Redback® A 4480B 8 In to 8 Out Audio Switcher
2.4 CONNECTING POWER
Next, connect power to the unit. (see Fig 2.4A)
The A 4480B 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.
ALERT - EVACUATION MODULE
The Alert/Evacuation module has multiple chime options, a recordable
voice-over message and adjustable alert to evacuation tone switch-over times.
These options are selectable inside the unit, via the BCD rotary switch and
DIP switches located on the alert/evacuation module (refer to below settings).

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 4480B is unlocked. To unlock, press "confirm"
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.
