AtlasIED - IED5404DZM

The 5404DZM Digital Zone Manager provides processing and management of four (4) paging zones assigned from an IED 5400 Announcement Control System. It also provides line level audio outputs to a paired four-channel amplifier unit. Digital Signal Processing (DSP) is provided on each of the four (4) output channels. This includes: input level controls, paging routing, automatic ducking of background music, equalization (high pass filters, low pass filters, up to 40 milliseconds of delay, plus up to 7 parametric bands per amplifier channel). IED’s patented ambient analysis and control provides automatic level adjustment with two (2) Sensor Input Channels per amp channel.

The 5404DZM provides backup amplifier switching by switching up to four (4) loudspeaker loads from a 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.
