Q-Matrix 88 is a 3 rack unit multizone paging and source selection system that offers unprecedented flexibility for multizone paging and source routing applications. 8 program inputs are available to each of 8 zone outputs. With LCD indication for program/local input selection, zone output level, paging enable/disable and network busy, the Q-Matrix 88 provides extensive status indication to the user. The Q-Matrix 88 is also expandable to 24 zones with the addition of a third Q Matrix 88. Paging stations are available in 8 or 16 zone models allowing paging into any individual zone, any combination of zones or All Call. Remote control panels are also available, allowing source selection and volume control from within each remote zone. These panels each have 2 inputs, both mic and line with the ability to mix locally. Both paging stations and remote control panels connect via inexpensive and industry standard CAT5 cable network. An overall priority input is also provided for emergency or evacuation signals.
