The 1544ZOP 4x4 Smart Zone Output Processor provides all the network audio routing and zone digital signal processing functions of a DNA2404D integrated network amplifier unit. This includes Dante^® network audio input, equalization, level control, and IED’s patented AlwaysHEAR^™smart ambient analysis automatic level adjustment. AlwaysHEAR^™. ensures the audio levels are automatically adjusted to always be set at the perfect sound level. The 1544ZOP provides four line-level balanced analog audio outputs for driving external amplifiers or powered line arrays. The 1544ZOP integrates with AtlasIED’s GLOBALCOM^®.IP announcement controller, or may be used in stand-alone applications. Optionally, the processed zone output audio may be routed back out over the network as Dante digital audio. 

In addition to the four zone outputs, the 1544ZOP has four balanced line-level analog inputs that may be used as automated test inputs associated with the four zone outputs. Alternately, the analog inputs may be routed out over the network as Dante digital audio for such uses as for background music or auxiliary audio sources. 

The 1544ZOP also provides eight (8) logic inputs. Four of the inputs are standard closure detection and four are supervision capable, which provides the additional means to detect open or short conditions on the incoming links. 

Inputs are provided for connecting up to eight (8) 540S ambient noise sensors (2 sensors for each output channel). This allows the output of each channel to be automatically adjusted in real time based on the measured ambient noise level in the zone. 

The 1544ZOP may be configured from the GLOBALCOM.IP System Management Center (SMC) or via the open-standard SNMP (Simple Network Management Protocol).
