Paging Microphone Console to suit A 4480A 8x8 Matrix

The A 4481 paging console is an extremely flexible addition to the A 4480A audio switcher. The consoles can be used for multi zone paging with the facitily to store and recall multiple zones to a single button. The recall functions can also be labelled via a USB keyboard which can be plugged into the rear of the unit.  The labels will then be displayed on the highly functional and attractive LCD. An example might be a label “”sales””.

An emergency paging over-ride facility is accessed by a combination of an illuminated push button switch and a PTT (push to talk) switch. This combination removes the possibliity of accidentally activating the emergency over-ride facility. When activated, emergency paging will be forced through to all zones regardless of any zones which were set to be locked out.

A maximum of 8 paging consoles can be connected to the A4480A at the same time. These work on a “first in, best dressed” arrangement. The consoles can be cascaded together or wired back to the A 4480A.

Each unit must be assigned an ID number through DIP switch settings on the rear of the unit. 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.
