OVERVIEW
The A 4486 paging microphone is a simple to use and elegant desk top design which provides paging to a single zone. 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 back-
ground music.
The A 4487 Line out box provides a MIcrophone or Line level output which can be connected directly to the input of an
amplier. Connection between the A 4486 and A 4487 is via a Cat5e cable which carries power and the balanced audio
output from the microphone. Power for the system can be connected at the microphone or the Line Out box.

Typical connection of the A 4486 and A 4487 with a single amplier
Connecting the A 4486 and A 4487
The Microphone and Line out box are connected by a CAT5e cable 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 500mA is required to power the system. Power connection can be made at the microphone
itself via a 2.1mm DC Jack or by connecting power to the Line Out Box via a 2 way screw terminal. Power is then fed
through the CAT5e cable to feed the system from either end.
If powering the system at the A 4486 end 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 Line Out Box 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.

RJ45 cabling conguration (586A ‘Straight through’)
System components are connected using “pin to pin” conguration RJ45 data cabling as shown in g 4. When installing
ensure all connections are veried with a LAN cable tester before switching any system component on.
Failure to follow the correct wiring conguration may result in damage to system components.

Paging Console
Activating 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 5 shows the position of this connector.
To activate the background music, move the push to talk 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. The volume is adjusted by the
BGM volume trimpot on the rear of the microphone.
If the switch is moved to the “Page” position the background music will stop and paging will be active.
If the switch is in the centre position the BGM and paging are not active.
