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 AtlasIED 5400 Announcement Control System. It 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 ducking of background music, 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 comes back into the 5432DZM and then is 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 primary power amplifier to a backup when a failure is detected. It also contains integrated supervision that monitors each signal path and reports any failures to the 5400ACS.

The mainframe requires two (2) rack units (3.5″) of vertical space in a 19″ equipment rack/cabinet. All cooling is front to back.
