background music will be piped out to the zones selected.
The volume is adjusted by the BGM volume trimpot on the rear of the microphone.
If the PTT switch is moved to the “Page” position the background music will stop and paging will be active.
If the PTT switch is in the centre position the BGM and paging are not active.
If background music is required again to the same zones as previously selected, then all thats needed to initiate it again is
to move the PTT switch back to the “Lock On” position.
If the BGM is to be piped to different zones then it is only a matter of selecting the new zones, and then moving the PTT
switch to the “Lock On” position.

Understanding the BGM (Background Music) and Paging Relationship with multiple paging consoles
The background music source is connected to the rear of the paging console as shown in Fig 7. If two paging consoles
are in use, a background music source could be connected to either console, operating on a First In, First serve basis. But
Altronics does not recommended using more than one BGM input.
Unfortunately when the BGM is active on one paging console there is no visual indication of this fact on the other
console. So having two BGM sources would become confusing.
When the BGM is active on Paging console 1 it can be over-ridden by general paging on Paging console 2 and vise versa.
If BGM is active on paging console 1 and paging is to be initiated by this same console then the PTT switch will need to be
moved to the “Page” position. Once the PTT switch is moved off the “Lock On” position, then the BGM stops.
Fig 8a and 8b illustrate a typical example of BGM on one console and paging on the other console.
In Fig 8a paging console 1 has zones 1 & 2 selected and the PTT switch moved to the “Lock On” position. Background
music is being fed to zones 1 & 2. The LED’s on zones 1 & 2 are illuminated indicating which zones have background
music. Paging console 2 has the PTT switch in the OFF position which means its not active and has no visual indication that
the BGM is active to zones 1 & 2.
In Fig 8b Paging console 2 has the PTT switch in the “Page” position and zones 3 and 4 are now active for paging.
Paging console 1 still has the PTT switch in the “Lock On” position. The LED’s on zones 1 & 2 stay illuminated indicating
which zones have background music. But since console 2 is now paging, console 1 has been over-ridden and the paging
audio is now sent to zones 3 & 4. The system busy led is illuminated on console 1 indicating the system is busy and that
console 1 has now been “Locked Out” until console 2 nishes paging. The background music has been disconnected.
Once console 2 nishes paging the BGM will be re-stored to zones 1 and 2.
Paging console 1 has zones 1 & 2
selected and the PTT switch
moved to the“Lock On” position.
Background music is fed to zones 1 &2.
The LED’s on zones 1 &2 are illuminated
indicating which zones have
background music.
