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 AlwaysHEARTM 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.
