Digital Zone Manager (PZA)
GLOBALCOM ® EN54-16 Digital Zone Manager (Up to 32 Zones)
The 5432DZM Digital Zone Manager provides processing and management of up to 32 paging zones assigned from an IED 5400 Announcement Control System. Provides line level audio outputs to a paired four (4) channel amplifier unit. Digital signal processing (DSP) is provided on each of the four (4) output channels. This includes: gain control for the paging input, page routing, automatic background music ducking, equalization (high and low pass filters, up to 7 parametric bands per amplifier channel, and up to 40 milliseconds of delay). The paired amplifier outputs return to the 5432DZM and are then distributed to up to eight (8) speaker line outputs per amplifier channel. Each of the 32 speaker lines is supervised.
The 5432DZM provides automatic backup amplifier switching by switching groups of eight (8) speaker loads from the main power amplifier to a backup when a fault is detected. It also contains built-in supervision that monitors each signal path and reports any faults to the 5400ACS.
The main unit requires two (2) rack units (3.5") of vertical space in a 19" equipment rack/cabinet. All cooling is from front to back.
- 4 input x 32 output zone manager for 4 banks of 8 speaker outputs.
